Description An Improper Restriction of Operations within the Bounds of a Memory Buffer issue in the management daemon (mgd) process of Juniper Networks Junos OS and Junos OS Evolved allows a network-based authenticated low-privileged attacker to cause a CPU Denial of Service to the device's control plane by executing a specific command via NETCONF. An indicator of compromise can be seen by determining if the NETCONF client is logged in and fails to log out after a reasonable period of time and reviewing the WCPU percentage for the mgd process.
