https://notcve.org/view.php?id=CVE-2023-28983
An OS Command Injection vulnerability in gRPC Network Operations Interface (gNOI) server module of Juniper Networks Junos OS Evolved allows an authenticated, low privileged, network based attacker to inject shell commands and execute code. This issue affects Juniper Networks Junos OS Evolved 21.4 version 21.4R1-EVO and later versions prior to 22.1R1-EVO. • https://supportportal.juniper.net/JSA70609 • CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') •
CVSS: 7.5EPSS: 0%CPEs: 47EXPL: 0CVE-2023-22393 – Junos OS and Junos OS Evolved: RPD crash upon receipt of BGP route with invalid next-hop
https://notcve.org/view.php?id=CVE-2023-22393
An Improper Check for Unusual or Exceptional Conditions vulnerability in BGP route processing of Juniper Networks Junos OS and Junos OS Evolved allows an attacker to cause Routing Protocol Daemon (RPD) crash by sending a BGP route with invalid next-hop resulting in a Denial of Service (DoS). Continued receipt and processing of this packet will create a sustained Denial of Service (DoS) condition. This issue only affects systems without import policy configured. This issue affects: Juniper Networks Junos OS 21.1 versions prior to 21.1R3-S4; 21.2 versions prior to 21.2R3-S3; 21.3 versions prior to 21.3R3-S2; 21.4 versions prior to 21.4R2-S2, 21.4R3; 22.1 versions prior to 22.1R1-S2, 22.1R2; 22.2 versions prior to 22.2R1-S1, 22.2R2. Juniper Networks Junos OS Evolved 21.4-EVO versions prior to 21.4R2-S2-EVO, 21.4R3-EVO; 22.1-EVO versions prior to 22.1R1-S2-EVO, 22.1R2-EVO; 22.2-EVO versions prior to 22.2R1-S1-EVO, 22.2R2-EVO. • https://kb.juniper.net/JSA70189 • CWE-358: Improperly Implemented Security Check for Standard CWE-754: Improper Check for Unusual or Exceptional Conditions •
CVSS: 5.9EPSS: 0%CPEs: 14EXPL: 0CVE-2023-22402 – Junos OS Evolved: The kernel might restart in a BGP scenario where "bgp auto-discovery" is enabled and such a neighbor flaps
https://notcve.org/view.php?id=CVE-2023-22402
A Use After Free vulnerability in the kernel of Juniper Networks Junos OS Evolved allows an unauthenticated, network-based attacker to cause a Denial of Service (DoS). In a Non Stop Routing (NSR) scenario, an unexpected kernel restart might be observed if "bgp auto-discovery" is enabled and if there is a BGP neighbor flap of auto-discovery sessions for any reason. This is a race condition which is outside of an attackers direct control and it depends on system internal timing whether this issue occurs. This issue affects Juniper Networks Junos OS Evolved: 21.3 versions prior to 21.3R3-EVO; 21.4 versions prior to 21.4R2-EVO; 22.1 versions prior to 22.1R2-EVO; 22.2 versions prior to 22.2R1-S1-EVO, 22.2R2-EVO. Una vulnerabilidad Use-After-Free en el núcleo de Juniper Networks Junos OS Evolved permite que un atacante no autenticado basado en la red provoque una denegación de servicio (DoS). • https://kb.juniper.net/JSA70198 • CWE-416: Use After Free •
CVSS: 7.5EPSS: 0%CPEs: 11EXPL: 0CVE-2023-22401 – Junos OS and Junos OS Evolved: PTX10008, PTX10016: When a specific SNMP MIB is queried the FPC will crash
https://notcve.org/view.php?id=CVE-2023-22401
An Improper Validation of Array Index vulnerability in the Advanced Forwarding Toolkit Manager daemon (aftmand) of Juniper Networks Junos OS and Junos OS Evolved allows an unauthenticated, network-based attacker to cause a Denial of Service (DoS). On the PTX10008 and PTX10016 platforms running Junos OS or Junos OS Evolved, when a specific SNMP MIB is queried this will cause a PFE crash and the FPC will go offline and not automatically recover. A system restart is required to get the affected FPC in an operational state again. This issue affects: Juniper Networks Junos OS 22.1 version 22.1R2 and later versions; 22.1 versions prior to 22.1R3; 22.2 versions prior to 22.2R2. Juniper Networks Junos OS Evolved 21.3-EVO version 21.3R3-EVO and later versions; 21.4-EVO version 21.4R1-S2-EVO, 21.4R2-EVO and later versions prior to 21.4R2-S1-EVO; 22.1-EVO version 22.1R2-EVO and later versions prior to 22.1R3-EVO; 22.2-EVO versions prior to 22.2R1-S1-EVO, 22.2R2-EVO. • https://kb.juniper.net/JSA70197 • CWE-129: Improper Validation of Array Index •
CVSS: 7.5EPSS: 0%CPEs: 37EXPL: 0CVE-2023-22400 – Junos OS Evolved: A specific SNMP GET operation and a specific CLI commands cause resources to leak and eventually the evo-pfemand process will crash
https://notcve.org/view.php?id=CVE-2023-22400
An Uncontrolled Resource Consumption vulnerability in the PFE management daemon (evo-pfemand) of Juniper Networks Junos OS Evolved allows an unauthenticated, network-based attacker to cause an FPC crash leading to a Denial of Service (DoS). When a specific SNMP GET operation or a specific CLI command is executed this will cause a GUID resource leak, eventually leading to exhaustion and result in an FPC crash and reboot. GUID exhaustion will trigger a syslog message like one of the following for example: evo-pfemand[<pid>]: get_next_guid: Ran out of Guid Space ... evo-aftmand-zx[<pid>]: get_next_guid: Ran out of Guid Space ... This leak can be monitored by running the following command and taking note of the value in the rightmost column labeled Guids: user@host> show platform application-info allocations app evo-pfemand | match "IFDId|IFLId|Context" Node Application Context Name Live Allocs Fails Guids re0 evo-pfemand net::juniper::interfaces::IFDId 0 3448 0 3448 re0 evo-pfemand net::juniper::interfaces::IFLId 0 561 0 561 user@host> show platform application-info allocations app evo-pfemand | match "IFDId|IFLId|Context" Node Application Context Name Live Allocs Fails Guids re0 evo-pfemand net::juniper::interfaces::IFDId 0 3784 0 3784 re0 evo-pfemand net::juniper::interfaces::IFLId 0 647 0 647 This issue affects Juniper Networks Junos OS Evolved: All versions prior to 20.4R3-S3-EVO; 21.1-EVO version 21.1R1-EVO and later versions; 21.2-EVO versions prior to 21.2R3-S4-EVO; 21.3-EVO version 21.3R1-EVO and later versions; 21.4-EVO versions prior to 21.4R2-EVO.
