  name: Samsung MagicINFO 9 Server 21.1050.0 - Remote Code Execution
  author: iamnoooob,pdresearch
  severity: high
  description: |
    Improper limitation of a pathname to a restricted directory vulnerability in Samsung MagicINFO 9 Server version before 21.1050 allows attackers to write arbitrary file as system authority.
  impact: |
