CVE-2024-47306: Secure Copy Content Protection XSS Flaw

CVE-2024-47306 Overview

CVE-2024-47306 is a stored Cross-Site Scripting (XSS) vulnerability in the Ays Pro Secure Copy Content Protection and Content Locking plugin for WordPress. The flaw affects all plugin versions from n/a through 4.2.3. The issue is tracked under CWE-79 for Improper Neutralization of Input During Web Page Generation.

An unauthenticated attacker can inject malicious JavaScript that executes in the browser of any user who later views the affected page. Exploitation requires user interaction and operates across a security scope change, enabling attackers to target privileged WordPress users.

Critical Impact
Stored JavaScript payloads can hijack administrator sessions, perform actions on behalf of authenticated users, and pivot to broader WordPress site compromise.

Technical Details for CVE-2024-47306

Vulnerability Analysis

The vulnerability is a stored XSS issue in the Secure Copy Content Protection and Content Locking WordPress plugin. The plugin fails to properly neutralize user-supplied input before rendering it back into web pages. Attacker-controlled data is persisted by the plugin and then echoed into HTML output without adequate encoding or sanitization.

When a victim loads the affected page, the stored payload executes in the context of the WordPress origin. Because the scope changes during exploitation, scripts can affect resources beyond the originally vulnerable component, including the WordPress administrative interface.

The attack requires user interaction, typically tricking a privileged user to view content containing the stored payload. Successful exploitation yields limited but meaningful impact on confidentiality, integrity, and availability of the affected site.

Root Cause

The root cause is missing output encoding and insufficient input sanitization in the plugin's content handling routines. Input flowing into plugin-controlled fields is stored in the WordPress database and later rendered without escaping HTML special characters. This violates secure coding guidance for CWE-79.

Attack Vector

The attack vector is network-based and requires no authentication. An attacker submits a crafted payload to a plugin input handler that stores the value server-side. When an administrator or other site visitor views the page containing the stored payload, the script executes in their browser session.

Technical details and the vulnerability disclosure are available in the Patchstack WordPress Vulnerability Advisory.

Detection Methods for CVE-2024-47306

Indicators of Compromise

Unexpected <script> tags, javascript: URIs, or event handler attributes (onerror, onload) stored in plugin-related rows of the WordPress database.
Outbound HTTP requests from administrator browsers to unfamiliar domains shortly after viewing plugin-rendered pages.
New or modified WordPress administrator accounts created without a corresponding audit trail.

Detection Strategies

Audit wp_posts, wp_postmeta, and plugin-specific tables for HTML or JavaScript content in fields that should contain plain text.
Inspect HTTP request logs for POST submissions containing encoded script payloads targeting plugin endpoints.
Compare installed plugin version against 4.2.3 and flag any host running the vulnerable release.

Monitoring Recommendations

Enable a Web Application Firewall (WAF) with rules that block common XSS payload patterns on WordPress admin and plugin endpoints.
Monitor WordPress audit logs for unexpected privilege changes, settings modifications, or content edits.
Alert on browser security events such as Content Security Policy (CSP) violations originating from plugin-rendered pages.

How to Mitigate CVE-2024-47306

Immediate Actions Required

Update the Secure Copy Content Protection and Content Locking plugin to a version newer than 4.2.3 as soon as a fix is available from Ays Pro.
Review stored plugin content for suspicious HTML or JavaScript and purge any malicious entries.
Rotate WordPress administrator credentials and invalidate active sessions if exploitation is suspected.

Patch Information

Refer to the Patchstack WordPress Vulnerability Advisory for vendor patch status. Site operators should subscribe to vendor and Patchstack advisories to receive fixed-version notifications.

Workarounds

Deactivate and remove the plugin if a patched version is not yet available and the functionality is non-essential.
Restrict plugin endpoints with a WAF ruleset blocking <script>, javascript:, and HTML event handler patterns in user input.
Apply a strict Content Security Policy (CSP) that disallows inline scripts to reduce the impact of stored payloads.

bash

# Example restrictive CSP header for an Nginx-fronted WordPress site
add_header Content-Security-Policy "default-src 'self'; script-src 'self'; object-src 'none'; base-uri 'self'; frame-ancestors 'self';" always;
