Summary
A CWE-754 – Improper Check for Unusual or Exceptional Conditions vulnerability exists in Magelis HMI Panels (all versions of - HMIGTO, HMISTO, XBTGH, HMIGTU, HMIGTUX, HMISCU, HMISTU, XBTGT, XBTGT, HMIGXO, HMIGXU), which could cause a temporary freeze of the HMI when a high rate of frames is received. When the attack stops, the buffered commands are processed by the HMI panel.
