CVE-2017-17414
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 · uneditedThis 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 NVBUPhaseStatus 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-4225.
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 confidenceA pre-authentication SQL injection vulnerability in Quest NetVault Backup 11.3.0.12 allows remote unauthenticated attackers to execute arbitrary code via the NVBUPhaseStatus Get method. The application fails to validate user-supplied input before using it in SQL query construction, enabling attackers to inject malicious SQL statements and execute code in the database context.

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 NetVault Backup installationLocate the NetVault Backup installation directory and check for the version file, typically found in the installation root folder or check the Windows registry under HKLM\SOFTWARE\Quest\NetVault Backup\CurrentVersion for the Version valueAffected if The installed version is exactly 11.3.0.12
-
Verify web service is runningCheck if the NetVault Backup web service (usually on port 8443 or 20031) is running and accessible by accessing the web interface URL (e.g., https://hostname:8443)Affected if The web interface is accessible without authentication and the service is running
-
Confirm NVBUPhaseStatus endpoint exposureAttempt to access the vulnerable endpoint by sending a GET request to the NVBUPhaseStatus method (typically at /cgi-bin/nvbuwebservices.exe) with a test parameterAffected if The endpoint responds and accepts parameters without requiring authentication
-
Check for signs of compromiseReview NetVault Backup database logs and web server logs for suspicious SQL syntax, unusual database queries, or evidence of unauthorized access patternsAffected if Log analysis reveals SQL injection patterns or unexpected database queries from external IP addresses
The environment is affected if Quest NetVault Backup version 11.3.0.12 is installed and the web service is exposed, making the pre-authentication SQL injection in the NVBUPhaseStatus method exploitable.

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 dataApply vendor patches for Quest NetVault Backup immediately. If no patch is available, restrict network access to the NetVault Backup service and implement WAF rules to detect and block SQL injection attempts as a temporary compensating control.
