info:
  name: EnGenius EnShare IoT Gigabit Cloud Service 1.4.11 Root Remote Code Execution
  author: intelligent-ears
  severity: critical
  description: |
    An OS command injection vulnerability exists in EnGenius EnShare Cloud Service version 1.4.11 and earlier.The usbinteract.cgi script fails to properly sanitize user input passed to the path parameter, allowing unauthenticated remote attackers to inject arbitrary shell commands.The injected commands are executed with root privileges, leading to full system compromise.
  impact: |
    Unauthenticated attackers can inject and execute arbitrary shell commands with root privileges through the path parameter in usbinteract.cgi, achieving complete system compromise.
  remediation: |
    Upgrade EnGenius EnShare Cloud Service to version 1.4.12 or later that properly sanitizes user input in CGI scripts.
