radius protocol

About this tag
The RADIUS protocol is a foundational networking protocol used for authentication, authorization, and accounting (AAA) in enterprise and industrial environments. Recent discussions on WindowsForum highlight a critical vulnerability, CVE-2024-3596, which exploits a chosen-prefix collision attack against the MD5-based RADIUS Response Authenticator defined in RFC 2865. This flaw affects devices from vendors such as Hitachi Energy and Siemens, including substation and network edge products like AFS, AFR, AFF, SIPROTEC, and SICAM. The vulnerability allows local attackers to forge authentication responses, potentially granting or denying network access and compromising device integrity. Mitigation involves enabling the RADIUS Message-Authenticator option and applying vendor firmware updates. These threads underscore the importance of securing RADIUS deployments in critical infrastructure.
