🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Not available
Vendor Advisory: Not available
Restart Required: No
Instructions:
No official patch available. Consider implementing custom fixes or migrating to alternative software.
🔧 Temporary Workarounds
Implement proper session invalidation
allModify /doctor/change-password.php to properly invalidate all existing sessions when passwords are changed
Edit /doctor/change-password.php to include session_regenerate_id(true) and session_destroy() for old sessions
Add session validation checks
allImplement additional session validation to prevent session fixation attacks
Add session validation logic before processing password change requests
🧯 If You Can't Patch
- Restrict access to /doctor/change-password.php endpoint using network controls or WAF rules
- Implement additional authentication factors for sensitive operations like password changes
🔍 How to Verify
Check if Vulnerable:
Test if changing password invalidates all existing sessions by maintaining multiple active sessionsCheck Version:
Check system version in admin panel or configuration filesVerify Fix Applied:
Verify that after password change, all previous sessions are terminated and require re-authentication📡 Detection & Monitoring
Log Indicators:
- Multiple successful logins from same user in short timeframe
- Password change events followed by unusual account activity
Network Indicators:
- Unusual patterns of requests to /doctor/change-password.php
- Session tokens being reused across different IP addresses
SIEM Query:
source="web_logs" AND (uri="/doctor/change-password.php" AND status=200) AND (user_agent CONTAINS "malicious" OR src_ip IN suspicious_ips)
