CVSS: 6.5EPSS: 0%CPEs: 147EXPL: 0CVE-2022-22238 – Junos OS and Junos OS Evolved: The rpd process will crash when a malformed incoming RESV message is processed
https://notcve.org/view.php?id=CVE-2022-22238
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 unauthenticated, adjacent attacker to cause a Denial of Service (DoS). When an incoming RESV message corresponding to a protected LSP is malformed it causes an incorrect internal state resulting in an rpd core. This issue affects: Juniper Networks Junos OS All versions prior to 19.2R3-S6; 19.3 versions prior to 19.3R3-S6; 19.4 versions prior to 19.4R3-S8; 20.1 versions prior to 20.1R3-S2; 20.2 versions prior to 20.2R3-S3; 20.3 versions prior to 20.3R3-S2; 20.4 versions prior to 20.4R3-S1; 21.1 versions prior to 21.1R3; 21.2 versions prior to 21.2R1-S2, 21.2R3; 21.3 versions prior to 21.3R2.

Una vulnerabilidad de Comprobación Inapropiada de Condiciones Inusuales o Excepcionales en el demonio de protocolo de enrutamiento (rpd) de Juniper Networks Junos OS y Junos OS Evolved permite a un atacante adyacente no autenticado causar una Denegación de Servicio (DoS). • https://kb.juniper.net/JSA69894 • CWE-754: Improper Check for Unusual or Exceptional Conditions •
CVSS: 6.5EPSS: 0%CPEs: 181EXPL: 0CVE-2022-22230 – Junos OS and Junos OS Evolved: RPD crash upon receipt of specific OSPFv3 LSAs
https://notcve.org/view.php?id=CVE-2022-22230
An Improper Input Validation vulnerability in the Routing Protocol Daemon (rpd) of Juniper Networks Junos OS and Junos OS Evolved allows an adjacent unauthenticated attacker to cause DoS (Denial of Service). If another router generates more than one specific valid OSPFv3 LSA then rpd will crash while processing these LSAs. This issue only affects systems configured with OSPFv3, while OSPFv2 is not affected. This issue affects: Juniper Networks Junos OS 19.2 versions prior to 19.2R3-S6; 19.3 version 19.3R2 and later versions; 19.4 versions prior to 19.4R2-S8, 19.4R3-S9; 20.1 version 20.1R1 and later versions; 20.2 versions prior to 20.2R3-S5; 20.3 versions prior to 20.3R3-S5; 20.4 versions prior to 20.4R3-S4; 21.1 versions prior to 21.1R3-S2; 21.2 versions prior to 21.2R3-S1; 21.3 versions prior to 21.3R3-S2; 21.4 versions prior to 21.4R2.

CVSS: 5.3EPSS: 0%CPEs: 26EXPL: 0CVE-2022-22227 – Junos OS Evolved: ACX7000 Series: Specific IPv6 transit traffic gets exceptioned to the routing-engine which causes increased CPU utilization
https://notcve.org/view.php?id=CVE-2022-22227
An Improper Check for Unusual or Exceptional Conditions vulnerability in the Packet Forwarding Engine (PFE) of Juniper Networks Junos OS Evolved on ACX7000 Series allows an unauthenticated network-based attacker to cause a partial Denial of Service (DoS). On receipt of specific IPv6 transit traffic, Junos OS Evolved on ACX7100-48L, ACX7100-32C and ACX7509 sends this traffic to the Routing Engine (RE) instead of forwarding it, leading to increased CPU utilization of the RE and a partial DoS. This issue only affects systems configured with IPv6. This issue does not affect ACX7024 which is supported from 22.3R1-EVO onwards where the fix has already been incorporated as indicated in the solution section. This issue affects Juniper Networks Junos OS Evolved on ACX7100-48L, ACX7100-32C, ACX7509: 21.1-EVO versions prior to 21.1R3-S2-EVO; 21.2-EVO versions prior to 21.2R3-S2-EVO; 21.3-EVO versions prior to 21.3R3-EVO; 21.4-EVO versions prior to 21.4R1-S1-EVO, 21.4R2-EVO. • https://kb.juniper.net/JSA69878 • CWE-754: Improper Check for Unusual or Exceptional Conditions •
CVSS: 5.9EPSS: 0%CPEs: 92EXPL: 0CVE-2022-22225 – Junos OS and Junos OS Evolved: In a BGP multipath scenario, when one of the contributing routes is flapping often and rapidly, rpd may crash
https://notcve.org/view.php?id=CVE-2022-22225
A Time-of-check Time-of-use (TOCTOU) Race Condition vulnerability in the Routing Protocol Daemon (rpd) of Juniper Networks Junos OS and Junos OS Evolved allows an unauthenticated attacker with an established BGP session to cause a Denial of Service (DoS). In a BGP multipath scenario, when one of the contributing routes is flapping often and rapidly, rpd may crash. As this crash depends on whether a route is a contributing route, and on the internal timing of the events triggered by the flap this vulnerability is outside the direct control of a potential attacker. This issue affects: Juniper Networks Junos OS 19.2 versions prior to 19.2R3-S6; 20.2 versions prior to 20.2R3-S4; 20.3 versions prior to 20.3R3-S3; 20.4 versions prior to 20.4R3-S4; 21.1 versions prior to 21.1R3; 21.2 versions prior to 21.2R2; 21.3 versions prior to 21.3R2. Juniper Networks Junos OS Evolved All versions prior to 20.4R3-S4-EVO; 21.1-EVO version 21.1R1-EVO and later versions; 21.2-EVO versions prior to 21.2R2-EVO; 21.3-EVO versions prior to 21.3R2-EVO. • https://kb.juniper.net/JSA69875 • CWE-367: Time-of-check Time-of-use (TOCTOU) Race Condition •
CVSS: 6.5EPSS: 0%CPEs: 125EXPL: 0CVE-2022-22224 – Junos OS and Junos OS Evolved: PPMD goes into infinite loop upon receipt of malformed OSPF TLV
https://notcve.org/view.php?id=CVE-2022-22224
An Improper Check or Handling of Exceptional Conditions vulnerability in the processing of a malformed OSPF TLV in Juniper Networks Junos OS and Junos OS Evolved allows an unauthenticated adjacent attacker to cause the periodic packet management daemon (PPMD) process to go into an infinite loop, which in turn can cause protocols and functions reliant on PPMD such as OSPF neighbor reachability to be impacted, resulting in a sustained Denial of Service (DoS) condition. The DoS condition persists until the PPMD process is manually restarted. This issue affects: Juniper Networks Junos OS: All versions prior to 19.1R3-S9; 19.2 versions prior to 19.2R3-S5; 19.3 versions prior to 19.3R3-S3; 19.4 versions prior to 19.4R3-S9; 20.1 versions prior to 20.1R3; 20.2 versions prior to 20.2R3-S1; 20.3 versions prior to 20.3R3; 20.4 versions prior to 20.4R3; 21.1 versions prior to 21.1R2. Juniper Networks Junos OS Evolved: All versions prior to 20.4R3-S3-EVO; 21.1 versions prior to 21.1R2-EVO. Una vulnerabilidad de comprobación o administración inapropiada de condiciones excepcionales en el procesamiento de un TLV OSPF malformado en Juniper Networks Junos OS y Junos OS Evolved permite a un atacante adyacente no autenticado causar que el proceso del demonio de administración de paquetes periódicos (PPMD) entre en un bucle infinito, lo que a su vez puede causar que los protocolos y las funciones que dependen de PPMD, como la accesibilidad de los vecinos de OSPF, estén afectados, resultando en una condición de Denegación de Servicio (DoS) sostenida. • https://kb.juniper.net/JSA69874 • CWE-703: Improper Check or Handling of Exceptional Conditions •
