Descriptions

NCR SelfServ ATMs running APTRA XFS 04.02.01 and 05.01.00 implement 512-bit RSA certificates to validate bunch note acceptor (BNA) software updates, which can be broken by an attacker with physical access in a sufficiently short period of time, thereby enabling the attacker to sign arbitrary files and CAB archives used to update BNA software, as well as bypass application whitelisting, resulting in the ability to execute arbitrary code.

Los Cajeros Automáticos NCR SelfServ que ejecutan APTRA XFS versiones 04.02.01 y 05.01.00, implementan certificados RSA de 512 bits para comprobar las actualizaciones del software (BNA), que pueden ser rotas por un atacante con acceso físico en un período de tiempo suficientemente corto, permitiendo que el atacante firme archivos arbitrarios y archivos CAB utilizados para actualizar el software BNA, así como omitir la lista blanca de aplicaciones, resultando en la capacidad de ejecutar código arbitrario.
