Title source: llm
STIX 2.1

Exploitation Summary

EIP tracks 1 public exploit for CVE-2025-34322. PoCs published by mcorybillington.

AI-analyzed exploit summary This repository contains a working proof-of-concept exploit for CVE-2025-34322, an authenticated command injection vulnerability in Nagios Log Server, and a privilege escalation exploit for CVE-2025-34323. The PoC demonstrates command injection via the `self_host_ip_address` parameter and leverages sudo misconfigurations to escalate privileges to root.

Description

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.
