The vulnerability identified as CVE-2014-6292 affects the femanager extension version 1.0.8 and earlier in the TYPO3 content management system, representing a critical authorization flaw that enables malicious frontend users to manipulate or delete records belonging to other users. This issue stems from inadequate access control mechanisms within the extension's user management functionality, creating a privilege escalation scenario where unauthorized individuals can exploit the system's user data handling capabilities.
The technical flaw manifests through unspecified vectors that allow attackers to bypass normal user permissions and access records they should not be authorized to modify or delete. The femanager extension, designed to provide frontend user management capabilities, fails to implement proper user isolation mechanisms, enabling cross-user data manipulation. This vulnerability specifically impacts the extension's handling of user records within TYPO3's frontend environment, where proper authentication and authorization checks are insufficiently enforced.
From an operational impact perspective, this vulnerability creates significant security risks for TYPO3 installations using the affected femanager extension. Attackers can potentially access sensitive user information, modify user profiles, delete user accounts, or manipulate user-related data within the system. The implications extend beyond simple data manipulation to include potential account takeovers, data integrity violations, and unauthorized access to user-specific content or services. Organizations using TYPO3 with this extension face risks of user data compromise and potential system-wide security degradation.
The vulnerability aligns with CWE-284 (Improper Access Control) and represents a classic example of insufficient authorization checks in web applications. It also maps to ATT&CK technique T1078 (Valid Accounts) as attackers can leverage legitimate user accounts to perform unauthorized actions. The flaw demonstrates poor input validation and access control implementation, where the extension fails to verify that the requesting user has proper authorization to modify or delete records belonging to other users.
Mitigation strategies should include immediate upgrade to femanager version 1.0.9 or later, which contains the necessary access control fixes. Organizations should also implement additional monitoring of user activity within frontend management systems, review and strengthen access control policies, and consider implementing additional security layers such as role-based access controls and enhanced logging mechanisms. System administrators should conduct comprehensive security assessments of all TYPO3 extensions to identify similar vulnerabilities and ensure proper authorization enforcement throughout the application stack.
