Test ID:	1.3.6.1.4.1.25623.1.0.10439
Category:	Gain root remotely
Title:	OpenSSH < 2.1.1 UseLogin feature
Summary:	NOSUMMARY
Description:	Description: You are running a version of OpenSSH which is older than 2.1.1. If the UseLogin option is enabled, then sshd does not switch to the uid of the user logging in. Instead, sshd relies on login(1) to do the job. However, if the user specifies a command for remote execution, login(1) cannot be used and sshd fails to set the correct user id, so the command is run with the same privilege as sshd (usually root privileges). *** Note that Nessus did not determine whether the UseLogin *** option was activated or not, so this message may *** be a false alarm Solution : Upgrade to OpenSSH 2.1.1 or make sure that the option UseLogin is set to no in sshd_config Risk factor : High
