CVE-2025-70893 identifies a time-based blind SQL Injection vulnerability in the PHPGurukul Cyber Cafe Management System version 1.0, located in the adminprofile.php endpoint. The vulnerability stems from the application's failure to properly sanitize the 'adminname' parameter, which is user-supplied input. An attacker with valid authentication credentials can exploit this flaw by injecting arbitrary SQL expressions into the backend database queries. Time-based blind SQL Injection allows attackers to infer database information by observing response delays, even when direct query results are not returned. This can lead to unauthorized disclosure of sensitive data, modification of database contents, or escalation of privileges within the system. The vulnerability requires authentication, which limits exposure to internal or credentialed threat actors. No CVSS score has been assigned yet, and no patches or known exploits are publicly available. The lack of input validation and use of dynamic SQL queries without parameterization are the root causes. This vulnerability highlights the importance of secure coding practices, especially in web applications managing sensitive operations such as cyber cafe administration.

For European organizations using PHPGurukul Cyber Cafe Management System v1.0, this vulnerability poses a significant risk to the confidentiality and integrity of their data. Successful exploitation could allow attackers to extract sensitive information such as user credentials, configuration data, or financial records stored in the backend database. It could also enable unauthorized modification or deletion of records, disrupting business operations. Given that cyber cafes often serve a wide range of customers, including tourists and local users, a breach could have privacy implications and damage organizational reputation. The requirement for authentication reduces the risk of external attackers but increases the threat from insider attackers or compromised credentials. The absence of known exploits suggests limited current exploitation, but the vulnerability remains a critical risk if left unaddressed. Availability impact is likely low unless attackers use the injection to perform destructive actions. Overall, the threat could lead to regulatory compliance issues under GDPR if personal data is compromised.

To mitigate CVE-2025-70893, organizations should immediately audit and update the PHPGurukul Cyber Cafe Management System to ensure proper input validation and sanitization of all user-supplied data, especially the 'adminname' parameter. Implement parameterized queries or prepared statements to prevent SQL Injection attacks. Restrict access to the adminprofile.php endpoint to only trusted and necessary personnel, employing strong authentication and authorization controls. Monitor logs for unusual database query patterns or delays indicative of time-based SQL Injection attempts. If possible, isolate the database with strict network segmentation to limit lateral movement. Conduct regular security assessments and code reviews focusing on input handling. Since no official patches are currently available, consider applying virtual patching via web application firewalls (WAFs) configured to detect and block SQL Injection payloads targeting this parameter. Educate administrators about the risks of credential compromise and enforce multi-factor authentication to reduce insider threat risks.
