CVE-2025-4695 is a SQL Injection vulnerability identified in version 1.0 of the PHPGurukul/Campcodes Cyber Cafe Management System, specifically within the /add-users.php file. The vulnerability arises due to improper sanitization or validation of the 'uadd' parameter, which is manipulated to inject malicious SQL code. This flaw allows an unauthenticated remote attacker to execute arbitrary SQL commands on the backend database. The vulnerability does not require user interaction or authentication, increasing its risk profile. The CVSS 4.0 base score is 5.3 (medium severity), reflecting that while the attack vector is network-based and requires low attack complexity, it does require low privileges (PR:L), indicating some level of access is needed, possibly a low-privileged user account. The impact on confidentiality, integrity, and availability is limited (VC:L, VI:L, VA:L), suggesting partial but not full compromise of data or system functions. No known exploits are currently reported in the wild, but the exploit details have been publicly disclosed, increasing the likelihood of exploitation attempts. The absence of patches or mitigation links indicates that no official fix is available yet, making timely defensive measures critical. SQL Injection vulnerabilities can lead to unauthorized data access, data modification, or even full system compromise depending on the database privileges and environment configuration. Given the nature of cyber cafe management systems, which often handle user credentials, session data, and possibly payment information, exploitation could lead to data breaches or service disruption.

For European organizations operating cyber cafes or managing similar public access systems using PHPGurukul Cyber Cafe Management System 1.0, this vulnerability poses a tangible risk. Exploitation could lead to unauthorized access to user data, including personal information of customers, potentially violating GDPR requirements and resulting in regulatory penalties. Data integrity could be compromised, affecting billing or user account management, leading to financial losses or reputational damage. Availability impacts, while rated low, could still disrupt service operations, impacting customer trust and business continuity. Since cyber cafes are often used by a diverse user base, including tourists and local residents, a breach could have wider privacy implications. Additionally, attackers could leverage the compromised system as a foothold for lateral movement within a network if the cyber cafe is part of a larger organizational infrastructure. The public disclosure of the exploit increases the urgency for European organizations to assess and remediate this vulnerability promptly to avoid potential data breaches and compliance violations.

Given the lack of an official patch, European organizations should implement immediate compensating controls. First, conduct a thorough code review and apply input validation and parameterized queries or prepared statements to the /add-users.php file, specifically sanitizing the 'uadd' parameter to prevent SQL injection. Employ Web Application Firewalls (WAFs) with custom rules to detect and block SQL injection patterns targeting this endpoint. Restrict database user privileges to the minimum necessary, ensuring that the database account used by the application cannot perform destructive operations or access unrelated data. Monitor logs for suspicious activities related to the /add-users.php endpoint, focusing on unusual SQL syntax or repeated failed attempts. If feasible, isolate the cyber cafe management system network segment to limit potential lateral movement. Educate staff about the vulnerability and encourage prompt reporting of anomalies. Finally, engage with the vendor or community to track patch releases and apply updates as soon as they become available.
