CVE-2024-1509: Broadcom Brocade Active Support Connectivity Gateway

Critical severity, CVSS 9.1. EPSS: 0.4% chance of exploitation in the next 30 days.

Brocade ASCG before 3.2.0 Web Interface is not enforcing HSTS, as defined by RFC 6797. HSTS is an optional response header that can be configured on the server to instruct the browser to only communicate via HTTPS. The lack of HSTS allows downgrade attacks, SSL-stripping man-in-the-middle attacks, and weakens cookie-hijacking protections.

Affected products

• Broadcom Brocade Active Support Connectivity Gateway: up to and including 3.1.0
