PatchTheCVECVE-2025-63217: The Itel DAB MUX (IDMUX build c041640a) is vulnerable to Authentication Bypass due to improper JWT validation
CVE-2025-63217 is a critical-severity flaw (CVSS 9.8) affecting id mux firmware. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.
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.
Why this priority
- Critical severity
- Public exploit reference
- CISA SSVC: automatable with total technical impact
- Remotely exploitable, no login, no user action
A fixed release or distro patch exists.
