DescriptionCVE.org

linuxfabrik-lib provides Python modules for database access, caching, shell execution, and API integrations. Prior to version 4.2.0, db_sqlite.py created SQLite databases at predictable paths in the shared /tmp directory and followed attacker-created symbolic links at those paths. An attacker who controls a local monitoring account can create a symlink such as /tmp/linuxfabrik-monitoring-plugins-docker-stats.db and then trigger a sudo-authorized plugin, causing the root process to create or modify the symlink target. The primitive can overwrite arbitrary paths, cause denial of service, or manipulate an existing SQLite database through a crafted rollback journal or write-ahead log. The Monitoring Plugins integration also moved plugin caches through lib.db_sqlite.get_db_path() so they use the secured per-user directory. This issue is fixed in version 4.2.0.
