TYPO3-EXT-SA-2012-012: Several Vulnerabilities in extension Formhandler
(formhandler)

October 25, 2012


Category: TYPO3 Extension
Author: Georg Ringer
Keywords: TYPO3, security, TYPO3-EXT-SA-2012-012, extension, formhandler

It has been discovered that the extension Formhandler (formhandler) is
vulnerable to SQL-Injection and Cross-Site Scripting.


Component Type: Third party extension. This extension is not a part of
the TYPO3 default installation.

Affected Versions: Version 1.4.0 and below

Vulnerability Types: SQL Injection, Cross-Site Scripting


Severity: Medium

Suggested CVSS v2.0: AV:N/AC:L/Au:S/C:P/I:C/A:P/E:P/RL:O/RC:C (What's that?)

Release Date: 25.10.2012



Problem Description: Failing to properly sanitize user input,
formhandler is susceptible to SQL Injection. An attacker could delete
arbitrary database tables. Editors rights with permission to use the
formhandler backend module are required for this to work.

Failing to encode user data for the HTML output, formhandler is
susceptible to Cross Site Scripting. No authentication is required to
exploit this vulnerability.

Solution: An updated version 1.4.1 is available from the TYPO3
extension manager and at
typo3.org/extensions/repository/view/formhandler/1.4.1/.

Credits: Thanks to Sven Krewitt who discovered and reported this issue.


General advice: Follow the recommendations that are given in the TYPO3
Security Cookbook. Please subscribe to the typo3-announce mailing list
