Cisco Content Switching Module Layer 7 Load Balancing Denial of Service Vulnerability

Cisco Content Switching Module Layer 7 Load Balancing Denial of Service Vulnerability

Cisco Content Switching Module (CSM) and Content Switching Module with SSL (CSM-S) are prone to a denial-of-service vulnerability because of a memory leak. This issue occurs when CSM and CSM-S are configured to use layer 7 load balancing.

An attacker can exploit this issue to cause devices using the module to stop accepting TCP connections or to overload, denying service to legitimate users.
