CVE-2025-36750
📋 TL;DR
ShineLan-X contains a stored cross-site scripting (XSS) vulnerability in the Plant Name field that allows attackers to inject malicious HTML/JavaScript payloads. When exploited, this can execute arbitrary code in legitimate users' browsers, potentially leading to session hijacking or data theft. This affects all users of ShineLan-X with access to the plant management functionality.

- ShineLan-X
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Attackers could steal administrator credentials, hijack user sessions, redirect users to malicious sites, or perform actions on behalf of authenticated users, potentially leading to complete system compromise.
Likely Case
Attackers with access to plant management functionality could inject malicious scripts that execute when legitimate users view the plant management page, potentially stealing session cookies or performing limited unauthorized actions.
If Mitigated
With proper input validation and output encoding, the vulnerability would be prevented, and even if exploited, the impact would be limited by browser security controls like Content Security Policy (CSP).
🎯 Exploit Status
Exploitation requires the ability to create or modify plant entries. The vulnerability is straightforward to exploit once an attacker gains appropriate access.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Check vendor advisory for specific patched version
Vendor Advisory: https://csirt.divd.nl/CVE-2025-36750/
Restart Required: Yes
Instructions:
1. Check the vendor advisory for the patched version
2. Backup current configuration and data
3. Apply the security patch or upgrade to the fixed version
4. Restart the ShineLan-X service
5. Verify the fix by testing XSS payloads in the Plant Name field
🔧 Temporary Workarounds
Input Validation and Sanitization
allImplement server-side validation to reject or sanitize HTML/JavaScript in the Plant Name field
Implement input validation in the plant management code to strip or encode HTML tags
Content Security Policy
allImplement a strict Content Security Policy to prevent execution of inline scripts
Add CSP header: Content-Security-Policy: script-src 'self'
🧯 If You Can't Patch
- Implement web application firewall (WAF) rules to block XSS payloads in plant management requests
- Restrict access to plant management functionality to trusted users only using network segmentation and access controls
🔍 How to Verify
Check if Vulnerable:
Test by entering a basic XSS payload like <script>alert('XSS')</script> in the Plant Name field and checking if it executes when viewing the plant management pageCheck Version:
Check ShineLan-X administration interface or configuration files for version informationVerify Fix Applied:
After patching, test with the same XSS payloads to ensure they are properly sanitized or rejected and do not execute📡 Detection & Monitoring
