CVE [?]: CVE-2005-0595
CPE [?]: N/A

Synopsis

The remote web server is prone to buffer overflow attacks.

Description

The remote host is running a version of BadBlue HTTP server that has a buffer overflow vulnerability in 'ext.dll', a module that handles HTTP requests. An unauthenticated, remote attacker can leverage this vulnerability by sending an HTTP request containing a 'mfcisapicommand' parameter with more than 250 chars to kill the web server and possibly execute code remotely with Administrator rights.

Solution

Upgrade to BadBlue 2.60.0 or later.

Public Exploits

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

Here's the list of publicly known exploits and PoCs for verifying the BadBlue ext.dll mfcisapicommand Parameter Remote Overflow vulnerability:

  1. Metasploit: exploit/windows/http/badblue_ext_overflow
    [BadBlue 2.5 EXT.dll Buffer Overflow]
  2. Exploit-DB: exploits/windows/remote/16761.rb
    [EDB-16761: BadBlue 2.5 - 'ext.dll' Remote Buffer Overflow (Metasploit)]

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.
