# Exploiting D-Bus and Socket Command Injection
## When to Use
- During authorized local privilege escalation on desktop/server Linux that runs the D-Bus system bus
- When a root-owned service exposes a D-Bus interface with an unprivileged-callable method
- When `linpeas`/manual enumeration finds root-owned UNIX sockets in `/tmp`, `/run`, or abstract namespace
- When custom or vendor IPC daemons accept untrusted input and perform privileged actions
- When reviewing D-Bus policy (`/etc/dbus-1/system.d/`) and Polkit action authorization
## Critical: Techniques Most Often Missed
D-Bus and socket privesc is overlooked because the methods aren't visible in a port scan. Enumerate the bus and local sockets explicitly.
