CVE-2020-8958 is an unauthenticated remote OS command injection vulnerability affecting Guangzhou 1GE ONU V2801RW firmware versions 1.9.1-181203 through 2.9.0-181024 and V2804RGW firmware versions 1.9.1-181203 through 2.9.0-181024. The flaw is in the web management interface, specifically the boaform/admin/formPing handler, where the Dest IP Address field is not properly sanitized before being passed to an underlying system shell. An attacker can supply shell metacharacters in that parameter to append arbitrary commands to the ping operation, resulting in execution of attacker-controlled OS commands on the device.

This repository contains a Python exploit script (CVE-2020-8958.py) and a README.md for CVE-2020-8958, an authenticated remote code execution vulnerability affecting NetLink routers (notably model HG323) running the 'boa' web server. The exploit targets the '/boaform/admin/formPing' endpoint, which is vulnerable to OS command injection via the 'target_addr' POST parameter. The script first attempts to authenticate (default credentials: admin:admin) via '/boaform/admin/formLogin', then injects commands to '/boaform/admin/formPing'. Upon successful exploitation, the attacker can execute arbitrary shell commands on the router. The repository is structured simply, with the main exploit logic in a single Python file and usage/documentation in the README. The exploit requires valid credentials and network access to the router's web interface.
