Description of problem:
The problem happens when an user tries to scan and remediate a system with OSPP pprofile if Tmux package is not installed. There is a rule package_tmux_installed which checks for the Tmux package and if it is not presents, it installs it. During this phase the line
/bin/tmux
is added into the /etc/shells.
Then there is a rule no_tmux_in_shells which checks for presence of a line containing tmux in /etc/shells.
What happens:
1. system is scanned. package_tmux_installed fails. no_tmux_in_shells passes.
2. remediation phase is performed. Remediation for package_tmux_installed is performed, effectively adding it into /etc/shells.
3. System is again scanned. package_tmux_installed passes but no_tmux_in_shells fails this time.
Version-Release number of selected component (if applicable):
scap-security-guide-0.1.46-2.el8.noarch
How reproducible:
always
Steps to Reproduce:
1. Install a rhel8 system, make sure that the package Tmux is not installed. Install openscap-scanner and scap-security-guide.
2. run
`oscap xccdf eval --remediate --profile=ospp /usr/share/xml/scap/ssg/content/ssg-rhel8-ds.xml`
This scans and remediates the OSPP profile.
3. Now run
`oscap xccdf eval --profile=ospp --rule=xccdf_org.ssgproject.content_rule_no_tmux_in_shells /usr/share/xml/scap/ssg/content/ssg-rhel8-ds.xml`
This only scans the system.
