CVE-2023-4326Network attack vector

Web-interface confidentiality loss via SHA-1 cipher suites

Published Aug 15, 2023 · Updated Nov 4, 2025

Weak TLS defaults in Broadcom LSA before 7.017.011.000 and Intel RWC3 allow remote attackers to undermine web-interface confidentiality. The web server's default cipher configuration advertises obsolete SHA-1-based suites instead of restricting negotiation to stronger suites. Exposure requires access to the HTTPS management endpoint and negotiation of an affected suite; published evidence establishes confidentiality impact but no direct data modification or service interruption.
