Siemens has identified a vulnerability in its SIMATIC S7-PLCSIM Advanced software that could lead to a denial of service (DoS) condition. This issue arises from the software's inability to manage high-volume multicast network traffic, which can deplete available memory resources and make the application inaccessible. Although no project data is lost during this downtime, the affected application needs to be manually restarted. The vulnerability, tracked as CVE-2026-54429, impacts all versions of the SIMATIC S7-PLCSIM Advanced software and can be exploited by an unauthenticated attacker on the local network. Siemens is currently working on fixes and recommends users take specific countermeasures to mitigate the risk until updates are available.
Siemens has issued a warning about a serious vulnerability affecting its Desigo CC product family, which includes versions V7, V8, and V9 prior to 9.0.1. This vulnerability, identified as CVE-2025-15467, can be exploited by remote attackers to trigger a stack-based buffer overflow, potentially leading to denial of service or even remote code execution. The risk arises when parsing certain CMS messages with maliciously crafted parameters. Siemens has released updates for some affected versions and is advising users to upgrade to the latest versions. For those unable to update immediately, Siemens suggests implementing additional security measures to mitigate the risk. This vulnerability is particularly concerning given the critical infrastructure sectors affected, as these systems are essential for operations worldwide.
ABB has confirmed a vulnerability in its KNX Update Tool that affects classic KNX devices, which do not support the newer KNX Secure standard. This vulnerability, identified as CVE-2026-12705, allows an attacker with physical access to the device's bus to potentially render it unusable or alter its behavior by tampering with the firmware. ABB has stated that there are no software updates available to address this issue due to the inherent security limitations of legacy KNX devices. Users are advised to limit physical access to these devices and avoid using them for sensitive applications, as there are no plans for corrective measures from ABB. This incident highlights ongoing security challenges with older industrial protocols.
