Risk Evaluation

This advisory documents the impact of CVE-2024-3596 (also dubbed "Blastradius"), a vulnerability in the RADIUS protocol, to SIPROTEC, SICAM and related products. The vulnerability could allow on-path attackers, located between a Network Access Server (the RADIUS client, e.g., a SICAM device) and a RADIUS server, to forge Access-Request packets in a way that enables them to modify the corresponding server response packet at will, e.g., turning an "Access-Reject" message into an "Access-Accept". This would cause the Network Access Server to grant the attackers access to the network with the attackers desired authorization (and without the need of knowing or guessing legitimate access credentials). Further details incl. external references can be found in the chapter "Additional Information". Siemens has released new versions for several affected products and recommends to update to the latest versions, and to configure the updated systems as recommended in the chapter "Additional Information". Siemens has released new versions for the affected products and recommends to update to the latest versions.See chapter "Additional Information" for details.

Zusammenfassung der Gegenmaßnahmen

Configure the RADIUS server to require the presence of a Message-Authenticator attribute in all Access-Request packets from RADIUS client devices that support it
