CVSS: 7.5EPSS: 0%CPEs: 172EXPL: 0CVE-2023-22394 – Junos OS: SRX Series and MX Series: Memory leak due to receipt of specially crafted SIP calls
https://notcve.org/view.php?id=CVE-2023-22394
An Improper Handling of Unexpected Data Type vulnerability in the handling of SIP calls in Juniper Networks Junos OS on SRX Series and MX Series platforms allows an attacker to cause a memory leak leading to Denial of Services (DoS). This issue occurs on all MX Series platforms with MS-MPC or MS-MIC card and all SRX Series platforms where SIP ALG is enabled. Successful exploitation of this vulnerability prevents additional SIP calls and applications from succeeding. The SIP ALG needs to be enabled, either implicitly / by default or by way of configuration. To confirm whether SIP ALG is enabled on SRX use the following command: user@host> show security alg status | match sip SIP : Enabled This issue affects Juniper Networks Junos OS on SRX Series and on MX Series: All versions prior to 19.3R3-S7; 19.4 versions prior to 19.4R2-S8, 19.4R3-S10; 20.1 versions 20.1R1 and later versions; 20.2 versions prior to 20.2R3-S6; 20.3 versions prior to 20.3R3-S6; 20.4 versions prior to 20.4R3-S5; 21.1 versions prior to 21.1R3-S5; 21.2 versions prior to 21.2R3-S1; 21.3 versions prior to 21.3R3; 21.4 versions prior to 21.4R2-S2, 21.4R3; 22.1 versions prior to 22.1R1-S2, 22.1R2, 22.1R3-S1. • https://kb.juniper.net/JSA70190 • CWE-911: Improper Update of Reference Count •
CVSS: 7.5EPSS: 0%CPEs: 86EXPL: 0CVE-2023-22396 – Junos OS: Receipt of crafted TCP packets destined to the device results in MBUF leak leading to a Denial of Service (DoS)
https://notcve.org/view.php?id=CVE-2023-22396
An Uncontrolled Resource Consumption vulnerability in TCP processing on the Routing Engine (RE) of Juniper Networks Junos OS allows an unauthenticated network-based attacker to send crafted TCP packets destined to the device, resulting in an MBUF leak that ultimately leads to a Denial of Service (DoS). The system does not recover automatically and must be manually restarted to restore service. This issue occurs when crafted TCP packets are sent directly to a configured IPv4 or IPv6 interface on the device. Transit traffic will not trigger this issue. MBUF usage can be monitored through the use of the 'show system buffers' command. • https://kb.juniper.net/JSA70192 • CWE-400: Uncontrolled Resource Consumption •
CVSS: 6.5EPSS: 0%CPEs: 81EXPL: 0CVE-2023-22405 – Junos OS: QFX5k Series, EX46xx Series: MAC limiting feature stops working after PFE restart or device reboot
https://notcve.org/view.php?id=CVE-2023-22405
An Improper Preservation of Consistency Between Independent Representations of Shared State vulnerability in the Packet Forwarding Engine (PFE) of Juniper Networks Junos OS allows an adjacent, unauthenticated attacker to cause a Denial of Service (DoS) to device due to out of resources. When a device is configured with "service-provider/SP style" switching, and mac-limiting is configured on an Aggregated Ethernet (ae) interface, and then a PFE is restarted or the device is rebooted, mac-limiting doesn't work anymore. Please note that the issue might not be apparent as traffic will continue to flow through the device although the mac table and respective logs will indicate that mac limit is reached. Functionality can be restored by removing and re-adding the MAC limit configuration. This issue affects Juniper Networks Junos OS on QFX5k Series, EX46xx Series: All 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-S3; 21.2 versions prior to 21.2R3-S1; 21.3 versions prior to 21.3R3 on; 21.4 versions prior to 21.4R3 on; 22.1 versions prior to 22.1R2 on. • https://kb.juniper.net/JSA70201 • CWE-1250: Improper Preservation of Consistency Between Independent Representations of Shared State •
CVSS: 5.5EPSS: 0%CPEs: 193EXPL: 0CVE-2023-22398 – Junos OS and Junos OS Evolved: RPD might crash when MPLS ping is performed on BGP LSPs
https://notcve.org/view.php?id=CVE-2023-22398
An Access of Uninitialized Pointer 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). When an MPLS ping is performed on BGP LSPs, the RPD might crash. Repeated execution of this operation will lead to a sustained DoS. This issue affects: Juniper Networks Junos OS: 15.1 versions prior to 15.1R7-S12; 19.1 versions prior to 19.1R3-S9; 19.2 versions prior to 19.2R1-S9, 19.2R3-S5; 19.3 versions prior to 19.3R3-S6; 19.4 versions prior to 19.4R2-S7, 19.4R3-S8; 20.1 versions prior to 20.1R3-S4; 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 21.1R1-S1, 21.1R2; Juniper Networks Junos OS Evolved: All versions prior to 20.4R3-S4; 21.1 versions prior to 21.1R2-EVO. Una vulnerabilidad de acceso de puntero no inicializado en el demonio de protocolo de enrutamiento (rpd) de Juniper Networks Junos OS y Junos OS Evolved permite que un atacante autenticado localmente con privilegios bajos provoque una denegación de servicio (DoS). • https://kb.juniper.net/JSA70181 • CWE-824: Access of Uninitialized Pointer •
CVSS: 7.5EPSS: 0%CPEs: 142EXPL: 0CVE-2023-22411 – Junos OS: SRX Series: The flow processing daemon (flowd) will crash when Unified Policies are used with IPv6 and certain dynamic applications are rejected by the device
https://notcve.org/view.php?id=CVE-2023-22411
An Out-of-Bounds Write vulnerability in Flow Processing Daemon (flowd) of Juniper Networks Junos OS allows an unauthenticated, network-based attacker to cause Denial of Service (DoS). On SRX Series devices using Unified Policies with IPv6, when a specific IPv6 packet goes through a dynamic-application filter which will generate an ICMP deny message, the flowd core is observed and the PFE is restarted. This issue affects: Juniper Networks Junos OS on SRX Series: 19.2 versions prior to 19.2R3-S6; 19.3 versions prior to 19.3R3-S6; 19.4 versions prior to 19.4R3-S9; 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; 21.2 versions prior to 21.2R3; 21.3 versions prior to 21.3R2; 21.4 versions prior to 21.4R2. Una vulnerabilidad de escritura fuera de los límites en el Flow Processing Daemon (flowd) de Juniper Networks Junos OS permite que un atacante no autenticado basado en la red provoque una denegación de servicio (DoS). En los dispositivos de la serie SRX que utilizan políticas unificadas con IPv6, cuando un paquete IPv6 específico pasa por un filtro de aplicación dinámica que generará un mensaje de denegación de ICMP, se observa el núcleo fluido y se reinicia el PFE. • https://kb.juniper.net/JSA70207 • CWE-787: Out-of-bounds Write •
