CVE-2025-5706

Immediate Patch: Check PHPGurukul repository and official channels for a patched version >1.0. If unavailable, contact vendor or review security advisories on phpgurukul.com or GitHub. Code-Level Mitigation: Replace all SQL queries in /new-user-testing.php with parameterized prepared statements using mysqli_prepare() or PDO prepared statements with bound parameters. Example: Use $stmt = $mysqli->prepare('SELECT * FROM users WHERE state = ?'); $stmt->bind_param('s', $_GET['state']); instead of concatenating input directly. Input Validation: Implement strict whitelist validation for the 'state' parameter—define allowed state values and reject any input not matching. For example, if state should only be 'active', 'inactive', 'pending', explicitly check against this list. Web Application Firewall (WAF): Deploy a WAF (ModSecurity, Cloudflare, AWS WAF) with SQL injection detection rules to block common SQLi payloads in the /new-user-testing.php endpoint. Database Hardening: Ensure the database user account running queries has minimal privileges—use a dedicated low-privilege account without DROP, ALTER, or administrative permissions to limit blast radius if injection succeeds. Monitoring: Enable SQL error logging and monitor for unusual query patterns, repeated failed SQL syntax, or UNION-based injection attempts targeting /new-user-testing.php.
