CVE-2025-6909 is a SQL Injection vulnerability identified in version 1.0 of the PHPGurukul Old Age Home Management System, specifically within the /admin/add-scdetails.php file. The vulnerability arises from improper sanitization or validation of the 'emeradd' parameter, which is used in SQL queries. An attacker can remotely manipulate this parameter to inject malicious SQL code, potentially allowing unauthorized access to the backend database. This can lead to unauthorized data retrieval, modification, or deletion, depending on the database permissions and structure. The vulnerability does not require user interaction or authentication, making it easier to exploit remotely. The CVSS 4.0 score is 5.3 (medium severity), reflecting that while the attack vector is network-based and does not require authentication, the impact on confidentiality, integrity, and availability is limited to low levels. The exploit has been publicly disclosed, increasing the risk of exploitation, although no known active exploits have been reported in the wild yet. The vulnerability affects only version 1.0 of the product, which is a niche application designed for managing old age home operations, likely including sensitive personal and medical data of residents.

For European organizations using the PHPGurukul Old Age Home Management System version 1.0, this vulnerability poses a significant risk to the confidentiality and integrity of sensitive resident data, including personal identification and potentially health-related information. Exploitation could lead to unauthorized data disclosure or manipulation, violating data protection regulations such as GDPR. Additionally, data integrity compromise could disrupt operational workflows, impacting care delivery. Although the availability impact is considered low, any disruption in system functionality could affect administrative efficiency. The medium severity score suggests that while the vulnerability is exploitable remotely without authentication, the overall damage potential is somewhat limited, possibly due to restricted database permissions or limited functionality exposure. However, the public disclosure of the exploit code increases the urgency for mitigation to prevent potential targeted attacks. Organizations in Europe must consider the regulatory implications of data breaches and the reputational damage associated with compromised elder care systems.

1. Immediate application of patches or updates from PHPGurukul if available; if no official patch exists, implement manual input validation and parameterized queries (prepared statements) for the 'emeradd' parameter to prevent SQL injection. 2. Employ Web Application Firewalls (WAFs) configured to detect and block SQL injection attempts targeting the vulnerable endpoint. 3. Conduct thorough code reviews and security testing of the affected module to identify and remediate similar injection points. 4. Restrict database user permissions to the minimum necessary to limit the impact of any successful injection. 5. Monitor logs for unusual query patterns or repeated access attempts to /admin/add-scdetails.php, enabling early detection of exploitation attempts. 6. If feasible, isolate the vulnerable system from direct internet exposure or restrict access via VPN or IP whitelisting to reduce attack surface. 7. Educate administrators and developers about secure coding practices and the importance of input sanitization to prevent future vulnerabilities.
