What is CVE-2025-52543?

The E3 Site Supervisor Control application services, specifically in firmware versions below 2.31F01, implement client-side hashing for authentication. This flawed approach allows attackers to exploit the system by capturing the password hash, enabling unauthorized access without needing the actual password. Users are strongly advised to update their firmware to mitigate this authentication weakness.
