CVE-2022-22201 – SRX5000 Series with SPC3, SRX4000 Series, and vSRX: When PowerMode IPsec is configured, the PFE will crash upon receipt of a malformed ESP packet

https://notcve.org/view.php?id=CVE-2022-22201

An Improper Validation of Specified Index, Position, or Offset in Input vulnerability in the Packet Forwarding Engine (PFE) of Juniper Networks Junos OS allows an unauthenticated network-based attacker to cause a Denial of Service (DoS). On SRX5000 Series with SPC3, SRX4000 Series, and vSRX, when PowerMode IPsec is configured and a malformed ESP packet matching an established IPsec tunnel is received the PFE crashes. This issue affects Juniper Networks Junos OS on SRX5000 Series with SPC3, SRX4000 Series, and vSRX: All versions prior to 19.4R2-S6, 19.4R3-S7; 20.1 versions prior to 20.1R3-S3; 20.2 versions prior to 20.2R3-S4; 20.3 versions prior to 20.3R3-S3; 20.4 versions prior to 20.4R3-S2; 21.1 versions prior to 21.1R3; 21.2 versions prior to 21.2R3; 21.3 versions prior to 21.3R1-S2, 21.3R2. Una vulnerabilidad de comprobación inapropiada del índice, la posición o el desplazamiento especificados en la entrada en Packet Forwarding Engine (PFE) de Juniper Networks Junos OS permite a un atacante no autenticado basado en la red causar una Denegación de Servicio (DoS). En las series SRX5000 con SPC3, SRX4000 y vSRX, cuando es configurado PowerMode IPsec y es recibido un paquete ESP malformado que coincide con un túnel IPsec establecido, el PFE es bloqueado. • https://kb.juniper.net/JSA69900 • CWE-20: Improper Input Validation CWE-1285: Improper Validation of Specified Index, Position, or Offset in Input •

CVE-2022-22192 – Junos OS Evolved: PTX Series: An attacker can cause a kernel panic by sending a malformed TCP packet to the device

https://notcve.org/view.php?id=CVE-2022-22192

An Improper Validation of Syntactic Correctness of Input vulnerability in the kernel of Juniper Networks Junos OS Evolved on PTX series allows a network-based, unauthenticated attacker to cause a Denial of Service (DoS). When an incoming TCP packet destined to the device is malformed there is a possibility of a kernel panic. Only TCP packets destined to the ports for BGP, LDP and MSDP can trigger this. This issue only affects PTX10004, PTX10008, PTX10016. No other PTX Series devices or other platforms are affected. • https://kb.juniper.net/JSA69915 • CWE-20: Improper Input Validation CWE-1286: Improper Validation of Syntactic Correctness of Input •

CVE-2022-22221 – Junos OS: SRX and EX Series: Local privilege escalation flaw in "download" functionality

https://notcve.org/view.php?id=CVE-2022-22221

An Improper Neutralization of Special Elements vulnerability in the download manager of Juniper Networks Junos OS on SRX Series and EX Series allows a locally authenticated attacker with low privileges to take full control over the device. One aspect of this vulnerability is that the attacker needs to be able to execute any of the "request ..." or "show system download ..." commands. This issue affects Juniper Networks Junos OS on SRX Series and EX Series: All versions prior to 19.2R1-S9, 19.2R3-S5; 19.3 versions prior to 19.3R3-S6; 19.4 versions prior to 19.4R3-S8; 20.1 versions prior to 20.1R3-S4; 20.2 versions prior to 20.2R3-S4; 20.3 versions prior to 20.3R3-S3; 20.4 versions prior to 20.4R3-S2, 20.4R3-S3; 21.1 versions prior to 21.1R3-S1; 21.2 versions prior to 21.2R2-S2, 21.2R3; 21.3 versions prior to 21.3R2, 21.3R3; 21.4 versions prior to 21.4R1-S1, 21.4R2. Una vulnerabilidad de Neutralización Inapropiada de Elementos Especiales en el administrador de descargas del Sistema Operativo Junos de Juniper Networks en las series SRX y EX permite a un atacante autenticado localmente con bajos privilegios tomar el control total del dispositivo. Uno de los aspectos de esta vulnerabilidad es que el atacante debe ser capaz de ejecutar cualquiera de los comandos "request ..." o "show system download ...". • https://kb.juniper.net/JSA69725 •

CVE-2022-22217 – Junos OS: QFX10K Series: Denial of Service (DoS) upon receipt of crafted MLD packets on multi-homing ESI in VXLAN

https://notcve.org/view.php?id=CVE-2022-22217

An Improper Check for Unusual or Exceptional Conditions vulnerability in the Packet Forwarding Engine (PFE) of Juniper Networks Junos OS allows an adjacent unauthenticated attacker to cause a Denial of Service (DoS). The issue is caused by malformed MLD packets looping on a multi-homed Ethernet Segment Identifier (ESI) when VXLAN is configured. These MLD packets received on a multi-homed ESI are sent to the peer, and then incorrectly forwarded out the same ESI, violating the split horizon rule. This issue only affects QFX10K Series switches, including the QFX10002, QFX10008, and QFX10016. Other products and platforms are unaffected by this vulnerability. • https://kb.juniper.net/JSA69721 • CWE-754: Improper Check for Unusual or Exceptional Conditions •

CVE-2022-22216 – Junos OS: PTX Series and QFX10000 Series: 'Etherleak' memory disclosure in Ethernet padding data

https://notcve.org/view.php?id=CVE-2022-22216

An Exposure of Sensitive Information to an Unauthorized Actor vulnerability in the PFE of Juniper Networks Junos OS on PTX Series and QFX10k Series allows an adjacent unauthenticated attacker to gain access to sensitive information. PTX1000 and PTX10000 Series, and QFX10000 Series and PTX5000 Series devices sometimes do not reliably pad Ethernet packets, and thus some packets can contain fragments of system memory or data from previous packets. This issue is also known as 'Etherleak' and often detected as CVE-2003-0001. This issue affects: Juniper Networks Junos OS on PTX1000 and PTX10000 Series: All versions prior to 18.4R3-S11; 19.1 versions prior to 19.1R2-S3, 19.1R3-S7; 19.2 versions prior to 19.2R1-S8, 19.2R3-S4; 19.3 versions prior to 19.3R3-S4; 19.4 versions prior to 19.4R2-S5, 19.4R3-S6; 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-S4; 21.1 versions prior to 21.1R2-S1, 21.1R3; 21.2 versions prior to 21.2R1-S1, 21.2R2. Juniper Networks Junos OS on QFX10000 Series and PTX5000 Series: All versions prior to 18.3R3-S6; 18.4 versions prior to 18.4R2-S9, 18.4R3-S10; 19.1 versions prior to 19.1R2-S3, 19.1R3-S7; 19.2 versions prior to 19.2R1-S8, 19.2R3-S4; 19.3 versions prior to 19.3R3-S4; 19.4 versions prior to 19.4R2-S6, 19.4R3-S6; 20.1 versions prior to 20.1R3-S2; 20.2 versions prior to 20.2R3-S3; 20.3 versions prior to 20.3R3-S1; 20.4 versions prior to 20.4R3-S1; 21.1 versions prior to 21.1R2-S1, 21.1R3; 21.2 versions prior to 21.2R2. • https://kb.juniper.net/JSA69720 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •
