TYPO3 Image Processing susceptible to Code Execution

High severity GitHub Reviewed Published May 24, 2022 to the GitHub Advisory Database • Updated Feb 29, 2024

Package

composer typo3/cms (Composer)

Affected versions

>= 8.0.0, < 8.7.25
>= 9.0.0, < 9.5.6

Patched versions

8.7.25
9.5.6
composer typo3/cms-core (Composer)
>= 8.0.0, < 8.7.25
>= 9.0.0, < 9.5.6
8.7.25
9.5.6

Description

TYPO3 8.x before 8.7.25 and 9.x before 9.5.6 is susceptible to remote code execution because it does not properly configure the applications used for image processing, as demonstrated by ImageMagick or GraphicsMagick.
For a successful exploit, the GhostScript binary gs must be available on the server system.

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.
