Siemens Solid Edge | CISA

As of January 10, 2023, CISA will no longer be updating ICS security advisories for Siemens product vulnerabilities beyond the initial advisory. For the most up-to-date information on vulnerabilities in this advisory, please see Siemens’ ProductCERT Security Advisories (CERT Services | Services | Siemens Global). 



  • CVSS v4 7.3
  • ATTENTION: Low Attack Complexity
  • Vendor: Siemens
  • Equipment: Solid Edge
  • Vulnerability: Out-of-bounds Read


Successful exploitation of this vulnerability could allow an attacker to cause an out-of-bounds read past the end of an allocated structure while parsing specially crafted files, resulting in code execution.



The following versions of Siemens Solid Edge, a product development tool, are affected:

  • Solid Edge: Versions prior to V223.0.11

3.2 Vulnerability Overview


Solid Edge is affected by an out-of-bounds read vulnerability that could be triggered when the application reads files that contains XT parts. If a user is tricked to open a malicious file with the affected applications, an attacker could leverage the vulnerability to perform remote code execution in the context of the current process.

CVE-2023-49125 has been assigned to this vulnerability. A CVSS v3 base score of 7.8 has been calculated; the CVSS vector string is (CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H).

A CVSS v4 score has also been calculated for CVE-2023-49125. A base score of 7.3 has been calculated; the CVSS vector string is (CVSS4.0/AV:L/AC:H/AT:N/PR:N/UI:P/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N.


  • CRITICAL INFRASTRUCTURE SECTORS: Critical Manufacturing, Commercial Facilities, Energy, Healthcare and Public Health


Siemens reported this vulnerability to CISA.


Siemens has identified the following specific workarounds and mitigations users can apply to reduce risk:

  • Solid Edge: Do not open untrusted files containing XT parts in Solid Edge.
  • Solid Edge: Update to V223.0.11 or later version

As a general security measure, Siemens recommends protecting network access to devices with appropriate mechanisms. To operate the devices in a protected IT environment, Siemens recommends configuring the environment according to Siemens’ operational guidelines for industrial security and following recommendations in the product manuals.

Additional information on industrial security by Siemens can be found on the Siemens industrial security webpage

For more information see the associated Siemens security advisory SSA-382651 in HTML and CSAF.

CISA recommends users take defensive measures to minimize the risk of exploitation of this vulnerability, such as:

  • Minimize network exposure for all control system devices and/or systems, ensuring they are not accessible from the internet.
  • Locate control system networks and remote devices behind firewalls and isolating them from business networks.
  • When remote access is required, use more secure methods, such as Virtual Private Networks (VPNs). Recognize VPNs may have vulnerabilities, should be updated to the most recent version available, and are only as secure as the connected devices.

CISA reminds organizations to perform proper impact analysis and risk assessment prior to deploying defensive measures.

CISA also provides a section for control systems security recommended practices on the ICS webpage on Several CISA products detailing cyber defense best practices are available for reading and download, including Improving Industrial Control Systems Cybersecurity with Defense-in-Depth Strategies.

CISA encourages organizations to implement recommended cybersecurity strategies for proactive defense of ICS assets.

Additional mitigation guidance and recommended practices are publicly available on the ICS webpage at in the technical information paper, ICS-TIP-12-146-01B–Targeted Cyber Intrusion Detection and Mitigation Strategies.

Organizations observing suspected malicious activity should follow established internal procedures and report findings to CISA for tracking and correlation against other incidents.

CISA also recommends users take the following measures to protect themselves from social engineering attacks:

No known public exploitation specifically targeting this vulnerability has been reported to CISA at this time. This vulnerability is not exploitable remotely.
