Cisco Security Advisory: Denial of Service Vulnerability in Cisco Wide Area Application Services (WAAS) Software

Tags:
security management

Overview The Cisco Wide Area Application Services (WAAS) software contains a Denial of Service (DoS) vulnerability that may cause some devices that run WAAS software (WAE appliance and NM-WAE 502 module) to stop processing all types of traffic, including data traffic and management traffic. This condition may occur if a device running WAAS software is configured for Edge Services, which utilizes Common Internet File System (CIFS) optimization and receives a flood of TCP SYN packets on port 139 or 445. Cisco has made free software available to address this vulnerability for affected customers. Workarounds are available to mitigate the effects of this vulnerability.
