Vulnerability Information

Severity: High
Vulnerability Published: 2012-12-12
Patch Published: 2012-12-16
CVE [?]: CVE-2012-6329, CVE-2012-6330
CPE [?]: cpe:/a:twiki:twiki

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)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Upgrade to TWiki version 5.1.3 or later. Alternatively, apply the hotfix referenced in the vendor advisory.

Public Exploits

Target Network Port(s): 80
Target Asset(s): Services/www
Exploit Available: True (Metasploit Framework, Exploit-DB, D2 Elliot)
