Description

VenturoLab Team has reported a vulnerability in Linksys WRT54GC, which can be exploited by malicious people to conduct cross-site request forgery attacks.

The diagnostics.cgi script allows users to perform certain actions via HTTP requests without performing any validity checks to verify the requests. This can be exploited to e.g. inject arbitrary script code or cause a DoS via the "ping_address" and "raceroute_address" parameters.

The vulnerability is reported in firmware version 1.01.5 and 1.00.7. Other versions may also be affected.
