Summary

Nagios Log Server versions prior to 2026R1.0.1 contain an authenticated command injection flaw (CVE-2025-34322) in the experimental 'Natural Language Queries' feature. User-controlled settings, including model selection and connection parameters, are concatenated into a shell command run through shell_exec() without proper input handling or argument sanitation. An authenticated user with access to the 'Global Settings' page can inject extra shell commands, gaining arbitrary command execution as 'www-data' and compromising the Log Server host.
