Security readout for executives and security teams

CVE-2018-0093 is a reflected XSS flaw in the Cisco Web Security Appliance web management interface. An attacker would need to convince an interface user to open a crafted link, potentially letting script run in that user's browser context and exposing browser-based sensitive information. Exposure is likely limited to organizations running Cisco Web Security Appliance where administrators use the web management interface. Risk increases if that interface is reachable from broader networks or administrators can be targeted through phishing-like links. Treat this as a moderate-priority management-plane issue. It requires user interaction, but successful exploitation could affect administrative browser sessions. Prioritize verification and Cisco-guided remediation for internet-reachable or broadly accessible WSA management interfaces. Mitigation focus: Review Cisco advisory cisco-sa-20180117-wsa1 for fixed-release or workaround guidance.; Inventory Cisco WSA appliances and identify exposed web management interfaces.; Limit management interface access to trusted administrative networks where operationally possible..
