Descriptions

The ABB IDAL HTTP server CGI interface contains a URL that allows an unauthenticated attacker to bypass authentication and gain access to privileged functions. Specifically, /cgi/loginDefaultUser creates a session in an authenticated state and returns the session ID along with what may be the username and cleartext password of the user. An attacker can then supply an IDALToken value in a cookie, which will allow them to perform privileged operations such as restarting the service with /cgi/restart. A GET request to /cgi/loginDefaultUser may result in "1 #S_OK IDALToken=532c8632b86694f0232a68a0897a145c admin admin" or a similar response.

La interfaz CGI del servidor HTTP ABB IDAL contiene una URL que permite a un atacante no identificado eludir la autenticación y obtener acceso a funciones privilegiadas. Específicamente, / cgi / loginDefaultUser crea una sesión en un estado autenticado y devuelve el ID de sesión junto con lo que puede ser el nombre de usuario y la contraseña de texto simple del usuario. Un atacante puede proporcionar un valor IDALToken en una cookie, lo que les permitirá realizar operaciones privilegiadas, como reiniciar el servicio con / cgi / restart. Una solicitud GET para / cgi / loginDefaultUser puede dar como resultado "1 #S_OK IDALToken = 532c8632b86694f0232a68a0897a145c admin admin" o una respuesta similar.

The IDAL HTTP server CGI interface contains a URL, which allows an unauthenticated attacker to bypass authentication and gain access to privileged functions. In the IDAL CGI interface, there is a URL (/cgi/loginDefaultUser), which will create a session in an authenticated state and return the session ID along with the username and plaintext password of the user. An attacker can then login with the provided credentials or supply the string 'IDALToken=......' in a cookie which will allow them to perform privileged operations such as restarting the service with /cgi/restart.
