Summary

CVE-2026-23715 is a high-severity Out-of-bounds Write (CWE-787) vulnerability in Siemens Simcenter Femap. Its CVSS base score is 7.3 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploitation for Privilege Escalation (T1068); ranked at the 6th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified map to SA-11 (Developer Testing and Evaluation) and SA-15 (Development Process, Standards, and Tools) — see the control section below for these in your framework.

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

CVE-2026-23715 is an out-of-bounds write vulnerability (CWE-787) affecting Simcenter Femap and Simcenter Nastran in all versions prior to V2512. The flaw occurs while parsing specially crafted XDB files, potentially allowing an attacker to execute arbitrary code in the context of the current process. Published on 2026-02-10 with a CVSS v3.1 base score of 7.8 (AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H), it poses a high-impact risk to affected systems.

Exploitation requires local access to the target system with no privileges needed, but user interaction is necessary, such as convincing a user to open a malicious XDB file in the vulnerable application. Successful exploitation enables arbitrary code execution with the privileges of the running process, potentially leading to full system compromise if the application runs with elevated permissions.

Siemens has published security advisory SSA-965753 detailing the vulnerability and mitigation steps, available at https://cert-portal.siemens.com/productcert/html/ssa-965753.html. Security practitioners should consult this advisory for patch information and apply updates to versions V2512 or later.

Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

SA-11 Developer Testing and Evaluation good match

Developer testing and evaluation (including fuzzing and bounds checks) finds out-of-bounds write flaws before deployment.

SA-15 Development Process, Standards, and Tools partial match

Requiring documented secure-development standards and tools can mandate bounds-checked coding practices that avoid the weakness.

SI-10 Information Input Validation partial match

Input validation can structurally reject or sanitize data that would otherwise trigger an out-of-bounds write.

SI-16 Memory Protection partial match

Memory-protection mechanisms limit the exploitability and blast radius of a successful out-of-bounds write.
