Vulnerabilidades

The Comcast firmware on Motorola MX011ANM (firmware version MX011AN_2.9p6s1_PROD_sey) and Xfinity XR11-20 Voice Remote devices allows local users to upload arbitrary firmware images to an XR11 by leveraging root access. In other words, there is no protection mechanism involving digital signatures for the firmware.

The Comcast firmware on Motorola MX011ANM (firmware version MX011AN_2.9p6s1_PROD_sey) devices allows physically proximate attackers to execute arbitrary commands as root by pulling up the diagnostics menu on the set-top box, and then posting to a Web Inspector route.

The Comcast firmware on Motorola MX011ANM (firmware version MX011AN_2.9p6s1_PROD_sey) devices allows physically proximate attackers to access an SNMP server by connecting a cable to the Ethernet port, and then establishing communication with the device's link-local IPv6 address.

The Comcast firmware on Motorola MX011ANM (firmware version MX011AN_2.9p6s1_PROD_sey) devices allows physically proximate attackers to read arbitrary files by pressing "EXIT, Down, Down, 2" on an RF4CE remote to reach the diagnostic display, and then launching a Remote Web Inspector script.

The Comcast firmware on Motorola MX011ANM (firmware version MX011AN_2.9p6s1_PROD_sey) devices allows remote attackers to enable a Remote Web Inspector that is accessible from the public Internet.

The Comcast firmware on Motorola MX011ANM (firmware version MX011AN_2.9p6s1_PROD_sey) devices allows remote attackers to conduct successful forced-pairing attacks (between an RF4CE remote and a set-top box) by repeatedly transmitting the same pairing code.
