CVSS: 8.8EPSS: 0%CPEs: 185EXPL: 0CVE-2021-0208 – Junos OS and Junos OS Evolved: In bidirectional LSP configurations, on MPLS egress router RPD may core upon receipt of specific malformed RSVP packet.
https://notcve.org/view.php?id=CVE-2021-0208
An improper input validation vulnerability in the Routing Protocol Daemon (RPD) service of Juniper Networks Junos OS allows an attacker to send a malformed RSVP packet when bidirectional LSPs are in use, which when received by an egress router crashes the RPD causing a Denial of Service (DoS) condition. Continued receipt of the packet will sustain the Denial of Service. This issue affects: Juniper Networks Junos OS: All versions prior to 17.3R3-S10 except 15.1X49-D240 for SRX series; 17.4 versions prior to 17.4R3-S2; 18.1 versions prior to 18.1R3-S10; 18.2 versions prior to 18.2R2-S7, 18.2R3-S4; 18.3 versions prior to 18.3R3-S2; 18.4 versions prior to 18.4R1-S8, 18.4R2-S6, 18.4R3-S2; 19.1 versions prior to 19.1R1-S5, 19.1R3-S3; 19.2 versions prior to 19.2R3; 19.3 versions prior to 19.3R2-S5, 19.3R3; 19.4 versions prior to 19.4R2-S2, 19.4R3-S1; 20.1 versions prior to 20.1R1-S4, 20.1R2; 15.1X49 versions prior to 15.1X49-D240 on SRX Series. Juniper Networks Junos OS Evolved: 19.3 versions prior to 19.3R2-S5-EVO; 19.4 versions prior to 19.4R2-S2-EVO; 20.1 versions prior to 20.1R1-S4-EVO. Una vulnerabilidad de comprobación de entrada inapropiada en el servicio Routing Protocol Daemon (RPD) de Juniper Networks Junos OS permite a un atacante enviar un paquete RSVP malformado cuando LSP bidireccionales son usados, que cuando lo recibe un enrutador de salida bloquea el RPD causando una condición de Denegación de Servicio (DoS). • https://kb.juniper.net/JSA11098 https://www.juniper.net/documentation/en_US/junos/topics/reference/configuration-statement/corouted-bidirectional-edit-protocols-mpls.html https://www.juniper.net/documentation/en_US/junos/topics/reference/configuration-statement/disable-edit-protocols-rsvp.html • CWE-20: Improper Input Validation •
CVSS: 7.8EPSS: 0%CPEs: 190EXPL: 0CVE-2021-0204 – Junos OS: dexp Local Privilege Escalation vulnerabilities in SUID binaries
https://notcve.org/view.php?id=CVE-2021-0204
A sensitive information disclosure vulnerability in delta-export configuration utility (dexp) of Juniper Networks Junos OS may allow a locally authenticated shell user the ability to create and read database files generated by the dexp utility, including password hashes of local users. Since dexp is shipped with setuid permissions enabled and is owned by the root user, this vulnerability may allow a local privileged user the ability to run dexp with root privileges and access sensitive information in the dexp database. This issue affects Juniper Networks Junos OS: 15.1 versions prior to 15.1R7-S8; 15.1X49 versions prior to 15.1X49-D230; 17.3 versions prior to 17.3R3-S9; 17.4 versions prior to 17.4R2-S12, 17.4R3-S3; 18.1 versions prior to 18.1R3-S11; 18.2 versions prior to 18.2R3-S6; 18.2X75 versions prior to 18.2X75-D34; 18.3 versions prior to 18.3R3-S4; 18.4 versions prior to 18.4R2-S7, 18.4R3-S6; 19.1 versions prior to 19.1R1-S6, 19.1R2-S2, 19.1R3-S3; 19.2 versions prior to 19.2R1-S5, 19.2R3-S1; 19.3 versions prior to 19.3R2-S5, 19.3R3-S1; 19.4 versions prior to 19.4R1-S3, 19.4R2-S2, 19.4R3-S1; 20.1 versions prior to 20.1R1-S4, 20.1R2; 20.2 versions prior to 20.2R1-S2, 20.2R2. Una vulnerabilidad de divulgación de información confidencial en el recurso de configuración de delta-export (dexp) de Juniper Networks Junos OS puede permitir a un usuario del shell autenticado local la capacidad de crear y leer archivos de base de la datos generados por el recurso dexp, incluidos los hash de contraseña de usuarios locales. Dado que dexp es enviado con permisos setuid habilitados y es propiedad del usuario root, esta vulnerabilidad puede permitir a un usuario privilegiado local la capacidad de ejecutar dexp con privilegios root y acceder a información confidencial en la base de datos de dexp. • https://kb.juniper.net/JSA11114 • CWE-250: Execution with Unnecessary Privileges CWE-269: Improper Privilege Management •
CVSS: 8.6EPSS: 0%CPEs: 208EXPL: 0CVE-2021-0203 – Junos OS: EX and QFX5K Series: Storm Control does not work as expected when Redundant Trunk Group is configured
https://notcve.org/view.php?id=CVE-2021-0203
On Juniper Networks EX and QFX5K Series platforms configured with Redundant Trunk Group (RTG), Storm Control profile applied on the RTG interface might not take affect when it reaches the threshold condition. Storm Control enables the device to monitor traffic levels and to drop broadcast, multicast, and unknown unicast packets when a specified traffic level is exceeded, thus preventing packets from proliferating and degrading the LAN. Note: this issue does not affect EX2200, EX3300, EX4200, and EX9200 Series. This issue affects Juniper Networks Junos OS on EX Series and QFX5K Series: 15.1 versions prior to 15.1R7-S7; 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-S2; 18.1 versions prior to 18.1R3-S10; 18.2 versions prior to 18.2R3-S5; 18.3 versions prior to 18.3R2-S4, 18.3R3-S2; 18.4 versions prior to 18.4R2-S5, 18.4R3-S3; 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-S2, 20.1R2. En las plataformas Juniper Networks Serie EX y QFX5K configuradas con Redundant Trunk Group (RTG), el perfil Storm Control aplicado en la interfaz RTG puede no tener efecto cuando alcanza la condición de umbral. • https://kb.juniper.net/JSA11093 • CWE-794: Incomplete Filtering of Multiple Instances of Special Elements •
CVSS: 6.5EPSS: 0%CPEs: 187EXPL: 0CVE-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 •
