Vulnerability from github – Published: 2025-08-08 18:32 – Updated: 2025-08-08 18:32

Details

The affected product allows firmware updates to be downloaded from EG4's website, transferred via USB dongles, or installed through EG4's Monitoring Center (remote, cloud-connected interface) or via a serial connection, and can install these files without integrity checks. The TTComp archive format used for the firmware is unencrypted and can be unpacked and altered without detection.
