CVE [?]: CVE-2006-2926
CPE [?]: N/A

Synopsis

The remote HTTP proxy server is prone to a buffer overflow attack.

Description

The remote host appears to be running WinGate Proxy Server, a Windows application for managing and securing Internet access.

According to its banner, the version of WinGate installed on the remote host is affected by a buffer overflow vulnerability in its HTTP proxy service. An attacker with access to use the proxy may be able to exploit this issue to execute arbitrary code on the remote host.

Note that by default the service operates with LOCAL SYSTEM privileges, which means that a successful attack may result in a complete compromise of the affected system.

Solution

Upgrade to WinGate 6.1.3 or later.

Public Exploits

Target Network Port(s): 80
Target Asset(s): Services/www
Exploit Available: True (Metasploit Framework, Exploit-DB, Immunity Canvas, Core Impact)
Exploit Ease: Exploits are available

Here's the list of publicly known exploits and PoCs for verifying the WinGate POST Request Buffer Overflow vulnerability:

  1. Metasploit: exploit/windows/proxy/qbik_wingate_wwwproxy
    [Qbik WinGate WWW Proxy Server URL Processing Overflow]
  2. Exploit-DB: exploits/windows/remote/16690.rb
    [EDB-16690: QBik WinGate WWW Proxy Server - URL Processing Overflow (Metasploit)]
  3. Immunity Canvas: CANVAS

Before running any exploit against any system, make sure you are authorized by the owner of the target system(s) to perform such activity. In any other case, this would be considered as an illegal activity.

WARNING: Beware of using unverified exploits from sources such as GitHub or Exploit-DB. These exploits and PoCs could contain malware. For more information, see how to use exploits safely.
