CVE-2018-0005 – Security Bulletin: Junos OS: MAC move limit configured to drop traffic may forward traffic.
https://notcve.org/view.php?id=CVE-2018-0005
QFX and EX Series switches configured to drop traffic when the MAC move limit is exceeded will forward traffic instead of dropping traffic. This can lead to denials of services or other unintended conditions. Affected releases are Juniper Networks Junos OS: 14.1X53 versions prior to 14.1X53-D40; 15.1X53 versions prior to 15.1X53-D55; 15.1 versions prior to 15.1R7. Los switches de las series QFX y EX configurados para volcar el tráfico cuando se excede el límite de movimiento de MAC redireccionan tráfico en vez de volcarlo. Esto puede provocar denegaciones de servicio (DoS) u otras condiciones no esperadas. • http://www.securitytracker.com/id/1040182 https://kb.juniper.net/JSA10833 • CWE-754: Improper Check for Unusual or Exceptional Conditions •
CVE-2018-0008 – Junos OS: commit script may allow unauthenticated root login upon reboot
https://notcve.org/view.php?id=CVE-2018-0008
An unauthenticated root login may allow upon reboot when a commit script is used. A commit script allows a device administrator to execute certain instructions during commit, which is configured under the [system scripts commit] stanza. Certain commit scripts that work without a problem during normal commit may cause unexpected behavior upon reboot which can leave the system in a state where root CLI login is allowed without a password due to the system reverting to a "safe mode" authentication state. Lastly, only logging in physically to the console port as root, with no password, will work. Affected releases are Juniper Networks Junos OS: 12.1X46 versions prior to 12.1X46-D71 on SRX; 12.3X48 versions prior to 12.3X48-D55 on SRX; 14.1 versions prior to 14.1R9; 14.1X53 versions prior to 14.1X53-D40 on QFX, EX; 14.2 versions prior to 14.2R7-S9, 14.2R8; 15.1 versions prior to 15.1F5-S7, 15.1F6-S8, 15.1R5-S6, 15.1R6; 15.1X49 versions prior to 15.1X49-D110 on SRX; 15.1X53 versions prior to 15.1X53-D232 on QFX5200/5110; 15.1X53 versions prior to 15.1X53-D49, 15.1X53-D470 on NFX; 15.1X53 versions prior to 15.1X53-D65 on QFX10K; 16.1 versions prior to 16.1R2. • http://www.securitytracker.com/id/1040186 https://kb.juniper.net/JSA10835 https://lists.apache.org/thread.html/rfb87e0bf3995e7d560afeed750fac9329ff5f1ad49da365129b7f89e%40%3Ccommits.cxf.apache.org%3E • CWE-287: Improper Authentication •
CVE-2017-2341 – Junos OS: VM to host privilege escalation in platforms with Junos OS running in a virtualized environment.
https://notcve.org/view.php?id=CVE-2017-2341
An insufficient authentication vulnerability on platforms where Junos OS instances are run in a virtualized environment, may allow unprivileged users on the Junos OS instance to gain access to the host operating environment, and thus escalate privileges. Affected releases are Juniper Networks Junos OS 14.1X53 prior to 14.1X53-D40 on QFX5110, QFX5200, QFX10002, QFX10008, QFX10016, EX4600 and NFX250; 15.1 prior to 15.1R5 on EX4600; 15.1X49 prior to 15.1X49-D70 on vSRX, SRX1500, SRX4100, SRX4200; 16.1 prior to 16.1R2 on EX4600, ACX5000 series. This issue does not affect vMX. No other Juniper Networks products or platforms are affected by this issue. Una vulnerabilidad de autenticación insuficiente en plataformas donde las instancias de Junos OS se ejecutan en un entorno virtualizado, puede permitir que los usuarios sin privilegios de la instancia de Junos OS alcanzar acceso al entorno operativo del host y, por lo tanto, escalar los privilegios. • http://www.securitytracker.com/id/1038893 https://kb.juniper.net/JSA10787 • CWE-287: Improper Authentication •
