The problem is CSCtd75769 , CSCtd75766 , CSCtd75754 ,and CSCtd75761 It is a problem.Skillfully crafted by a third party Cisco Discovery An arbitrary command may be executed via a protocol packet. Cisco TelePresence is a telepresence conferencing solution developed by Cisco. A remote code execution vulnerability exists in the Cisco TelePresence end device that could allow a non-authenticated proximity attacker to trigger a buffer overflow condition. To exploit this vulnerability, an attacker would have to send a malicious Cisco Discovery Protocol message to the affected system. Since the Cisco Discovery Protocol feature is located at the data link layer, an attacker must send an Ethernet frame directly to the device. Multiple Cisco Telepresence products are prone to a buffer-overflow vulnerability because the application fails to perform adequate boundary-checks on user-supplied data. The attacker can exploit this issue to execute arbitrary code with SYSTEM-level privileges. Successfully exploiting this issue will result in the complete compromise of affected computers. Failed exploit attempts will result in a denial-of-service condition. This issue is being tracked by the following Cisco Bug IDs: CSCtd75754 CSCtd75769 CSCtd75761 CSCtd75764. The solution provides components such as audio and video spaces, which can provide remote participants with a "face-to-face" virtual meeting room effect. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 Cisco Security Advisory: Multiple Vulnerabilities in Cisco TelePresence Recording Server Advisory ID: cisco-sa-20110223-telepresence-ctrs Revision 1.0 For Public Release 2011 February 23 1600 UTC (GMT) +--------------------------------------------------------------------- Summary ======= Multiple vulnerabilities exist within the Cisco TelePresence Recording Server.
