OPENSSH LOCAL PRIVILEGE ESCALATION

OpenSSH Local Privilege Escalation Posted Dec 23, 2016 Authored by Jann Horn,
Google Security Research

OpenSSH can forward TCP sockets and UNIX domain sockets. If privilege separation
is disabled, then on the server side, the forwarding is handled by a child of
sshd that has root privileges. For TCP server sockets, sshd explicitly checks
whether an attempt is made to bind to a low port (below IPPORT_RESERVED) and, if
so, requires the client to authenticate as root. However, for UNIX domain
sockets, no such security measures are implemented. This means that, using "ssh
-L", an attacker who is permitted to log in as a normal user over SSH can
effectively connect to non-abstract unix domain sockets with root privileges. On
systems that run systemd, this can for example be exploited by asking systemd to
add an LD_PRELOAD environment variable for all following daemon launches and
then asking it to restart cron or so. The attached exploit demonstrates this -
if it is executed on a system with systemd where the user is allowed to ssh to
his own account and where privsep is disabled, it yields a root shell.
