CVE-2025-1776
📋 TL;DR
A Cross-Site Scripting (XSS) vulnerability in Soteshop versions before 8.3.4 allows remote attackers to inject malicious scripts via the 'query' parameter in the search functionality. This could enable attackers to steal user session cookies, perform actions as authenticated users, or redirect to malicious sites. All Soteshop installations running vulnerable versions are affected.

⚠️ Risk & Real-World Impact
Worst Case
Attackers steal administrator session cookies, gain full administrative access to the e-commerce platform, modify product data, access customer PII, and install backdoors for persistent access.
Likely Case
Attackers steal user session cookies to hijack shopping carts, access personal information, or perform unauthorized purchases using saved payment methods.
If Mitigated
With proper input validation and output encoding, malicious scripts are neutralized before execution, preventing successful exploitation.
🎯 Exploit Status
XSS vulnerabilities are commonly exploited and require minimal technical skill when public PoCs exist.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 8.3.4
Vendor Advisory: https://www.incibe.es/en/incibe-cert/notices/aviso/cross-site-scripting-xss-vulnerability-soteshop
Restart Required: Yes
Instructions:
1. Backup current Soteshop installation and database. 2. Download Soteshop 8.3.4 from official vendor. 3. Follow vendor upgrade instructions. 4. Restart web server. 5. Verify fix by testing search functionality with XSS payloads.
🔧 Temporary Workarounds
Input Validation Filter
allImplement server-side input validation to sanitize the 'query' parameter before processing.
Modify searchResults.php to add: $query = htmlspecialchars($_GET['query'], ENT_QUOTES, 'UTF-8');
WAF Rule
allDeploy Web Application Firewall rules to block XSS payloads in query parameters.
Add WAF rule: SecRule ARGS:query "@rx <script>" "id:1001,phase:2,deny,status:403,msg:'XSS attempt detected'"
🧯 If You Can't Patch
- Implement Content Security Policy (CSP) headers to restrict script execution sources.
- Deploy a reverse proxy with XSS filtering capabilities in front of the vulnerable application.
🔍 How to Verify
Check if Vulnerable:
Test by accessing: https://[your-domain]/app-google-custom-search/searchResults?query=<script>alert('XSS')</script> and check if script executes.Check Version:
Check Soteshop admin panel or view source for version information in footer/headers.Verify Fix Applied:
After patching, repeat the test with the same payload - script should not execute and should be displayed as plain text.📡 Detection & Monitoring
Log Indicators:
- HTTP requests containing <script> tags in query parameters
- Unusual search queries with JavaScript payloads
- Multiple failed search attempts with encoded payloads
Network Indicators:
- HTTP traffic to /app-google-custom-search/searchResults with suspicious query parameters
- Outbound connections to unknown domains following search requests
SIEM Query:
source="web_server" AND uri_path="/app-google-custom-search/searchResults" AND query="*<script>*"
