CVE-2023-51573Network attack vector

Unauthenticated manager access via exposed password update

Published Apr 1, 2024 · Updated Aug 2, 2024

Authentication bypass in Voltronic Power ViewPower Pro 2.0-22165 allows remote attackers to gain manager access without credentials. The remotely exposed updateManagerPassword function permits password changes without enforcing authentication before the operation. Network reachability to the web interface is the only reported gate, after which manager access permits monitoring and control of connected UPS systems.
