CVSS: 7.5EPSS: 0%CPEs: 28EXPL: 0CVE-2022-22192 – Junos OS Evolved: PTX Series: An attacker can cause a kernel panic by sending a malformed TCP packet to the device
https://notcve.org/view.php?id=CVE-2022-22192
An Improper Validation of Syntactic Correctness of Input vulnerability in the kernel of Juniper Networks Junos OS Evolved on PTX series allows a network-based, unauthenticated attacker to cause a Denial of Service (DoS). When an incoming TCP packet destined to the device is malformed there is a possibility of a kernel panic. Only TCP packets destined to the ports for BGP, LDP and MSDP can trigger this. This issue only affects PTX10004, PTX10008, PTX10016. No other PTX Series devices or other platforms are affected. • https://kb.juniper.net/JSA69915 • CWE-20: Improper Input Validation CWE-1286: Improper Validation of Syntactic Correctness of Input •
CVSS: 7.8EPSS: 0%CPEs: 200EXPL: 0CVE-2022-22221 – Junos OS: SRX and EX Series: Local privilege escalation flaw in "download" functionality
https://notcve.org/view.php?id=CVE-2022-22221
An Improper Neutralization of Special Elements vulnerability in the download manager of Juniper Networks Junos OS on SRX Series and EX Series allows a locally authenticated attacker with low privileges to take full control over the device. One aspect of this vulnerability is that the attacker needs to be able to execute any of the "request ..." or "show system download ..." commands. This issue affects Juniper Networks Junos OS on SRX Series and EX Series: All versions prior to 19.2R1-S9, 19.2R3-S5; 19.3 versions prior to 19.3R3-S6; 19.4 versions prior to 19.4R3-S8; 20.1 versions prior to 20.1R3-S4; 20.2 versions prior to 20.2R3-S4; 20.3 versions prior to 20.3R3-S3; 20.4 versions prior to 20.4R3-S2, 20.4R3-S3; 21.1 versions prior to 21.1R3-S1; 21.2 versions prior to 21.2R2-S2, 21.2R3; 21.3 versions prior to 21.3R2, 21.3R3; 21.4 versions prior to 21.4R1-S1, 21.4R2. Una vulnerabilidad de Neutralización Inapropiada de Elementos Especiales en el administrador de descargas del Sistema Operativo Junos de Juniper Networks en las series SRX y EX permite a un atacante autenticado localmente con bajos privilegios tomar el control total del dispositivo. Uno de los aspectos de esta vulnerabilidad es que el atacante debe ser capaz de ejecutar cualquiera de los comandos "request ..." o "show system download ...". • https://kb.juniper.net/JSA69725 •
CVSS: 6.5EPSS: 0%CPEs: 260EXPL: 0CVE-2022-22214 – Junos OS and Junos OS Evolved: In an MPLS scenario upon receipt of a specific IPv6 packet an FPC will crash
https://notcve.org/view.php?id=CVE-2022-22214
An Improper Input Validation vulnerability in the Packet Forwarding Engine (PFE) of Juniper Networks Junos OS and Junos OS Evolved allows an adjacent attacker to cause a PFE crash and thereby a Denial of Service (DoS). An FPC will crash and reboot after receiving a specific transit IPv6 packet over MPLS. Continued receipt of this packet will create a sustained Denial of Service (DoS) condition. This issue does not affect systems configured for IPv4 only. This issue affects: Juniper Networks Junos OS All versions prior to 12.3R12-S21; 15.1 versions prior to 15.1R7-S10; 17.3 versions prior to 17.3R3-S12; 18.3 versions prior to 18.3R3-S6; 18.4 versions prior to 18.4R2-S9, 18.4R3-S9; 19.1 versions prior to 19.1R2-S3, 19.1R3-S7; 19.2 versions prior to 19.2R1-S7, 19.2R3-S3; 19.3 versions prior to 19.3R2-S7, 19.3R3-S4; 19.4 versions prior to 19.4R3-S5; 20.1 versions prior to 20.1R3; 20.2 versions prior to 20.2R3-S2; 20.3 versions prior to 20.3R3; 20.4 versions prior to 20.4R2-S2, 20.4R3; 21.1 versions prior to 21.1R2. • https://kb.juniper.net/JSA69718 • CWE-20: Improper Input Validation •
CVSS: 5.9EPSS: 0%CPEs: 41EXPL: 0CVE-2022-22213 – Junos OS and Junos OS Evolved: Denial of Service (DoS) vulnerability in RPD upon receipt of specific BGP update
https://notcve.org/view.php?id=CVE-2022-22213
A vulnerability in Handling of Undefined Values in the routing protocol daemon (RPD) process of Juniper Networks Junos OS and Junos OS Evolved may allow an unauthenticated network-based attacker to crash the RPD process by sending a specific BGP update while the system is under heavy load, leading to a Denial of Service (DoS). Continued receipt and processing of this packet will create a sustained Denial of Service (DoS) condition. Malicious exploitation of this issue requires a very specific combination of load, timing, and configuration of the vulnerable system which is beyond the direct control of the attacker. Internal reproduction has only been possible through artificially created load and specially instrumented source code. Systems are only vulnerable to this issue if BGP multipath is enabled. • https://kb.juniper.net/JSA69717 • CWE-232: Improper Handling of Undefined Values •
CVSS: 7.5EPSS: 0%CPEs: 15EXPL: 1CVE-2022-22209 – Junos OS: RIB and PFEs can get out of sync due to a memory leak caused by interface flaps or route churn
https://notcve.org/view.php?id=CVE-2022-22209
A Missing Release of Memory after Effective Lifetime vulnerability in the kernel of Juniper Networks Junos OS allows an unauthenticated network based attacker to cause a Denial of Service (DoS). On all Junos platforms, the Kernel Routing Table (KRT) queue can get stuck due to a memory leak triggered by interface flaps or route churn leading to RIB and PFEs getting out of sync. The memory leak causes RTNEXTHOP/route and next-hop memory pressure issue and the KRT queue will eventually get stuck with the error- 'ENOMEM -- Cannot allocate memory'. The out-of-sync state between RIB and FIB can be seen with the "show route" and "show route forwarding-table" command. This issue will lead to failures for adding new routes. • https://kb.juniper.net/JSA69713 • CWE-401: Missing Release of Memory after Effective Lifetime •
