CVE-2013-7389

What is this vulnerability?

CVE-2013-7389 is categorized as a unknown Cross-Site Scripting (XSS) flaw. Based on our vulnerability intelligence, this issue occurs when the application fails to securely handle untrusted data boundaries.

Multiple cross-site scripting (XSS) vulnerabilities in D-Link DIR-645 Router (Rev. A1) with firmware before 1.04B11 allow remote attackers to inject arbitrary web script or HTML via the (1) deviceid parameter to parentalcontrols/bind.php, (2) RESULT parameter to info.php, or (3) receiver parameter to bsc_sms_send.php.

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.

How to Fix and Mitigate CVE-2013-7389

1. Apply Vendor Patches: Upgrade affected components to their latest, non-vulnerable versions immediately.
2. Implement Input Validation: Ensure all user-supplied data is validated, sanitized, and type-checked before processing.
3. Deploy Runtime Protection: Use Precogs continuous monitoring to detect exploitation attempts in real time.
4. Audit Dependencies: Review and update all third-party libraries and transitive dependencies.

Defending with Precogs AI

D-Link DIR-645 routers contain multiple Reflected Cross-Site Scripting (XSS) vulnerabilities in their web interface. Attackers trick an authenticated administrator into clicking a crafted link to hijack the session and modify router configurations. Precogs Application Security Module maps unescaped URL parameters directly to rendering sinks.

Vulnerability Code Signature

Attack Data Flow

Vulnerable Code Pattern

// ❌ VULNERABLE: Direct DOM injection
const userComment = urlParams.get('comment');
// Taint sink: innerHTML executes injected scripts
document.getElementById('comments').innerHTML = userComment;

Secure Code Pattern

// ✅ SECURE: Safe DOM manipulation
const userComment = urlParams.get('comment');
// Sanitized binding: textContent escapes HTML entities
document.getElementById('comments').textContent = userComment;
