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: 6.8EPSS: 0%CPEs: 44EXPL: 0CVE-2021-0220 – Junos Space: Shared secrets stored in recoverable format and directly exposed through the UI
https://notcve.org/view.php?id=CVE-2021-0220
The Junos Space Network Management Platform has been found to store shared secrets in a recoverable format that can be exposed through the UI. An attacker who is able to execute arbitrary code in the victim browser (for example via XSS) or access cached contents may be able to obtain a copy of credentials managed by Junos Space. The impact of a successful attack includes, but is not limited to, obtaining access to other servers connected to the Junos Space Management Platform. This issue affects Juniper Networks Junos Space versions prior to 20.3R1. Se ha encontrado que Junos Space Network Management Platform almacena secretos compartidos en un formato recuperable que puede ser expuesto por medio de la Interfaz de Usuario. • https://kb.juniper.net/JSA11110 • CWE-257: Storing Passwords in a Recoverable Format CWE-522: Insufficiently Protected Credentials •
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. This issue affects Juniper Networks Junos OS: 14.1X53 versions prior to 14.1X53-D54; 15.1X49 versions prior to 15.1X49-D240 ; 15.1X53 versions prior to 15.1X53-D593; 16.1 versions prior to 16.1R7-S8; 17.2 versions prior to 17.2R3-S4; 17.3 versions prior to 17.3R3-S8; 17.4 versions prior to 17.4R2-S11, 17.4R3-S2; 18.1 versions prior to 18.1R3-S10 ; 18.2 versions prior to 18.2R2-S7, 18.2R3-S3; 18.3 versions prior to 18.3R2-S4, 18.3R3-S2; 18.4 versions prior to 18.4R1-S7, 18.4R2-S4, 18.4R3-S2; 19.1 versions prior to 19.1R1-S5, 19.1R2-S2, 19.1R3; 19.2 versions prior to 19.2R1-S5, 19.2R2; 19.3 versions prior to 19.3R2-S3, 19.3R3; 19.4 versions prior to 19.4R1-S2, 19.4R2. This issue does not affect Juniper Networks Junos OS 12.3, 15.1. En los dispositivos de Juniper Networks Junos serie EX, Serie QFX y serie de la rama SRX, ocurre un filtrado de memoria cada vez que la interfaz del puerto del autenticador 802.1X se interrumpe, lo que puede conllevar a que otros procesos, tales como el proceso pfex, responsable del reenvío de paquetes, se bloquee y reinicie. • https://kb.juniper.net/JSA11105 • CWE-400: Uncontrolled Resource Consumption CWE-401: Missing Release of Memory after Effective Lifetime •
CVSS: 10.0EPSS: 0%CPEs: 336EXPL: 0CVE-2021-0211 – Junos OS and Junos OS Evolved: Upon receipt of a specific BGP FlowSpec message network traffic may be disrupted.
https://notcve.org/view.php?id=CVE-2021-0211
An improper check for unusual or exceptional conditions in Juniper Networks Junos OS and Junos OS Evolved Routing Protocol Daemon (RPD) service allows an attacker to send a valid BGP FlowSpec message thereby causing an unexpected change in the route advertisements within the BGP FlowSpec domain leading to disruptions in network traffic causing a Denial of Service (DoS) condition. Continued receipt of these update messages will cause a sustained Denial of Service condition.
