CVE-2024-52875

An issue was discovered in GFI Kerio Control 9.2.5 through 9.4.5. The dest GET parameter passed to the /nonauth/addCertException.cs and /nonauth/guestConfirm.cs and /nonauth/expiration.cs pages is not properly sanitized before being used to generate a Location HTTP header in a 302 HTTP response. This can be exploited to perform Open Redirect or HTTP Response Splitting attacks, which in turn lead to Reflected Cross-Site Scripting (XSS). Remote command execution can be achieved by leveraging the upgrade feature in the admin interface.

Se descubrió un problema en GFI Kerio Control 9.2.5 a 9.4.5. El parámetro GET de destino que se pasa a las páginas /nonauth/addCertException.cs, /nonauth/guestConfirm.cs y /nonauth/expiration.cs no se desinfecta correctamente antes de usarse para generar un encabezado HTTP de ubicación en una respuesta HTTP 302. Esto se puede aprovechar para realizar ataques de redirección abierta o división de respuesta HTTP, que a su vez conducen a Cross-Site Scripting (XSS) Reflejado. La ejecución remota de comandos se puede lograr aprovechando la función de actualización en la interfaz de administración.
