CVE [?]: CVE-2008-4008
CPE [?]: cpe:/a:oracle:weblogic_server

Synopsis

The remote web server uses a module that is affected by a buffer overflow vulnerability.

Description

The remote web server is using the WebLogic plug-in for Apache (mod_wl), an Apache module included with Oracle (formerly BEA) WebLogic Server and used to proxy requests from an Apache HTTP server to WebLogic.

The version of this plug-in on the remote host is affected by a stack buffer overflow that is triggered when processing a request with an invalid parameter. An unauthenticated, remote attacker can leverage this issue to execute arbitrary code on the remote host.

Note that Nessus has not tried to exploit this issue but rather has only checked the affected module's build timestamp.

Solution

Install the latest web server plug-in as described in the vendor advisory above.

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 Oracle WebLogic Server mod_wl Invalid Parameter Remote Overflow (1150354) vulnerability:

Metasploit: exploit/windows/http/bea_weblogic_transfer_encoding
[BEA Weblogic Transfer-Encoding Buffer Overflow]
Exploit-DB: exploits/windows/remote/16796.rb
[EDB-16796: BEA Weblogic - Transfer-Encoding 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.

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.
