Description

Problem

The backend user management interface allows password changes without requiring the current password. When an administrator updates their own account or modifies other user accounts via the admin interface, the current password is not requested for verification.

This behavior may lower the protection against unauthorized access in scenarios where an admin session is hijacked or left unattended, as it enables password changes without additional authentication.

Solution

Update to TYPO3 versions 9.5.51 ELTS, 10.4.50 ELTS, 11.5.44 ELTS, 12.4.31 LTS, 13.4.12 LTS that fix the problem described.

Note

In these versions, administrators are required to verify their identity through step-up authentication (also known as sudo mode) when changing backend user passwords.

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.
