⚠️ Risk & Real-World Impact
Worst Case
Complete compromise of all user accounts leading to unauthorized access to sensitive medical and administrative data, potential data manipulation, and system takeover.
Likely Case
Attackers with database access can decode passwords to gain unauthorized access to user accounts, potentially accessing sensitive healthcare information.
If Mitigated
With proper access controls and monitoring, impact is limited to credential exposure requiring password resets.
🎯 Exploit Status
Exploitation requires access to the encoded passwords from the database and knowledge of the client-side decoding algorithm.
🛠️ Fix & Mitigation

🔍 How to Verify
Check if Vulnerable:
Check application version in administration panel or configuration files. If version is below 4.50.1 (for v4.x) or 5.38.0 (for v5.x), system is vulnerable.Check Version:
Check application configuration or administration interface for version informationVerify Fix Applied:
Confirm version is 4.50.1 or higher (v4.x) or 5.38.0 or higher (v5.x) and verify password storage uses proper hashing instead of reversible encoding.📡 Detection & Monitoring
