A vulnerability in the Session Initiation Protocol (SIP) of the Cisco TelePresence Codec (TC) and Collaboration Endpoint (CE) Software could allow an unauthenticated, remote attacker to cause a TelePresence endpoint to reload unexpectedly, resulting in a denial of service (DoS) condition. The vulnerability is due to a lack of flow-control mechanisms within the software. An attacker could exploit this vulnerability by sending a flood of SIP INVITE packets to the affected device. An exploit could allow the attacker to impact the availability of services and data of the device, including a complete DoS condition. This vulnerability affects the following Cisco TC and CE platforms when running software versions prior to TC 7.3.8 and CE 8.3.0. Cisco Bug IDs: CSCux94002.

Cisco TelePresence endpoints running either CE or TC software contain a vulnerability that could allow an authenticated, local attacker to execute a local shell command injection. More Information: CSCvb25010. Known Affected Releases: 8.1.x. Known Fixed Releases: 6.3.4 7.3.7 8.2.2 8.3.0.

The XML API in TelePresence Codec (TC) 7.2.0, 7.2.1, 7.3.0, 7.3.1, 7.3.2, 7.3.3, 7.3.4, and 7.3.5 and Collaboration Endpoint (CE) 8.0.0, 8.0.1, and 8.1.0 in Cisco TelePresence Software mishandles authentication, which allows remote attackers to execute control commands or make configuration changes via an API request, aka Bug ID CSCuz26935.

Cisco TelePresence TC before 7.3.4 on Integrator C devices allows remote attackers to bypass authentication via vectors involving multiple request parameters, aka Bug ID CSCuv00604.

CRLF injection vulnerability in Cisco TelePresence TC 6.x before 6.3.4 and 7.x before 7.3.3 on Integrator C SX20 devices allows remote attackers to inject arbitrary HTTP headers and conduct HTTP response splitting attacks via a crafted URL, aka Bug ID CSCut79341.
