Securing Network Management Systems: Nagios XI

Claroty Team82 discovered and privately disclosed 11 vulnerabilities in Nagios XI and associated wizards that—individually and when chained—allow credential theft, local privilege escalation, and post-authenticated remote code execution that can escalate to root; they produced a proof-of-concept showing a reverse shell as root and Nagios issued fixes in August. The report explains vulnerability details (CVE list), exploitation chains (notably a path traversal leading to webshell and a sudo-related LPE), impact considerations for network management systems, and mitigation recommendations (apply updates, monitor access, and limit trust).
