Vulnerability Information

Severity: High
Vulnerability Published: 2009-10-19
Patch Published: 2010-09-14
CVE [?]: CVE-2009-4140
CPE [?]: N/A

Synopsis

A PHP application hosted on the remote web server allows uploading arbitrary files.

Description

The third-party Open Flash Chart component included with the version of OpenX hosted on the remote web server allows an unauthenticated attacker to upload arbitrary files to the affected system, by default in a web-accessible directory.

While Nessus has not verified this, it is likely that an attacker could exploit this to upload a script with, say, PHP code and then browse to that file, causing arbitrary code to be executed on the remote system subject to the privileges of the web server user id.

Solution

Either remove the 'ofc_upload_image.php' script in 'admin/plugins/videoReport/lib/ofc2' or upgrade to version 2.8.7 or later.

Public Exploits
