CVE-2025-70892 identifies a SQL Injection vulnerability in the Phpgurukul Cyber Cafe Management System version 1.0. The vulnerability exists in the add-users.php endpoint within the user management module, where the username parameter is not properly sanitized or validated before being used in SQL queries. This improper input handling allows an attacker to inject arbitrary SQL commands, potentially manipulating the backend database. Such manipulation can lead to unauthorized data retrieval, modification, or deletion, compromising the confidentiality, integrity, and availability of the system's data. The vulnerability does not require prior authentication, increasing its risk profile. Although no public exploits have been reported yet, the flaw is critical because SQL Injection remains one of the most common and impactful web application vulnerabilities. The lack of a CVSS score means severity must be inferred from the technical details: the vulnerability affects a widely used module (user management), is easy to exploit via direct input manipulation, and can have broad consequences on data security. The absence of patches or mitigation links suggests that affected users must implement their own fixes, such as input validation and parameterized queries. This vulnerability highlights the importance of secure coding practices in web applications managing sensitive user data.

For European organizations using Phpgurukul Cyber Cafe Management System v1.0, this SQL Injection vulnerability could lead to severe consequences including unauthorized access to user data, data corruption, or complete compromise of the backend database. This could result in data breaches exposing personal or financial information of users, undermining trust and potentially violating GDPR regulations. Additionally, attackers could manipulate or delete critical data, disrupting business operations and causing service outages. The vulnerability's exploitation without authentication increases the risk of automated attacks and widespread exploitation. Cyber cafes and related service providers in Europe, which often handle numerous user accounts and payment information, are particularly at risk. The reputational damage and regulatory penalties following a breach could be substantial. Furthermore, attackers could leverage this vulnerability as a foothold for lateral movement within networks, escalating the overall threat landscape for affected organizations.

To mitigate this vulnerability, organizations should immediately implement strict input validation on the username parameter in the add-users.php endpoint, ensuring only expected characters and formats are accepted. Employing prepared statements or parameterized queries is critical to prevent SQL Injection attacks by separating code from data. Database user permissions should be minimized, granting only necessary privileges to the application to limit potential damage. Regular code audits and security testing, including automated scanning for injection flaws, should be conducted. If possible, upgrade to a patched version of the software once available or consider alternative management systems with better security track records. Network-level protections such as Web Application Firewalls (WAFs) can provide temporary mitigation by detecting and blocking malicious payloads targeting this endpoint. Additionally, monitoring logs for unusual database queries or failed login attempts can help detect exploitation attempts early. Finally, ensure compliance with data protection regulations by preparing incident response plans in case of a breach.
