CVE-2025-5705 is a SQL Injection vulnerability identified in version 1.0 of the code-projects Real Estate Property Management System, specifically within the /Admin/Property.php file. The vulnerability arises from improper sanitization or validation of the 'cmbCat' parameter, which is susceptible to malicious input manipulation. An attacker can exploit this flaw remotely without requiring authentication or user interaction, allowing them to inject arbitrary SQL commands into the backend database queries. This can lead to unauthorized data access, data modification, or potentially full compromise of the database server. The CVSS 4.0 base score is 6.9, indicating a medium severity level, with the vector highlighting no privileges or user interaction needed, and low impact on confidentiality, integrity, and availability. Although no known exploits have been reported in the wild yet, the public disclosure of the exploit code increases the risk of exploitation by threat actors. The vulnerability affects only version 1.0 of the product, which is a niche real estate management system used to handle property listings and administrative functions.

For European organizations using this Real Estate Property Management System, the SQL Injection vulnerability poses significant risks. Exploitation could lead to unauthorized access to sensitive property data, client information, and administrative records, potentially violating data protection regulations such as GDPR. Data integrity could be compromised, affecting business operations and trustworthiness. Additionally, attackers could leverage this vulnerability as a foothold to escalate privileges or move laterally within the network. Given the remote and unauthenticated nature of the exploit, attackers can operate stealthily and at scale. The impact is particularly critical for real estate firms handling large volumes of personal and financial data, as breaches could result in legal penalties and reputational damage.

Organizations should immediately assess their use of the code-projects Real Estate Property Management System version 1.0 and prioritize upgrading to a patched or newer version once available. In the absence of an official patch, implement strict input validation and parameterized queries or prepared statements to sanitize the 'cmbCat' parameter and any other user inputs. Employ Web Application Firewalls (WAFs) configured to detect and block SQL Injection patterns targeting the vulnerable endpoint. Conduct thorough code reviews and penetration testing focusing on SQL Injection vectors. Additionally, monitor logs for suspicious database query patterns and unauthorized access attempts. Restrict database user privileges to the minimum necessary to limit the impact of any successful injection. Finally, ensure regular backups of critical data to enable recovery in case of data corruption or loss.
