CVE-2015-20120
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 · uneditedNext Click Ventures RealtyScript 4.0.2 contains multiple time-based blind SQL injection vulnerabilities that allow unauthenticated attackers to extract database information by injecting SQL code into application parameters. Attackers can craft requests with time-delay payloads to infer database contents character by character based on response timing differences.
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 confidenceNext Click Ventures RealtyScript 4.0.2 contains multiple time-based blind SQL injection vulnerabilities allowing unauthenticated attackers to inject SQL code into application parameters. Attackers infer database contents character-by-character by crafting requests with time-delay payloads and measuring response timing differences.

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 RealtyScript installationLocate the web application directory or check HTTP response headers for 'RealtyScript' or 'Nextclickventures' identifiers. Inspect the website's source code footer for 'Powered by RealtyScript' or similar branding.Affected if The application is identified as Nextclickventures RealtyScript version 4.0.2
-
Confirm exact version numberCheck application files for version.txt, about.php, or admin configuration panels that display the software version. Compare against the affected version 4.0.2 specifically.Affected if Installed version is exactly 4.0.2
-
Determine if application is internet-facingVerify whether the web server hosting RealtyScript is accessible from external networks. Check firewall rules, web server bindings, and network accessibility.Affected if The application is publicly accessible without authentication requirements
-
Identify exposed application parametersReview web application logs or capture HTTP requests to identify parameters passed to the application (GET/POST requests). Common areas include search fields, property ID parameters, and navigation inputs.Affected if User-controllable parameters are passed to the application without apparent input sanitization or parameterized queries
-
Assess authentication statusDetermine if the SQL injection points are reachable without authentication. Test accessing application pages and parameter endpoints without providing login credentials.Affected if Unauthenticated access to vulnerable parameters is possible
The environment is affected if Nextclickventures RealtyScript version 4.0.2 is installed and its application parameters are accessible without authentication, as the SQL injection can be exploited remotely without credentials.

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 dataRemediate by replacing dynamic SQL queries with parameterized queries/prepared statements across all application parameters, implementing strict input validation, and conducting thorough penetration testing to verify all injection points are eliminated.
