aliases:

details: OpenCTI 3.3.1 is vulnerable to a directory traversal attack via the static/css
  endpoint. An unauthenticated attacker can read arbitrary files from the filesystem
  by sending crafted GET requests with path traversal sequences (e.g., '../') in the
  URL. For example, requesting /static/css//../../../../../../../../etc/passwd returns
  the contents of /etc/passwd. This vulnerability was discovered by Raif Berkay Dincel
  and confirmed on Linux Mint and Windows 10.
