CVSS: 7.5EPSS: 0%CPEs: 22EXPL: 1CVE-2021-31353 – Junos OS and Junos OS Evolved: RPD core upon receipt of specific BGP update
https://notcve.org/view.php?id=CVE-2021-31353
19 Oct 2021 — An Improper Handling of Exceptional Conditions vulnerability in Juniper Networks Junos OS and Junos OS Evolved allows an attacker to inject a specific BGP update, causing the routing protocol daemon (RPD) to crash and restart, leading to a Denial of Service (DoS). Continued receipt and processing of the BGP update will create a sustained Denial of Service (DoS) condition. This issue affects very specific versions of Juniper Networks Junos OS: 19.3R3-S2; 19.4R3-S3; 20.2 versions 20.2R2-S3 and later, prior to... • https://kb.juniper.net/JSA11218 • CWE-755: Improper Handling of Exceptional Conditions •

https://notcve.org/view.php?id=CVE-2021-31350
19 Oct 2021 — An Improper Privilege Management vulnerability in the gRPC framework, used by the Juniper Extension Toolkit (JET) API on Juniper Networks Junos OS and Junos OS Evolved, allows a network-based, low-privileged authenticated attacker to perform operations as root, leading to complete compromise of the targeted system. The issue is caused by the JET service daemon (jsd) process authenticating the user, then passing configuration operations directly to the management daemon (mgd) process, which runs as root. Thi... • https://kb.juniper.net/JSA11215 • CWE-269: Improper Privilege Management •
CVSS: 6.5EPSS: 0%CPEs: 5EXPL: 0CVE-2021-0297 – Junos OS Evolved: BGP and LDP sessions with TCP MD5 authentication established with peers not configured for authentication
https://notcve.org/view.php?id=CVE-2021-0297
19 Oct 2021 — A vulnerability in the processing of TCP MD5 authentication in Juniper Networks Junos OS Evolved may allow a BGP or LDP session configured with MD5 authentication to succeed, even if the peer does not have TCP MD5 authentication enabled. This could lead to untrusted or unauthorized sessions being established, resulting in an impact on confidentiality or stability of the network. This issue affects Juniper Networks Junos OS Evolved: All versions prior to 20.3R2-S1-EVO; 20.4 versions prior to 20.4R2-EVO; 21.1... • https://kb.juniper.net/JSA11211 • CWE-755: Improper Handling of Exceptional Conditions •

https://notcve.org/view.php?id=CVE-2021-0286
15 Jul 2021 — A vulnerability in the handling of exceptional conditions in Juniper Networks Junos OS Evolved (EVO) allows an attacker to send specially crafted packets to the device, causing the Advanced Forwarding Toolkit manager (evo-aftmand-bt or evo-aftmand-zx) process to crash and restart, impacting all traffic going through the FPC, resulting in a Denial of Service (DoS). Continued receipt and processing of these packets will create a sustained Denial of Service (DoS) condition.
