CVE-2025-59961
Junos OS and Junos OS Evolved: Unix socket used to control the jdhcpd process is world-writable
An Incorrect Permission Assignment for Critical Resource vulnerability in the Juniper DHCP daemon (jdhcpd) of Juniper Networks Junos OS and Junos OS Evolved allows a local, low-privileged user to write to the Unix socket used to manage the jdhcpd process, resulting in complete control over the resource.
This vulnerability allows any low-privileged user logged into the system to connect to the Unix socket and issue commands to manage the DHCP service, in essence, taking administrative control of the local DHCP server or DHCP relay.
