1. Remote Code Execution (RCE) – The holy grail for attackers.
2. SQL Injection (SQLi) – Due to improper sanitization in the admin interface.
3. Local File Inclusion (LFI) / Path Traversal – Allowing attackers to read sensitive files.
4. Authentication Bypass – Gaining admin access without credentials.
5. Denial of Service (DoS) – Crashing the mail service.

This "frozen" state makes it an easy target for security researchers and malicious actors who can find unpatched Remote Code Execution (RCE) flaws or memory corruption issues that will likely never receive an official fix. Is Your Server at Risk? Remote Code Execution (RCE) – The holy grail
