Description

This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Cisco ICM. Authentication is not required to exploit this vulnerability.

The flaw exists within the Agent.exe component which listens by default on TCP port 40078. When handling the HandleUpgradeTrace packet type the process blindly copies user supplied data into a fixed-length buffer on the stack. A remote attacker can exploit this vulnerability to execute arbitrary code under the context of the SYSTEM user.
