CVE-2023-41044 is a partial path traversal vulnerability in Graylog's Support Bundle feature. The issue is caused by insufficient validation of user-supplied input in an HTTP API resource handling support bundle file operations. An attacker with valid Graylog Admin role credentials can abuse the affected API endpoints to access files outside the intended support bundle directory, specifically in sibling directories whose names begin with the support bundle directory path. In default DEB/RPM installations, Graylog's data directory is /var/lib/graylog-server and the Support Bundle directory is <data_dir>/support-bundle, allowing access to files in directories such as /var/lib/graylog-server/support-bundle-test or /var/lib/graylog-server/support-bundlesdirectory. In Graylog Docker images, the default data_dir is /usr/share/graylog/data, with the same support-bundle subdirectory pattern. The vulnerable functionality is exposed through the HTTP API endpoints GET /api/system/debug/support/bundle/download/{filename} and DELETE /api/system/debug/support/bundle/{filename}.
