CVE-2022-50941
📋 TL;DR
BootCommerce 3.2.1 contains persistent cross-site scripting (XSS) vulnerabilities in guest order checkout input fields. Attackers can inject malicious scripts that execute when other users view affected pages, potentially compromising user sessions and enabling phishing attacks. This affects all websites running the vulnerable BootCommerce version.
💻 Affected Systems
- BootCommerce
⚠️ Risk & Real-World Impact
Worst Case
Attackers could hijack administrator sessions, steal sensitive customer data, redirect users to phishing sites, or manipulate the e-commerce application to modify orders or steal payment information.
Likely Case
Attackers inject malicious scripts to steal user session cookies, redirect customers to phishing pages, or deface the checkout process with malicious content.
If Mitigated
With proper input validation and output encoding, malicious scripts are neutralized before execution, preventing any client-side code injection.
🎯 Exploit Status
Exploitation requires no authentication and involves simple script injection into checkout form fields. Public vulnerability details available.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: No official vendor advisory found
Restart Required: No
Instructions:
1. Check for updated version from vendor
2. Apply input validation to all guest checkout fields
3. Implement output encoding for user-supplied data
4. Test checkout functionality after fixes
🔧 Temporary Workarounds
Input Validation and Sanitization
allImplement server-side validation and sanitization of all user input in checkout forms
Modify PHP files to add htmlspecialchars() or similar sanitization functions to user inputs
Content Security Policy
allImplement CSP headers to restrict script execution sources
Add Content-Security-Policy header to web server configuration
🧯 If You Can't Patch
- Disable guest checkout functionality entirely
- Implement web application firewall (WAF) rules to block XSS payloads in checkout requests
🔍 How to Verify
Check if Vulnerable:
Test checkout form fields with XSS payloads like <script>alert('XSS')</script> and check if script executes when viewing order detailsCheck Version:
Check BootCommerce version in admin panel or configuration filesVerify Fix Applied:
Test same XSS payloads after fixes to confirm they are properly sanitized and don't execute📡 Detection & Monitoring
Log Indicators:
- Unusual script tags or JavaScript in checkout form submissions
- Multiple failed checkout attempts with script-like content
Network Indicators:
- HTTP requests to checkout endpoints containing script tags or JavaScript code
