CVE-2026-30809Network attack vector

Authenticated command execution via WebServerModuleDebug blacklist bypass

Published Apr 13, 2026 · Updated Apr 13, 2026

OS command injection in Pandora FMS 777 through 800 allows remote authenticated users to execute commands through WebServerModuleDebug. The module applies an incomplete blacklist to attacker-controlled command input and then passes the filtered value to an operating-system command. A low-privileged account and network access to the web console are required; successful exploitation runs commands with the console process's privileges.
