A vulnerability was found in TYPO3 up to 4.6.1 (Content Management System). It has been declared as critical. Affected by this vulnerability is some unknown functionality of the file AbstractController.php. The manipulation of the argument BACK_PATH with an unknown input leads to a code injection vulnerability. The CWE definition for the vulnerability is CWE-94. The product constructs all or part of a code segment using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the syntax or behavior of the intended code segment. As an impact it is known to affect confidentiality, integrity, and availability. The summary by CVE is:

PHP remote file inclusion vulnerability in Classes/Controller/AbstractController.php in the workspaces system extension in TYPO3 4.5.x before 4.5.9, 4.6.x before 4.6.2, and development versions of 4.7 allows remote attackers to execute arbitrary PHP code via a URL in the BACK_PATH parameter.

The weakness was shared 12/16/2011 by MaXe (Website). The advisory is shared at typo3.org. This vulnerability is known as CVE-2011-4614 since 11/29/2011. The attack can be launched remotely. The exploitation doesn't need any form of authentication. Technical details and also a public exploit are known. MITRE ATT&CK project uses the attack technique T1059 for this issue.

A public exploit has been developed by MaXe and been published 3 weeks after the advisory. It is possible to download the exploit at exploit-db.com. It is declared as highly functional. We expect the 0-day to have been worth approximately $5k-$25k. By approaching the search of inurl:AbstractController.php it is possible to find vulnerable targets with Google Hacking. The vulnerability scanner Nessus provides a plugin with the ID 57394 (TYPO3 'AbstractController.php' 'BACK_PATH' Parameter Remote File Inclusion), which helps to determine the existence of the flaw in a target environment. It is assigned to the family CGI abuses.

Upgrading to version 4.6.2 eliminates this vulnerability. A possible mitigation has been published immediately after the disclosure of the vulnerability.
