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
Quest NetVault Backup NVBUDashboard SQL Injection Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of Quest NetVault Backup. Although authentication is required to exploit this vulnerability, the existing authentication mechanism can be bypassed. The specific flaw exists within the processing of NVBUDashboard JSON-RPC messages. The issue results from the lack of proper validation of a user-supplied string before using it to construct SQL queries. An attacker can leverage this vulnerability to execute code in the context of NETWORK SERVICE. Was ZDI-CAN-27809.

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

Quest NetVault Backup contains a SQL injection vulnerability in the NVBUDashboard JSON-RPC message processing function. The application fails to properly validate user-supplied input before using it in SQL query construction. Additionally, the authentication mechanism can be bypassed, allowing unauthenticated attackers to exploit the SQL injection and achieve remote code execution as the NETWORK SERVICE account.

MitigationApply the vendor patch when available; if no patch exists, implement parameterized queries/prepared statements for all database operations in the JSON-RPC handler and fix the authentication bypass logic.

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 NetVault Backup installation and version
    Locate the NetVault Backup installation directory and find the version information, typically in the main executable or a version file within the program folder
    Affected if NetVault Backup is installed and the version is below 14.0.2
  2. Verify NVBUDashboard service status
    Check if the NVBUDashboard service is running on the system, typically as a Windows service
    Affected if The NVBUDashboard service is installed and running
  3. Confirm JSON-RPC interface exposure
    Determine if the NVBUDashboard JSON-RPC interface is network-accessible, typically listening on a TCP port
    Affected if The JSON-RPC interface is exposed to the network or untrusted hosts
  4. Review authentication configuration
    Examine the NVBUDashboard authentication settings to determine if the authentication bypass is possible
    Affected if Authentication is configured in a way that allows bypass or uses default credentials
  5. Inspect logs for SQL injection indicators
    Search NVBUDashboard and database logs for suspicious SQL query patterns, unexpected SQL syntax, or anomalous database requests
    Affected if Logs contain unusual SQL statements or injection attempt signatures

The environment is affected if Quest NetVault Backup is installed with a version lower than 14.0.2 and the NVBUDashboard JSON-RPC interface is accessible, regardless of authentication status since bypass is possible.

Upgrade available Upgrade to 14.0.2 or later
Fixed in 14.0.2
Interim mitigation

Apply the vendor patch when available; if no patch exists, implement parameterized queries/prepared statements for all database operations in the JSON-RPC handler and fix the authentication bypass logic.

Recommended fix Moderate confidence

14.0.2

  1. 1. Obtain Quest NetVault Backup version 14.0.2 or later from the official Quest support portal at support.quest.com
  2. 2. Review the upgrade documentation and release notes for NetVault Backup 14.0.2
  3. 3. Ensure you have a complete backup of the NetVault Backup configuration and database
  4. 4. Schedule a maintenance window to minimize disruption
  5. 5. Stop the NetVault Backup services before performing the upgrade
  6. 6. Install NetVault Backup version 14.0.2 following the documented upgrade procedure
  7. 7. After installation, verify that the NVBUDashboard service is running correctly
  8. 8. Confirm the upgrade was successful by checking the NetVault Backup version in the web interface or CLI
Caveat Review release notes for any configuration or feature changes between your current version and 14.0.2
