CVSS: 6.5EPSS: 0%CPEs: 6EXPL: 0CVE-2021-0209 – Junos OS Evolved: Receipt of certain valid BGP update packets from BGP peers may cause RPD to core when using REGEX.
https://notcve.org/view.php?id=CVE-2021-0209
In Juniper Networks Junos OS Evolved an attacker sending certain valid BGP update packets may cause Junos OS Evolved to access an uninitialized pointer causing RPD to core leading to a Denial of Service (DoS). Continued receipt of these types of valid BGP update packets will cause an extended Denial of Service condition. RPD will require a restart to recover. An indicator of compromise is to see if the file rpd.re exists by issuing the command: show system core-dumps This issue affects: Juniper Networks Junos OS Evolved 19.4 versions prior to 19.4R2-S2-EVO; 20.1 versions prior to 20.1R1-S2-EVO, 20.1R2-S1-EVO.

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.

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: 6.5EPSS: 0%CPEs: 7EXPL: 0CVE-2020-1681 – Junos OS Evolved: Receipt of a specifically malformed NDP packet could lead to Denial of Service
https://notcve.org/view.php?id=CVE-2020-1681
Receipt of a specifically malformed NDP packet sent from the local area network (LAN) to a device running Juniper Networks Junos OS Evolved can cause the ndp process to crash, resulting in a Denial of Service (DoS). The process automatically restarts without intervention, but a continuous receipt of the malformed NDP packets could leaded to an extended Denial of Service condition. During this time, IPv6 neighbor learning will be affected. The issue occurs when parsing the incoming malformed NDP packet. Rather than simply discarding the packet, the process asserts, performing a controlled exit and restart, thereby avoiding any chance of an unhandled exception. • https://kb.juniper.net/JSA11078 • CWE-617: Reachable Assertion CWE-755: Improper Handling of Exceptional Conditions •
CVSS: 6.5EPSS: 0%CPEs: 13EXPL: 0CVE-2020-1678 – Junos OS and Junos OS Evolved: RPD can crash due to a slow memory leak.
https://notcve.org/view.php?id=CVE-2020-1678
On Juniper Networks Junos OS and Junos OS Evolved platforms with EVPN configured, receipt of specific BGP packets causes a slow memory leak. If the memory is exhausted the rpd process might crash. If the issue occurs, the memory leak could be seen by executing the "show task memory detail | match policy | match evpn" command multiple times to check if memory (Alloc Blocks value) is increasing. root@device> show task memory detail | match policy | match evpn ------------------------ Allocator Memory Report ------------------------ Name | Size | Alloc DTXP Size | Alloc Blocks | Alloc Bytes | MaxAlloc Blocks | MaxAlloc Bytes Policy EVPN Params 20 24 3330678 79936272 3330678 79936272 root@device> show task memory detail | match policy | match evpn ------------------------ Allocator Memory Report ------------------------ Name | Size | Alloc DTXP Size | Alloc Blocks | Alloc Bytes | MaxAlloc Blocks | MaxAlloc Bytes Policy EVPN Params 20 24 36620255 878886120 36620255 878886120 This issue affects: Juniper Networks Junos OS 19.4 versions prior to 19.4R2; 20.1 versions prior to 20.1R1-S4, 20.1R2; Juniper Networks Junos OS Evolved: 19.4 versions; 20.1 versions prior to 20.1R1-S4-EVO, 20.1R2-EVO; 20.2 versions prior to 20.2R1-EVO; This issue does not affect: Juniper Networks Junos OS releases prior to 19.4R1.

CVSS: 7.2EPSS: 0%CPEs: 7EXPL: 0CVE-2020-1666 – Junos OS Evolved: 'console log-out-on-disconnect' fails to terminate session on console cable disconnection
https://notcve.org/view.php?id=CVE-2020-1666
The system console configuration option 'log-out-on-disconnect' In Juniper Networks Junos OS Evolved fails to log out an active CLI session when the console cable is disconnected. This could allow a malicious attacker with physical access to the console the ability to resume a previous interactive session and possibly gain administrative privileges. This issue affects all Juniper Networks Junos OS Evolved versions after 18.4R1-EVO, prior to 20.2R1-EVO. La opción de configuración de la consola del sistema "log-out-on-desconect" en Juniper Networks Junos OS Evolved presenta un fallo al cerrar la sesión de una sesión de la CLI activa cuando el cable de la consola está desconectado. Esto podría permitir a un atacante malicioso con acceso físico a la consola la capacidad de reanudar una sesión interactiva anterior y posiblemente conseguir privilegios administrativos. • https://kb.juniper.net/JSA11063 • CWE-284: Improper Access Control CWE-613: Insufficient Session Expiration •
