Imagine a computer system that controls a power grid. If someone hacks into this system, they can cause a big problem. To fix this, the company that made the system, Siemens, is releasing a new version that will make it harder for hackers to get in.
Analysis
Vulnerability Overview
The Siemens Desigo CC is vulnerable to an OpenSSL stack-based buffer overflow, which can cause a denial of service or potentially allow for remote code execution. This vulnerability affects critical infrastructure sectors, including critical manufacturing, and can have severe consequences if exploited.
Affected Products
The following versions of Siemens Desigo CC are affected:
- Desigo CC family V7 vers:all/* (CVE-2025-15467)
- Desigo CC family V8 vers:all/* (CVE-2025-15467)
- Desigo CC family V9 vers:intdot/<9.0.1 (CVE-2025-15467)
Remediations
Currently, no fix is available. Siemens recommends updating to V9.0 QU1 or later version for affected products. Additionally, Siemens recommends applying the provided security updates using the corresponding tooling and documented procedures made available with the product.
General Recommendations
Operators of critical power systems 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.
Key points
- Siemens Desigo CC is vulnerable to an OpenSSL stack-based buffer overflow.
- The vulnerability can cause a denial of service or potentially allow for remote code execution.
- Siemens has released new versions for several affected products and recommends updating to the latest versions.
- Operators of critical power systems should check if appropriate resilient protection measures are in place.
- Siemens recommends applying the provided security updates using the corresponding tooling and documented procedures made available with the product.
If Siemens releases the new version of the system quickly, it can help prevent hackers from causing problems. This can also help the power grid run more smoothly and reliably.
If the new version of the system is not released quickly, hackers may be able to cause problems and disrupt the power grid. This can lead to power outages and other issues.
