Synopsis

The remote web server contains a CGI application that is affected by multiple vulnerabilities.

Description

According to its version number, the instance of TWiki running on the remote host is affected by multiple security vulnerabilities :

- 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.
(CVE-2012-6329)

- The '%MAKETEXT{}%' variable fails to properly sanitize user-supplied input, which can lead to a denial of service) condition if an overly large value is passed to the variable. (CVE-2012-6330)
