Descriptions

An Improper Initialization vulnerability in Juniper Networks Junos OS Evolved may cause a commit operation for disabling the telnet service to not take effect as expected, resulting in the telnet service staying enabled. When it is not intended to be operating on the device, an administrator can issue the following command to verify whether telnet is operating in the background: user@device > show system connections | grep :23 tcp 0 0 0.0.0.0:23 0.0.0.0:* LISTEN 20879/xinetd This issue affects: Juniper Networks Junos OS Evolved All versions prior to 20.4R2-S2-EVO; 21.1 version 21.1R1-EVO and later versions; 21.2 versions prior to 21.2R2-EVO.

Una vulnerabilidad de inicialización inapropiada en Juniper Networks Junos OS Evolved puede causar que una operación de confirmación para deshabilitar el servicio telnet no tenga el efecto esperado, lo que hace que el servicio telnet siga habilitado. Cuando no está previsto que funcione en el dispositivo, un administrador puede emitir el siguiente comando para verificar si telnet está funcionando en segundo plano: user@device ) show system connections | grep :23 tcp 0 0.0.0.0:23 0.0.0.0:* LISTEN 20879/xinetd Este problema afecta: Juniper Networks Junos OS Evolved Todas las versiones anteriores a 20.4R2-S2-EVO; 21.1 versión 21.1R1-EVO y versiones posteriores; versiones 21.2 anteriores a 21.2R2-EVO
