CyberRota Analysis
AI-GeneratedThe Linuxfabrik Monitoring Plugins prior to version 7.0.0 are vulnerable due to improper handling of file paths in the check-plugins/logfile/logfile component, allowing an attacker with monitoring account access to read sensitive files, such as /etc/shadow, as root. This vulnerability can lead to unauthorized information disclosure, making it critical for organizations using Icinga or Nagios monitoring systems to prioritize upgrading to version 7.0.0 to mitigate potential exploitation.

Original NVD Description
Linuxfabrik Monitoring Plugins provides monitoring plugins for Icinga, Nagios, and related systems. Prior to version 7.0.0, check-plugins/logfile/logfile accepted a free-form --filename path and opened it as root when invoked through the shipped nagios or icinga sudoers allowlist, without confining the resolved path to /var/log. An attacker who controls the monitoring account can select a root-readable file such as /etc/shadow and use --warning-regex . while leaving SUPPRESS_OUTPUT false, causing each nonempty line to be collected in warn_matches and returned through lib.base.oao(). The vulnerable flow passes the expanded scan_path directly to open(), and neither real-path containment nor an allowlist protects the sink. The same fix also confines mysql-logfile and openvpn-client-list paths, allows only documented log roots, and resolves symlinks and parent-directory traversal before checking containment. This issue is fixed in version 7.0.0.
