CVE-2025-35029
📋 TL;DR
Medical Informatics Engineering Enterprise Health has a stored cross-site scripting (XSS) vulnerability in the 'Demographic Information' page. Authenticated attackers can inject malicious scripts that execute when other users view the page. This affects all users of vulnerable Enterprise Health systems.
💻 Affected Systems
- Medical Informatics Engineering Enterprise Health
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Attackers could steal session cookies, redirect users to malicious sites, perform actions on behalf of victims, or deploy malware through the application.
Likely Case
Attackers with authenticated access could steal sensitive user data, hijack sessions, or deface the application interface.
If Mitigated
With proper input validation and output encoding, the malicious scripts would be rendered harmless as text rather than executable code.
🎯 Exploit Status
Exploitation requires authenticated access to the Enterprise Health system. The attack involves injecting JavaScript into demographic fields that persists and executes when viewed.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Versions updated as of 2025-03-14
Vendor Advisory: https://www.cve.org/CVERecord?id=CVE-2025-35029
Restart Required: No
Instructions:
1. Update Enterprise Health to version patched as of 2025-03-14. 2. Apply vendor-provided patches. 3. Verify the fix by testing XSS payloads in demographic fields.
🔧 Temporary Workarounds
Implement Content Security Policy
allAdd CSP headers to restrict script execution sources
Add 'Content-Security-Policy' header with appropriate directives
Input Validation Filter
allImplement server-side validation to sanitize demographic field inputs
Implement input sanitization for all user-controlled fields in demographic pages
🧯 If You Can't Patch
- Implement web application firewall (WAF) rules to block XSS payloads in POST requests
- Restrict user permissions to minimize who can edit demographic information
🔍 How to Verify
Check if Vulnerable:
Test by entering XSS payloads (e.g., <script>alert('test')</script>) in demographic fields and checking if they execute when viewed.Check Version:
Check Enterprise Health version/update date in system administration interfaceVerify Fix Applied:
Attempt the same XSS payloads after patching; they should be properly encoded and not execute.📡 Detection & Monitoring
Log Indicators:
- Unusual demographic field updates containing script tags or JavaScript code
- Multiple failed login attempts followed by demographic edits
Network Indicators:
- POST requests to demographic endpoints containing script tags or encoded JavaScript
SIEM Query:
source="web_logs" AND (uri="/demographic" OR uri="/patient_info") AND (body CONTAINS "<script>" OR body CONTAINS "javascript:")
