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Admin Tool sessions initiated via the TYPO3 backend user interface have not been revoked even if the corresponding user account was degraded to lower permissions or disabled completely.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