12 Jan 2023 — An Improper Check or Handling of Exceptional Conditions vulnerability in the IPsec library of Juniper Networks Junos OS allows a network-based, unauthenticated attacker to cause Denial of Service (DoS). On all MX platforms with MS-MPC or MS-MIC card, when specific IPv4 packets are processed by an IPsec6 tunnel, the Multiservices PIC Management Daemon (mspmand) process will core and restart. This will lead to FPC crash. Traffic flow is impacted while mspmand restarts. Continued receipt of these specific pack... • https://kb.juniper.net/JSA70209 • CWE-703: Improper Check or Handling of Exceptional Conditions •

18 Oct 2022 — 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 ... • https://kb.juniper.net/JSA69907 • CWE-664: Improper Control of a Resource Through its Lifetime •

18 Oct 2022 — 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_handle... • https://kb.juniper.net/JSA69906 • CWE-664: Improper Control of a Resource Through its Lifetime •

18 Oct 2022 — A PHP Local File Inclusion (LFI) vulnerability in the J-Web component of Juniper Networks Junos OS may allow a low-privileged authenticated attacker to execute an untrusted PHP file. By chaining this vulnerability with other unspecified vulnerabilities, and by circumventing existing attack requirements, successful exploitation could lead to a complete system compromise. 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.... • https://kb.juniper.net/JSA69899 • CWE-829: Inclusion of Functionality from Untrusted Control Sphere •

18 Oct 2022 — 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.
