Security Bulletin: IBM Security Verify Information Queue still supports older browsers that don't enforce CSRF token protections (CVE-2021-20403)

Security Bulletin

Summary

The IBM Security Verify Information Queue (ISIQ) web application protects against cross-site request forgery (CSRF) attacks by using the SameSite cookie attribute. However, ISIQ's web browser requirements are not current enough to ensure that this cookie attribute gets consistently used. As of v10.0.0, ISIQ has updated its minimum browser requirements to prevent older browsers from bypassing CSRF token protections.
