10.0

CVSS v3.1

Official Description

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. NOTE: the Security.tri vector is already covered by CVE-2006-5202.

Technical Analysis

CVE-2008-1247 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.

Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.

A proof-of-concept (PoC) exploit exists for CVE-2008-1247. While not yet confirmed in active campaigns, the availability of PoC code increases exploitation risk substantially.
