freeradius: forgery attack

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...

Blast-RADIUS is a vulnerability that affects the RADIUS protocol (CVE-2024-3596)

A vulnerability in the verification of RADIUS Response from a RADIUS server has been disclosed by a team of researchers from UC San Diego and their partners. An attacker, with access to the network where the RADIUS protocol is being transmitted, can spoof a UDP-based RADIUS Response packet to...

Amazon Linux 2 : freeradius (ALAS-2024-2611)

The version of freeradius installed on the remote host is prior to 3.0.27-1. It is, therefore, affected by a vulnerability as referenced in the ALAS2-2024-2611 advisory. RADIUS Protocol under RFC 2865 is susceptible to forgery attacks by a local attacker who can modify any valid Response...

RADIUS Protocol Forgery Vulnerability (Blast-RADIUS)

In early July 2024, a group of security researchers found a vulnerability in the RADIUS protocol:CVE-2024-3596: RADIUS Protocol under RFC 2865 is susceptible to forgery attacks by an on-path attacker who can modify any valid Response Access-Accept, Access-Reject, or Access-Challenge to any other...

Unspecified Vulnerability in RADIUS Protocol under RFC 2865

RADIUS Protocol under RFC 2865 is an RFC open source networking protocol. A security vulnerability exists in RADIUS Protocol under RFC 2865, which can be exploited by an attacker to modify any valid response Access-Accept, Access-Reject, or Access-Challenge to any other response using a Choice...

[SECURITY] Fedora 40 Update: freeradius-3.2.5-1.fc40

The FreeRADIUS Server Project is a high performance and highly configurable GPL'd free RADIUS server. The server is similar in some respects to Livingston's 2.0 server. While FreeRADIUS started as a variant of the Cistron RADIUS server, they don't share a lot in common any more. It now has many...

Check Point Response to CVE-2024-3596 - Blast-RADIUS attack

Cause The Blast-RADIUS attack allows a man-in-the-middle attacker between the RADIUS client and server to forge a valid protocol accept message in response to a failed authentication request. This forgery could give the attacker access to network devices and services without the attacker guessing...

Palo Alto Networks Patches Critical Flaw in Expedition Migration Tool

Palo Alto Networks has released security updates to address five security flaws impacting its products, including a critical bug that could lead to an authentication bypass. Cataloged as CVE-2024-5910 CVSS score: 9.3, the vulnerability has been described as a case of missing authentication in its...

The vulnerability of the RADIUS authentication protocol lies in the ability to bypass the authentication process by using capture-replay techniques to manipulate intercepted messages. Exploiting this vulnerability can allow a malicious actor, operating remotely, to gain unauthorized access by manipulating the authentication response.
