CVE-2021-26814 is a vulnerability in the Wazuh API (versions 4.0.0 to 4.0.3) that allows authenticated users to execute arbitrary code with administrative privileges. The flaw exists due to incomplete input validation in the /manager/files API endpoint, enabling attackers to inject arbitrary code into the API service script.

This repository contains a Python proof-of-concept exploit for CVE-2021-26814, targeting Wazuh Manager versions 4.0.0 to 4.0.3 via its API service. The main file, PoC.py, is a command-line tool that requires valid Wazuh API credentials and both attacker and target network details. The exploit works by authenticating to the API, backing up the original 'wazuh-apid.py' script, escalating API privileges to run as root, and then overwriting the API script with a Python payload that opens a reverse shell to the attacker's machine using netcat. The exploit then restarts the API service to trigger execution of the payload. The repository also includes a README with usage instructions and a license file. The exploit is operational and provides a working reverse shell if the target is vulnerable and properly configured.
