Detail
An Improper Restriction of Operations within the Bounds of a Memory Buffer vulnerability in the management daemon (mgd) process of Juniper Networks Junos OS and Junos OS Evolved allows a network-based authenticated low-privileged attacker, by executing a specific command via NETCONF, to cause a CPU Denial of Service to the device's control plane. This issue affects: Juniper Networks Junos OS * All versions prior to 20.4R3-S7; Juniper Networks Junos OS Evolved * All versions prior to 21.4R3-S4-EVO; An indicator of compromise can be seen by first determining if the NETCONF client is logged in and fails to log out after a reasonable period of time and secondly reviewing the WCPU percentage for the mgd process by running the following command: mgd process example: user@device-re#> show system processes extensive | match "mgd|PID" | except last PID USERNAME PRI NICE SIZE RES STATE C TIME WCPU COMMAND 92476 root 100 0 500M 89024K CPU3 3 57.5H 89.60% mgd <<<<<<<<<<< review the high cpu percentage. Example to check for NETCONF activity: While there is no specific command that shows a specific session in use for NETCONF, you can review logs for UI_LOG_EVENT with "client-mode 'netconf'" For example: mgd[38121]: UI_LOGIN_EVENT: User 'root' login, class 'super-user' [38121], ssh-connection '10.1.1.1 201 55480 10.1.1.2 22', client-mode 'netconf' |
