CVE-2025-5610 is a SQL Injection vulnerability identified in version 1.0 of the CodeAstro Real Estate Management System, specifically within the /submitpropertydelete.php file. The vulnerability arises from improper sanitization or validation of the 'ID' parameter, which an attacker can manipulate to inject malicious SQL code. This flaw allows remote attackers to execute unauthorized SQL commands on the backend database without requiring authentication or user interaction. The vulnerability is classified as medium severity with a CVSS 4.0 base score of 5.3, reflecting that it is remotely exploitable with low attack complexity and no privileges or user interaction needed, but with limited impact on confidentiality, integrity, and availability. Exploiting this vulnerability could enable attackers to read, modify, or delete database records related to property listings or user data, potentially leading to data leakage, unauthorized data manipulation, or disruption of service. Although no public exploits are currently known in the wild, the disclosure of the vulnerability increases the risk of exploitation. The lack of available patches or mitigations from the vendor further elevates the urgency for organizations to implement compensating controls.

For European organizations using the CodeAstro Real Estate Management System, this vulnerability poses a significant risk to the confidentiality and integrity of sensitive real estate data, including property details and client information. Successful exploitation could lead to unauthorized data disclosure, data tampering, or deletion, undermining trust and potentially violating data protection regulations such as the GDPR. The disruption of real estate management operations could also impact business continuity and client services. Given the remote exploitability without authentication, attackers could target these systems from anywhere, increasing the threat landscape. The medium severity rating suggests moderate impact, but the critical nature of real estate data and regulatory environment in Europe amplifies the consequences of a breach.

Since no official patches are currently available, European organizations should immediately implement the following mitigations: 1) Employ Web Application Firewalls (WAFs) with custom rules to detect and block SQL injection attempts targeting the /submitpropertydelete.php endpoint and the 'ID' parameter. 2) Conduct thorough input validation and sanitization on all user-supplied data, especially the 'ID' parameter, using parameterized queries or prepared statements if possible within the application code. 3) Restrict database user permissions to the minimum necessary, preventing the application from executing destructive SQL commands. 4) Monitor logs for unusual database queries or repeated access attempts to the vulnerable endpoint. 5) Isolate the affected system within the network to limit exposure and consider temporary disabling of the vulnerable functionality if feasible. 6) Engage with the vendor for updates or patches and plan for an immediate upgrade once available. 7) Conduct security awareness training for administrators to recognize and respond to potential exploitation attempts.
