Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
An issue was discovered on certain GL-iNet devices, including MT6000, MT3000, MT2500, AXT1800, and AX1800 4.6.2. The SID generated for a specific user is not tied to that user itself, which allows other users to potentially use it for authentication. Once an attacker bypasses the application's authentication procedures, they can generate a valid SID, escalate privileges, and gain full control.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

How this class of weakness works · CWE-863

An authorization check exists but is flawed, so it passes when it should fail. Attackers probe roles and object references to find the gap. Remediation means centralising and correctly implementing the access-control logic, then testing it against every role.

Upgrade available Upgrade to 4.6.4 or later
Fixed in 4.6.4
Recommended fix Moderate confidence

Firmware version 4.6.4 or later for MT2500, AXT1800, and AX1800 devices; contact GL-iNet support for specific fixed firmware versions for B3000, A1300, X300b, X3000, and XE3000 models

  1. Identify your specific GL-iNet device model from the affected list (MT2500, AXT1800, AX1800, B3000, A1300, X300b, X3000, or XE3000)
  2. Access the device's administrative web interface or CLI
  3. Navigate to the firmware update section
  4. Check the current firmware version running on the device
  5. Download the latest firmware from the official GL-iNet support website (gl-inet.com)
  6. Upload and apply the firmware update, ensuring continuous power during the process
  7. After reboot, verify the new firmware version is installed
