Security readout for executives and security teams
Plain-English summary
RealtyScript 4.0.2 has a stored cross-site scripting flaw in its admin page editor. An authenticated attacker can save malicious HTML or iframe content that later runs in another user’s browser when the affected page is viewed. This is not listed in CISA KEV, but public exploit material exists.
Executive priority
Treat this as a targeted application risk, not an internet-wide emergency. Prioritize if RealtyScript 4.0.2 is used for public-facing property sites or if multiple users can access the admin console. Confirm deployment status first, then restrict admin exposure and seek vendor guidance.
Technical view
CVE-2015-20119 affects Next Click Ventures RealtyScript 4.0.2. The pages.php admin interface does not adequately neutralize input in the text parameter for add-page actions, enabling stored XSS. CVSS 3.1 is 6.4 with low complexity, low privileges required, changed scope, and low confidentiality and integrity impact.
Likely exposure
Exposure is limited to organizations running RealtyScript 4.0.2, especially where authenticated access to the admin interface is available to untrusted or weakly controlled users. Internet-facing admin panels increase operational risk. The provided sources do not identify other affected versions.
Exploitation context
The vulnerability requires authenticated access, but exploit details are publicly referenced by ExploitDB and advisories. The attack impact is browser-side execution of stored content for users viewing affected pages. There is no cited evidence of active exploitation or CISA KEV inclusion.
Researcher notes
Sources consistently describe stored XSS through the text parameter in pages.php for RealtyScript 4.0.2. Public exploit material exists, but the bundle does not show active exploitation, patched versions, or broad product impact. Avoid assuming newer or older versions are affected without vendor confirmation.
Mitigation direction
- Identify whether RealtyScript 4.0.2 is deployed.
- Restrict access to RealtyScript administrative interfaces.
- Review vendor or maintainer guidance for updates or fixes.
- Remove suspicious stored page content from affected RealtyScript pages.
- Limit admin accounts to trusted users only.
Validation and detection
- Inventory RealtyScript installations and confirm version 4.0.2 exposure.
- Check whether pages.php admin functionality is reachable.
- Review page content for unexpected HTML or iframe elements.
- Audit admin account activity for unauthorized page changes.
- Monitor browser-side security reports for XSS indicators.

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.
