cyberstrikeus 5.1.3 Ensure rsh client is not installed (Scored)
Profile Applicability
- Level 1
Description
The rsh package contains the client commands for the rsh services.
Rationale
These legacy clients contain numerous security exposures and have been replaced with the more secure SSH package. Even if the server is removed, it is best to ensure the clients are also removed to prevent users from inadvertently attempting to use these commands and therefore exposing their credentials. Note that removing the rsh package removes the clients for rsh, rcp and rlogin.
Audit Procedure
Using Command Line
Run the following commands:
dpkg -s rsh-client
dpkg -s rsh-redone-client
Expected Result
Ensure package status is not-installed or dpkg returns no info is available for both.
Remediation
Using Command Line
Uninstall the rsh-client and rsh-reload-client packages:
apt-get purge rsh-client rsh-reload-client
Default Value
Not installed by default on Ubuntu 12.04 LTS Server.
