CVE-2025-7176 is a critical SQL Injection vulnerability identified in version 1.0 of the PHPGurukul Hospital Management System, specifically within the file view-medhistory.php. The vulnerability arises from improper sanitization or validation of the 'viewid' parameter, which is used to query the database. An attacker can manipulate this parameter to inject malicious SQL code, potentially allowing unauthorized access to sensitive patient medical history data or modification of database contents. The attack vector is remote and does not require any authentication or user interaction, making exploitation straightforward. Although the CVSS score is 6.9 (medium severity), the vulnerability's characteristics—remote, no authentication, and direct database manipulation—suggest a significant risk. The exploit has been publicly disclosed, increasing the likelihood of exploitation by threat actors. The vulnerability affects the confidentiality, integrity, and availability of the hospital management system's data, potentially leading to data breaches, data tampering, or denial of service. Given the critical nature of healthcare data, this vulnerability poses a serious threat to affected organizations.

For European organizations, particularly hospitals and healthcare providers using PHPGurukul Hospital Management System 1.0, this vulnerability could lead to severe data breaches involving sensitive patient medical records. Such breaches would violate GDPR regulations, resulting in substantial legal and financial penalties. The integrity of patient data could be compromised, affecting clinical decisions and patient safety. Additionally, attackers could disrupt hospital operations by altering or deleting critical data, leading to availability issues. The reputational damage and loss of patient trust could be significant. Furthermore, healthcare infrastructure is often targeted by cybercriminals and nation-state actors, increasing the risk of exploitation. The public disclosure of the exploit further elevates the threat level, as opportunistic attackers may attempt to leverage this vulnerability in ransomware or data theft campaigns.

1. Immediate application of patches or updates from PHPGurukul once available is critical. In the absence of official patches, organizations should implement input validation and parameterized queries (prepared statements) to sanitize the 'viewid' parameter and 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 (including dynamic and static analysis) of the hospital management system to identify and remediate similar vulnerabilities. 4. Restrict database user privileges to the minimum necessary to limit the impact of potential exploitation. 5. Monitor logs for unusual database queries or access patterns indicative of exploitation attempts. 6. Educate IT and security teams about this vulnerability and ensure incident response plans include steps to address potential exploitation. 7. Consider network segmentation to isolate critical healthcare systems and limit exposure.
