If a user is tricked to open a malicious file with the affected application, an attacker could leverage the vulnerability to perform remote code execution in the context of the current process. Siemens has released a new version for Simcenter Femap and recommends to update to the latest version.\n\nThe following versions of Siemens Simcenter Femap are affected:\n\n\n\nSimcenter Femap vers:intdot/<2512.0003\n\n<div class=\"csaf-table\">\n\n\n\n\nCVSS\nVendor\nEquipment\nVulnerabilities\n\n\n\n\nv3 7.8\nSiemens\nSiemens Simcenter Femap\nHeap-based Buffer Overflow\n\n\n\n</div>\n\nBackground\n\n\n\nCritical Infrastructure Sectors: Critical Manufacturing\n\nCountries/Areas Deployed: Worldwide\n\nCompany Headquarters Location: Germany\n\n\n\n\nVulnerabilities\n<div class=\"csaf-accordion\">\n\nExpand All +\n<div class=\"csaf-accordion-item\">\n\nCVE-2025-12659\n<div class=\"csaf-accordion-content\">\n\nThe affected applications contains a memory corruption vulnerability while parsing specially crafted IPT files.

In order to operate the devices in a protected IT environment, Siemens recommends to configure the environment according to Siemens' operational guidelines for Industrial Security (Download: https://www.siemens.com/cert/operational-guidelines-industrial-security), and to follow the recommendations in the product manuals. Additional information on Industrial Security by Siemens can be found at: https://www.siemens.com/industrialsecurity\n\n\n\nAdditional Resources\n\nFor further inquiries on security vulnerabilities in Siemens products and solutions, please contact the Siemens ProductCERT: https://www.siemens.com/cert/advisories\n\n\n\nTerms of Use\n\nThe use of Siemens Security Advisories is subject to the terms and conditions listed on: https://www.siemens.com/productcert/terms-of-use.\n\n\n\nLegal Notice and Terms of Use\n\nThis product is provided subject to this Notification (https://www.cisa.gov/notification) and this Privacy & Use policy (https://www.cisa.gov/privacy-policy).\n\n\n\nRecommended Practices\n\nCISA recommends users take defensive measures to minimize the exploitation risk of these vulnerabilities.\n\nMinimize network exposure for all control system devices and/or systems, and ensure they are not accessible from the internet.\n\nLocate control system networks and remote devices behind firewalls and isolate them from business networks.\n\nWhen remote access is required, use more secure methods, such as Virtual Private Networks (VPNs), recognizing VPNs may have vulnerabilities and should be updated to the most recent version available. Also recognize VPN is only as secure as its connected devices.\n\nCISA reminds organizations to perform proper impact analysis and risk assessment prior to deploying defensive measures.\n\nCISA also provides a section for control systems security recommended practices on the ICS webpage on cisa.gov. 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.\n\nCISA 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 cisa.gov in the technical information paper, ICS-TIP-12-146-01B--Targeted Cyber Intrusion Detection and Mitigation Strategies.\n\nOrganizations observing suspected malicious activity should follow established internal procedures and report findings to CISA for tracking and correlation against other incidents.\n\n\n\nAdvisory Conversion Disclaimer\n\nThis ICSA is a verbatim republication of Siemens ProductCERT SSA-870926 from a direct conversion of the vendor's Common Security Advisory Framework (CSAF) advisory.
