CVE-2025-53520

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.
