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: 6.5EPSS: 0%CPEs: 142EXPL: 1CVE-2022-22215 – Junos OS and Junos OS Evolved: /var/run/<pid>.env files are potentially not deleted during termination of a gRPC connection causing inode exhaustion
https://notcve.org/view.php?id=CVE-2022-22215
A Missing Release of File Descriptor or Handle after Effective Lifetime vulnerability in plugable authentication module (PAM) of Juniper Networks Junos OS and Junos OS Evolved allows a locally authenticated attacker with low privileges to cause a Denial of Service (DoS). It is possible that after the termination of a gRPC connection the respective/var/run/<pid>.env file is not getting deleted which if occurring repeatedly can cause inode exhaustion. Inode exhaustion can present itself in two different ways: 1. The following log message can be observed: host kernel: pid <pid> (<process>), uid <uid> inumber <number> on /.mount/var: out of inodes which by itself is a clear indication. 2. The following log message can be observed: host <process>[<pid>]: ... : No space left on device which is not deterministic and just a representation of a write error which could have several reasons. • https://kb.juniper.net/JSA69719 • CWE-772: Missing Release of Resource after Effective Lifetime •
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: 6.5EPSS: 0%CPEs: 82EXPL: 0CVE-2022-22196 – Junos OS and Junos OS Evolved: The rpd CPU spikes to 100% after a malformed ISIS TLV has been received
https://notcve.org/view.php?id=CVE-2022-22196
An Improper Check for Unusual or Exceptional Conditions vulnerability in the Routing Protocol Daemon (rpd) of Juniper Networks Junos OS and Junos OS Evolved allows an adjacent, unauthenticated attacker with an established ISIS adjacency to cause a Denial of Service (DoS). The rpd CPU spikes to 100% after a malformed ISIS TLV has been received which will lead to processing issues of routing updates and in turn traffic impact. This issue affects: Juniper Networks Junos OS 19.3 versions prior to 19.3R3-S4; 19.4 versions prior to 19.4R2-S6, 19.4R3-S6; 20.1 versions prior to 20.1R3-S2; 20.2 versions prior to 20.2R3-S3; 20.3 versions prior to 20.3R3-S1; 20.4 versions prior to 20.4R3; 21.1 versions prior to 21.1R3; 21.2 versions prior to 21.2R2. Juniper Networks Junos OS Evolved All versions prior to 20.4R3-S3-EVO; 21.2 versions prior to 21.2R2-EVO. This issue does not affect Juniper Networks Junos OS versions prior to 19.3R1. • https://kb.juniper.net/JSA69509 • CWE-754: Improper Check for Unusual or Exceptional Conditions •
