CVE-2019-0061

The management daemon (MGD) is responsible for all configuration and management operations in Junos OS. The Junos CLI communicates with MGD over an internal unix-domain socket and is granted special permission to open this protected mode socket. Due to a misconfiguration of the internal socket, a local, authenticated user may be able to exploit this vulnerability to gain administrative privileges. This issue only affects Linux-based platforms. FreeBSD-based platforms are unaffected by this vulnerability. Exploitation of this vulnerability requires Junos shell access. This issue cannot be exploited from the Junos CLI. This issue affects Juniper Networks Junos OS: 15.1X49 versions prior to 15.1X49-D171, 15.1X49-D180; 15.1X53 versions prior to 15.1X53-D496, 15.1X53-D69; 16.1 versions prior to 16.1R7-S4; 16.2 versions prior to 16.2R2-S9; 17.1 versions prior to 17.1R3; 17.2 versions prior to 17.2R1-S8, 17.2R2-S7, 17.2R3-S1; 17.3 versions prior to 17.3R3-S4; 17.4 versions prior to 17.4R1-S6, 17.4R1-S7, 17.4R2-S3, 17.4R3; 18.1 versions prior to 18.1R2-S4, 18.1R3-S4; 18.2 versions prior to 18.2R1-S5, 18.2R2-S2, 18.2R3; 18.3 versions prior to 18.3R1-S3, 18.3R2; 18.4 versions prior to 18.4R1-S2, 18.4R2.

El demonio de administración (MGD) es responsable de todas las operaciones de configuración y gestión en el sistema operativo Junos. La CLI de Junos se comunica con MGD por medio de un socket de dominio unix interno y se le otorga un permiso especial para abrir este socket de modo protegido. Debido a una configuración incorrecta del socket interno, un usuario autenticado local puede explotar esta vulnerabilidad para alcanzar privilegios administrativos. Este problema solo afecta a las plataformas basadas en Linux. Las plataformas basadas en FreeBSD no están afectadas por esta vulnerabilidad. La explotación de esta vulnerabilidad requiere acceso al shell de Junos. Este problema no puede ser explotado desde la CLI de Junos. Este problema afecta al Juniper Networks Junos OS: versiones 15.1X49 anteriores a 15.1X49-D171, 15.1X49-D180; versiones 15.1X53 anteriores a 15.1X53-D496, 15.1X53-D69; versiones 16.1 anteriores a 16.1R7-S4; versiones 16.2 anteriores a 16.2R2-S9; versiones 17.1 anteriores a 17.1R3; versiones 17.2 anteriores a 17.2R1-S8, 17.2R2-S7, 17.2R3-S1; versiones 17.3 anteriores a 17.3R3-S4; versiones 17.4 anteriores a 17.4R1-S6, 17.4R1-S7, 17.4R2-S3, 17.4R3; versiones 18.1 anteriores a 18.1R2-S4, 18.1R3-S4; versiones 18.2 anteriores a 18.2R1-S5, 18.2R2-S2, 18.2R3; versiones 18.3 anteriores a 18.3R1-S3, 18.3R2; versiones 18.4 anteriores a 18.4R1-S2, 18.4R2.
