Cisco TelePresence Collaboration Endpoint Software H.323 DoS (cisco-sa-ce-roomos-dos-c65x2Qf2)

high Nessus Plugin ID 160289

Synopsis

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

Description

According to its self-reported version, Cisco TelePresence Collaboration Endpoint Software is affected by a vulnerability in the packet processing functionality that could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. This vulnerability is due to insufficient input validation. An attacker could exploit this vulnerability by sending crafted H.323 traffic to an affected device. A successful exploit could allow the attacker to cause the affected device to either reboot normally or reboot into maintenance mode, which could result in a DoS condition on the device.

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 CSCvz55702
