Juniper:  >> Junos  Security Vulnerabilities
A Path Traversal vulnerability in the J-Web component of Juniper Networks Junos OS allows an authenticated attacker to upload arbitrary files to the device by bypassing validation checks built into Junos OS. The attacker should not be able to execute the file due to validation checks built into Junos OS. Successful exploitation of this vulnerability could lead to loss of filesystem integrity. This issue affects Juniper Networks Junos OS: all versions prior to 19.1R3-S9; 19.2 versions prior to 19.2R3-S6; 19.3 versions prior to 19.3R3-S7; 19.4 versions prior to 19.4R3-S9; 20.1 versions prior to 20.1R3-S5; 20.2 versions prior to 20.2R3-S5; 20.3 versions prior to 20.3R3-S5; 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 21.3R2-S2, 21.3R3; 21.4 versions prior to 21.4R1-S2, 21.4R2-S1, 21.4R3; 22.1 versions prior to 22.1R1-S1, 22.1R2.

An Improper Control of a Resource Through its Lifetime vulnerability in the Packet Forwarding Engine (PFE) of Juniper Networks Junos OS on MX Series allows an unauthenticated adjacent attacker to cause a Denial of Service (DoS). When there is a continuous mac move a memory corruption causes one or more FPCs to crash and reboot. These MAC moves can be between two local interfaces or between core/EVPN and local interface. The below error logs can be seen in PFE syslog when this issue happens: xss_event_handler(1071): EA[0:0]_PPE 46.xss[0] ADDR Error. ppe_error_interrupt(4298): EA[0:0]_PPE 46 Errors sync xtxn error xss_event_handler(1071): EA[0:0]_PPE 1.xss[0] ADDR Error. ppe_error_interrupt(4298): EA[0:0]_PPE 1 Errors sync xtxn error xss_event_handler(1071): EA[0:0]_PPE 2.xss[0] ADDR Error.

An Improper Control of a Resource Through its Lifetime vulnerability in Packet Forwarding Engine (PFE) of Juniper Networks Junos OS and Junos OS Evolved allows unauthenticated adjacent attacker to cause a Denial of Service (DoS). In an EVPN-MPLS scenario, if MAC is learned locally on an access interface but later a request to delete is received indicating that the MAC was learnt remotely, this can lead to memory corruption which can result in line card crash and reload. This issue affects: Juniper Networks Junos OS All versions 17.3R1 and later versions prior to 19.2R3-S5; 19.3 versions prior to 19.3R3-S5; 19.4 versions prior to 19.4R2-S6, 19.4R3-S8; 20.1 version 20.1R1 and later versions; 20.2 versions prior to 20.2R3-S4; 20.3 versions prior to 20.3R3-S3; 20.4 versions prior to 20.4R3-S3; 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 21.4R1-S1, 21.4R2. Juniper Networks Junos OS Evolved All versions prior to 20.4R3-S3-EVO; 21.1-EVO version 21.1R1-EVO and later versions; 21.2-EVO versions prior to 21.2R3-EVO; 21.3-EVO versions prior to 21.3R2-EVO; 21.4-EVO versions prior to 21.4R1-S1-EVO, 21.4R2-EVO.

An Improper Input Validation vulnerability in the Routing Protocol Daemon (rpd) of Juniper Networks Junos OS and Junos OS Evolved allows an adjacent unauthenticated attacker to cause DoS (Denial of Service). If another router generates more than one specific valid OSPFv3 LSA then rpd will crash while processing these LSAs. This issue only affects systems configured with OSPFv3, while OSPFv2 is not affected. This issue affects: Juniper Networks Junos OS 19.2 versions prior to 19.2R3-S6; 19.3 version 19.3R2 and later versions; 19.4 versions prior to 19.4R2-S8, 19.4R3-S9; 20.1 version 20.1R1 and later versions; 20.2 versions prior to 20.2R3-S5; 20.3 versions prior to 20.3R3-S5; 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-S2; 21.4 versions prior to 21.4R2.
