CVE-2018-0024 – Junos OS: A privilege escalation vulnerability exists where authenticated users with shell access can become root
https://notcve.org/view.php?id=CVE-2018-0024
An Improper Privilege Management vulnerability in a shell session of Juniper Networks Junos OS allows an authenticated unprivileged attacker to gain full control of the system. Affected releases are Juniper Networks Junos OS: 12.1X46 versions prior to 12.1X46-D45 on SRX Series; 12.3X48 versions prior to 12.3X48-D20 on SRX Series; 12.3 versions prior to 12.3R11 on EX Series; 14.1X53 versions prior to 14.1X53-D30 on EX2200/VC, EX3200, EX3300/VC, EX4200, EX4300, EX4550/VC, EX4600, EX6200, EX8200/VC (XRE), QFX3500, QFX3600, QFX5100;; 15.1X49 versions prior to 15.1X49-D20 on SRX Series. Una vulnerabilidad de gestión incorrecta de privilegios en una sesión shell de Juniper Networks Junos OS permite que un atacante autenticado sin privilegios obtenga el control total del sistema. Las versiones afectadas son Juniper Networks Junos OS: 12.1X46 en versiones anteriores a la 12.1X46-D45 en SRX Series; 12.3X48 en versiones anteriores a la 12.3X48-D20 en SRX Series; 12.3 en versiones anteriores a la 12.3R11 en EX Series; 14.1X53 en versiones anteriores a la 14.1X53-D30 en EX2200/VC, EX3200, EX3300/VC, EX4200, EX4300, EX4550/VC, EX4600, EX6200, EX8200/VC (XRE), QFX3500, QFX3600, QFX5100 y 15.1X49 en versiones anteriores a la 15.1X49-D20 en SRX Series. • http://www.securityfocus.com/bid/104718 http://www.securitytracker.com/id/1041314 https://kb.juniper.net/JSA10857 • CWE-269: Improper Privilege Management •
CVE-2018-0019 – Junos: Denial of service vulnerability in SNMP MIB-II subagent daemon (mib2d).
https://notcve.org/view.php?id=CVE-2018-0019
A vulnerability in Junos OS SNMP MIB-II subagent daemon (mib2d) may allow a remote network based attacker to cause the mib2d process to crash resulting in a denial of service condition (DoS) for the SNMP subsystem. While a mib2d process crash can disrupt the network monitoring via SNMP, it does not impact routing, switching or firewall functionalities. SNMP is disabled by default on devices running Junos OS. Affected releases are Juniper Networks Junos OS: 12.1X46 versions prior to 12.1X46-D76; 12.3 versions prior to 12.3R12-S7, 12.3R13; 12.3X48 versions prior to 12.3X48-D65; 14.1 versions prior to 14.1R9; 14.1X53 versions prior to 14.1X53-D130; 15.1 versions prior to 15.1F2-S20, 15.1F6-S10, 15.1R7; 15.1X49 versions prior to 15.1X49-D130; 15.1X53 versions prior to 15.1X53-D233, 15.1X53-D471, 15.1X53-D472, 15.1X53-D58, 15.1X53-D66; 16.1 versions prior to 16.1R5-S3, 16.1R7; 16.1X65 versions prior to 16.1X65-D47; 16.1X70 versions prior to 16.1X70-D10; 16.2 versions prior to 16.2R1-S6, 16.2R2-S5, 16.2R3; 17.1 versions prior to 17.1R2-S6, 17.1R3; Una vulnerabilidad en el demonio de subagente SNMP MIB-II (mib2d) de Junos OS podría permitir que un atacante remoto en red provoque que el proceso mib2d se cierre inesperadamente, lo que resulta en una condición de denegación de servicio (DoS) para el subsistema SNMP. Aunque un cierre inesperado del proceso mib2d puede interrumpir la monitorización de red mediante SNMP, no impacta sobre las funcionalidades de enrutamiento, switching o firewall. • http://www.securitytracker.com/id/1040787 https://kb.juniper.net/JSA10847 • CWE-20: Improper Input Validation •
CVE-2018-0020 – Junos OS: rpd daemon cores due to malformed BGP UPDATE packet
https://notcve.org/view.php?id=CVE-2018-0020
Junos OS may be impacted by the receipt of a malformed BGP UPDATE which can lead to a routing process daemon (rpd) crash and restart. Receipt of a repeated malformed BGP UPDATEs can result in an extended denial of service condition for the device. This malformed BGP UPDATE does not propagate to other BGP peers. Affected releases are Juniper Networks Junos OS: 14.1X53 versions prior to 14.1X53-D47; 15.1 versions prior to 15.1F6-S10, 15.1R4-S9, 15.1R6-S6, 15.1R7; 15.1X49 versions prior to 15.1X49-D130 on SRX; 15.1X53 versions prior to 15.1X53-D66 on QFX10K; 15.1X53 versions prior to 15.1X53-D58 on EX2300/EX3400; 15.1X53 versions prior to 15.1X53-D233 on QFX5200/QFX5110; 15.1X53 versions prior to 15.1X53-D471 on NFX; 16.1 versions prior to 16.1R3-S8, 16.1R4-S9, 16.1R5-S3, 16.1R6-S3, 16.1R7; 16.1X65 versions prior to 16.1X65-D47; 16.2 versions prior to 16.2R1-S6, 16.2R2-S5, 16.2R3; 17.1 versions prior to 17.1R2-S3, 17.1R3; 17.2 versions prior to 17.2R1-S3, 17.2R2-S1, 17.2R3; 17.2X75 versions prior to 17.2X75-D70; 13.2 versions above and including 13.2R1.

CVE-2018-0022 – Junos OS: Mbuf leak due to processing MPLS packets in VPLS network.
https://notcve.org/view.php?id=CVE-2018-0022
A Junos device with VPLS routing-instances configured on one or more interfaces may be susceptible to an mbuf leak when processing a specific MPLS packet. Approximately 1 mbuf is leaked per each packet processed. The number of mbufs is platform dependent. The following command provides the number of mbufs that are currently in use and maximum number of mbufs that can be allocated on a platform: > show system buffers 2437/3143/5580 mbufs in use (current/cache/total) Once the device runs out of mbufs it will become inaccessible and a restart will be required. This issue only affects end devices, transit devices are not affected. • http://www.securityfocus.com/bid/103740 http://www.securitytracker.com/id/1040790 https://kb.juniper.net/JSA10855 • CWE-400: Uncontrolled Resource Consumption •
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 •
