Linksys WRT54G 3.01.03, 3.03.6, 4.00.7, and possibly other versions before 4.20.7, does not verify user authentication until after an HTTP POST request has been processed, which allows remote attackers to (1) modify configuration using restore.cgi or (2) upload new firmware using upgrade.cgi.

Security readout for executives and security teams

This flaw affects old Linksys WRT54G router firmware. The router could process sensitive web-management requests before confirming the user was authenticated, allowing remote attackers to change configuration or upload firmware if they can reach the management interface. Exposure is likely limited to Linksys WRT54G routers running the listed legacy firmware or possibly other builds before 4.20.7. Business risk is highest where router administration is reachable from untrusted networks. Treat this as a high-priority legacy network device issue. The main decision is whether affected routers still exist in production and whether their management interfaces are reachable by attackers. Mitigation focus: Inventory Linksys WRT54G routers and record exact firmware versions.; Check Linksys or vendor guidance for corrected firmware around version 4.20.7.; Disable remote administration from untrusted networks where possible..
