CVSS: 7.5EPSS: 0%CPEs: 150EXPL: 1CVE-2023-22415 – Junos OS: MX Series and SRX Series: The flow processing daemon (flowd) will crash when specific H.323 packets are received
https://notcve.org/view.php?id=CVE-2023-22415
An Out-of-Bounds Write vulnerability in the H.323 ALG of Juniper Networks Junos OS allows an unauthenticated, network-based attacker to cause Denial of Service (DoS). On all MX Series and SRX Series platform, when H.323 ALG is enabled and specific H.323 packets are received simultaneously, a flow processing daemon (flowd) crash will occur. Continued receipt of these specific packets will cause a sustained Denial of Service (DoS) condition. This issue affects: Juniper Networks Junos OS on MX Series and SRX Series All versions prior to 19.4R3-S10; 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-S4; 21.2 versions prior to 21.2R3-S3; 21.3 versions prior to 21.3R3-S3; 21.4 versions prior to 21.4R3; 22.1 versions prior to 22.1R2-S1, 22.1R3; 22.2 versions prior to 22.2R1-S2, 22.2R2. Una vulnerabilidad de escritura fuera de los límites en el ALG H.323 de Juniper Networks Junos OS permite que un atacante basado en red no autenticado provoque una denegación de servicio (DoS). • https://kb.juniper.net/JSA70211 • CWE-787: Out-of-bounds Write •
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 •

https://notcve.org/view.php?id=CVE-2023-22404
An Out-of-bounds Write vulnerability in the Internet Key Exchange Protocol daemon (iked) of Juniper Networks Junos OS on SRX series and MX with SPC3 allows an authenticated, network-based attacker to cause a Denial of Service (DoS). iked will crash and restart, and the tunnel will not come up when a peer sends a specifically formatted payload during the negotiation. This will impact other IKE negotiations happening at the same time. Continued receipt of this specifically formatted payload will lead to continuous crashing of iked and thereby the inability for any IKE negotiations to take place. Note that this payload is only processed after the authentication has successfully completed. So the issue can only be exploited by an attacker who can successfully authenticate. • https://kb.juniper.net/JSA70200 • CWE-787: Out-of-bounds Write •
CVSS: 7.5EPSS: 0%CPEs: 63EXPL: 0CVE-2023-22408 – Junos OS: SRX 5000 Series: Upon processing of a specific SIP packet an FPC can crash
https://notcve.org/view.php?id=CVE-2023-22408
An Improper Validation of Array Index vulnerability in the SIP ALG of Juniper Networks Junos OS on SRX 5000 Series allows a network-based, unauthenticated attacker to cause a Denial of Service (DoS). When an attacker sends an SIP packets with a malformed SDP field then the SIP ALG can not process it which will lead to an FPC crash and restart. Continued receipt of these specific packets will lead to a sustained Denial of Service. This issue can only occur when both below mentioned conditions are fulfilled: 1. Call distribution needs to be enabled: [security alg sip enable-call-distribution] 2. • https://kb.juniper.net/JSA70204 • CWE-129: Improper Validation of Array Index •
CVSS: 7.5EPSS: 0%CPEs: 101EXPL: 0CVE-2023-22399 – Junos OS: QFX10K Series: PFE crash upon receipt of specific genuine packets when sFlow is enabled
https://notcve.org/view.php?id=CVE-2023-22399
When sFlow is enabled and it monitors a packet forwarded via ECMP, a buffer management vulnerability in the dcpfe process of Juniper Networks Junos OS on QFX10K Series systems allows an attacker to cause the Packet Forwarding Engine (PFE) to crash and restart by sending specific genuine packets to the device, resulting in a Denial of Service (DoS) condition. The dcpfe process tries to copy more data into a smaller buffer, which overflows and corrupts the buffer, causing a crash of the dcpfe process. Continued receipt and processing of these packets will create a sustained Denial of Service (DoS) condition. This issue affects Juniper Networks Junos OS on QFX10K Series: All versions prior to 19.4R3-S9; 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-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 22.1R2; 22.2 versions prior to 22.2R1-S2, 22.2R2. Cuando sFlow está habilitado y monitorea un paquete reenviado a través de ECMP, una vulnerabilidad de administración de búfer en el proceso dcpfe de Juniper Networks Junos OS en sistemas de la serie QFX10K permite a un atacante provocar que el motor de reenvío de paquetes (PFE) se bloquee y se reinicie mediante el envío de paquetes genuinos específicos. paquetes al dispositivo, lo que resulta en una condición de denegación de servicio (DoS). • https://kb.juniper.net/JSA70195 https://www.juniper.net/documentation/us/en/software/junos/network-mgmt/topics/topic-map/sflow-monitoring-technology.html • CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') •
