CVE-2025-4265 is a SQL Injection vulnerability identified in version 1.0 of the PHPGurukul Emergency Ambulance Hiring Portal, specifically affecting the /admin/contact-us.php file. The vulnerability arises from improper sanitization or validation of the 'mobnum' parameter, which is susceptible to malicious input that can alter the intended SQL query logic. This allows an unauthenticated remote attacker to inject arbitrary SQL commands, potentially leading to unauthorized data access, data modification, or disruption of the backend database. The vulnerability does not require any user interaction or authentication, increasing its risk profile. Although the CVSS 4.0 base score is 6.9, categorized as medium severity, the exploitability is high due to network accessibility and lack of required privileges. The vulnerability affects an administrative interface, which may expose sensitive operational data or allow attackers to manipulate critical backend information. No patches or fixes have been published yet, and while no known exploits are currently active in the wild, public disclosure of the exploit code increases the likelihood of exploitation attempts. Other parameters may also be vulnerable, indicating a broader input validation issue within the application. The portal is designed for emergency ambulance hiring, implying that disruption or data compromise could impact emergency response services relying on this system.

For European organizations using the PHPGurukul Emergency Ambulance Hiring Portal, this vulnerability poses significant risks. Compromise of the portal could lead to unauthorized access to sensitive personal data of patients or clients, manipulation of ambulance dispatch information, or denial of service affecting emergency response times. Given the critical nature of emergency medical services, any disruption could have severe consequences on public health and safety. Additionally, data breaches involving personal health information would invoke strict regulatory scrutiny under GDPR, potentially resulting in heavy fines and reputational damage. The medium CVSS score may underestimate the operational impact in this context, as availability and integrity of emergency services are paramount. Organizations relying on this software must consider the risk of targeted attacks aiming to disrupt emergency healthcare infrastructure or steal sensitive data. The lack of authentication requirement for exploitation further increases the threat surface, enabling remote attackers to launch attacks without prior access.

Immediate mitigation steps include implementing strict input validation and parameterized queries or prepared statements in the affected /admin/contact-us.php script to prevent SQL injection. Organizations should conduct a thorough code review of all input handling in the portal, especially parameters related to administrative functions, to identify and remediate similar vulnerabilities. If possible, restrict network access to the administrative interface using firewalls or VPNs to limit exposure. Monitoring and logging of database queries and application logs should be enhanced to detect suspicious activities indicative of injection attempts. Since no official patch is available, organizations should consider isolating or temporarily disabling the vulnerable module until a secure update is released. Additionally, applying web application firewalls (WAF) with SQL injection detection rules can provide a compensating control. Regular backups of the database should be maintained to enable recovery in case of data tampering. Finally, organizations should stay informed about updates from the vendor or security advisories to apply patches promptly once available.
