CVE-2026-67433 Linuxfabrik monitoring-plugins: Symlink following in logfile legacy database migration

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...

Name of the Vulnerable Software and Affected Versions linuxfabrik-lib versions prior to 6.0.0 Description The lib.url.fetch function follows cross-origin redirects while forwarding caller-supplied credential headers, excluding Authorization and Cookie. This behavior allows a malicious server...

Linuxfabrik Monitoring Plugins allow insecure creation of SQLite databases

SummaryThe SQLite databases are created at predictable static paths in /tmp. Any user can therefore create a symlink at these paths in /tmp pointing to arbitrary files. The monitoring scripts then follows these symlinks and then creates their database at the symlink target.This becomes really...

PYSEC-2026-2595 Linuxfabrik Monitoring Plugins: Sudoers may be able to obtain privilege escalation via /usr/bin/apt-get arguments

Summary In the Debian.sudoers file, apt-get is allowed for the nagios user. The full command including the arguments are not enforced and can therefore be choosen arbitrarily. This allows to easily get a root shell as the nagios user: PoC By choosing a particular argument, you can get as a nagios...

Linuxfabrik Monitoring Plugins have local privilege escalation using embedded command

Summary When a check plugin places user provided input inside a command which is passed to shellexec, an attacker can abuse this to run arbitrary commands. This is mainly dangerous for plugins which are listed in the sudoers file, because this allows an attacker controlling the nagios user to get...

Command Injection

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 Command Injection via the shellexec function. An attacker can execute arbitrary commands with elevated...
