Private crypto key stashed in Cisco VoIP manager allows network hijacking

Cisco Systems has released a security update that closes a backdoor allowing attackers to control software that large organizations use to manage voice over IP (VoIP) calls and messaging over their networks.

The default secure shell (SSH) key made it possible for hackers to gain highly privileged administrative access to the Cisco Unified Communications Domain Manager, the networking company warned in an advisory published Wednesday. From there, intruders could execute arbitrary commands or gain persistent access to the systems. The advisory didn't explicitly say that attackers could monitor discussions or track the times that calls or messages were made and who sent and received them, but it wouldn't be surprising if those capabilities were also possible. In addition to VoiP management, the Cisco Unified Communications Domain Manager also allows users to manage Cisco Jabber, a cloud-based service for instant messaging, voice and video communications, desktop sharing, and conferencing.
