CVE-2025-6570 is a SQL Injection vulnerability identified in version 4.0 of the PHPGurukul Hospital Management System, specifically within the /doctor/search.php file. The vulnerability arises from improper sanitization or validation of the 'searchdata' parameter, which is used in SQL queries. An attacker can manipulate this parameter remotely without authentication or user interaction to inject malicious SQL code. This can lead to unauthorized access to the backend database, potentially allowing the attacker to read, modify, or delete sensitive patient and hospital data. The vulnerability is classified as medium severity with a CVSS 4.0 score of 5.3, reflecting a network attack vector, low attack complexity, no privileges required, and no user interaction needed. The impact on confidentiality, integrity, and availability is limited but present, as the vulnerability allows partial control over database queries. No public exploits have been reported yet, but the exploit details have been disclosed, increasing the risk of exploitation. The lack of available patches or updates from the vendor at this time further elevates the risk for organizations using this specific version of the software.

For European healthcare organizations using PHPGurukul Hospital Management System 4.0, this vulnerability poses a significant risk to patient data confidentiality and system integrity. Successful exploitation could lead to unauthorized disclosure of sensitive medical records, manipulation of patient information, or disruption of hospital operations. Given the critical nature of healthcare data and strict regulatory requirements such as GDPR, any data breach could result in severe legal and financial consequences. Additionally, compromised hospital management systems could impact patient care delivery and trust in healthcare providers. The medium severity rating suggests that while the vulnerability is exploitable remotely without authentication, the impact is somewhat limited by the scope of affected functionality and the level of control an attacker gains. However, the public disclosure of the exploit increases the urgency for mitigation to prevent potential attacks.

Organizations should immediately audit their use of PHPGurukul Hospital Management System 4.0 and identify any instances of the vulnerable /doctor/search.php endpoint. In the absence of an official patch, it is critical to implement input validation and parameterized queries or prepared statements to sanitize the 'searchdata' input and prevent SQL injection. Web application firewalls (WAFs) should be configured with specific rules to detect and block SQL injection attempts targeting this parameter. Network segmentation and strict access controls should be enforced to limit exposure of the hospital management system to untrusted networks. Regular monitoring of logs for suspicious query patterns related to 'searchdata' can help detect exploitation attempts early. Organizations should also engage with the vendor for updates and plan for timely patching once available. Finally, conducting security awareness training for developers and administrators on secure coding practices and vulnerability management is recommended to prevent similar issues.
