Information Disclosure in typo3/cms-install tool

Low severity GitHub Reviewed Published Nov 14, 2023 in TYPO3/typo3 • Updated Nov 14, 2023

Package

composer typo3/cms-install (Composer)

Affected versions

>= 12.2.0, < 12.4.8

Patched versions

12.4.8

Description

CVSS: CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:N/A:N/E:F/RL:O/RC:C (3.5)

Problem

The login screen of the standalone install tool discloses the full path of the transient data directory (e.g. /var/www/html/var/transient/). This applies to composer-based scenarios only - “classic” non-composer installations are not affected.

Solution

Update to TYPO3 version 12.4.8 that fixes 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.
