A security bypass flaw in a popular wireless broadband router shipped by Cisco’s Linksys unit could give malicious hackers administrative access to vulnerable devices, researchers warned on Wednesday.

Independent technology consultant Alan W. Rateliff discovered the flaw during a client installation of a Linksys WRT54G Wireless-G Broadband Router. After reporting the vulnerability to Linksys, Rateliff posted a warning on a public mailing list that even if the remote administration function is turned off, the router provides the administration Web page to ports 80 and 443 on the WAN.
