CVE-2025-6309 is a SQL Injection vulnerability identified in version 1.0 of the PHPGurukul Emergency Ambulance Hiring Portal, specifically within the /admin/add-ambulance.php file. The vulnerability arises due to improper sanitization or validation of the 'ambregnum' parameter, which is used in SQL queries. An attacker can remotely manipulate this parameter to inject malicious SQL code, potentially altering the behavior of the database queries executed by the application. 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 without authentication, increasing the attack surface. Although the CVSS 4.0 score is 5.3 (medium severity), the presence of remote exploitability and lack of required authentication make this a significant risk. The vulnerability affects only version 1.0 of the product, and no official patches or mitigations have been published yet. No known exploits are currently observed in the wild, but public disclosure of the exploit code increases the likelihood of exploitation attempts. The Emergency Ambulance Hiring Portal is a specialized web application likely used by healthcare or emergency service providers to manage ambulance resources, making the confidentiality and integrity of the data critical for operational continuity and patient safety.

For European organizations, particularly those involved in healthcare, emergency services, or public safety, exploitation of this vulnerability could have severe consequences. Unauthorized access or manipulation of ambulance registration data could disrupt emergency response operations, delay critical medical assistance, or lead to misinformation in resource allocation. Data breaches could expose sensitive patient or operational data, violating GDPR and other data protection regulations, resulting in legal and financial repercussions. The integrity of emergency service records is paramount; any tampering could undermine trust in public health infrastructure. Additionally, attackers could leverage this vulnerability as a foothold to pivot into broader network segments, potentially compromising other critical systems. Given the portal's niche use, organizations relying on this specific software version are at direct risk, and the impact could extend to regional emergency coordination centers if the software is widely deployed.

Since no official patches are currently available, European organizations should implement immediate compensating controls. First, restrict access to the /admin/add-ambulance.php endpoint by IP whitelisting or VPN-only access to limit exposure. Implement Web Application Firewalls (WAFs) with custom rules to detect and block SQL injection patterns targeting the 'ambregnum' parameter. Conduct thorough input validation and sanitization on all user-supplied data, especially parameters interacting with the database. If possible, disable or remove the vulnerable functionality until a patch is released. Monitor application logs for unusual query patterns or repeated failed attempts indicative of exploitation. Engage with the vendor or community to obtain updates or patches and plan for prompt application once available. Additionally, perform regular database backups and ensure incident response plans are updated to address potential data integrity incidents stemming from this vulnerability.
