DESCRIPTION:
Cristofaro Mune has reported a vulnerability in Linksys WAP54G, which
can be exploited by malicious people to compromise a vulnerable
device.

The vulnerability is caused due to the device containing the
undocumented "Debug_command_page.asp" and "debug.cgi" debug scripts.
This can be exploited to e.g. gain root access by accessing the debug
scripts using hard-coded credentials.

The vulnerability is reported in version 3.05.03 and 3.04.03.

Note: Reportedly, this only affects devices running a firmware
approved for EMEA (Europe, Middle East, and Africa). Thus, devices
sold in the USA or running US firmware versions are not affected.

SOLUTION:
Restrict access using a proxy or firewall.

PROVIDED AND/OR DISCOVERED BY:
