captest
CAPTEST:(8) System Administration Utilities CAPTEST:(8)
NAME
captest - a program to demonstrate capabilities
SYNOPSIS
captest [ --drop-all | --drop-caps | --id ] [ --lock ] [ --text ]
DESCRIPTION
captest is a program that demonstrates and prints out the current process capabilities. Each option prints the same report. It will output
current capabilities. then it will try to access /etc/shadow directly to show if that can be done. Then it creates a child process that
attempts to read /etc/shadow and outputs the results of that. Then it outputs the capabilities that a child process would have.
You can also apply file system capabilities to this program to study how they work. For example, filecap /usr/bin/captest chown. Then run
captest as a normal user. Another interesting test is to make captest suid root so that you can see what the interaction is between root's
credentials and capabilities. For example, chmod 4755 /usr/bin/captest. When run as a normal user, the program will see if privilege esca-
lation is possible. But do not leave this app setuid root after you are don testing so that an attacker cannot take advantage of it.
OPTIONS
--drop-all
This drops all capabilities and clears the bounding set.
--drop-caps
This drops just traditional capabilities.
--id This changes to uid and gid 99, drops supplemental groups, and clears the bounding set.
--text This option outputs the effective capabilities in text rather than numerically.
--lock This prevents the ability for child processes to regain privileges if the uid is 0.
