Tecnomatix Plant Simulation V2302: Incorrect Type Conversion or Cast
CVE-2024-35303 is a high-severity incorrect type conversion or cast vulnerability in Tecnomatix Plant Simulation V2302 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 V2302.0012 as the first without the flaw, so updating Tecnomatix Plant Simulation V2302 to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.25% 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 Tecnomatix Plant Simulation V2302 to V2302.0012 or a later version.
- Update Tecnomatix Plant Simulation V2404 to V2404.0001 or a later version.
- Because the attack needs a user to take part, warn users about unexpected links and files related to this product until it is patched.
