How the CVE Works:
CVE-2025-48253 is a stored Cross-Site Scripting (XSS) vulnerability in the WPFactory “Free Shipping Bar” WooCommerce plugin (versions ≤2.4.6). Attackers inject malicious JavaScript via input fields (e.g., shipping threshold values), which persists in the database. When admins or users view the compromised shipping bar, the script executes in their browser, enabling session hijacking, defacement, or admin takeover. The flaw stems from missing output sanitization and input validation during dynamic HTML generation.
DailyCVE Form:
Platform: WordPress
Version: ≤2.4.6
Vulnerability: Stored XSS
Severity: Critical
Date: 05/29/2025
Prediction: Patch by 06/15/2025
What Undercode Say:
Analytics:
- Exploit Likelihood: High (low skill barrier, no auth required for injection).
- Attack Vector: Web-based (crafted HTTP requests to plugin endpoints).
- Impact Scope: All sites using vulnerable plugin versions.
Exploit Command (PoC):
POST /wp-admin/admin-ajax.php HTTP/1.1 Host: victim.com Content-Type: application/x-www-form-urlencoded Action: wpf_update_settings free_shipping_threshold=<script>alert(document.cookie)</script>
Mitigation Steps:
1. Immediate Workaround:
DELETE FROM wp_options WHERE option_name LIKE '%wpf_free_shipping%';
2. WAF Rule (ModSecurity):
SecRule ARGS "@rx <script>" "id:1005,deny,msg:'XSS Attempt'"
3. Patch Verification:
curl -s https://plugins.trac.wordpress.org/browser/free-shipping-bar/ | grep "Fixed in 2.4.7"
Detection Code (Python):
import requests
target = "http://victim.com/?page_id=2"
response = requests.get(target)
if "<script>alert" in response.text:
print("XSS Detected")
Permanent Fix:
- Update to plugin version ≥2.4.7 (post-patch).
- Implement CSP headers:
add_header Content-Security-Policy "default-src 'self'; script-src 'unsafe-inline'";
Post-Exploit Analysis:
- Check admin logs for suspicious `admin-ajax.php` calls.
- Audit database for injected payloads:
SELECT FROM wp_posts WHERE post_content LIKE '%<script>%';
