CVE-2025-5710 is a critical SQL Injection vulnerability identified in version 1.0 of the code-projects Real Estate Property Management System. The vulnerability exists in the /Admin/InsertState.php file, specifically in the handling of the txtStateName parameter. An attacker can manipulate this parameter to inject malicious SQL code, which the application then executes on the backend database. This flaw allows an unauthenticated remote attacker to execute arbitrary SQL commands without any user interaction or privileges. The vulnerability arises due to insufficient input validation or improper sanitization of user-supplied data before incorporating it into SQL queries. Exploiting this vulnerability could enable attackers to read, modify, or delete sensitive data stored in the database, potentially leading to data breaches, unauthorized data manipulation, or even full system compromise depending on the database permissions. Although no public exploits have been observed in the wild yet, the exploit details have been disclosed publicly, increasing the risk of exploitation. The CVSS 4.0 base score is 6.9 (medium severity), reflecting the network attack vector, no required privileges or user interaction, but limited impact on confidentiality, integrity, and availability (low impact on each). The vulnerability does not require authentication and can be triggered remotely, making it a significant risk for exposed installations of this software. The lack of available patches or mitigations from the vendor further exacerbates the threat landscape for affected users.

For European organizations using the code-projects Real Estate Property Management System version 1.0, this vulnerability poses a substantial risk to the confidentiality and integrity of their real estate data. Given that real estate management systems often contain sensitive personal information, financial data, and contractual documents, exploitation could lead to data breaches violating GDPR regulations, resulting in legal penalties and reputational damage. Attackers could manipulate property listings, client records, or transaction histories, undermining business operations and trust. Additionally, unauthorized database access could facilitate lateral movement within the organization's network, potentially exposing other critical systems. The remote and unauthenticated nature of the attack vector increases the likelihood of exploitation, especially if the system is accessible from the internet without proper network segmentation or firewall protections. The medium CVSS score suggests moderate impact, but the critical classification by the vendor indicates that the real-world consequences could be severe if exploited in targeted attacks. European real estate firms, property managers, and related service providers using this software are at risk of operational disruption and compliance violations.

1. Immediate mitigation should include restricting external network access to the affected Real Estate Property Management System, especially the /Admin/InsertState.php endpoint, via firewalls or VPNs. 2. Implement web application firewalls (WAFs) with custom rules to detect and block SQL injection payloads targeting the txtStateName parameter. 3. Conduct thorough input validation and sanitization on all user-supplied data, particularly the txtStateName field, using parameterized queries or prepared statements to prevent SQL injection. 4. If source code access is available, refactor the vulnerable code to use secure database access methods and validate inputs strictly. 5. Monitor logs for suspicious activity related to SQL injection attempts and unusual database queries. 6. Engage with the vendor or community to obtain or develop patches or updates addressing this vulnerability. 7. Perform regular security assessments and penetration testing on the application to identify and remediate similar vulnerabilities. 8. Educate system administrators and developers about secure coding practices and the risks of SQL injection. 9. As a longer-term measure, consider migrating to more secure and actively maintained property management solutions with robust security track records.
