Security readout for executives and security teams
Plain-English summary
RealtyScript 4.0.2 has a stored cross-site scripting issue in the admin locations feature. Malicious JavaScript can be saved in a location name and later run in an administrator’s browser. This can expose admin sessions or allow unauthorized actions in the application context. Public exploit information exists, but the provided sources do not show active exploitation.
Executive priority
Prioritize remediation if RealtyScript 4.0.2 is internet-facing or used for active business operations. The risk is elevated because stored XSS can affect administrators and public exploit information is available. If the product is not deployed, no action is needed beyond documentation.
Technical view
CVE-2015-20118 is CWE-79 stored XSS affecting Next Click Ventures RealtyScript 4.0.2. The issue is tied to the location_name parameter in the admin locations interface at locations.php. The published CVSS 3.1 score is 7.2, high, with network attack vector and scope changed. Sources include third-party disclosure, ExploitDB, and VulnCheck.
Likely exposure
Exposure is likely limited to organizations still running RealtyScript 4.0.2, especially internet-accessible deployments with reachable administrative functionality. Evidence for other versions is not provided in the source bundle.
Exploitation context
A public ExploitDB entry and third-party advisory exist, so defenders should assume technical details are available. The source bundle does not include CISA KEV listing or other cited evidence of active exploitation in the wild.
Researcher notes
The CVE was published in 2026 for a 2015 disclosure. The provided evidence identifies only RealtyScript 4.0.2 and does not name a vendor patch. Treat exploit availability as public proof-of-concept availability, not confirmed active exploitation.
Mitigation direction
- Identify whether RealtyScript 4.0.2 is present in any environment.
- Check Next Click Ventures or product maintainer guidance for an official fix or upgrade path.
- Restrict administrative access to trusted networks and authenticated administrators.
- Review stored location records for unexpected script-like content.
- Apply compensating controls for input validation and output encoding where maintainable.
Validation and detection
- Inventory web applications and confirm RealtyScript version numbers.
- Verify whether admin locations functionality is accessible externally.
- Review application logs for suspicious location-management POST activity.
- Inspect stored location names for unexpected markup or script content.
- Confirm remediation by testing that saved location names render as harmless text.

Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')
Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
