Overview

CVE-2026-25715 is a critical-severity vulnerability. It was published on February 20, 2026 and has a CVSS 3.1 base score of 9.8 (CRITICAL).

This vulnerability has a CVSS 3.1 base score of 9.8, rated CRITICAL. It can be exploited remotely over the network. No authentication or special privileges are required for exploitation.

Technical 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.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
