CVE-2025-69231
📋 TL;DR
A stored cross-site scripting vulnerability in OpenEMR's GAD-7 anxiety assessment form allows authenticated clinicians to inject malicious JavaScript. When other users view the form, the script executes, potentially enabling session hijacking, account takeover, and privilege escalation to administrator. This affects all OpenEMR installations prior to version 8.0.0.
💻 Affected Systems
- OpenEMR
📦 What is this software?
Openemr by Open Emr
⚠️ Risk & Real-World Impact
Worst Case
An attacker gains administrator privileges, accesses sensitive patient health records, modifies medical data, and potentially compromises the entire healthcare system.
Likely Case
Session hijacking leading to unauthorized access to patient records and potential data exfiltration.
If Mitigated
Limited impact if proper input validation and output encoding are implemented, though some data exposure may still occur.
🎯 Exploit Status
Exploitation requires authenticated clinician access and knowledge of XSS payloads.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 8.0.0
Vendor Advisory: https://github.com/openemr/openemr/security/advisories/GHSA-mf62-q2xc-hxm3
Restart Required: Yes
Instructions:
1. Backup your OpenEMR installation and database. 2. Download OpenEMR version 8.0.0 or later from the official repository. 3. Follow the upgrade instructions in the OpenEMR documentation. 4. Restart the web server and verify the application is functioning correctly.
🔧 Temporary Workarounds
Disable GAD-7 Form Access
allTemporarily restrict access to the vulnerable GAD-7 anxiety assessment form.
# Modify OpenEMR access controls to remove clinician privileges for GAD-7 form
Implement WAF Rules
allConfigure web application firewall to block XSS payloads targeting the GAD-7 form.
# Add WAF rule: SecRule ARGS "<script>" "id:1001,phase:2,deny,msg:'XSS Attempt'"
# Add WAF rule: SecRule REQUEST_URI "/interface/forms/gad7" "id:1002,phase:1,deny,msg:'GAD-7 Form Access Blocked'"
🧯 If You Can't Patch
- Implement strict input validation and output encoding for all user inputs in the GAD-7 form.
- Monitor and audit clinician user activity, especially form submissions and privilege changes.
🔍 How to Verify
Check if Vulnerable:
Check if OpenEMR version is below 8.0.0 and review the GAD-7 form code for lack of input sanitization.Check Version:
grep '\$openemr_version' /path/to/openemr/interface/globals.php | head -1Verify Fix Applied:
Verify OpenEMR version is 8.0.0 or higher and test the GAD-7 form with XSS payloads to ensure they are properly sanitized.📡 Detection & Monitoring
Log Indicators:
- Unusual JavaScript payloads in form submissions
- Multiple failed login attempts from new locations
- Privilege escalation events in audit logs
Network Indicators:
- HTTP requests containing script tags to GAD-7 form endpoints
- Unusual outbound data transfers following form access
