CVE-2026-14743: SQL Injection in Real State Services 1.0 – Vulnerability Overview & Remediation

Technical summary

CVE-2026-14743 is a remote SQL injection flaw arising from insufficient input validation on the 'loc' parameter within /normalHomeSale.php. The application fails to sanitize user-supplied input before passing it to a database query, allowing attackers to execute arbitrary SQL statements. The vulnerability is classified under CWE-74 (Improper Neutralization of Special Elements in Output) and CWE-89 (SQL Injection), reflecting both the root cause (unsanitized input) and the attack mechanism. The CVSS 3.1 vector (AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L) indicates network-based exploitation with low complexity, no privilege requirements, and impacts to confidentiality, integrity, and availability.

Business impact

Successful exploitation enables attackers to read, modify, or delete sensitive data stored in the application's database, including customer property information, transaction records, or personal details. This can lead to data breaches, regulatory compliance violations (GDPR, CCPA, etc.), reputational damage, financial fraud, and potential business interruption if the database is corrupted or unavailable. Organizations relying on Real State Services 1.0 face immediate operational and legal risk.

Affected systems

The vulnerability impacts code-projects Real State Services version 1.0. All deployments of this specific version are affected, regardless of hosting environment (on-premises or cloud). Organizations should conduct an inventory of Real State Services installations and note their version numbers to determine exposure scope.

Exploitability

Exploitability is high. The attack is trivial to execute—attackers need only craft a malicious HTTP request with SQL syntax in the 'loc' parameter. No authentication, special privileges, or user interaction is required. The public availability of exploit code significantly lowers the barrier to entry for both skilled and opportunistic attackers. Active exploitation in the wild is a real possibility.

Remediation

Immediate action is required. Organizations must identify all instances of Real State Services 1.0 in their environment. The vendor should release a patched version; until then, apply input validation and parameterized queries to sanitize the 'loc' parameter, implement Web Application Firewall (WAF) rules to block SQL injection patterns, restrict database account permissions using principle of least privilege, and consider temporarily disabling the /normalHomeSale.php endpoint if business operations permit. Verify the vendor's advisory for an official patch release timeline.

Patch guidance

Contact code-projects for a security update addressing CVE-2026-14743. If a patch version is released, test it thoroughly in a non-production environment before deployment. Monitor the vendor's security advisories and apply patches as soon as they are validated. In the interim, implement compensating controls such as WAF rules and input validation at the application layer.

Detection guidance

Monitor web server and application logs for suspicious requests to /normalHomeSale.php containing SQL syntax in the 'loc' parameter (e.g., single quotes, SQL keywords like UNION, SELECT, OR 1=1). Use Web Application Firewall signatures to detect SQL injection attempts. Database activity monitoring may reveal unusual query patterns or unauthorized data access. Network segmentation and access controls can limit attacker reach. Implement rate limiting on the affected endpoint to disrupt brute-force exploitation attempts.

Why prioritize this

This vulnerability warrants immediate remediation. The combination of high CVSS score (7.3), publicly available exploit, no authentication requirement, and direct database access justifies critical priority. Organizations running Real State Services 1.0 should treat this as a security emergency and allocate resources to patching or mitigation without delay.

Risk score, explained

The CVSS 3.1 score of 7.3 (HIGH) reflects a network-accessible SQL injection with low attack complexity and no privilege or user interaction barriers. The impact metrics (C:L/I:L/A:L) indicate partial compromise of confidentiality, integrity, and availability. The public exploit and active threat landscape push practical risk higher than the baseline CVSS score alone suggests—this should be treated as a critical vulnerability in operational environments.
