CVSS: 5.9EPSS: 0%CPEs: 262EXPL: 0CVE-2018-0034 – Junos OS: A malicious crafted IPv6 DHCP packet may cause the JDHCPD daemon to core
https://notcve.org/view.php?id=CVE-2018-0034
A Denial of Service vulnerability exists in the Juniper Networks Junos OS JDHCPD daemon which allows an attacker to core the JDHCPD daemon by sending a crafted IPv6 packet to the system. This issue is limited to systems which receives IPv6 DHCP packets on a system configured for DHCP processing using the JDHCPD daemon. This issue does not affect IPv4 DHCP packet processing. Affected releases are Juniper Networks Junos OS: 12.3 versions prior to 12.3R12-S10 on EX Series; 12.3X48 versions prior to 12.3X48-D70 on SRX Series; 14.1X53 versions prior to 14.1X53-D47 on EX2200/VC, EX3200, EX3300/VC, EX4200, EX4300, EX4550/VC, EX4600, EX6200, EX8200/VC (XRE), QFX3500, QFX3600, QFX5100; 14.1X53 versions prior to 14.1X53-D130 on QFabric; 15.1 versions prior to 15.1R4-S9, 15.1R6-S6, 15.1R7; 15.1X49 versions prior to 15.1X49-D140 on SRX Series; 15.1X53 versions prior to 15.1X53-D67 on QFX10000 Series; 15.1X53 versions prior to 15.1X53-D233 on QFX5110, QFX5200; 15.1X53 versions prior to 15.1X53-D471 on NFX 150, NFX 250; 16.1 versions prior to 16.1R3-S9, 16.1R4-S8, 16.1R5-S4, 16.1R6-S3, 16.1R7; 16.2 versions prior to 16.2R2-S5, 16.2R3; 17.1 versions prior to 17.1R1-S7, 17.1R2-S7, 17.1R3; 17.2 versions prior to 17.2R1-S6, 17.2R2-S4, 17.2R3; 17.3 versions prior to 17.3R1-S4, 17.3R2-S2, 17.3R3; 17.4 versions prior to 17.4R1-S3, 17.4R2. Existe una vulnerabilidad de denegación de servicio (DoS) en el demonio JDHCPD en Junos OS, de Juniper Networks, que permite que un atacante elimine el núcleo del demonio JDHCPD mediante el envío de un paquete IPv6 manipulado al sistema. • http://www.securitytracker.com/id/1041338 https://apps.juniper.net/feature-explorer/search.html#q=dhcp https://kb.juniper.net/JSA10868 • CWE-20: Improper Input Validation •
CVSS: 7.5EPSS: 0%CPEs: 3EXPL: 0CVE-2018-0017 – SRX Series: Denial of service vulnerability in flowd daemon on devices configured with NAT-PT
https://notcve.org/view.php?id=CVE-2018-0017
A vulnerability in the Network Address Translation - Protocol Translation (NAT-PT) feature of Junos OS on SRX series devices may allow a certain valid IPv6 packet to crash the flowd daemon. Repeated crashes of the flowd daemon can result in an extended denial of service condition for the SRX device. Affected releases are Juniper Networks Junos OS: 12.1X46 versions prior to 12.1X46-D72; 12.3X48 versions prior to 12.3X48-D55; 15.1X49 versions prior to 15.1X49-D90. Una vulnerabilidad en la característica Network Address Translation - Protocol Translation (NAT-PT) de Junos OS en dispositivos de serie SRX puede permitir que un determinado paquete IPv6 válido cierre inesperadamente el demonio flowd. El cierre inesperado repetido del demonio flowd puede resultar en una condición de denegación de servicio extendida para los dispositivos de la serie SRX. • http://www.securityfocus.com/bid/103749 http://www.securitytracker.com/id/1040785 https://kb.juniper.net/JSA10845 • CWE-20: Improper Input Validation •
CVSS: 5.9EPSS: 0%CPEs: 215EXPL: 0CVE-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 •
CVSS: 7.5EPSS: 0%CPEs: 85EXPL: 0CVE-2018-0018 – SRX Series: A crafted packet may lead to information disclosure and firewall rule bypass during compilation of IDP policies.
https://notcve.org/view.php?id=CVE-2018-0018
On SRX Series devices during compilation of IDP policies, an attacker sending specially crafted packets may be able to bypass firewall rules, leading to information disclosure which an attacker may use to gain control of the target device or other internal devices, systems or services protected by the SRX Series device. This issue only applies to devices where IDP policies are applied to one or more rules. Customers not using IDP policies are not affected. Depending on if the IDP updates are automatic or not, as well as the interval between available updates, an attacker may have more or less success in performing reconnaissance or bypass attacks on the victim SRX Series device or protected devices. ScreenOS with IDP is not vulnerable to this issue. • http://www.securityfocus.com/bid/103748 http://www.securitytracker.com/id/1040786 https://kb.juniper.net/JSA10846 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •
CVSS: 8.8EPSS: 0%CPEs: 61EXPL: 0CVE-2018-0021 – Junos OS: Short MacSec keys may allow man-in-the-middle attacks.
https://notcve.org/view.php?id=CVE-2018-0021
If all 64 digits of the connectivity association name (CKN) key or all 32 digits of the connectivity association key (CAK) key are not configured, all remaining digits will be auto-configured to 0. Hence, Juniper devices configured with short MacSec keys are at risk to an increased likelihood that an attacker will discover the secret passphrases configured for these keys through dictionary-based and brute-force-based attacks using spoofed packets. Affected releases are Juniper Networks Junos OS: 14.1 versions prior to 14.1R10, 14.1R9; 14.1X53 versions prior to 14.1X53-D47; 15.1 versions prior to 15.1R4-S9, 15.1R6-S6, 15.1R7; 15.1X49 versions prior to 15.1X49-D100; 15.1X53 versions prior to 15.1X53-D59; 16.1 versions prior to 16.1R3-S8, 16.1R4-S8, 16.1R5; 16.2 versions prior to 16.2R1-S6, 16.2R2; 17.1 versions prior to 17.1R2. Si no se configuran todos los 64 dígitos del nombre de la clave de asociación de conectividad (CNK) o todos los 32 dígitos de la clave de asociación de conectividad (CAK), el resto de dígitos se configurarán automáticamente a 0. Por lo tanto, los dispositivos Juniper configurados con claves MacSec cortas están en riesgo de que sea más probable que un atacante descubra las frases de contraseñas secretas configuradas para estas claves a través de ataques basados en diccionario y de fuerza bruta mediante paquetes suplantados. • http://www.securitytracker.com/id/1040789 https://kb.juniper.net/JSA10854 •
