{"id":"CVE-2020-37041","state":"PUBLISHED","title":"OpenCTI 3.3.1 - Directory Traversal","description":"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.
