Package

composer typo3/cms-core (Composer)

Affected versions

9.0.0-9.5.34, 10.0.0-10.4.28, 11.0.0-11.5.10

Patched versions

Description

Meta

  • CVSS: CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:L/A:L/E:F/RL:O/RC:C (5.6)

Problem

Admin Tool sessions initiated via the TYPO3 backend user interface have not been revoked even if the corresponding user account was degraded to lower permissions or disabled completely.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.

Solution

Update to TYPO3 versions 9.5.35 ELTS, 10.4.29, 11.5.11 that fix the problem described above.

CVSS v3 base metrics

Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.
