Vulnerability from variot - Updated: 2025-09-30 23:20

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. Magelis HMI Panel Contains an exceptional condition check vulnerability.Service operation interruption (DoS) There is a possibility of being put into a state. Schneider Electric Magelis HMIGTO, etc. are a human-machine interface control panel of Schneider Electric in France. A code issue vulnerability exists in several Schneider Electric products. This vulnerability stems from improper design or implementation problems in the code development process of network systems or products. The following products and versions are affected: Schneider Electric HMIGTO; HMISTO; XBTGH; HMIGTU; HMIGTUX; HMISCU; HMISTU; XBTGT; XBTGT; HMIGXO; HMIGXU
