Overview
linuxfabrik-lib is a Python libraries used in various Linuxfabrik projects, including the 'Linuxfabrik Monitoring Plugins' project.
Affected versions of this package are vulnerable to Insecure Temporary File in the process that creates SQLite databases at predictable paths in /tmp. An attacker can overwrite or modify arbitrary files by creating symlinks at these paths, which are then followed by the monitoring scripts. This can result in unauthorized modification of files or denial of service by corrupting or replacing important files when the scripts are executed with elevated privileges. This is only exploitable if an attacker has already compromised the account used to execute the monitoring scripts and the system does not employ protections such as isolated temporary directories.
