Unauthenticated Root RCE in Xspeeder SXZOS vLogin.py
CVE-2025-54322 is a critical unauthenticated remote code execution vulnerability in Xspeeder SXZOS through 2025-12-26. The flaw is in the web interface, specifically the vLogin.py script, where attacker-controlled input is insufficiently validated before being base64-decoded and dynamically evaluated as Python code. Available reporting indicates the chkid parameter is the primary injection vector, with title and oIP also used in the vulnerable request flow. Multiple sources describe the root cause as unsafe use of eval() on base64-decoded user input in Django-based authentication logic. A remote attacker can send a crafted HTTP GET request to trigger execution of arbitrary Python code on the target device.

This repository provides a professional proof-of-concept exploit for CVE-2025-54322, a critical pre-authentication remote code execution vulnerability in XSpeeder SXZOS firmware (SD-WAN/Edge Routers). The exploit leverages an unsafe eval() of a base64-decoded 'chkid' parameter in the vLogin.py component, allowing arbitrary Python code execution as root. The main exploit script (cve-2025-54322-exploit.py) is written in Python 3 and offers an interactive pseudo-shell with directory tracking, as well as one-click reverse shell payloads (bash and python) for remote access. The exploit is operational and user-friendly, with advanced output cleaning for Django debug pages and session warm-up via the /webInfos/ endpoint. The repository includes detailed English and Chinese documentation (README.md, README_CN.md) and is intended for authorized security testing. No hardcoded IPs or credentials are present; the user supplies the target URL and reverse shell listener details at runtime.
