Loading vulnerability…
Zenitel AlphaCom XE Audio Server (AlphaWeb XE) through version 11.2.3.10 contains an unrestricted file upload vulnerability in the Custom Scripts section at php/index.php. The application does not validate the content or extension of uploaded files, allowing attackers to upload arbitrary files, including PHP scripts, which are then accessible and executable under the /cmd directory.

This repository contains a working exploit for CVE-2021-40845, targeting Zenitel AlphaWeb XE (AlphaCom XE Audio Server) through version 11.2.3.10. The exploit is implemented in Python and automates the process of authenticating to the web interface (using default credentials for 'admin' and 'scripter'), uploading a malicious PHP webshell via an insecure file upload endpoint, and then executing arbitrary system commands through the webshell. The main exploit file is 'CVE-2021-40845.py', which takes a target URL and a command to execute as arguments. The README.md provides detailed vulnerability information, exploitation steps, and references. The exploit leverages three main HTTP endpoints: '/php/index.php' for login, '/php/script_uploads.php' for file upload, and '/cmd/poc.php?cmd=<command>' for command execution. The payload is a simple PHP webshell that executes commands passed via the 'cmd' parameter. The exploit is operational and provides remote code execution capabilities to an authenticated attacker.
