CVE-2023-40931 is an SQL injection vulnerability affecting Nagios XI from version 5.11.0 through 5.11.1. The flaw is present in the administrative endpoint banner_message-ajaxhelper.php, where the ID parameter in a POST request is not properly sanitized before being incorporated into SQL queries. An authenticated attacker can exploit this weakness to execute arbitrary SQL commands against the application's backend database. Depending on database permissions and application context, exploitation can expose or alter stored application data and may facilitate further compromise of the Nagios XI instance.

This repository provides a Proof of Concept (PoC) exploit for CVE-2023-40931, targeting Nagios XI. The main exploit script (exploit.py) authenticates to the Nagios XI web interface, obtains an authentication token, and tests for SQL injection in the 'banner_message-ajaxhelper.php' endpoint. It can optionally invoke sqlmap to automate database extraction. The admin-exploit.py script attempts to create a new admin user via the Nagios XI API and execute a reverse shell, though the reverse shell functionality is noted as unreliable. The repository includes detailed usage instructions and example payloads in the readme.md. The exploit demonstrates the ability to exploit SQL injection vulnerabilities and, if successful, could allow an attacker to extract sensitive data or gain administrative access. The code is written in Python and is intended for educational and authorized testing purposes only.
