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. Juniper Networks Junos OS Evolved releases prior to 19.4R1-EVO.

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 •
CVSS: 7.5EPSS: 0%CPEs: 13EXPL: 0CVE-2020-1648 – Junos OS and Junos OS Evolved: RPD crash when processing a specific BGP packet
https://notcve.org/view.php?id=CVE-2020-1648
On Juniper Networks Junos OS and Junos OS Evolved devices, processing a specific BGP packet can lead to a routing process daemon (RPD) crash and restart. This issue can occur even before the BGP session with the peer is established. Repeated receipt of this specific BGP packet can result in an extended Denial of Service (DoS) condition. This issue affects: Juniper Networks Junos OS: 18.2X75 versions starting from 18.2X75-D50.8, 18.2X75-D60 and later versions, prior to 18.2X75-D52.8, 18.2X75-D53, 18.2X75-D60.2, 18.2X75-D65.1, 18.2X75-D70; 19.4 versions 19.4R1 and 19.4R1-S1; 20.1 versions prior to 20.1R1-S2, 20.1R2. Juniper Networks Junos OS Evolved: 19.4-EVO versions prior to 19.4R2-S2-EVO; 20.1-EVO versions prior to 20.1R2-EVO. • https://kb.juniper.net/JSA11035 • CWE-159: Improper Handling of Invalid Use of Special Elements CWE-690: Unchecked Return Value to NULL Pointer Dereference •
CVSS: 7.5EPSS: 0%CPEs: 4EXPL: 0CVE-2020-1646 – Junos OS and Junos OS Evolved: RPD crash while processing a specific BGP update information.
https://notcve.org/view.php?id=CVE-2020-1646
On Juniper Networks Junos OS and Junos OS Evolved devices, processing a specific UPDATE for an EBGP peer can lead to a routing process daemon (RPD) crash and restart. This issue occurs only when the device is receiving and processing the BGP UPDATE for an EBGP peer. This issue does not occur when the device is receiving and processing the BGP UPDATE for an IBGP peer. However, the offending BGP UPDATE can originally come from an EBGP peer, propagates through the network via IBGP peers without causing crash, then it causes RPD crash when it is processed for a BGP UPDATE towards an EBGP peer. Repeated receipt and processing of the same specific BGP UPDATE can result in an extended Denial of Service (DoS) condition. • https://kb.juniper.net/JSA11033 • CWE-159: Improper Handling of Invalid Use of Special Elements •
