DESCRIPTION:
Gabriel Lima has reported a vulnerability in Linksys WRT54GC, which
can be exploited by malicious people to bypass certain security
restrictions.

The vulnerability is caused due to the router allowing unrestricted
access to the administration.cgi web interface script. This can be
exploited to change the administrator's password by sending a
specially crafted HTTP request to the affected script.

The vulnerability is reported in firmware version 1.05.7. Other
versions may also be affected.

SOLUTION:
Restrict internal network access to trusted users only.

PROVIDED AND/OR DISCOVERED BY:
