## What is CVE-2026-25715?

CVE-2026-25715 is a critical authentication bypass vulnerability in Jinan USR IOT Technology Limited (PUSR) USR-W610, published on 20 Feb 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

The web management interface of the device allows the administrator 
username and password to be set to blank values. Once applied, the 
device permits authentication with empty credentials over the web 
management interface and Telnet service. This effectively disables 
authentication across all critical management channels, allowing any 
network-adjacent attacker to gain full administrative control without 
credentials.
