Technical description

Intel Crosswalk before 19.49.514.5, 20.x before 20.50.533.11, 21.x before 21.51.546.0, and 22.x before 22.51.549.0 interprets a user's acceptance of one invalid X.509 certificate to mean that all invalid X.509 certificates should be accepted without prompting, which makes it easier for man-in-the-middle attackers to spoof SSL servers and obtain sensitive information via a crafted certificate.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
