CVE-2022-22211 – Junos OS Evolved: PTX Series: Multiple FPCs become unreachable due to continuous polling of specific SNMP OID
https://notcve.org/view.php?id=CVE-2022-22211
A limitless resource allocation vulnerability in FPC resources of Juniper Networks Junos OS Evolved on PTX Series allows an unprivileged attacker to cause Denial of Service (DoS). Continuously polling the SNMP jnxCosQstatTable causes the FPC to run out of GUID space, causing a Denial of Service to the FPC resources. When the FPC runs out of the GUID space, you will see the following syslog messages. The evo-aftmand-bt process is asserting. fpc1 evo-aftmand-bt[17556]: %USER-3: get_next_guid: Ran out of Guid Space start 1748051689472 end 1752346656767 fpc1 audit[17556]: %AUTH-5: ANOM_ABEND auid=4294967295 uid=0 gid=0 ses=4294967295 pid=17556 comm="EvoAftManBt-mai" exe="/usr/sbin/evo-aftmand-bt" sig=6 fpc1 kernel: %KERN-5: audit: type=1701 audit(1648567505.119:57): auid=4294967295 uid=0 gid=0 ses=4294967295 pid=17556 comm="EvoAftManBt-mai" exe="/usr/sbin/evo-aftmand-bt" sig=6 fpc1 emfd-fpa[14438]: %USER-5: Alarm set: APP color=red, class=CHASSIS, reason=Application evo-aftmand-bt fail on node Fpc1 fpc1 emfd-fpa[14438]: %USER-3-EMF_FPA_ALARM_REP: RaiseAlarm: Alarm(Location: /Chassis[0]/Fpc[1] Module: sysman Object: evo-aftmand-bt:0 Error: 2) reported fpc1 sysepochman[12738]: %USER-5-SYSTEM_REBOOT_EVENT: Reboot [node] [ungraceful reboot] [evo-aftmand-bt exited] The FPC resources can be monitored using the following commands: user@router> start shell [vrf:none] user@router-re0:~$ cli -c "show platform application-info allocations app evo-aftmand-bt" | grep ^fpc | grep -v Route | grep -i -v Nexthop | awk '{total[$1] += $5} END { for (key in total) { print key " " total[key]/4294967296 }}' Once the FPCs become unreachable they must be manually restarted as they do not self-recover.

CVE-2022-22208 – Junos OS and Junos OS Evolved: An rpd crash can occur due to memory corruption caused by flapping BGP sessions
https://notcve.org/view.php?id=CVE-2022-22208
A Use After Free vulnerability in the Routing Protocol Daemon (rdp) of Juniper Networks Junos OS and Junos OS Evolved allows an unauthenticated network-based attacker to cause Denial of Service (DoS). When a BGP session flap happens, a Use After Free of a memory location that was assigned to another object can occur, which will lead to an rpd crash. This is a race condition that is outside of the attacker's control and cannot be deterministically exploited. Continued flapping of BGP sessions can create a sustained Denial of Service (DoS) condition. This issue affects Juniper Networks Junos OS: All versions prior to 18.4R2-S9, 18.4R3-S11; 19.1 versions prior to 19.1R3-S8; 19.2 version 19.2R1 and later versions; 19.3 versions prior to 19.3R3-S5; 19.4 versions prior to 19.4R2-S6, 19.4R3-S6; 20.1 version 20.1R1 and later versions; 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-S3; 21.2 versions prior to 21.2R2-S1, 21.2R3. • https://kb.juniper.net/JSA69879 • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') CWE-416: Use After Free •
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 •
