MODx 'ucfg' Parameter Arbitrary File Access

medium Nessus Plugin ID 51974

Language:

Synopsis

It may be possible to download arbitrary files from the remote system.

Description

The installed version of MODx allows access to arbitrary files because it fails to perform sufficient validation on 'ucfg' parameter in 'assets/snippets/ajaxSearch/ajaxSearchPopup.php'.

By supplying directory traversal strings such as '..%2F' in a specially crafted AjaxSearch 'POST' request, it is possible for a remote, unauthenticated attacker to read arbitrary files from the remote system, subject to the privileges under which the web server operates.

Although Nessus has not checked for them, the installed version is also likely to be affected by several other vulnerabilities, including cross-site scripting and SQL injection.

Solution

Upgrade to MODx 1.0.5 or later.
