CyberRota Analysis
AI-GeneratedThe vulnerability affects the linuxfabrik-lib Python modules used for database access in Linux and Docker environments, specifically prior to version 4.2.0. An attacker with local access can exploit predictable SQLite database paths in the shared /tmp directory to create symlinks, potentially allowing them to overwrite arbitrary files, cause denial of service, or manipulate databases. Organizations using affected versions should prioritize upgrading to version 4.2.0 to mitigate these risks.

Original NVD Description
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.
