info:
  name: Roxy Fileman 1.4.4 - Arbitrary File Upload
  author: DhiyaneshDK
  severity: high
  description: |
    Roxy Fileman 1.4.4 is susceptible to remote code execution via the FORBIDDEN_UPLOADS setting, which is checked when renaming an existing file to a new file extension. An attacker can bypass this check and rename already uploaded files to any extension using the move function, which does not perform any checks.
