CVE-2025-4226 is a SQL Injection vulnerability identified in version 1.0 of the PHPGurukul/Campcodes Cyber Cafe Management System, specifically within the /add-computer.php file. The vulnerability arises due to improper sanitization or validation of user-supplied input parameters 'compname' and 'comploc', which are used in SQL queries without adequate protection. This flaw allows an unauthenticated remote attacker to inject malicious SQL code, potentially manipulating the backend database. The vulnerability is exploitable without any authentication or user interaction, increasing its risk profile. The CVSS 4.0 score is 6.9, categorized as medium severity, reflecting the network attack vector, low complexity, and no privileges or user interaction required. The impact on confidentiality, integrity, and availability is rated low individually, but combined they could allow unauthorized data access or modification, depending on the database schema and privileges. No known exploits are currently reported in the wild, and no official patches have been released yet. The public disclosure of the exploit details increases the risk of exploitation by threat actors. Given the nature of cyber cafe management systems, which typically handle user session data, billing, and computer usage logs, exploitation could lead to unauthorized data access, data tampering, or disruption of service.

For European organizations operating cyber cafes or similar public access computing environments using PHPGurukul Cyber Cafe Management System 1.0, this vulnerability poses a tangible risk. Exploitation could lead to unauthorized access to customer data, including potentially sensitive personal information, usage logs, or payment details, thereby violating GDPR and other data protection regulations. Data integrity could be compromised, affecting billing accuracy and operational records, potentially causing financial loss and reputational damage. Availability impacts, while rated low, could disrupt service continuity, affecting customer trust and business operations. The remote, unauthenticated nature of the exploit increases the likelihood of attacks, especially in environments with internet-facing management interfaces. Additionally, the lack of patches means organizations must rely on mitigations until an official fix is available, increasing exposure duration. The public disclosure of exploit details further elevates the risk of opportunistic attacks targeting vulnerable systems in Europe.

1. Immediate mitigation should include restricting access to the /add-computer.php endpoint by implementing network-level controls such as IP whitelisting or VPN access to limit exposure to trusted personnel only. 2. Employ Web Application Firewalls (WAFs) with custom rules to detect and block SQL injection patterns targeting the vulnerable parameters 'compname' and 'comploc'. 3. Conduct thorough input validation and sanitization on all user-supplied data, ideally using prepared statements or parameterized queries to prevent SQL injection. 4. If source code access is available, patch the application by refactoring the vulnerable code to use secure database interaction methods. 5. Monitor logs for suspicious activity indicative of SQL injection attempts, such as unusual query patterns or error messages. 6. Educate staff on the risks and signs of exploitation attempts. 7. Plan for an update or migration to a patched or alternative cyber cafe management system once available. 8. Regularly back up databases and configuration files to enable recovery in case of data corruption or loss.
