The Alcatel A30 device with a build fingerprint of TCL/5046G/MICKEY6US:7.0/NRD90M/J63:user/release-keys contains a hidden privilege escalation capability to achieve command execution as the root user. They have made modifications that allow a user with physical access to the device to obtain a root shell via ADB. Modifying the read-only properties by an app as the system user creates a UNIX domain socket named factory_test that will execute commands as the root user by processes that have privilege to access it (as per the SELinux rules that the vendor controls).

The UPnP IGD implementation on SpeedTouch 5x6 devices with firmware before 6.2.29 allows remote attackers to establish arbitrary port mappings by sending a UPnP AddPortMapping action in a SOAP request to the WAN interface, related to an "external forwarding" vulnerability.

Stack-based buffer overflow in the Agranet-Emweb embedded management web server in Alcatel OmniSwitch OS7000, OS6600, OS6800, OS6850, and OS9000 Series devices with AoS 5.1 before 5.1.6.463.R02, 5.4 before 5.4.1.429.R01, 6.1.3 before 6.1.3.965.R01, 6.1.5 before 6.1.5.595.R01, and 6.3 before 6.3.1.966.R01 allows remote attackers to execute arbitrary code via a long Session cookie.

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.

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 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.

Alcatel OmniSwitch 7000 and 7800 allows remote attackers to cause a denial of service (reboot) via certain network scans, as demonstrated using a Nessus port scan of ports 1 through 1024 with safe-checks disabled.

Alcatel OmniSwitch 7700/7800 switches running AOS 5.1.1 contains a back door telnet server that was intended for development but not removed before distribution, which allows remote attackers to gain administrative privileges.

Alcatel Speed Touch Home ADSL Modem allows remote attackers to cause a denial of service (reboot) via a network scan with unusual packets, such as nmap with OS detection.

Alcatel ADSL modems allow remote attackers to access the Trivial File Transfer Protocol (TFTP) to modify firmware and configuration via a bounce attack from a system on the local area network (LAN) side, which is allowed to access TFTP without authentication.

Alcatel Speed Touch running firmware KHDSAA.108 and KHDSAA.132 through KHDSAA.134 has a TFTP server running without a password, which allows remote attackers to change firmware versions or the device's configurations.

Alcatel Speed Touch ADSL modem running firmware KHDSAA.108, KHDSAA.132, KHDSBA.133, and KHDSAA.134 has a blank default password, which allows remote attackers to gain unauthorized access.

The challenge-response authentication of the EXPERT user for Alcatel Speed Touch running firmware KHDSAA.108 and KHDSAA.132 through KHDSAA.134 allows remote attackers to gain privileges by directly computing the response based on information that is provided by the device during login.

Xylan OmniSwitch before 3.2.6 allows remote attackers to bypass the login prompt via a CTRL-D (control d) character, which locks other users out of the switch because it only supports one session at a time.
