A vulnerability was found in TYPO3 up to 6.2 (Content Management System). It has been rated as critical. This issue affects an unknown part of the component Content Editing Wizard. The manipulation with an unknown input leads to a cryptographic issues vulnerability (Unserialize). Using CWE to declare the problem leads to CWE-310. Impacted is confidentiality, and integrity. The summary by CVE is:

The Content Editing Wizards component in TYPO3 4.5.0 through 4.5.31, 4.7.0 through 4.7.16, 6.0.0 through 6.0.11, and 6.1.0 through 6.1.6 allows remote authenticated backend users to unserialize arbitrary PHP objects, delete arbitrary files, and possibly have other unspecified impacts via an unspecified parameter, related to a "missing signature."

The weakness was presented 12/10/2013 by Rupert Germann as TYPO3-CORE-SA-2013-004: Multiple Vulnerabilities in TYPO3 CMS as confirmed advisory (Website). It is possible to read the advisory at typo3.org. The identification of this vulnerability is CVE-2013-7075 since 12/11/2013. The attack may be initiated remotely. A simple authentication is necessary for exploitation. The technical details are unknown and an exploit is not publicly available. The attack technique deployed by this issue is T1600 according to MITRE ATT&CK. The advisory points out:

Due to a missing signature for an input parameter an attacker could unserialize arbitrary objects within TYPO3. We are aware of a working exploit which can be used to delete arbitrary files which are writable for the PHP server process. A valid backend user login or a successful Cross-Site Request Forgery attack are required to exploit this vulnerability.
