CVE-2022-0815Network attack vector

Unauthenticated settings access and system fingerprinting

Published Mar 10, 2022 · Updated Aug 2, 2024

Improper access control in McAfee WebAdvisor Chrome and Edge extensions 8.1.0.1895 and earlier allows remote attackers to read system details. Trellix has not published the extension handler, request path, or missing authorization check that exposes those resources. No account or user interaction is required; access can fingerprint the host, alter WebAdvisor settings, and let malicious content avoid execution when McAfee software is detected.
