Vulnerability details
The vulnerability allows a remote attacker to cause DoS condition on the target system.
The weakness exists in the Independent Computing Architecture (ICA) accelerator feature for the Cisco Wide Area Application Services (WAAS) due to improper aborting of a connection when an unexpected protocol packet is received. A remote attacker can send a specially crafted ICA traffic and cause an ICA application optimization-related process to restart.
Successful exploitation of the vulnerability results in denial of service.
