CVE-2020-1613

A vulnerability in the BGP FlowSpec implementation may cause a Juniper Networks Junos OS device to terminate an established BGP session upon receiving a specific BGP FlowSpec advertisement. The BGP NOTIFICATION message that terminates an established BGP session is sent toward the peer device that originally sent the specific BGP FlowSpec advertisement. This specific BGP FlowSpec advertisement received from a BGP peer might get propagated from a Junos OS device running the fixed release to another device that is vulnerable causing BGP session termination downstream. This issue affects IPv4 and IPv6 BGP FlowSpec deployment. This issue affects Juniper Networks Junos OS: 12.3; 12.3X48 on SRX Series; 14.1X53 on EX and QFX Series; 15.1 versions prior to 15.1R7-S5; 15.1F versions prior to 15.1F6-S13; 15.1X49 versions prior to 15.1X49-D180 on SRX Series; 15.1X53 versions prior to 15.1X53-D238 on QFX5200/QFX5110; 15.1X53 versions prior to 15.1X53-D497 on NFX Series; 15.1X53 versions prior to 15.1X53-D592 on EX2300/EX3400; 16.1 versions prior to 16.1R7-S7; 17.1 versions prior to 17.1R2-S12, 17.1R3; 17.2 versions prior to 17.2R2-S7, 17.2R3; 17.2X75 versions prior to 17.2X75-D102, 17.2X75-D110, 17.2X75-D44; 17.3 versions prior to 17.3R2-S5, 17.3R3-S5; 17.4 versions prior to 17.4R1-S8, 17.4R2; 18.1 versions prior to 18.1R2-S4, 18.1R3; 18.2X75 versions prior to 18.2X75-D20.

Una vulnerabilidad en la implementación de BGP FlowSpec puede causar que un dispositivo Juniper Networks Junos OS finalice una sesión de BGP establecida al recibir un aviso específico de BGP FlowSpec. El mensaje de BGP NOTIFICATION que finaliza una sesión BGP establecida es enviado al dispositivo peer que originalmente envió el aviso de BGP FlowSpec específico. Este anuncio específico de BGP FlowSpec recibido desde un peer de BGP podría propagarse desde un dispositivo con sistema operativo Junos que ejecuta la versión corregida de otro dispositivo que sea vulnerable, causando la finalización de la sesión de BGP aguas abajo. Este problema afecta a la implementación BGP FlowSpec de IPv4 e IPv6. Este problema afecta a Juniper Networks Junos OS: versión 12.3; versión 12.3X48 en SRX Series; versión 14.1X53 en EX y QFX Series; versiones 15.1 anteriores a 15.1R7-S5 Series; versiones 15.1F anteriores a 15.1F6-S13; versiones 15.1X49 anteriores a 15.1X49-D180 en SRX Series; versiones 15.1X53 anteriores a 15.1X53-D238 en QFX5200/QFX5110; versiones 15.1X53 anteriores a 15.1X53-D497 en NFX Series; versiones 15.1X53 anteriores a 15.1X53-D592 en EX2300/EX3400; versiones 16.1 anteriores a 16.1R7-S7; versiones 17.1 anteriores a 17.1R2-S12, 17.1R3; versiones 17.2 anteriores a 17.2R2-S7, 17.2R3; versiones 17.2X75 anteriores a 17.2X75-D102, 17.2X75-D110, 17.2X75-D44; versiones 17.3 anteriores a 17.3R2-S5, 17.3R3-S5; versiones 17.4 anteriores a 17.4R1-S8, 17.4R2; versiones 18.1 anteriores a 18.1R2-S4, 18.1R3; versiones 18.2X75 anteriores a 18.2X75-D20.
