CVE-2025-13053Network attack vector

UPS configuration disclosure via unenforced TLS verification

Published Dec 12, 2025 · Updated Dec 12, 2025

Missing encryption in ASUSTOR ADM 4.1.0 through 4.3.3.RKD2 and 5.0.0 through 5.1.0.RN42 allows attackers to read UPS configuration data. The UPS client accepts a TLS connection without enforcing server-certificate verification when it retrieves status or sends control commands. Exploitation requires network interception between a NAS configured for UPS access and its UPS server; the documented consequence is disclosure of UPS server configuration information.
