Loading vulnerability…
A path traversal vulnerability exists in Joomla! versions 3.0.0 through 3.9.24 within the com_media component. The vulnerability allows attackers to specify paths that are not intended for image uploads, potentially enabling access to arbitrary files or directories on the server.

This repository contains a Python proof-of-concept exploit for two related Joomla vulnerabilities: CVE-2021-23132 and CVE-2020-24597. Both affect the com_media component in Joomla core versions up to 3.9.24, allowing an attacker with admin (but not superadmin) privileges to escalate to superadmin and achieve remote code execution (RCE). The repository consists of a README.md, which provides usage instructions and context, and the main exploit script, cve-2021-23132.py. The script automates the exploitation process: it logs in as an admin, manipulates media options to enable directory traversal, creates a superadmin user, and then triggers RCE by sending crafted requests to a vulnerable endpoint (such as /templates/protostar/error.php?cmd=...). The exploit requires valid admin credentials and network access to the target Joomla instance. The attack vector is network-based, and the exploit is operational, providing a working payload for privilege escalation and RCE. The script is written in Python and requires the lxml library. No hardcoded IPs or domains are present, but example endpoints are provided in the documentation.
