Name of the Vulnerable Software and Affected Versions Cisco Web Security Appliance (WSA) versions 8.0.6-078 through 8.0.6-115

Description The issue allows remote attackers to cause a denial of service, resulting in a service outage. This is achieved by flooding the system with TCP traffic, which leads to delays in DNS resolution.

Recommendations For versions 8.0.6-078 through 8.0.6-115, consider implementing rate limiting on TCP traffic to mitigate the risk of DNS resolution delays. As a temporary workaround, restrict access to the DNS resolution service to minimize the risk of exploitation. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
