CVE-2025-27257

Insufficient Verification of Data Authenticity vulnerability in GE Vernova UR IED family devices allows an authenticated user to install a modified firmware. The firmware signature verification is enforced only on the client-side dedicated software Enervista UR Setup, allowing the integration check to be bypassed.

Weakness

The product does not sufficiently verify the origin or authenticity of data, in a way that causes it to accept invalid data.
