Cisco TelePresence Collaboration Endpoint DoS (cisco-sa-tpce-rmos-mem-dos-rck56tT)

low Nessus Plugin ID 153944

Synopsis

The remote device is missing a vendor-supplied security patch.

Description

According to its self-reported version, Cisco TelePresence Collaboration Endpoint is affected by a denial of service (DoS) vulnerability in the memory management. This allows an authenticated, local attacker to corrupt a shared memory segment, resulting in a DoS condition. This vulnerability is due to insufficient access controls to a shared memory resource. An attacker could exploit this vulnerability by corrupting a shared memory segment on an affected device. A successful exploit could allow the attacker to cause the device to reload. The device will recover from the corruption upon reboot.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Upgrade to the relevant fixed version referenced in Cisco bug ID CSCvy60378
