CVE-2007-5383 Information

Description

The Thomson/Alcatel SpeedTouch 7G router as used for the BT Home Hub 6.2.6.B and earlier allows remote attackers on an intranet to bypass authentication and gain administrative access via vectors including a ‘/’ (slash) character at the end of the PATH_INFO to cgi/b aka \double-slash auth bypass.\ NOTE: remote attackers outside the intranet can exploit this by leveraging a separate CSRF vulnerability. NOTE: SpeedTouch 780 might also be affected by some of these issues.
