There is a series of vulnerabilities in Cisco s Unified Videoconferencing product, including a hardcoded password for several powerful accounts that can t be changed or deleted. That bug and others disclosed Wednesday can be used to gain complete control of the device and possibly compromise other parts of the internal network. The password vulnerability, which is the most severe of the bugs identified this week by Matta Consulting, is only present on systems running Linux operating systems. The company warned its customers about the bug in an advisory.
