Detailsinfo

A vulnerability classified as critical has been found in Mattermost up to 9.11.7/10.2.2/10.3.2/10.4.1. Affected is an unknown code of the component Archive Import Handler. The manipulation with an unknown input leads to a path traversal vulnerability. CWE is classifying the issue as CWE-22. The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

Mattermost versions 10.4.x <= 10.4.1, 9.11.x <= 9.11.7, 10.3.x <= 10.3.2, 10.2.x <= 10.2.2 fail to properly validate board blocks when importing boards which allows an attacker could read any arbitrary file on the system via importing and exporting a specially crafted import archive in Boards.

The weakness was disclosed by visat. The advisory is available at mattermost.com. This vulnerability is traded as CVE-2025-25279 since 02/18/2025. The exploitability is told to be easy. It is possible to launch the attack remotely. The technical details are unknown and an exploit is not available. This vulnerability is assigned to T1006 by the MITRE ATT&CK project.

The vulnerability scanner Nessus provides a plugin with the ID 216937 (Mattermost Server 9.11.x < 9.11.8 / 10.2.x < 10.2.3 / 10.3.x < 10.3.3 / 10.4.x < 10.4.2 (MMSA-2025-00430)), which helps to determine the existence of the flaw in a target environment.
