CVE-2020-1688 – Junos OS: SRX and NFX Series: Insufficient Web API private key protection

https://notcve.org/view.php?id=CVE-2020-1688

On Juniper Networks SRX Series and NFX Series, a local authenticated user with access to the shell may obtain the Web API service private key that is used to provide encrypted communication between the Juniper device and the authenticator services. Exploitation of this vulnerability may allow an attacker to decrypt the communications between the Juniper device and the authenticator service. This Web API service is used for authentication services such as the Juniper Identity Management Service, used to obtain user identity for Integrated User Firewall feature, or the integrated ClearPass authentication and enforcement feature. This issue affects Juniper Networks Junos OS on Networks SRX Series and NFX Series: 12.3X48 versions prior to 12.3X48-D105; 15.1X49 versions prior to 15.1X49-D190; 16.1 versions prior to 16.1R7-S8; 17.2 versions prior to 17.2R3-S4; 17.3 versions prior to 17.3R3-S8; 17.4 versions prior to 17.4R2-S11, 17.4R3; 18.1 versions prior to 18.1R3-S7; 18.2 versions prior to 18.2R3; 18.3 versions prior to 18.3R2-S4, 18.3R3; 18.4 versions prior to 18.4R1-S7, 18.4R2; 19.1 versions prior to 19.1R2; 19.2 versions prior to 19.2R1-S4, 19.2R2. En Juniper Networks SRX Series y NFX Series, un usuario autenticado local con acceso al shell puede obtener la clave privada del servicio Web API que es usada para proporcionar comunicación cifrada entre el dispositivo Juniper y los servicios de autenticación. • https://kb.juniper.net/InfoCenter/index?page=content&id=KB30911 https://kb.juniper.net/JSA11085 https://www.juniper.net/documentation/en_US/junos/topics/reference/configuration-statement/services-webapi-user-cli.html https://www.juniper.net/documentation/en_US/junos/topics/topic-map/security-user-auth-configure-jims.html https://www.juniper.net/documentation/en_US/junos/topics/topic-map/security-user-auth-intergrated-user-firewall-overview.html • CWE-320: Key Management Errors CWE-359: Exposure of Private Personal Information to an Unauthorized Actor CWE-522: Insufficiently Protected Credentials •

CVE-2020-1687 – Junos OS: EX4300-MP/EX4600/QFX5K Series: High CPU load due to receipt of specific layer 2 frames in EVPN-VXLAN deployment.

https://notcve.org/view.php?id=CVE-2020-1687

On Juniper Networks EX4300-MP Series, EX4600 Series and QFX5K Series deployed in (Ethernet VPN) EVPN-(Virtual Extensible LAN) VXLAN configuration, receipt of a stream of specific VXLAN encapsulated layer 2 frames can cause high CPU load, which could lead to network protocol operation issue and traffic interruption. This issue affects devices that are configured as a Layer 2 or Layer 3 gateway of an EVPN-VXLAN deployment. The offending layer 2 frames that cause the issue originate from a different access switch that get encapsulated within the same EVPN-VXLAN domain. This issue affects Juniper Networks Junos OS on EX4300-MP Series, EX4600 Series and QFX5K Series: 17.3 versions prior to 17.3R3-S9; 17.4 versions prior to 17.4R2-S11, 17.4R3-S2, 17.4R3-S3; 18.1 versions prior to 18.1R3-S11; 18.2 versions prior to 18.2R3-S5; 18.3 versions prior to 18.3R2-S4, 18.3R3-S3; 18.4 versions prior to 18.4R2-S5, 18.4R3-S4; 19.1 versions prior to 19.1R2-S2, 19.1R3-S2; 19.2 versions prior to 19.2R1-S5, 19.2R2-S1, 19.2R3; 19.3 versions prior to 19.3R2-S4, 19.3R3; 19.4 versions prior to 19.4R1-S3, 19.4R2-S1, 19.4R3; 20.1 versions prior to 20.1R1-S3, 20.1R2. En Juniper Networks EX4300-MP Series, EX4600 Series y QFX5K Series implementadas en (Ethernet VPN) EVPN-(Virtual Extensible LAN) VXLAN, la recepción de un flujo de tramas de capa 2 encapsuladas de VXLAN específicas puede causar una alta carga de CPU, lo que podría conllevar a problema de funcionamiento del protocolo de red e interrupción del tráfico. • https://kb.juniper.net/JSA11084 • CWE-400: Uncontrolled Resource Consumption •

CVE-2020-1684 – Junos OS: SRX Series: High CPU load due to processing for HTTP traffic when Application Identification is enabled.

https://notcve.org/view.php?id=CVE-2020-1684

On Juniper Networks SRX Series configured with application identification inspection enabled, receipt of specific HTTP traffic can cause high CPU load utilization, which could lead to traffic interruption. Application identification is enabled by default and is automatically turned on when Intrusion Detection and Prevention (IDP), AppFW, AppQoS, or AppTrack is configured. Thus, this issue might occur when IDP, AppFW, AppQoS, or AppTrack is configured. This issue affects Juniper Networks Junos OS on SRX Series: 12.3X48 versions prior to 12.3X48-D105; 15.1X49 versions prior to 15.1X49-D221, 15.1X49-D230; 17.4 versions prior to 17.4R3-S3; 18.1 versions prior to 18.1R3-S11; 18.2 versions prior to 18.2R3-S3; 18.3 versions prior to 18.3R2-S4, 18.3R3-S2; 18.4 versions prior to 18.4R2-S5, 18.4R3-S1; 19.1 versions prior to 19.1R2-S2, 19.1R3; 19.2 versions prior to 19.2R1-S5, 19.2R2; 19.3 versions prior to 19.3R3; 19.4 versions prior to 19.4R2. En Juniper Networks SRX Series configurada con la inspección de identificación de aplicaciones habilitada, la recepción de tráfico HTTP específico puede conllevar una alta utilización de la carga de la CPU, lo que podría conllevar a una interrupción del tráfico. • https://kb.juniper.net/JSA11081 • CWE-400: Uncontrolled Resource Consumption •

CVE-2020-1680 – Junos OS: MX Series: MS-MPC/MIC might crash when processing malformed IPv6 packet in NAT64 configuration.

https://notcve.org/view.php?id=CVE-2020-1680

On Juniper Networks MX Series with MS-MIC or MS-MPC card configured with NAT64 configuration, receipt of a malformed IPv6 packet may crash the MS-PIC component on MS-MIC or MS-MPC. This issue occurs when a multiservice card is translating the malformed IPv6 packet to IPv4 packet. An unauthenticated attacker can continuously send crafted IPv6 packets through the device causing repetitive MS-PIC process crashes, resulting in an extended Denial of Service condition. This issue affects Juniper Networks Junos OS on MX Series: 15.1 versions prior to 15.1R7-S7; 15.1X53 versions prior to 15.1X53-D593; 16.1 versions prior to 16.1R7-S8; 17.2 versions prior to 17.2R3-S4; 17.3 versions prior to 17.3R3-S6; 17.4 versions prior to 17.4R2-S11, 17.4R3; 18.1 versions prior to 18.1R3-S11; 18.2 versions prior to 18.2R3-S6; 18.2X75 versions prior to 18.2X75-D41, 18.2X75-D430, 18.2X75-D53, 18.2X75-D65; 18.3 versions prior to 18.3R2-S4, 18.3R3; 18.4 versions prior to 18.4R2-S5, 18.4R3; 19.1 versions prior to 19.1R2; 19.2 versions prior to 19.2R1-S5, 19.2R2; 19.3 versions prior to 19.3R2. En Juniper Networks MX Series con tarjeta MS-MIC o MS-MPC configurada con configuración NAT64, la recepción de un paquete IPv6 malformado puede bloquear el componente MS-PIC en MS-MIC o MS-MPC. • https://kb.juniper.net/JSA11077 • CWE-131: Incorrect Calculation of Buffer Size •
