Summary
A CWE-754 Improper Check for Unusual or Exceptional Conditions vulnerability exists in Triconex TriStation Emulator V1.2.0, which could cause the emulator to crash when sending a specially crafted packet. The emulator is used infrequently for application logic testing. It is susceptible to an attack only while running in off-line mode. This vulnerability does not exist in Triconex hardware products and therefore has no effect on the operating safety functions in a plant.
Exploit prediction
1.14% chance of exploitation in the next 30 days, higher than 66% of all scored CVEs (FIRST EPSS, 2026-11-08).
