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
There is a SQL injection vulnerability in some ZTE mobile internet products. Due to insufficient input validation of SMS interface parameter, an authenticated attacker could use the vulnerability to execute SQL injection and cause information leak.

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

SQL injection vulnerability in ZTE mobile internet products stemming from insufficient input validation on SMS interface parameters. An authenticated attacker can inject malicious SQL queries through these parameters to extract sensitive information from the database.

MitigationImplement proper input validation and use parameterized queries (prepared statements) for all SMS interface parameters. Additionally, apply least-privilege principles to database accounts used by the SMS interface to limit potential information exposure.

Verify against the referenced sources before acting — the references below are authoritative for this CVE, this summary is not.

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 ZTE device model
    Access the device web interface or check the device label to confirm the model number is MF833U1 or MF286R
    Affected if The device model is not MF833U1 or MF286R, then it is not affected by this specific CVE
  2. Check the installed firmware version
    Log into the device administration panel and navigate to the firmware or status page to view the current firmware version. Compare this against the affected versions: bd_mf833u1v1.0.0b01 for MF833U1 or cr_lvwrgbmf286rv1.0.0b04 for MF286R
    Affected if The installed firmware exactly matches one of the affected versions listed in the CVE, indicating the device may be vulnerable
  3. Determine if SMS interface is accessible
    Check if the SMS messaging feature is enabled on the device. This can typically be found in the device settings under SMS or messaging configuration, or by attempting to access the SMS-related web endpoints if known
    Affected if The SMS interface is disabled or not present, the SQL injection cannot be exploited through this vector
  4. Verify authentication status for SMS features
    Confirm whether default credentials have been changed and whether remote management or SMS API endpoints are accessible without additional authentication barriers
    Affected if The device requires valid authentication credentials to access SMS functionality, the attacker would need valid credentials to exploit this SQL injection

A device is affected if it is a ZTE MF833U1 or MF286R model running the exact firmware versions bd_mf833u1v1.0.0b01 or cr_lvwrgbmf286rv1.0.0b04 respectively, with the SMS interface enabled and accessible to an authenticated attacker.
