Loading vulnerability…
TP-Link TL-WR902AC devices through firmware version V3 0.9.1 inadequately verify firmware-update signatures. A remote authenticated attacker can upload a crafted firmware update to execute arbitrary code or cause a denial of service.

This repository demonstrates a practical exploit for CVE-2022-48194, targeting the TP-Link TL-WR902AC router (firmware V3 0.9.1 Build 220329 and earlier). The exploit is implemented in a single Python script (exploits/CVE-2022-48194.py) that automates the process of building and uploading a malicious firmware image. The script downloads the official firmware, unpacks it, injects a custom init script that launches a persistent netcat listener on TCP port 3030 (providing a root shell), repacks the firmware, and uploads it to the router via its web interface. The exploit requires authenticated access to the router's admin interface. Upon successful exploitation, the attacker gains persistent root shell access to the device. The repository also includes a README.md with detailed background, disclosure timeline, and references. The exploit is operational and demonstrates a real-world attack chain against vulnerable TP-Link routers.
