Loading vulnerability…
A misconfiguration in the web management console of CheckMK Raw Edition (versions 1.5.0 to 1.6.0) allows the default-installed Dokuwiki web-app to accept embedded PHP code. This enables remote code execution if an attacker gains access to the web management interface, either through valid credentials or by hijacking an administrator session.

This repository contains a proof-of-concept exploit for multiple vulnerabilities in CheckMK, primarily targeting CVE-2021-40904 (RCE via DokuWiki misconfiguration), but also referencing CVE-2021-36563 (XSS) and CVE-2021-40905 (RCE via .mkp upload). The exploit is provided as a Python script (within 'exploit.txt') that automates the attack chain: it logs into the CheckMK web interface, leverages XSS to steal the 'Secret Automation' token, and then either injects PHP code into the embedded DokuWiki application or uploads a malicious extension package to achieve remote code execution. The README.md provides context, affected versions, and references. The exploit requires valid credentials and access to the web interface. The endpoints targeted are the login page, DokuWiki, and the extension upload handler. The code is a functional PoC and not weaponized, but demonstrates the full attack chain for the vulnerabilities described.
