CWE ID 22

Summary

CVE-2023-41044 is a partial path traversal vulnerability affecting Graylog's Support Bundle feature. With valid Admin role credentials, an attacker can download or delete files in sibling directories of the support bundle directory. The vulnerability arises due to incorrect user input validation in an HTTP API resource. By manipulating the file name in the API endpoints `GET /api/system/debug/support/bundle/download/{filename}` and `DELETE /api/system/debug/support/bundle/{filename}`, an attacker can traverse and access or delete files in various directories, including those starting with `/var/lib/graylog-server/support-bundle`. This issue is fixed in Graylog versions 5.1.3 and later. Users unable to upgrade should block the affected API endpoints using a reverse proxy server.
