CVSS: 6.5EPSS: 0%CPEs: 80EXPL: 0CVE-2023-44196 – Junos OS Evolved: PTX10003 Series: Packets which are not destined to the router can reach the RE
https://notcve.org/view.php?id=CVE-2023-44196
An Improper Check for Unusual or Exceptional Conditions in the Packet Forwarding Engine (pfe) of Juniper Networks Junos OS Evolved on PTX10003 Series allows an unauthenticated adjacent attacker to cause an impact to the integrity of the system. When specific transit MPLS packets are received by the PFE, these packets are internally forwarded to the RE. This issue is a prerequisite for CVE-2023-44195. This issue affects Juniper Networks Junos OS Evolved: * All versions prior to 20.4R3-S8-EVO; * 21.1-EVO version 21.1R1-EVO and later; * 21.2-EVO versions prior to 21.2R3-S6-EVO; * 21.3-EVO version 21.3R1-EVO and later; * 21.4-EVO versions prior to 21.4R3-S3-EVO; * 22.1-EVO versions prior to 22.1R3-S4-EVO; * 22.2-EVO versions prior to 22.2R3-S3-EVO; * 22.3-EVO versions prior to 22.3R2-S2-EVO, 22.3R3-EVO; * 22.4-EVO versions prior to 22.4R2-EVO. Una Verificación Inadecuada de Condiciones Inusuales o Excepcionales en Packet Forwarding Engine (pfe) de Juniper Networks Junos OS Evolved en la serie PTX10003 permite que un atacante adyacente no autenticado cause un impacto en la integridad del sistema. Cuando el PFE recibe paquetes MPLS de tránsito específicos, estos paquetes se reenvían internamente al RE. Este problema es un requisito previo para CVE-2023-44195. • https://supportportal.juniper.net/JSA73162 • CWE-754: Improper Check for Unusual or Exceptional Conditions •
CVSS: 6.1EPSS: 0%CPEs: 42EXPL: 0CVE-2023-44189 – Junos OS Evolved: PTX10003 Series: MAC address validation bypass vulnerability
https://notcve.org/view.php?id=CVE-2023-44189
An Origin Validation vulnerability in MAC address validation of Juniper Networks Junos OS Evolved on PTX10003 Series allows a network-adjacent attacker to bypass MAC address checking, allowing MAC addresses not intended to reach the adjacent LAN to be forwarded to the downstream network. Due to this issue, the router will start forwarding traffic if a valid route is present in forwarding-table, causing a loop and congestion in the downstream layer-2 domain connected to the device. This issue affects Juniper Networks Junos OS Evolved on PTX10003 Series: * All versions prior to 21.4R3-S4-EVO; * 22.1 versions prior to 22.1R3-S3-EVO; * 22.2 version 22.2R1-EVO and later versions; * 22.3 versions prior to 22.3R2-S2-EVO, 22.3R3-S1-EVO; * 22.4 versions prior to 22.4R2-S1-EVO, 22.4R3-EVO; * 23.2 versions prior to 23.2R2-EVO. Una vulnerabilidad de validación de origen en la validación de direcciones MAC de Juniper Networks Junos OS Evolved en la serie PTX10003 permite que un atacante adyacente a la red omita la verificación de direcciones MAC, lo que permite que las direcciones MAC que no están destinadas a llegar a la LAN adyacente se reenvíen a la red descendente. Debido a este problema, el router comenzará a reenviar tráfico si hay una ruta válida en la tabla de reenvío, lo que provocará un bucle y una congestión en el dominio de capa 2 descendente conectado al dispositivo. Este problema afecta a Juniper Networks Junos OS Evolved en la serie PTX10003: * Todas las versiones anteriores a 21.4R3-S4-EVO; * Versiones 22.1 anteriores a 22.1R3-S3-EVO; * 22.2 versión 22.2R1-EVO y versiones posteriores; * Versiones 22.3 anteriores a 22.3R2-S2-EVO, 22.3R3-S1-EVO; * Versiones 22.4 anteriores a 22.4R2-S1-EVO, 22.4R3-EVO; * Versiones 23.2 anteriores a 23.2R2-EVO. • https://supportportal.juniper.net/JSA73153 • CWE-346: Origin Validation Error •
CVSS: 6.1EPSS: 0%CPEs: 31EXPL: 0CVE-2023-22397 – Junos OS Evolved: PTX10003: An attacker sending specific genuine packets will cause a memory leak in the PFE leading to a Denial of Service
https://notcve.org/view.php?id=CVE-2023-22397
An Allocation of Resources Without Limits or Throttling weakness in the memory management of the Packet Forwarding Engine (PFE) on Juniper Networks Junos OS Evolved PTX10003 Series devices allows an adjacently located attacker who has established certain preconditions and knowledge of the environment to send certain specific genuine packets to begin a Time-of-check Time-of-use (TOCTOU) Race Condition attack which will cause a memory leak to begin. Once this condition begins, and as long as the attacker is able to sustain the offending traffic, a Distributed Denial of Service (DDoS) event occurs. As a DDoS event, the offending packets sent by the attacker will continue to flow from one device to another as long as they are received and processed by any devices, ultimately causing a cascading outage to any vulnerable devices. Devices not vulnerable to the memory leak will process and forward the offending packet(s) to neighboring devices. Due to internal anti-flood security controls and mechanisms reaching their maximum limit of response in the worst-case scenario, all affected Junos OS Evolved devices will reboot in as little as 1.5 days. • https://kb.juniper.net/JSA70193 • CWE-367: Time-of-check Time-of-use (TOCTOU) Race Condition CWE-770: Allocation of Resources Without Limits or Throttling •
CVSS: 7.5EPSS: 0%CPEs: 57EXPL: 0CVE-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. This issue affects Juniper Networks Junos OS Evolved on PTX Series: All versions prior to 20.4R3-S4-EVO; 21.1-EVO version 21.1R1-EVO and later versions; 21.2-EVO version 21.2R1-EVO and later versions; 21.3-EVO versions prior to 21.3R3-EVO; 21.4-EVO versions prior to 21.4R2-EVO; 22.1-EVO versions prior to 22.1R2-EVO. • https://kb.juniper.net/JSA69916 • CWE-770: Allocation of Resources Without Limits or Throttling •
CVSS: 4.3EPSS: 0%CPEs: 319EXPL: 0CVE-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.
