Description

TYPO3 is an open source web content management system. Prior to versions 9.5.34 ELTS, 10.4.29, and 11.5.11, Admin Tool sessions initiated via the TYPO3 backend user interface had not been revoked even if the corresponding user account was degraded to lower permissions or disabled completely. This way, sessions in the admin tool theoretically could have been prolonged without any limit. TYPO3 versions 9.5.34 ELTS, 10.4.29, and 11.5.11 contain a fix for the problem.

Technical Analysis

CVE-2022-31050 is a vulnerability identified in TYPO3, an open-source web content management system widely used for building and managing websites. The issue pertains to insufficient session expiration (CWE-613) in the TYPO3 backend Admin Tool. Specifically, in TYPO3 versions prior to 9.5.34 ELTS, 10.4.29, and 11.5.11, sessions initiated via the backend user interface for administrative users were not revoked or invalidated when the corresponding user account's permissions were downgraded or the account was disabled. This flaw allows active admin sessions to persist indefinitely, even if the user’s privileges have been reduced or the account has been disabled, effectively prolonging session validity without any time or state-based limit. This behavior can lead to unauthorized access if an attacker or a malicious insider retains an active session token after privilege revocation or account deactivation. The vulnerability affects TYPO3 versions from 9.0.0 up to but not including the fixed versions 9.5.34 ELTS, 10.4.29, and 11.5.11. The issue does not require user interaction or complex exploitation techniques; it arises from the system's failure to properly expire or revoke sessions upon account status changes. While no known exploits have been reported in the wild, the vulnerability presents a risk of unauthorized administrative access and potential misuse of backend controls. TYPO3 has addressed this issue in the specified patched versions by ensuring that sessions are invalidated appropriately when user permissions change or accounts are disabled, thus enforcing proper session lifecycle management and reducing the risk of session hijacking or privilege abuse.

Potential Impact

For European organizations using TYPO3 for their web content management, this vulnerability poses a significant risk to the confidentiality, integrity, and availability of their web infrastructure. Persistent admin sessions that are not revoked can be exploited by attackers or malicious insiders to maintain unauthorized access to backend administrative functions, even after account deactivation or privilege reduction. This could lead to unauthorized content modifications, data leakage, insertion of malicious code, or disruption of services. Given TYPO3’s popularity among public sector institutions, educational entities, and medium to large enterprises in Europe, the risk is amplified in environments where strict access control and session management are critical. The vulnerability could also facilitate lateral movement within networks if attackers leverage persistent sessions to escalate privileges or access sensitive internal systems. Although no active exploits are known, the ease of exploitation and the potential for long-term unauthorized access make this a medium-severity threat that requires prompt attention to prevent compromise.

Mitigation Recommendations

European organizations should immediately verify their TYPO3 installations and identify if they are running affected versions (>= 9.0.0 and < 9.5.34 ELTS, >= 10.0.0 and < 10.4.29, >= 11.0.0 and < 11.5.11). The primary mitigation is to upgrade TYPO3 to the fixed versions 9.5.34 ELTS, 10.4.29, or 11.5.11 or later. In addition to patching, organizations should implement the following specific measures: 1) Enforce strict session timeout policies and ensure sessions are invalidated upon user logout, permission changes, or account deactivation. 2) Conduct regular audits of active sessions in the TYPO3 backend to detect and terminate any lingering sessions associated with disabled or downgraded accounts. 3) Implement multi-factor authentication (MFA) for backend access to reduce the risk of session hijacking. 4) Monitor backend access logs for unusual or prolonged session activity that may indicate exploitation of this vulnerability. 5) Educate administrators on promptly revoking access and terminating sessions when user roles change. 6) Consider deploying web application firewalls (WAFs) with custom rules to detect anomalous session behavior related to TYPO3 backend access. These targeted actions, combined with patching, will reduce the risk of exploitation and improve overall session security.
