AI Powered Q&A
Can you explain this vulnerability to me?
OpenCTI 3.3.1 has a directory traversal vulnerability in its static/css endpoint. This means an unauthenticated attacker can send specially crafted GET requests containing path traversal sequences like '../' to access arbitrary files on the server's filesystem. For example, an attacker can retrieve sensitive files such as /etc/passwd by exploiting this flaw.
How can this vulnerability impact me? :
This vulnerability allows an attacker to read arbitrary files on the server without authentication, potentially exposing sensitive information such as system configuration files, user data, or credentials. This can lead to information disclosure and further exploitation of the affected system.
