CVSS: 7.4EPSS: 0%CPEs: 285EXPL: 0CVE-2021-0222 – Junos OS: Upon receipt of certain protocol packets with invalid payloads a self-propagating Denial of Service may occur.
https://notcve.org/view.php?id=CVE-2021-0222
A vulnerability in Juniper Networks Junos OS allows an attacker to cause a Denial of Service (DoS) to the device by sending certain crafted protocol packets from an adjacent device with invalid payloads to the device. These crafted packets, which should be discarded, are instead replicated and sent to the RE. Over time, a Denial of Service (DoS) occurs. Continued receipt of these crafted protocol packets will cause an extended Denial of Service (DoS) condition, which may cause wider traffic impact due to protocol flapping. An indication of compromise is to check "monitor interface traffic" on the ingress and egress port packet counts. • https://kb.juniper.net/JSA11094 • CWE-16: Configuration •
CVSS: 6.5EPSS: 0%CPEs: 221EXPL: 1CVE-2021-0215 – Junos OS: EX Series, QFX Series, SRX Branch Series, MX Series: Memory leak in packet forwarding engine due to 802.1X authenticator port interface flaps
https://notcve.org/view.php?id=CVE-2021-0215
On Juniper Networks Junos EX series, QFX Series, MX Series and SRX branch series devices, a memory leak occurs every time the 802.1X authenticator port interface flaps which can lead to other processes, such as the pfex process, responsible for packet forwarding, to crash and restart. An administrator can use the following CLI command to monitor the status of memory consumption: user@device> show task memory detail Please refer to https://kb.juniper.net/KB31522 for details.

CVSS: 7.5EPSS: 0%CPEs: 151EXPL: 0CVE-2020-1684 – Junos OS: SRX Series: High CPU load due to processing for HTTP traffic when Application Identification is enabled.
https://notcve.org/view.php?id=CVE-2020-1684
On Juniper Networks SRX Series configured with application identification inspection enabled, receipt of specific HTTP traffic can cause high CPU load utilization, which could lead to traffic interruption. Application identification is enabled by default and is automatically turned on when Intrusion Detection and Prevention (IDP), AppFW, AppQoS, or AppTrack is configured. Thus, this issue might occur when IDP, AppFW, AppQoS, or AppTrack is configured. This issue affects Juniper Networks Junos OS on SRX Series: 12.3X48 versions prior to 12.3X48-D105; 15.1X49 versions prior to 15.1X49-D221, 15.1X49-D230; 17.4 versions prior to 17.4R3-S3; 18.1 versions prior to 18.1R3-S11; 18.2 versions prior to 18.2R3-S3; 18.3 versions prior to 18.3R2-S4, 18.3R3-S2; 18.4 versions prior to 18.4R2-S5, 18.4R3-S1; 19.1 versions prior to 19.1R2-S2, 19.1R3; 19.2 versions prior to 19.2R1-S5, 19.2R2; 19.3 versions prior to 19.3R3; 19.4 versions prior to 19.4R2. En Juniper Networks SRX Series configurada con la inspección de identificación de aplicaciones habilitada, la recepción de tráfico HTTP específico puede conllevar una alta utilización de la carga de la CPU, lo que podría conllevar a una interrupción del tráfico. • https://kb.juniper.net/JSA11081 • CWE-400: Uncontrolled Resource Consumption •
