HIGH 8.6

DescriptionCVE.org

Nagios Log Server versions prior to 2026R1.0.1 contain an authenticated command injection vulnerability in the experimental 'Natural Language Queries' feature. When this feature is configured, certain user-controlled settings-including model selection and connection parameters-are read from the global configuration and concatenated into a shell command that is executed via shell_exec() without proper input handling or command-line argument sanitation. An authenticated user with access to the 'Global Settings' page can supply crafted values in these fields to inject additional shell commands, resulting in arbitrary command execution as the 'www-data' user and compromise of the Log Server host.

AnalysisAI

Nagios Log Server versions prior to 2026R1.0.1 contain an authenticated command injection vulnerability in the experimental 'Natural Language Queries' feature. Rated high severity (CVSS 8.6), this vulnerability is remotely exploitable, low attack complexity. No vendor patch available.

Technical ContextAI

This vulnerability is classified as OS Command Injection (CWE-78), which allows attackers to execute arbitrary operating system commands on the host. Nagios Log Server versions prior to 2026R1.0.1 contain an authenticated command injection vulnerability in the experimental 'Natural Language Queries' feature. When this feature is configured, certain user-controlled settings-including model selection and connection parameters-are read from the global configuration and concatenated into a shell command that is executed via shell_exec() without proper input handling or command-line argument sanitation. An authenticated user with access to the 'Global Settings' page can supply crafted values in these fields to inject additional shell commands, resulting in arbitrary command execution as the 'www-data' user and compromise of the Log Server host. Affected products include: Nagios Log Server. Version information: prior to 2026.

RemediationAI

No vendor patch is available at time of analysis. Monitor vendor advisories for updates. Avoid passing user input to shell commands. Use language-specific APIs instead of shell execution. Apply strict input validation with allowlists.
