Technical details
A Cross-Site Request Forgery (CSRF) vulnerability exists in the '/rci' API endpoint of KeeneticOS before version 4.3. The endpoint lacks sufficient CSRF protections and fails to validate the 'Content-Type' header, allowing attackers to bypass standard browser restrictions. An attacker can craft a malicious webpage that, when visited by an authenticated administrator, sends a hidden POST request to the router's API. This request can be used to create a new user with 'cli' and 'http' tags (full administrative rights). The exploit utilizes a 'text/plain' encoding trick to maintain a valid JSON structure in the request body, facilitating the unauthorized configuration change.
