Security readout for executives and security teams
Plain-English summary
RealtyScript 4.0.2 has multiple unauthenticated SQL injection flaws. A remote attacker could query database contents indirectly through timing behavior. For organizations still running this real-estate application, the main business risk is exposure of sensitive property, customer, account, or operational data stored in its database.
Executive priority
Prioritize if RealtyScript 4.0.2 is internet-facing or stores customer, account, or transaction data. The issue is high severity, unauthenticated, and has public exploit material. If the product is not present, no action is needed beyond documenting that determination.
Technical view
CVE-2015-20120 affects Next Click Ventures RealtyScript 4.0.2. The issue is CWE-89: multiple time-based blind SQL injection vulnerabilities in application parameters. The CVSS 4.0 score is 8.8, with network attack vector, low complexity, no privileges, and no user interaction required. Sources indicate database extraction is possible via timing inference.
Likely exposure
Exposure is limited to deployments of RealtyScript 4.0.2 reachable by attackers, especially internet-facing instances. The source bundle does not identify other affected versions or CPEs. Organizations should verify whether RealtyScript is deployed, externally accessible, and connected to sensitive databases.
Exploitation context
Public exploit information exists through ExploitDB and third-party advisories. The provided sources do not show CISA KEV listing or confirmed active exploitation. Because exploitation is unauthenticated and network-based, any exposed legacy deployment should be treated as a credible target.
Researcher notes
Evidence supports multiple time-based blind SQL injection flaws in RealtyScript 4.0.2, with public exploit/advisory references. The bundle does not name an official patch, affected version range beyond 4.0.2, or active exploitation. Avoid assuming broader product impact without direct verification.
Mitigation direction
- Inventory systems for RealtyScript 4.0.2 deployments.
- Restrict public access to any affected RealtyScript instance.
- Check vendor or maintainer guidance for updates or replacement options.
- Back up and review databases connected to affected applications.
- Consider retiring unsupported or internet-facing legacy RealtyScript deployments.
Validation and detection
- Confirm the installed RealtyScript version from application files or admin records.
- Identify whether the application is internet-facing or reachable by untrusted users.
- Review web and database logs for suspicious parameter probing or timing anomalies.
- Check whether sensitive data is stored in the connected database.
- Validate remediation through authorized, non-destructive security testing.

Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')
Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
