BT : Security Vulnerabilities

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.

Multiple buffer overflows in the British Telecommunications Business Connect webhelper ActiveX control before 1.0.0.7 in btbconnectwebcontrol.dll allow remote attackers to execute arbitrary code via unspecified vectors.

cgi/b on the BT Home Hub router allows remote attackers to bypass authentication, and read or modify administrative settings or make arbitrary VoIP telephone calls, by placing a character at the end of the PATH_INFO, as demonstrated by (1) %5C (encoded backslash), (2) '%' (percent), and (3) '~' (tilde). NOTE: the '/' (slash) vector is already covered by CVE-2007-5383.

In BAOTA linux panel there exists a stored xss vulnerability attackers can use to obtain sensitive information via the log analysis feature.

The BT Voyager 2000 Wireless ADSL Router has a default public SNMP community name, which allows remote attackers to obtain sensitive information such as the password, which is stored in plaintext.

BT Voyager 2091 Wireless firmware 2.21.05.08m_A2pB018c1.d16d and earlier, and 3.01m and earlier, allow remote attackers to bypass the authentication process and gain sensitive information, such as configuration information via (1) /btvoyager_getconfig.sh, PPP credentials via (2) btvoyager_getpppcreds.sh, and decode configuration credentials via (3) btvoyager_decoder.c.

Multiple cross-site request forgery (CSRF) vulnerabilities in the Thomson/Alcatel SpeedTouch 7G router, as used for the BT Home Hub 6.2.6.B and earlier, allow remote attackers to perform actions as administrators via unspecified POST requests, as demonstrated by enabling an inbound remote-assistance HTTPS session on TCP port 51003. NOTE: an authentication bypass can be leveraged to exploit this in the absence of an existing administrative session. NOTE: SpeedTouch 780 might also be affected by some of these issues.

Multiple cross-site scripting (XSS) vulnerabilities in the Thomson/Alcatel SpeedTouch 7G router, as used for the BT Home Hub 6.2.6.B and earlier, allow remote attackers to inject arbitrary web script or HTML via unspecified vectors.
