Cockpit 2.13.5 and earlier is vulnerable to directory traversal via the Buckets component. This vulnerability allows authenticated attackers to write files to arbitrary locations within the uploads directory or overwrite assets with malicious versions.
AnalysisAI
Cockpit CMS versions 2.13.5 and earlier allow authenticated attackers to write files to arbitrary locations within the uploads directory or overwrite assets via directory traversal in the Buckets component. The vulnerability requires valid user authentication and does not impact confidentiality, but enables integrity compromise through malicious file placement or asset replacement. A proof-of-concept exists, though the SSVC framework rates automatable exploitation as unlikely, suggesting manual attack steps are required.
Technical ContextAI
The vulnerability is a classic directory traversal (path traversal) flaw classified under CWE-22, occurring in the Buckets component responsible for file upload management. Attackers can leverage path traversal sequences (such as '../' or similar Unicode/encoding variants) to escape the intended uploads directory sandbox and write files to arbitrary locations, including asset directories that serve public content. This is a file-handling vulnerability common in content management systems where input validation on file paths is insufficient before filesystem operations.
RemediationAI
Vendor-released patch: Cockpit CMS 2.14.0 or later. Upgrade immediately to v2.14.0 or newer, which includes explicit fixes for the Bucket path traversal vulnerability as documented in the GitHub release notes. If immediate upgrade is not feasible, restrict Bucket upload permissions to trusted users only and implement filesystem-level access controls to prevent writes outside the designated uploads directory. Additionally, apply web server configuration to block requests containing path traversal sequences (e.g., '../') in upload endpoints, though this is a defense-in-depth measure and not a substitute for patching. Note that v2.14.0 also hardens multiple other security aspects including session cookie handling and MongoLite query restrictions, making the upgrade beneficial beyond this single vulnerability.
