Siemens has released new versions for several affected products and recommends to update to the latest versions. Siemens is preparing further fix versions and recommends countermeasures for products where fixes are not, or not yet available.

Mitigation summary

Currently no fix is planned

Risk evaluation

Affected products do not properly restrict access permissions to a local Windows Named Pipe and do not properly sanitize user-controllable input sent to that Named Pipe. This could allow a local authenticated attacker to cause a type confusion and execute arbitrary code within the affected application and its privileges. Siemens has released new versions for several affected products and recommends to update to the latest versions. Siemens is preparing further fix versions and recommends specific countermeasures for products where fixes are not, or not yet available.

Mitigation summary

On Desktop systems: Execute affected software on Windows hosts where only a single user is configured

Siemens has released a new version for RUGGEDCOM CROSSBOW Station Access Controller (SAC) and recommends to update to the latest version.

Mitigation summary

Update to V6.0 or later version

Risk evaluation

Multiple vulnerabilities have been identified in the additional GNU/Linux subsystem of the SIMATIC S7-1500 TM MFP V1.1.1. Siemens is preparing fixes and recommends specific mitigations for products where fixes are not or not yet available.

Mitigation summary

Limit access to the interactive shell of the additional GNU/Linux subssytem to trusted personnel only.

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.

Mitigation summary

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

Risk evaluation

Multiple vulnerabilities have been identified in the additional GNU/Linux subsystem of the SIMATIC S7-1500 TM MFP V1.0. Siemens has released a new version for SIMATIC S7-1500 TM MFP - GNU/Linux subsystem and recommends to update to the latest version. SIMATIC S7-1500 TM MFP V1.0 is no longer maintained and there won't be any update to the CVE list anymore. Please update to the latest version. This advisory lists vulnerabilities for firmware version V1.0 only; for V1.1 refer to Siemens Security Advisory SSA-265688 (https://cert-portal.siemens.com/productcert/html/ssa-265688.html).

Mitigation summary

Mitigation summary

See the official CISA advisory for mitigating measures.

Risk evaluation

Simcenter Nastran is affected by a stack overflow vulnerability that could be triggered when an application binary reads arbitrary string as a file argument. If a user is tricked to run one of the impacted application binary with a malicious string, an attacker could leverage the vulnerability to perform remote code execution in the context of the current process. Siemens has released new versions for the affected products and recommends to update to the latest versions.

Mitigation summary

Update to V2606 or later version

Risk evaluation

Siemens LOGO! Soft Comfort contains multiple vulnerabilities in its project-file encryption and password handling mechanisms. A local attacker could exploit these vulnerabilities to extract the master key, allowing them to decrypt project data or remove project passwords. The lack of password salting enables offline dictionary or brute-force attacks against the password hashes. Successful exploitation could result in unauthorized access to, or modification of, sensitive project logic and configurations. Siemens has released a new version for LOGO! Soft Comfort and recommends to update to the latest version.

Mitigation summary

Update to V9 or later version Note: A hardware upgrade to LOGO! V9 BM or later is also required to avoid compatibility mode, in which the vulnerabilities addressed by this advisory remain present.

Risk evaluation

Solid Edge is affected by multiple file parsing vulnerabilities that could be triggered when the application reads specially crafted files in PAR, PSM or DFT format.

Mitigation summary

Update to V225.0 Update 15 or later version

Risk evaluation

Simcenter Femap contains two file parsing vulnerabilities that could be triggered when the application reads files in BMP file format. If a user is tricked to open a malicious file with the affected application, this could lead the application to crash or potentially lead to arbitrary code execution. Siemens has released a new version for Simcenter Femap and recommends to update to the latest version.

Mitigation summary

Update to V2606.0001 or later version

Risk evaluation

Parasolid is affected by an out of bounds read vulnerability that could be triggered when the application reads files in X_T format.
