A Time-of-check Time-of-use (TOCTOU) Race Condition vulnerability in Routing Protocol Daemon (rpd) of Juniper Networks Junos OS, Junos OS Evolved allows a network-based unauthenticated attacker to cause a Denial of Service (DoS). When a BGP flow route with redirect IP extended community is received, and the reachability to the next-hop of the corresponding redirect IP is flapping, the rpd process might crash. Whether the crash occurs depends on the timing of the internally processing of these two events and is outside the attackers control. Please note that this issue also affects Route-Reflectors unless 'routing-options flow firewall-install-disable' is configured. This issue affects: Juniper Networks Junos OS: 18.4 versions prior to 18.4R2-S10, 18.4R3-S10; 19.1 versions prior to 19.1R3-S7; 19.2 versions prior to 19.2R1-S8, 19.2R3-S4; 19.4 versions prior to 19.4R3-S8; 20.2 versions prior to 20.2R3-S3; 20.3 versions prior to 20.3R3-S2; 20.4 versions prior to 20.4R3; 21.1 versions prior to 21.1R2. Juniper Networks Junos OS Evolved: All versions prior to 20.4R2-EVO; 21.1-EVO versions prior to 21.1R2-EVO. This issue does not affect Juniper Networks Junos OS versions prior to 18.4R1.

On QFX10000 Series devices using Juniper Networks Junos OS when configured as transit IP/MPLS penultimate hop popping (PHP) nodes with link aggregation group (LAG) interfaces, an Improper Validation of Specified Index, Position, or Offset in Input weakness allows an attacker sending certain IP packets to cause multiple interfaces in the LAG to detach causing a Denial of Service (DoS) condition. Continued receipt and processing of these packets will sustain the Denial of Service. This issue affects IPv4 and IPv6 packets. Packets of either type can cause and sustain the DoS event. These packets can be destined to the device or be transit packets. On devices such as the QFX10008 with line cards, line cards can be restarted to restore service. On devices such as the QFX10002 you can restart the PFE service, or reboot device to restore service. This issue affects: Juniper Networks Junos OS on QFX10000 Series: All versions prior to 15.1R7-S11; 18.4 versions prior to 18.4R2-S10, 18.4R3-S10; 19.1 versions prior to 19.1R3-S8; 19.2 versions prior to 19.2R3-S4; 19.3 versions prior to 19.3R3-S5; 19.4 versions prior to 19.4R2-S6, 19.4R3-S7; 20.1 versions prior to 20.1R3-S3; 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 21.1R3; 21.2 versions prior to 21.2R3-S3; 21.3 versions prior to 21.3R3-S1. An indicator of compromise may be seen by issuing the command: request pfe execute target fpc0 command "show jspec pechip[3] registers ps l2_node 10" timeout 0 | refresh 1 | no-more and reviewing for backpressured output; for example: GOT: 0x220702a8 pe.ps.l2_node[10].pkt_cnt 00000076 GOT: 0x220702b4 pe.ps.l2_node[10].backpressured 00000002 <<<< STICKS HERE and requesting detail on the pepic wanio: request pfe execute target fpc0 command "show pepic 0 wanio-info" timeout 0 | no-more | match xe-0/0/0:2 GOT: 3 xe-0/0/0:2 10 6 3 0 1 10 189 10 0x6321b088 <<< LOOK HERE as well as looking for tail drops looking at the interface queue, for example: show interfaces queue xe-0/0/0:2 resulting in: Transmitted: Total-dropped packets: 1094137 0 pps << LOOK HERE

An Improper Check or Handling of Exceptional Conditions vulnerability in the processing of a malformed OSPF TLV in Juniper Networks Junos OS and Junos OS Evolved allows an unauthenticated adjacent attacker to cause the periodic packet management daemon (PPMD) process to go into an infinite loop, which in turn can cause protocols and functions reliant on PPMD such as OSPF neighbor reachability to be impacted, resulting in a sustained Denial of Service (DoS) condition. The DoS condition persists until the PPMD process is manually restarted. This issue affects: Juniper Networks Junos OS: All versions prior to 19.1R3-S9; 19.2 versions prior to 19.2R3-S5; 19.3 versions prior to 19.3R3-S3; 19.4 versions prior to 19.4R3-S9; 20.1 versions prior to 20.1R3; 20.2 versions prior to 20.2R3-S1; 20.3 versions prior to 20.3R3; 20.4 versions prior to 20.4R3; 21.1 versions prior to 21.1R2. Juniper Networks Junos OS Evolved: All versions prior to 20.4R3-S3-EVO; 21.1 versions prior to 21.1R2-EVO.

A Time-of-check Time-of-use (TOCTOU) Race Condition vulnerability in the Routing Protocol Daemon (rpd) of Juniper Networks Junos OS and Junos OS Evolved allows an unauthenticated attacker with an established BGP session to cause a Denial of Service (DoS). In a BGP multipath scenario, when one of the contributing routes is flapping often and rapidly, rpd may crash. As this crash depends on whether a route is a contributing route, and on the internal timing of the events triggered by the flap this vulnerability is outside the direct control of a potential attacker. This issue affects: Juniper Networks Junos OS 19.2 versions prior to 19.2R3-S6; 20.2 versions prior to 20.2R3-S4; 20.3 versions prior to 20.3R3-S3; 20.4 versions prior to 20.4R3-S4; 21.1 versions prior to 21.1R3; 21.2 versions prior to 21.2R2; 21.3 versions prior to 21.3R2. Juniper Networks Junos OS Evolved All versions prior to 20.4R3-S4-EVO; 21.1-EVO version 21.1R1-EVO and later versions; 21.2-EVO versions prior to 21.2R2-EVO; 21.3-EVO versions prior to 21.3R2-EVO. This issue does not affect: Juniper Networks Junos OS versions 19.2 versions prior to 19.2R2, 19.3R1 and above prior to 20.2R1. Juniper Networks Junos OS Evolved versions prior to 20.2R1-EVO.

In VxLAN scenarios on EX4300-MP, EX4600, QFX5000 Series devices an Uncontrolled Memory Allocation vulnerability in the Packet Forwarding Engine (PFE) of Juniper Networks Junos OS allows an unauthenticated adjacently located attacker sending specific packets to cause a Denial of Service (DoS) condition by crashing one or more PFE's when they are received and processed by the device. Upon automatic restart of the PFE, continued processing of these packets will cause the memory leak to reappear. Depending on the volume of packets received the attacker may be able to create a sustained Denial of Service (DoS) condition. This issue affects: Juniper Networks Junos OS on EX4300-MP, EX4600, QFX5000 Series: 17.1 version 17.1R1 and later versions prior to 17.3R3-S12; 17.4 versions prior to 17.4R2-S13, 17.4R3-S5; 18.1 versions prior to 18.1R3-S13; 18.2 versions prior to 18.2R3-S8; 18.3 versions prior to 18.3R3-S5; 18.4 versions prior to 18.4R1-S8, 18.4R2-S6, 18.4R3-S6; 19.1 versions prior to 19.1R3-S4; 19.2 versions prior to 19.2R1-S7, 19.2R3-S1; 19.3 versions prior to 19.3R2-S6, 19.3R3-S1; 19.4 versions prior to 19.4R1-S4, 19.4R2-S4, 19.4R3-S1; 20.1 versions prior to 20.1R2; 20.2 versions prior to 20.2R2-S3, 20.2R3; 20.3 versions prior to 20.3R2. This issue does not affect Junos OS versions prior to 17.1R1.

An Improper Check for Unusual or Exceptional Conditions vulnerability in the Packet Forwarding Engine (PFE) of Juniper Networks Junos OS Evolved on ACX7000 Series allows an unauthenticated network-based attacker to cause a partial Denial of Service (DoS). On receipt of specific IPv6 transit traffic, Junos OS Evolved on ACX7100-48L, ACX7100-32C and ACX7509 sends this traffic to the Routing Engine (RE) instead of forwarding it, leading to increased CPU utilization of the RE and a partial DoS. This issue only affects systems configured with IPv6. This issue does not affect ACX7024 which is supported from 22.3R1-EVO onwards where the fix has already been incorporated as indicated in the solution section. This issue affects Juniper Networks Junos OS Evolved on ACX7100-48L, ACX7100-32C, ACX7509: 21.1-EVO versions prior to 21.1R3-S2-EVO; 21.2-EVO versions prior to 21.2R3-S2-EVO; 21.3-EVO versions prior to 21.3R3-EVO; 21.4-EVO versions prior to 21.4R1-S1-EVO, 21.4R2-EVO. This issue does not affect Juniper Networks Junos OS Evolved versions prior to 21.1R1-EVO.

ZGR TPS200 NG in its 2.00 firmware version and 1.01 hardware version, does not properly accept specially constructed requests. This allows an attacker with access to the network where the affected asset is located, to operate and change several parameters without having to be registered as a user on the web that owns the device.
