SEC Consult Vulnerability Lab reported this vulnerability to Siemens. General Recommendations Operators of critical power systems (e.g. TSOs or DSOs) worldwide are usually required by regulations to build resilience into the power grids by applying multi-level redundant secondary protection schemes. It is therefore recommended that the operators check whether appropriate resilient protection measures are in place. The risk of cyber incidents impacting the grid's reliability can thus be minimized by virtue of the grid design. Siemens strongly recommends applying the provided security updates using the corresponding tooling and documented procedures made available with the product. If supported by the product, an automated means to apply the security updates across multiple product instances may be used. Siemens strongly recommends prior validation of any security update before being applied, and supervision by trained staff of the update process in the target environment. As a general security measure Siemens strongly recommends to protect network access with appropriate mechanisms (e.g. firewalls, segmentation, VPN). It is advised to configure the environment according to our operational guidelines in order to run the devices in a protected IT environment.

View CSAF Summary ABB became aware of vulnerability in the products versions listed as affected in the advisory. An update is available that resolves publicly reported vulnerability. An attacker who successfully exploited these vulnerabilities could cause a crash, denial-of-service (DoS), or potentially remote code execution. The following versions of ABB AC500 V3 Stack Buffer Overflow in Cryptographic Message Syntax are affected: AC500 V3 PM5xxx 3.9.0, 3.9.0_HF1 CVSS Vendor Equipment Vulnerabilities v3 9.8 ABB ABB AC500 V3 Stack Buffer Overflow in Cryptographic Message Syntax Out-of-bounds Write Background Critical Infrastructure Sectors: Chemical, Critical Manufacturing, Energy, Water and Wastewater Countries/Areas Deployed: Worldwide Company Headquarters Location: Switzerland Vulnerabilities Expand All + CVE-2025-15467 When parsing CMS (Auth)EnvelopedData structures that use AEAD ciphers such as AES-GCM, the IV (Initialization Vector) encoded in the ASN.1 parameters is copied into a fixed-size stack buffer without verifying that its length fits the destination. An attacker can supply a crafted CMS message with an oversized IV, causing a stack-based out-of-bounds write before any authentication or tag verification occurs. Because the overflow occurs prior to authentication, no valid key material is required to trigger it. While exploitability to remote code execution depends on platform and toolchain mitigations, the stack-based write primitive represents a severe risk.

View CSAF Summary ABB became aware of severe vulnerability in the products versions listed as affected in the advisory. The Windows gateway is accessible remotely by default. Unauthenticated attackers can therefore search for PLCs, but the user management of the PLCs prevents the actual access to the PLCs – unless it is disabled The following versions of ABB Automation Builder Gateway for Windows are affected: Automation Builder <2.9.0, 2.9.0 CVSS Vendor Equipment Vulnerabilities v3 5.3 ABB ABB Automation Builder Gateway for Windows Initialization of a Resource with an Insecure Default Background Critical Infrastructure Sectors: Chemical, Critical Manufacturing, Energy, Water and Wastewater Countries/Areas Deployed: Worldwide Company Headquarters Location: Switzerland Vulnerabilities Expand All + CVE-2024-41975 The gateway serves as a communication channel for various clients to AC500 PLCs. By default, the gateway listens on all available network adapters on port 1217 and can therefore be accessed remotely. How-ever, remote access to the gateway is only required in certain network configurations. Since the gateway is usually accessed locally, many users are unaware of this remote access option, which can enable scan-ning of and access to restricted PLC networks. Unauthenticated attackers can therefore search for PLCs, but the user management of the PLCs prevents the actual access to the PLCs – unless it is disabled. Please note that the gateway for Windows can be installed as a separate setup or as part of other setups such as the CODESYS Development System V3 setup or the CODESYS OPC DA Server setup. View CVE Details Affected Products ABB Automation Builder Gateway for Windows Vendor: ABB Product Version: ABB Automation Builder <2.9.0 Product Status: fixed, known_affected Remediations Vendor fix If remote access is not required, check the "LocalAddress" setting in the [CmpGwCommDrvTcp] section of the Gateway's configuration file as follows (restart of gateway required in case of changes): [CmpGwCommDrvTcp] LocalAddress=127.0.0.1 ; allow access only from the local computer The gateway configuration file can be located at (example for Automation Builder 2.8): %ProgramFiles%\ABB\AB2.8\AutomationBuilder\GatewayPLC\Gateway.cfg Starting with Automation Builder version 2.9.0 the vulnerability is closed by setting the default for the gateway to local access. Automation Builder 2.9.0 is available for download from the related download site. https://www.abb.com/global/en/areas/motion/digital-tools/automation-builder/software-download Workaround Workarounds are specific measures that a user can take to help block an attack, for example, temporarily disabling the vulnerable feature may remove the exposure with well-known impact on functionality. ABB has tested the following workarounds. Although these workarounds will not correct the underlying vulnerability, they can help block known attack vectors. When a workaround reduces functionality, this is identified below as “Impact of workaround”. The vulnerability can be closed by enabling local access only.
