NOTE: as of 20090917, this disclosure has no actionable information. However, because the VulnDisco Pack author is a reliable researcher, the issue is being assigned a CVE identifier for tracking purposes.

The web interface on the Linksys WRT54g router with firmware 1.00.9 does not require credentials when invoking scripts, which allows remote attackers to perform arbitrary administrative actions via a direct request to (1) Advanced.tri, (2) AdvRoute.tri, (3) Basic.tri, (4) ctlog.tri, (5) ddns.tri, (6) dmz.tri, (7) factdefa.tri, (8) filter.tri, (9) fw.tri, (10) manage.tri, (11) ping.tri, (12) PortRange.tri, (13) ptrigger.tri, (14) qos.tri, (15) rstatus.tri, (16) tracert.tri, (17) vpn.tri, (18) Wan ... The web interface on the Linksys WRT54g router with firmware 1.00.9 does not require credentials when invoking scripts, which allows remote attackers to perform arbitrary administrative actions via a direct request to (1) Advanced.tri, (2) AdvRoute.tri, (3) Basic.tri, (4) ctlog.tri, (5) ddns.tri, (6) dmz.tri, (7) factdefa.tri, (8) filter.tri, (9) fw.tri, (10) manage.tri, (11) ping.tri, (12) PortRange.tri, (13) ptrigger.tri, (14) qos.tri, (15) rstatus.tri, (16) tracert.tri, (17) vpn.tri, (18) WanMac.tri, (19) WBasic.tri, or (20) WFilter.tri.
