An Improper Input Validation weakness allows a malicious local attacker to elevate their permissions to take control of other portions of the NFX platform they should not be able to access, and execute commands outside their authorized scope of control. This leads to the attacker being able to take control of the entire system. This issue affects: Juniper Networks Junos OS versions prior to 18.2R1 on NFX Series. Una debilidad de Validación de Entrada Inapropiada permite a un atacante local malicioso elevar sus permisos para tomar el control de otras partes de la plataforma NFX a las que no debería poder acceder y ejecutar comandos fuera de su alcance de control autorizado. Esto conlleva al atacante a tomar el control de todo el sistema. • https://kb.juniper.net/JSA10977 • CWE-20: Improper Input Validation •

When configuring a stateless firewall filter in Junos OS, terms named using the format "internal-n" (e.g. "internal-1", "internal-2", etc.) are silently ignored. No warning is issued during configuration, and the config is committed without error, but the filter criteria will match all packets leading to unexpected results. Affected releases are Juniper Networks Junos OS: All versions prior to and including 12.3; 14.1X53 versions prior to 14.1X53-D130, 14.1X53-D49; 15.1 versions prior to 15.1F6-S12, 15.1R7-S4; 15.1X49 versions prior to 15.1X49-D161, 15.1X49-D170; 15.1X53 versions prior to 15.1X53-D236, 15.1X53-D496, 15.1X53-D69; 16.1 versions prior to 16.1R7-S4, 16.1R7-S5; 16.2 versions prior to 16.2R2-S9; 17.1 versions prior to 17.1R3; 17.2 versions prior to 17.2R1-S8, 17.2R3-S1; 17.3 versions prior to 17.3R3-S4; 17.4 versions prior to 17.4R1-S7, 17.4R2-S3; 18.1 versions prior to 18.1R2-S4, 18.1R3-S4; 18.2 versions prior to 18.2R1-S5, 18.2R2-S1; 18.2X75 versions prior to 18.2X75-D40; 18.3 versions prior to 18.3R1-S3; 18.4 versions prior to 18.4R1-S1, 18.4R1-S2. Cuando se configura un filtro de cortafuegos sin estado en Junos OS, los términos nombrados con el formato "internal-n" (por ejemplo, "internal-1", "internal-2", etc.) se ignoran en silencio. • https://kb.juniper.net/JSA10925 • CWE-284: Improper Access Control CWE-754: Improper Check for Unusual or Exceptional Conditions •

Insufficient cross site scripting protection in J-Web component in Juniper Networks Junos OS may potentially allow a remote unauthenticated user to inject web script or HTML and steal sensitive data and credentials from a J-Web session and to perform administrative actions on the Junos device. Juniper SIRT is not aware of any malicious exploitation of this vulnerability. Affected releases are Juniper Networks Junos OS 11.4 prior to 11.4R13-S3; 12.1X44 prior to 12.1X44-D60; 12.1X46 prior to 12.1X46-D40; 12.1X47 prior to 12.1X47-D30; 12.3 prior to 12.3R11; 12.3X48 prior to 12.3X48-D20; 13.2X51 prior to 13.2X51-D39, 13.2X51-D40; 13.3 prior to 13.3R9; 14.1 prior to 14.1R6; 14.2 prior to 14.2R6; 15.1 prior to 15.1R3; 15.1X49 prior to 15.1X49-D20; 15.1X53 prior to 15.1X53-D57. Protección insuficiente contra Cross-Site Scripting (XSS) en el componente J-Web en Juniper Networks Junos OS podría permitir que un usuario remoto no autenticado inyecte scripts web o HTML, robe datos sensibles y credenciales de una sesión J-Web y realice acciones administrativos en el dispositivos Junos. Juniper SIRT no conoce ninguna explotación maliciosa de esta vulnerabilidad. • http://www.securityfocus.com/bid/93529 https://kb.juniper.net/JSA10764 • CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') •
