Authentication bypass via blank admin credentials in PUSR USR-W610 (<= 3.1.1.0)
CVE-2026-25715 is a weak password requirements vulnerability in the Jinan USR IOT Technology Limited (PUSR) USR-W610 Wi‑Fi router (versions up to and including 3.1.1.0) where the web management interface permits the administrator username and password to be set to blank (empty) values. After these blank credentials are applied, the device accepts authentication attempts with empty credentials over both the web management interface and the Telnet service, effectively disabling authentication on critical management channels and enabling unauthorized administrative access.
