Solid Edge SE2024: Integer Underflow (Wrap or Wraparound)
CVE-2024-54095 is a high-severity integer underflow (wrap or wraparound) vulnerability in Solid Edge SE2024 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 V224.0 Update 10 as the first without the flaw, so updating Solid Edge SE2024 to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.17% chance of exploitation within 30 days, which is low compared with other CVEs.
High severity with no evidence of exploitation so far.
What to do
- Update Solid Edge SE2024 to V224.0 Update 10 or a later version.
- Read the advisory on cert-portal.siemens.com for workarounds and exact fixed builds.
