Detailed vulnerability description
The vulnerability allows a local administrator attacker to perform command injection on the target system.
The weakness exists in the CLI command-parsing code of Cisco Meeting Server due to insufficient validation of user-supplied input at the CLI for certain commands. A local attacker can authenticate to the affected application with valid administrator credentials, submit and execute a specially crafted CLI command and gain root privileges on the system.
Successful exploitation of the vulnerability results in privilege escalation.
