Vulnerability Information

Severity: High
Vulnerability Published: N/A
Patch Published: N/A
CVE [?]: CVE-2008-6508
CPE [?]: cpe:/a:igniterealtime:openfire

Synopsis

The remote web server contains an application that is affected by an authentication bypass vulnerability.

Description

The remote host is running Openfire / Wildfire, an instant messaging server supporting the XMPP protocol.

The installed version of this software contains a design error in its admin interface in that it allows URLs starting with certain strings, such as 'setup/setup-', to circumvent its auth check mechanism. A remote attacker can leverage this issue to bypass authentication and gain administrative access to the application.

Based on the presence of this vulnerability, it is likely that the admin interface in the installed version is also affected by multiple cross-site scripting issues as well as a SQL injection vulnerability that allows an attacker to write files to disk and execute code at the operating system level. Nessus has not, though, checked for these other issues.

Solution

Upgrade to Openfire 3.6.1 or later.

Public Exploits

Target Network Port(s): 9090
Target Asset(s): Services/www
Exploit Available: True (Metasploit Framework, Exploit-DB)
Exploit Ease: No exploit is required

Here's the list of publicly known exploits and PoCs for verifying the Openfire AuthCheck Authentication Bypass vulnerability:

Metasploit: exploit/multi/http/openfire_auth_bypass
[Openfire Admin Console Authentication Bypass]
Exploit-DB: exploits/jsp/webapps/19432.rb
[EDB-19432: Openfire Server 3.6.0a - Admin Console Authentication Bypass (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.

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.
