Simcenter Femap: Out-of-bounds Read

CVE-2024-32065 is a high-severity out-of-bounds read vulnerability in Simcenter Femap from Siemens, with a CVSS 3.1 base score of 7.8 out of 10. It can be exploited with local access to the system by an unauthenticated attacker, but only if a user takes part, for example by opening a link or file. The record lists version V2406 as the first without the flaw, so updating Simcenter Femap to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.39% chance of exploitation within 30 days, which is low compared with other CVEs.

Next patch cycle

High severity with no evidence of exploitation so far.

What to do

  1. Update Simcenter Femap to V2406 or a later version.
  2. Update ps_iges_parasolid_translator_component to v27.1.215 or a later version.
  3. Update Ps/iges Parasolid Translator to 27.1.215 or a later version.
  4. Read the advisory on cert-portal.siemens.com for workarounds and exact fixed builds.
  5. Because the attack needs a user to take part, warn users about unexpected links and files related to this product until it is patched.
