Technical details
A CRLF (Carriage Return Line Feed) injection vulnerability exists in the 'url' parameter of the '/auth' API endpoint in KeeneticOS versions prior to 4.3. The application fails to properly neutralize control characters, allowing an attacker to inject arbitrary HTTP headers and response body content. By crafting a URL that starts with a newline character (%0a), an attacker can bypass the intended redirection, set a 'Content-Type: text/html' header, and deliver a malicious JavaScript payload (XSS). This can be leveraged to perform administrative actions, such as adding new users with full permissions, provided a victim with an active session is induced to click the link. The vulnerability has been patched in KeeneticOS 4.3.
