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
This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Quest NetVault Backup 11.3.0.12. Authentication is not required to exploit this vulnerability. The specific flaw exists within the handling of NVBUScheduleSet Get method requests. 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 the underlying database. Was ZDI-CAN-4235.

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 · high confidence

SQL injection vulnerability in the NVBUScheduleSet Get method of Quest NetVault Backup 11.3.0.12 allows remote unauthenticated attackers to execute arbitrary code by supplying malicious input that is not validated before being used in SQL query construction.

MitigationApply vendor patch immediately. If no patch is available, restrict network exposure of the NetVault Backup service and deploy WAF/IPS rules to detect SQL injection attack patterns in HTTP requests.

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. Verify NetVault Backup installation
    Check for Quest NetVault Backup installation by looking in program directories (typically C:\Program Files\Quest\NetVault Backup or /opt/quest/netvault) and check the version information in the main application or via command: nvtsan -version or through the web interface login page
    Affected if Quest NetVault Backup is not installed or version differs from 11.3.0.12
  2. Confirm exact version number
    Locate the exact version file or use the application's About/Version information panel. Common paths: Installation directory or registry entry HKLM\SOFTWARE\Quest\NetVault\Backup\CurrentVersion
    Affected if Version is anything other than 11.3.0.12 exactly
  3. Determine web interface exposure
    Check if the NetVault Backup web service (default port 8443 or 8080) is listening and accessible from network. Run netstat or check firewall rules to determine if port 8443/8080 is exposed to untrusted networks
    Affected if Web interface is exposed to untrusted networks (internet or less trusted LAN segments)
  4. Identify vulnerable endpoint accessibility
    Verify the NVBUScheduleSet API endpoint exists and is reachable via HTTP to the web interface. This is typically at /cgi-bin/nvbackup.exe/NVBUScheduleSet or similar CGI path under the web service
    Affected if NVBUScheduleSet endpoint is accessible without authentication

Affected if running exactly version 11.3.0.12 of Quest NetVault Backup with the web interface and NVBUScheduleSet endpoint exposed to untrusted access
