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.

An Improper Handling of Exceptional Conditions vulnerability on specific PTX Series devices, including the PTX1000, PTX3000 (NextGen), PTX5000, PTX10002-60C, PTX10008, and PTX10016 Series, in Juniper Networks Junos OS allows an unauthenticated MPLS-based attacker to cause a Denial of Service (DoS) by triggering the dcpfe process to crash and FPC to restart. On affected PTX Series devices, processing specific MPLS packets received on an interface with multiple units configured may cause FPC to restart unexpectedly. Continued receipt and processing of this packet will create a sustained Denial of Service (DoS) condition. This issue only affects PTX Series devices utilizing specific FPCs found on PTX1000, PTX3000 (NextGen), PTX5000, PTX10002-60C, PTX10008, and PTX10016 Series devices, only if multiple units are configured on the ingress interface, and at least one unit has 'family mpls' *not* configured. See the configuration sample below for more information. No other platforms are affected by this vulnerability. This issue affects: Juniper Networks Junos OS on PTX Series: All versions prior to 19.1R3-S9; 19.2 versions prior to 19.2R3-S6; 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-S5; 20.3 versions prior to 20.3R3-S4; 20.4 versions prior to 20.4R3-S4; 21.1 versions prior to 21.1R3-S2; 21.2 versions prior to 21.2R3-S1; 21.3 versions prior to 21.3R3; 21.4 versions prior to 21.4R2; 22.1 versions prior to 22.1R2.

An Improper Input Validation vulnerability in the Packet Forwarding Engine (PFE) of Juniper Networks Junos OS and Junos OS Evolved allows an adjacent attacker to cause a PFE crash and thereby a Denial of Service (DoS). An FPC will crash and reboot after receiving a specific transit IPv6 packet over MPLS. Continued receipt of this packet will create a sustained Denial of Service (DoS) condition. This issue does not affect systems configured for IPv4 only. This issue affects: Juniper Networks Junos OS All versions prior to 12.3R12-S21; 15.1 versions prior to 15.1R7-S10; 17.3 versions prior to 17.3R3-S12; 18.3 versions prior to 18.3R3-S6; 18.4 versions prior to 18.4R2-S9, 18.4R3-S9; 19.1 versions prior to 19.1R2-S3, 19.1R3-S7; 19.2 versions prior to 19.2R1-S7, 19.2R3-S3; 19.3 versions prior to 19.3R2-S7, 19.3R3-S4; 19.4 versions prior to 19.4R3-S5; 20.1 versions prior to 20.1R3; 20.2 versions prior to 20.2R3-S2; 20.3 versions prior to 20.3R3; 20.4 versions prior to 20.4R2-S2, 20.4R3; 21.1 versions prior to 21.1R2.

A Missing Release of File Descriptor or Handle after Effective Lifetime vulnerability in plugable authentication module (PAM) of Juniper Networks Junos OS and Junos OS Evolved allows a locally authenticated attacker with low privileges to cause a Denial of Service (DoS). It is possible that after the termination of a gRPC connection the respective/var/run/<pid>.env file is not getting deleted which if occurring repeatedly can cause inode exhaustion. Inode exhaustion can present itself in two different ways: 1. The following log message can be observed: host kernel: pid <pid> (<process>), uid <uid> inumber <number> on /.mount/var: out of inodes which by itself is a clear indication. 2. The following log message can be observed: host <process>[<pid>]: ... : No space left on device which is not deterministic and just a representation of a write error which could have several reasons. So the following check needs to be done: user@host> show system storage no-forwarding Filesystem Size Used Avail Capacity Mounted on /dev/ada1p1 475M 300M 137M 69% /.mount/var which indicates that the write error is not actually due to a lack of disk space. If either 1. or 2. has been confirmed, then the output of: user@host> file list /var/run/*.env | count need to be checked and if it indicates a high (>10000) number of files the system has been affected by this issue. This issue affects: Juniper Networks Junos OS All versions prior to 19.1R3-S8; 19.2 versions prior to 19.2R3-S6; 19.3 versions prior to 19.3R3-S5; 19.4 versions prior to 19.4R2-S6, 19.4R3-S7; 20.1 version 20.1R1 and later versions; 20.2 versions prior to 20.2R3-S5; 20.3 versions prior to 20.3R3-S4; 20.4 versions prior to 20.4R3; 21.1 versions prior to 21.1R3; 21.2 versions prior to 21.2R2.

A Denial of Service (DoS) vulnerability in the processing of a flood of specific ARP traffic in Juniper Networks Junos OS on the EX4300 switch, sent from the local broadcast domain, may allow an unauthenticated network-adjacent attacker to trigger a PFEMAN watchdog timeout, causing the Packet Forwarding Engine (PFE) to crash and restart. After the restart, transit traffic will be temporarily interrupted until the PFE is reprogrammed. In a virtual chassis (VC), the impacted Flexible PIC Concentrator (FPC) may split from the VC temporarily, and join back into the VC once the PFE restarts. Continued receipt and processing of these packets will create a sustained Denial of Service (DoS) condition. This issue affects Juniper Networks Junos OS on the EX4300: All versions prior to 15.1R7-S12; 18.4 versions prior to 18.4R2-S10, 18.4R3-S11; 19.1 versions prior to 19.1R3-S8; 19.2 versions prior to 19.2R1-S9, 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-S1; 21.1 versions prior to 21.1R3; 21.2 versions prior to 21.2R2-S1, 21.2R3; 21.3 versions prior to 21.3R1-S2, 21.3R2.

Due to an Improper Initialization vulnerability in Juniper Networks Junos OS on EX4650 devices, packets received on the management interface (em0) but not destined to the device, may be improperly forwarded to an egress interface, instead of being discarded. Such traffic being sent by a client may appear genuine, but is non-standard in nature and should be considered as potentially malicious. This issue affects: Juniper Networks Junos OS on EX4650 Series: All versions prior to 19.1R3-S8; 19.2 versions prior to 19.2R3-S5; 19.3 versions prior to 19.3R3-S5; 19.4 versions prior to 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-S1; 21.2 versions prior to 21.2R3; 21.3 versions prior to 21.3R2; 21.4 versions prior to 21.4R2; 22.1 versions prior to 22.1R1.
