Description

RADIUS Protocol under RFC 2865 is susceptible to forgery attacks by a local attacker who can modify any valid Response (Access-Accept, Access-Reject, or Access-Challenge) to any other response using a chosen-prefix collision attack against MD5 Response Authenticator signature. A vulnerability in the RADIUS (Remote Authentication Dial-In User Service) protocol allows attackers to forge authentication responses when the Message-Authenticator attribute is not enforced. This issue arises from a cryptographically insecure integrity check using MD5, enabling attackers to spoof UDP-based RADIUS response packets. This can result in unauthorized access by modifying an Access-Reject response to an Access-Accept response, thereby compromising the authentication process.
