Security readout for executives and security teams
CVE-2018-0353 affects Cisco Web Security Appliance deployments using Layer 4 Traffic Monitor. An unauthenticated remote attacker could cause traffic that should be blocked to pass through the appliance. The business risk is failed enforcement of web security policy, especially where WSA is trusted to stop prohibited IPv4 or IPv6 traffic. Exposure is limited to Cisco Web Security Appliance instances running the listed AsyncOS release trains with Layer 4 Traffic Monitor enabled. Internet-facing or network-edge deployments matter most because exploitation is described as unauthenticated and remote. Treat this as high priority where Cisco WSA is used as a security enforcement point. The vulnerability may let denied traffic pass, reducing confidence in web security controls. Urgency depends on whether affected versions and L4TM are actually present. Mitigation focus: Inventory Cisco WSA appliances and identify AsyncOS versions 10.5.1, 10.5.2, and 11.0.0.; Confirm whether Layer 4 Traffic Monitor is enabled on each WSA appliance.; Review Cisco advisory cisco-sa-20180606-wsa for vendor-approved fixes or workarounds..
