mediumPriorität · verfolgen · 31EPSS 0.013 · 71. PerzentilDEEUUSEPSS · bewertet 2026-10-28
A vulnerability has been identified in Simcenter Femap 2020.2 (All versions < V2020.2.MP3), Simcenter Femap 2021.1 (All versions < V2021.1.MP3). The femap.exe application lacks proper validation of user-supplied data when parsing FEMAP files. This could result in an out of bounds write past the end of an allocated structure, a different vulnerability than CVE-2021-27387. An attacker could leverage this vulnerability to execute code in the context of the current process. (ZDI-CAN-12820)

- SSA-133038SSA-133038: Multiple Modfem File Parsing Vulnerabilities in Simcenter Femap2021-06-08csaf · siemens_psirtDE
Siemens Simcenter Femap is affected by two vulnerabilities that could be triggered when the application reads modfem files. If a user is tricked to open a malicious file with the affected application, this could lead to a crash, and potentially also to arbitrary code execution or data extraction on the target host system. Siemens has released updates for Simcenter Femap and recommends to update to the latest version to fix the vulnerabilities. Siemens recommends to avoid opening of untrusted files from unknown sources.
