https://notcve.org/view.php?id=CVE-2020-1618
On Juniper Networks EX and QFX Series, an authentication bypass vulnerability may allow a user connected to the console port to login as root without any password. This issue might only occur in certain scenarios: • At the first reboot after performing device factory reset using the command “request system zeroize”; or • A temporary moment during the first reboot after the software upgrade when the device configured in Virtual Chassis mode. This issue affects Juniper Networks Junos OS on EX and QFX Series: 14.1X53 versions prior to 14.1X53-D53; 15.1 versions prior to 15.1R7-S4; 15.1X53 versions prior to 15.1X53-D593; 16.1 versions prior to 16.1R7-S4; 17.1 versions prior to 17.1R2-S11, 17.1R3-S1; 17.2 versions prior to 17.2R3-S3; 17.3 versions prior to 17.3R2-S5, 17.3R3-S6; 17.4 versions prior to 17.4R2-S9, 17.4R3; 18.1 versions prior to 18.1R3-S8; 18.2 versions prior to 18.2R2; 18.3 versions prior to 18.3R1-S7, 18.3R2. This issue does not affect Juniper Networks Junos OS 12.3.

CVSS: 8.6EPSS: 0%CPEs: 344EXPL: 0CVE-2020-1613 – Junos OS: BGP session termination upon receipt of specific BGP FlowSpec advertisement.
https://notcve.org/view.php?id=CVE-2020-1613
A vulnerability in the BGP FlowSpec implementation may cause a Juniper Networks Junos OS device to terminate an established BGP session upon receiving a specific BGP FlowSpec advertisement. The BGP NOTIFICATION message that terminates an established BGP session is sent toward the peer device that originally sent the specific BGP FlowSpec advertisement. This specific BGP FlowSpec advertisement received from a BGP peer might get propagated from a Junos OS device running the fixed release to another device that is vulnerable causing BGP session termination downstream. This issue affects IPv4 and IPv6 BGP FlowSpec deployment. This issue affects Juniper Networks Junos OS: 12.3; 12.3X48 on SRX Series; 14.1X53 on EX and QFX Series; 15.1 versions prior to 15.1R7-S5; 15.1F versions prior to 15.1F6-S13; 15.1X49 versions prior to 15.1X49-D180 on SRX Series; 15.1X53 versions prior to 15.1X53-D238 on QFX5200/QFX5110; 15.1X53 versions prior to 15.1X53-D497 on NFX Series; 15.1X53 versions prior to 15.1X53-D592 on EX2300/EX3400; 16.1 versions prior to 16.1R7-S7; 17.1 versions prior to 17.1R2-S12, 17.1R3; 17.2 versions prior to 17.2R2-S7, 17.2R3; 17.2X75 versions prior to 17.2X75-D102, 17.2X75-D110, 17.2X75-D44; 17.3 versions prior to 17.3R2-S5, 17.3R3-S5; 17.4 versions prior to 17.4R1-S8, 17.4R2; 18.1 versions prior to 18.1R2-S4, 18.1R3; 18.2X75 versions prior to 18.2X75-D20. • https://kb.juniper.net/JSA10996 • CWE-710: Improper Adherence to Coding Standards •

https://notcve.org/view.php?id=CVE-2019-0071
Veriexec is a kernel-based file integrity subsystem in Junos OS that ensures only authorized binaries are able to be executed. Due to a flaw in specific versions of Junos OS, affecting specific EX Series platforms, the Veriexec subsystem will fail to initialize, in essence disabling file integrity checking. This may allow a locally authenticated user with shell access to install untrusted executable images, and elevate privileges to gain full control of the system. During the installation of an affected version of Junos OS are installed, the following messages will be logged to the console: Initializing Verified Exec: /sbin/veriexec: Undefined symbol "__aeabi_uidiv" /sbin/veriexec: Undefined symbol "__aeabi_uidiv" /sbin/veriexec: Undefined symbol "__aeabi_uidiv" veriexec: /.mount/packages/db/os-kernel-prd-arm-32-20190221.70c2600_builder_stable_11/boot/brcm-hr3.dtb: Authentication error veriexec: /.mount/packages/db/os-kernel-prd-arm-32-20190221.70c2600_builder_stable_11/boot/contents.izo: Authentication error ...
