Disable SSH Support for .rhosts Files
Medium Severity
SSH can emulate the behavior of the obsolete rsh command in allowing users to enable insecure access to their accounts via
.rhosts
files.
The default SSH configuration disables support for
.rhosts
. The appropriate configuration is used if no value is set for
IgnoreRhosts
.
To explicitly disable support for .rhosts files, add or correct the following line in
/etc/ssh/sshd_config
:
IgnoreRhosts yes
