CVE-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. Juniper Networks Junos OS Evolved All versions prior to 20.2R3-S3-EVO; 20.3-EVO version 20.3R1-EVO and later versions; 20.4-EVO versions prior to 20.4R3-S1-EVO; 21.1-EVO version 21.1R1-EVO and later versions; 21.2-EVO version 21.2R1-EVO and later versions; 21.3-EVO versions prior to 21.3R2-EVO. 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 •
CVE-2022-22237 – Junos OS: Peers not configured for TCP-AO can establish a BGP or LDP session even if authentication is configured locally
https://notcve.org/view.php?id=CVE-2022-22237
An Improper Authentication vulnerability in the kernel of Juniper Networks Junos OS allows an unauthenticated, network-based attacker to cause an impact on confidentiality or integrity. A vulnerability in the processing of TCP-AO will allow a BGP or LDP peer not configured with authentication to establish a session even if the peer is locally configured to use authentication. This could lead to untrusted or unauthorized sessions being established. This issue affects Juniper Networks Junos OS: 21.2 versions prior to 21.2R3-S1; 21.3 versions prior to 21.3R2-S2, 21.3R3; 21.4 versions prior to 21.4R2-S1, 21.4R3; 22.1 versions prior to 22.1R1-S1, 22.1R2. This issue does not affect Juniper Networks Junos OS Evolved. • https://kb.juniper.net/JSA69893 • CWE-287: Improper Authentication •
CVE-2022-22236 – Junos OS: SRX Series and MX Series: When specific valid SIP packets are received the PFE will crash
https://notcve.org/view.php?id=CVE-2022-22236
An Access of Uninitialized Pointer vulnerability in SIP Application Layer Gateway (ALG) of Juniper Networks Junos OS on SRX Series and MX Series allows an unauthenticated, network-based attacker to cause a Denial of Service (DoS). When specific valid SIP packets are received the PFE will crash and restart. This issue affects Juniper Networks Junos OS on SRX Series and MX Series: 20.4 versions prior to 20.4R3-S4; 21.1 versions prior to 21.1R3-S2; 21.2 versions prior to 21.2R3-S2; 21.3 versions prior to 21.3R2-S2, 21.3R3; 21.4 versions prior to 21.4R1-S2, 21.4R2; 22.1 versions prior to 22.1R1-S1, 22.1R2. This issue does not affect Juniper Networks Junos OS versions prior to 20.4R1. Una vulnerabilidad de acceso de puntero no inicializado en SIP Application Layer Gateway (ALG) de Juniper Networks Junos OS en las series SRX y MX permite a un atacante no autenticado y basado en la red causar una Denegación de Servicio (DoS). • https://kb.juniper.net/JSA69892 • CWE-824: Access of Uninitialized Pointer •
CVE-2022-22235 – Junos OS: SRX Series: A flowd core will be observed when malformed GPRS traffic is processed
https://notcve.org/view.php?id=CVE-2022-22235
An Improper Check for Unusual or Exceptional Conditions vulnerability in the Packet Forwarding Engine (PFE) of Juniper Networks Junos OS on SRX Series allows an unauthenticated, network-based, attacker to cause Denial of Service (DoS). A PFE crash will happen when a GPRS Tunnel Protocol (GTP) packet is received with a malformed field in the IP header of GTP encapsulated General Packet Radio Services (GPRS) traffic. The packet needs to match existing state which is outside the attackers control, so the issue cannot be directly exploited. The issue will only be observed when endpoint address validation is enabled. This issue affects Juniper Networks Junos OS on SRX Series: 20.2 versions prior to 20.2R3-S5; 20.3 versions prior to 20.3R3-S4; 20.4 versions prior to 20.4R3-S3; 21.1 versions prior to 21.1R3-S2; 21.2 versions prior to 21.2R3-S1; 21.3 versions prior to 21.3R3; 21.4 versions prior to 21.4R1-S2, 21.4R2; 22.1 versions prior to 22.1R1-S1, 22.1R2. • https://kb.juniper.net/JSA69891 • CWE-754: Improper Check for Unusual or Exceptional Conditions •
CVE-2022-22234 – Junos OS: EX2300 and EX3400 Series: One of more SFPs might become unavailable when the system is very busy
https://notcve.org/view.php?id=CVE-2022-22234
An Improper Preservation of Consistency Between Independent Representations of Shared State vulnerability in the Packet Forwarding Engine (PFE) of Juniper Networks Junos OS allows a locally authenticated attacker with low privileges to cause a Denial of Service (DoS). If the device is very busy for example while executing a series of show commands on the CLI one or more SFPs might not be detected anymore. The system then changes its state to "unplugged" which is leading to traffic impact and at least a partial DoS. Once the system is less busy the port states return to their actual value. Indicators of compromise are log messages about unplugged SFPs and corresponding syspld messages without any physical or environmental cause. • https://kb.juniper.net/JSA69890 • CWE-1250: Improper Preservation of Consistency Between Independent Representations of Shared State •
