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.

Risk evaluation

Several vulnerabilities in the Wibu Systems CodeMeter Runtime affect the SICK products Sentio Creator, Sentio Compose, Safety Designer, Stream Editor, CODE-LOC, LiDAR-LOC, PLB, SIM1200-2A1A130 LiDAR-LOC and multiple SICK Industrial PCs (APU0G00, APU0G50, APU0G03, APU3F00, APU4600, APU8G00 and APU8G20), which ship with CodeMeter Runtime as part of their preinstalled image. For Sentio Compose, Safety Designer, Stream Editor and PLB, only CVE-2026-81572 is relevant. Vulnerabilities requiring the CodeMeter Runtime to be configured as a server are not applicable to default Sentio Compose, Safety Designer, Stream Editor and PLB installations, as the runtime is shipped with the Network Server and CmWAN Server functionalities disabled. Customers who have modified the default configuration and enabled CodeMeter server functionality should review the remaining vulnerabilities for potential impact. The vulnerabilities could potentially affect the integrity, confidentiality, and availability of the affected products.

Mitigatiesamenvatting

Customers are strongy recommended to update the Codemeter Runtime to the latest version (>= 9.10). The software can be downloaded directly on the Wibu Systems website: https://www.wibu.com/de/support/anwendersoftware/anwendersoftware.html
