CVE-2024-1509
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedBrocade 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.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceBrocade ASCG versions before 3.2.0 web interface fails to include the HTTP Strict Transport Security (HSTS) header in responses, per RFC 6797. Without HSTS, browsers will accept HTTP connections and cannot defend against SSL-stripping man-in-the-middle attacks or downgrade attacks. Additionally, session cookies are vulnerable to interception when users access the site over unencrypted HTTP.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify if Brocade ASCG web interface is runningAccess the web interface via HTTPS on the default port (typically 443) or check network listening services on the ASCG deviceAffected if The ASCG web interface is accessible and responding to requests
-
Check the installed ASCG versionLog into the ASCG administrative console and navigate to the About or System Information page to view the firmware/software version, or check via CLI command if availableAffected if The version displayed is 3.1.0 or lower
-
Verify HSTS header is missingSend an HTTPS request to the ASCG web interface (e.g., using curl -I https://<ascg-host>/) and inspect the response headers for the Strict-Transport-Security headerAffected if The response does NOT contain a Strict-Transport-Security header in the HTTP response headers
If the Brocade ASCG version is 3.1.0 or lower AND the HTTPS responses from the web interface do not contain a Strict-Transport-Security header, the environment is affected by this vulnerability.
Generated from the published advisory. Verify against your own configuration.
Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scopedEnable HSTS on the Brocade ASCG web server by configuring the Strict-Transport-Security header with an appropriate max-age directive. Consider starting with a shorter max-age and increasing after validating no disruption to client access.
3.2.0
- Obtain Brocade Active Support Connectivity Gateway version 3.2.0 or later from the Broadcom support portal at support.broadcom.com
- Follow the standard upgrade procedure for ASCG, ensuring to back up current configuration before proceeding
- After upgrade, verify HSTS is enabled by inspecting HTTP responses from the web interface for the 'Strict-Transport-Security' header
- Confirm the web interface is accessible only via HTTPS and HSTS is properly enforced
