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
The ZXR10 1800-2S before v3.00.40 incorrectly restricts access to a resource from an unauthorized actor, resulting in ordinary users being able to download configuration files to steal information like administrator accounts and passwords.

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 · moderate confidence

The ZXR10 1800-2S has an authorization bypass vulnerability where regular (non-privileged) users can access and download configuration files that contain sensitive information including administrator account credentials and passwords, due to improper access control restrictions in versions before v3.00.40.

MitigationUpgrade the ZXR10 1800-2S firmware to version v3.00.40 or later to implement proper access controls and prevent unauthorized configuration file downloads.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Identify the router model and firmware version
    Log into the ZXR10 router web interface or CLI and locate the system information or firmware version (typically under Status > System, or via 'show version' command)
    Affected if The device model is ZXR10 1800-2S, 2800-4, 3800-8, or 160 and the firmware version is less than 3.00.40
  2. Verify configuration file download is accessible
    Log in with a non-privileged (regular) user account and attempt to access the configuration file download feature in the web interface or via the backup/restore configuration function
    Affected if Non-privileged users can access and download the configuration file without requiring elevated privileges
  3. Check if configuration contains sensitive credentials
    Open the downloaded configuration file and search for plaintext passwords, username entries, or administrator account credentials
    Affected if The configuration file contains administrator usernames and passwords in plaintext

If the device runs firmware version below 3.00.40 AND non-privileged users can download configuration files containing plaintext credentials, the environment is affected by CVE-2017-10930.

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.

Upgrade available Upgrade to 3.00.40 or later
Fixed in 3.00.40
Interim mitigation

Upgrade the ZXR10 1800-2S firmware to version v3.00.40 or later to implement proper access controls and prevent unauthorized configuration file downloads.

Recommended fix High confidence

Firmware version 3.00.40 or later

  1. 1. Identify the current firmware version of the ZXR10 device by accessing the web management interface or CLI
  2. 2. If the firmware version is below 3.00.40, download the firmware version 3.00.40 or later from the official ZTE support portal (support.zte.com.cn)
  3. 3. Upload the new firmware through the device's web management interface under System > Firmware Upgrade, or via CLI using the firmware upgrade command
  4. 4. After upgrade, verify the new firmware version is 3.00.40 or higher
  5. 5. Confirm that the vulnerability is remediated by verifying that ordinary users can no longer access configuration files containing administrator credentials
