CVE-2017-17652
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 NVBUBackup Count 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-4238.
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 confidenceSQL injection vulnerability in Quest NetVault Backup 11.3.0.12's NVBUBackup Count method allows unauthenticated remote attackers to execute arbitrary code via specially crafted requests containing malicious SQL in user-supplied strings that are not validated before query construction.

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 Quest NetVault Backup installation on the system. Common paths include C:\Program Files\Quest\NetVault Backup\ or /opt/netvault/ on Linux. Check for nvbackup.exe or equivalent binaries.Affected if NetVault Backup software is installed on the system
-
Determine installed versionOpen the NetVault Backup web interface (typically port 8443 or 20031) and check the About/Version page, or run 'nvbackup -version' from the installation directory, or check the Windows Registry under HKLM\SOFTWARE\Quest\NetVault Backup\CurrentVersion.Affected if The installed version is exactly 11.3.0.12
-
Verify NVBUBackup Count service accessibilityCheck if the NetVault Backup web service/API endpoint is reachable. This is typically exposed via the NetVault Backup Web Server service. Attempt to access the URL path containing 'NVBUBackup' or the Count method if known.Affected if The NetVault Backup web interface/API is accessible from the network
-
Assess network exposureReview firewall rules, network ACLs, and service binding configurations to determine if the NetVault Backup web service (port 8443 or 20031) is bound to external or untrusted network interfaces.Affected if The NetVault Backup service is exposed to untrusted or external networks without proper network segmentation
The environment is affected if Quest NetVault Backup version 11.3.0.12 is installed AND the web service/API interface containing the NVBUBackup Count method is network-accessible.

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 patch or update to a fixed version; if unavailable, restrict network exposure of the NetVault Backup service and implement input validation with parameterized queries as a compensating control.
