Joomla! 'mosConfig_absolute_path' Parameter Remote File Include

critical Nessus Plugin ID 31095

Language:

Synopsis

The remote web server contains a PHP application that is affected by a remote file include vulnerability.

Description

The version of Joomla! running on the remote host is affected by a remote file include vulnerability due to improper sanitization of user-supplied input to the 'mosConfig_absolute_path' parameter before using it in the index.php script to include PHP code. Provided 'RG_EMULATION' is not defined in the configuration file (as would typically occur when upgrading from an older version) and the PHP 'register_globals' setting is disabled, an unauthenticated, remote attacker can exploit this issue to disclose arbitrary files or execute arbitrary PHP code on the remote host, subject to the privileges of the web server user ID.

Solution

Upgrade to Joomla! version 1.0.15 or later. Alternatively, edit the application's configuration.php file to disable 'RG_EMULATION'.
