CVE-2024-0310Network attack vector

Cross-site scripting via CSP enforcement downgrade

Published Jan 10, 2024 · Updated Sep 3, 2024

Cross-site scripting in Trellix Endpoint Security Web Control before 10.7.0 Update 15 allows remote attackers to bypass enforced CSP. The ENS Control browser extension rewrites an attacker-influenced response-header parameter so an enforcing Content-Security-Policy becomes report-only. A user must browse attacker-controlled content; successful exploitation permits script execution in the affected page context, exposing or modifying browser-accessible data.
