CVE-2020-10181

What is this vulnerability?

CVE-2020-10181 is categorized as a critical Cross-Site Request Forgery (CSRF) flaw with a CVSS base score of 9.8. Based on our vulnerability intelligence, this issue occurs when the application fails to securely handle untrusted data boundaries.

goform/formEMR30 in Sumavision Enhanced Multimedia Router (EMR) 3.0.4.27 allows creation of arbitrary users with elevated privileges (administrator) on a device, as demonstrated by a setString=new_user<1>administrator<1>123456 request.

This architectural defect enables adversaries to bypass intended security controls, directly manipulating the application's execution state or data layer. Immediate strategic intervention is required.

Risk Assessment

Impact on Systems

✅ Data Exfiltration: Attackers can extract sensitive data from backend databases, configuration files, or internal services.

✅ Authentication Bypass: Exploiting this flaw may allow unauthorized access to protected resources and administrative interfaces.

✅ Lateral Movement: Once initial access is gained, attackers can pivot to internal systems and escalate privileges.

Vulnerability Code Signature

Attack Data Flow

Vulnerable Code Pattern

// ❌ VULNERABLE: Missing CSRF token validation
if ($_SERVER['REQUEST_METHOD'] === 'POST') {
    // Taint sink: state change without anti-forgery check
    update_user_email($_POST['email']);
    echo "Email updated successfully.";
}

Secure Code Pattern

// ✅ SECURE: Anti-forgery token validation
session_start();
if ($_SERVER['REQUEST_METHOD'] === 'POST') {
    if (!hash_equals($_SESSION['csrf_token'], $_POST['csrf_token'])) {
        die("CSRF token validation failed.");
    }
    // Sanitized state change
    update_user_email($_POST['email']);
    echo "Email updated successfully.";
}
