CVSS: 5.3EPSS: 0%CPEs: 72EXPL: 0CVE-2022-22204 – Junos OS: MX Series and SRX Series: When receiving a specific SIP packets stale call table entries are created which eventually leads to a DoS for all SIP traffic
https://notcve.org/view.php?id=CVE-2022-22204
An Improper Release of Memory Before Removing Last Reference vulnerability in the Session Initiation Protocol (SIP) Application Layer Gateway (ALG) of Juniper Networks Junos OS allows unauthenticated network-based attacker to cause a partial Denial of Service (DoS). On all MX and SRX platforms, if the SIP ALG is enabled, receipt of a specific SIP packet will create a stale SIP entry. Sustained receipt of such packets will cause the SIP call table to eventually fill up and cause a DoS for all SIP traffic. The SIP call usage can be monitored by "show security alg sip calls". To be affected the SIP ALG needs to be enabled, either implicitly / by default or by way of configuration. • https://kb.juniper.net/JSA69708 • CWE-401: Missing Release of Memory after Effective Lifetime •
CVSS: 6.5EPSS: 0%CPEs: 156EXPL: 1CVE-2022-22202 – Junos OS: PTX Series: FPCs may restart unexpectedly upon receipt of specific MPLS packets with certain multi-unit interface configurations
https://notcve.org/view.php?id=CVE-2022-22202
An Improper Handling of Exceptional Conditions vulnerability on specific PTX Series devices, including the PTX1000, PTX3000 (NextGen), PTX5000, PTX10002-60C, PTX10008, and PTX10016 Series, in Juniper Networks Junos OS allows an unauthenticated MPLS-based attacker to cause a Denial of Service (DoS) by triggering the dcpfe process to crash and FPC to restart. On affected PTX Series devices, processing specific MPLS packets received on an interface with multiple units configured may cause FPC to restart unexpectedly. Continued receipt and processing of this packet will create a sustained Denial of Service (DoS) condition. This issue only affects PTX Series devices utilizing specific FPCs found on PTX1000, PTX3000 (NextGen), PTX5000, PTX10002-60C, PTX10008, and PTX10016 Series devices, only if multiple units are configured on the ingress interface, and at least one unit has 'family mpls' *not* configured. See the configuration sample below for more information. • https://kb.juniper.net/JSA69706 • CWE-755: Improper Handling of Exceptional Conditions •
CVSS: 7.5EPSS: 0%CPEs: 55EXPL: 0CVE-2022-22198 – Junos OS: MX MS-MPC or MS-MIC, or SRX SPC crashes if it receives a SIP message with a specific contact header format
https://notcve.org/view.php?id=CVE-2022-22198
An Access of Uninitialized Pointer vulnerability in the SIP ALG of Juniper Networks Junos OS allows an unauthenticated network-based attacker to cause a Denial of Service (DoS). Continued receipt of these specific packets will cause a sustained Denial of Service condition. On all MX and SRX platforms, if the SIP ALG is enabled, an MS-MPC or MS-MIC, or SPC will crash if it receives a SIP message with a specific contact header format. This issue affects Juniper Networks Junos OS on MX Series and SRX Series: 20.4 versions prior to 20.4R3; 21.1 versions prior to 21.1R2-S1, 21.1R3; 21.2 versions prior to 21.2R2. This issue does not affect versions prior to 20.4R1. • https://kb.juniper.net/JSA69513 • CWE-824: Access of Uninitialized Pointer •
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 •
CVSS: 5.5EPSS: 0%CPEs: 30EXPL: 0CVE-2022-22193 – Junos OS and Junos OS Evolved: In a BGP rib-sharding scenario when a certain CLI command is executed the rpd process might crash
https://notcve.org/view.php?id=CVE-2022-22193
An Improper Handling of Unexpected Data Type vulnerability in the Routing Protocol Daemon (rpd) of Juniper Networks Junos OS and Junos OS Evolved allows a locally authenticated attacker with low privileges to cause a Denial of Service (DoS). Continued execution of this command might cause a sustained Denial of Service condition. If BGP rib sharding is configured and a certain CLI command is executed the rpd process can crash. During the rpd crash and restart, the routing protocols might be impacted and traffic disruption might be seen due to the loss of routing information. This issue affects: Juniper Networks Junos OS 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. • https://kb.juniper.net/JSA69503 • CWE-241: Improper Handling of Unexpected Data Type •
