CVE-2015-20117: RealtyScript 4.0.2 Cross-Site Request Forgery Unauthorized User Creation

Next Click Ventures RealtyScript 4.0.2 contains a cross-site request forgery vulnerability that allows unauthenticated attackers to create unauthorized user accounts and administrative users by crafting malicious forms. Attackers can submit hidden form data to /admin/addusers.php and /admin/editadmins.php endpoints to register new users with arbitrary credentials and escalate privileges to SUPERUSER level.

Security readout for executives and security teams

Plain-English summary

RealtyScript 4.0.2 has a CSRF flaw that can allow unauthorized creation of regular and administrative users. For organizations still running this older real-estate script, the main business risk is account takeover through new privileged accounts. No source in the bundle confirms active exploitation, but public exploit documentation exists.

Executive priority

Prioritize if RealtyScript 4.0.2 is internet-facing or used for business operations. The practical concern is unauthorized privileged account creation. If the product is not present, no action is needed beyond documenting non-exposure.

Technical view

CVE-2015-20117 is reported as CWE-352 in Next Click Ventures RealtyScript 4.0.2. The vulnerability affects user and administrator creation workflows, including administrative endpoints, and can allow arbitrary credentials and SUPERUSER-level accounts. The CVSS v4.0 score is 6.9, with network access and low attack complexity listed.

Likely exposure

Exposure is likely limited to organizations still operating RealtyScript 4.0.2, especially internet-facing deployments. The product appears old, so unmanaged legacy sites are the main concern. The provided sources do not identify other affected versions or hosted service exposure.

Exploitation context

The bundle includes Exploit-DB and Zero Science Lab references, so public exploit information exists. CISA KEV is not indicated, and the provided sources do not state active exploitation. Treat this as a legacy web-app risk with elevated impact if administrative account creation is reachable.

Researcher notes

Evidence comes from CVE, VulnCheck, Zero Science Lab, and Exploit-DB references. The record names only RealtyScript 4.0.2. No patch details are provided in the bundle. Avoid assuming broader version impact without vendor confirmation.

Mitigation direction

  • Confirm whether RealtyScript 4.0.2 is in use anywhere.
  • Check vendor or maintainer guidance for fixed versions or supported migration paths.
  • Restrict public access to administrative paths until resolved.
  • Remove or retire unsupported RealtyScript deployments where possible.
  • Review and remove unauthorized user or administrator accounts.

Validation and detection

  • Inventory web applications for RealtyScript 4.0.2 indicators.
  • Check whether admin user-management pages are internet-accessible.
  • Review application logs for unexpected user or admin creation activity.
  • Audit current SUPERUSER and administrator accounts for legitimacy.
  • Validate CSRF protections only in an authorized test environment.
