CVE-2025-5761 is a SQL Injection vulnerability identified in version 1.0 of the PHPGurukul BP Monitoring Management System, specifically within the /edit-family-member.php file. The vulnerability arises due to improper sanitization or validation of the 'memberage' parameter, which is directly used in SQL queries. An attacker can manipulate this parameter remotely to inject malicious SQL code, potentially altering the intended database queries. This could lead to unauthorized data access, data modification, or even deletion, depending on the database permissions and the nature of the injected payload. The vulnerability does not require user interaction and can be exploited remotely without authentication, increasing its risk profile. However, the CVSS 4.0 vector indicates that some privileges are required (PR:L), and the impact on confidentiality, integrity, and availability is limited (VC:L, VI:L, VA:L). The exploit has been publicly disclosed, but no known exploits in the wild have been reported yet. The absence of patches or mitigation links suggests that the vendor has not yet released an official fix, making timely mitigation critical. Given the critical classification by the source but a medium CVSS score of 5.3, this vulnerability represents a moderate risk that could escalate if exploited in targeted attacks, especially in environments where sensitive health data is processed.

For European organizations, especially those in healthcare or managing patient data, this vulnerability poses a significant risk. Exploitation could lead to unauthorized access to sensitive personal health information, violating GDPR regulations and potentially resulting in severe legal and financial penalties. The integrity of patient records could be compromised, leading to incorrect medical decisions or loss of trust. Availability impacts, while limited, could disrupt healthcare services if database integrity is affected. Given the remote exploitability without user interaction, attackers could automate attacks to extract or manipulate data at scale. Organizations using PHPGurukul BP Monitoring Management System 1.0 should consider the risk of data breaches and reputational damage. The medium severity score suggests that while the vulnerability is not the most critical, the sensitive nature of the data involved elevates its importance in the European context.

Immediate mitigation should include implementing input validation and parameterized queries or prepared statements to prevent SQL injection. Since no official patch is currently available, organizations should consider deploying Web Application Firewalls (WAFs) with custom rules to detect and block malicious payloads targeting the 'memberage' parameter. Conduct thorough code reviews and security testing of the affected module to identify and remediate similar vulnerabilities. Restrict database user permissions to the minimum necessary to limit the impact of any injection. Monitor logs for suspicious activities related to /edit-family-member.php and the 'memberage' parameter. Additionally, organizations should prepare incident response plans specific to potential data breaches involving this system and ensure compliance with GDPR breach notification requirements. Where possible, isolate or segment the affected system from critical networks until a patch or fix is applied.
