Summary
A vulnerability in the deployment module of Cisco WebEx Meeting Center could
allow an unauthenticated, remote attacker to bypass the passphrase check
during the deployment of a virtual machine.
The vulnerability is due to a flaw in the validation of the passphrase.
An attacker could exploit this vulnerability by accessing the deployment URL
without the passphrase. A successful exploit could allow the attacker to start
the deployment of a virtual machine or interrupt an existing deployment by
resetting the status of the deployment itself. This vulnerability can be
exploited only if the virtual machine is not already deployed or during the
deployment itself. After the virtual machine is deployed, the deployment URL
is not valid anymore so the vulnerability cannot be exploited.
