Linuxfabrik monitoring-plugins: Symlink following in logfile legacy database migration

Published Jul 29, 2026 · Updated Jul 30, 2026 · Assigned by GitHub_M

Description

Linuxfabrik monitoring-plugins provides Python monitoring plugins for Icinga, Nagios, and related monitoring systems. In version 6.0.0, the logfile check legacy database migration moved a predictable path from /tmp with os.rename() and allowed a local user controlling the plugin account to place a symlink that would be followed by sqlite3.connect() during a root-run check.
