CVE-2026-44409
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 · uneditedThere is an an information disclosure vulnerability in ZTE MU5250. Due to improper configuration of the access control mechanism, attackers can obtain information without authorization, causing the risk of information disclosure.
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.
dbcve analysis · low confidenceZTE MU5250 contains an information disclosure vulnerability stemming from improper access control configuration. Attackers can obtain sensitive information without proper authorization due to this misconfiguration, which allows unauthorized access to potentially sensitive device data or management interfaces.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify the device modelAccess the device's management interface or check the device label/web interface to confirm it is a ZTE MU5250. This can often be done by visiting the device's IP address in a web browser or checking the administrative panel.Affected if The device is confirmed to be a ZTE MU5250
-
Determine the installed firmware versionLog into the device's web management interface and navigate to the System, Status, or About section to view the firmware version. Alternatively, check the device's command-line interface if available, or review firmware upgrade documentation.Affected if The firmware version is exactly 1.0.0b27
-
Test management interface accessibility without credentialsOpen a web browser and navigate directly to the device's management interface IP address without providing any login credentials. Observe whether the interface loads or returns sensitive information without requiring authentication.Affected if The management interface or login page loads and displays sensitive information without requiring any authentication credentials
-
Test API endpoints for unauthenticated accessUse a tool like curl or a web browser to send requests to common API endpoints on the device (such as /api/, /cgi-bin/, or similar endpoints) without including any authentication tokens or headers. Observe if the device returns sensitive data or configuration details.Affected if API endpoints respond with sensitive information, device configuration, or administrative data without requiring authentication
You are affected if the device is a ZTE MU5250 running firmware version 1.0.0b27 AND the management interface or API endpoints are accessible without any authentication, exposing sensitive information.
Generated from the published advisory. Verify against your own configuration.
Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataProperly configure and enforce access control mechanisms on the ZTE MU5250 device, ensuring all sensitive endpoints require appropriate authentication and are not exposed to unauthorized network access.
