CWE-288Published: November 18, 2025· Updated: Jun 17, 2026

9.8

CVSS v3.1

Official Description

The Itel DAB MUX (IDMUX build c041640a) is vulnerable to Authentication Bypass due to improper JWT validation across devices. Attackers can reuse a valid JWT token obtained from one device to authenticate and gain administrative access to any other device running the same firmware, even if the passwords and networks are different. This allows full compromise of affected devices.

Risk Analysis

This critical authentication bypass vulnerability in Itel DAB MUX devices allows an attacker to gain administrative access to any device using a valid JWT token from another device. With a CVSS score of 9.8, this flaw enables full compromise of affected devices, regardless of individual device passwords or network configurations. The lack of an EPSS score means its exploitation likelihood is unknown, but the high CVSS score indicates urgency.

No public exploit is currently known for this vulnerability. It is remotely exploitable over the network with low attack complexity.

Recommended Action

Apply available firmware updates for Itel DAB MUX devices to address improper JWT validation. Implement strong authentication mechanisms and ensure unique, device-specific tokens are used.
