TWiki < 5.1.4 MAKETEXT Variable Tilde Character Command Injection

Medium Nessus Plugin ID 64876

Synopsis

The remote web server hosts a CGI application that is affected by a command injection vulnerability.

Description

According to its version number, the instance of TWiki running on the remote host is affected by a command injection vulnerability. The '%MAKETEXT{}%' variable fails to properly sanitize user-supplied input. A remote attacker can exploit this issue to execute arbitrary shell commands on the remote host subject to the privileges of the web server user.

Note that only TWiki installs with localization enabled are affected.

Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Upgrade to TWiki version 5.1.4 or later. Alternatively, apply the hotfix referenced in the vendor advisory.
