nutups_cgi_script_selinux — Security Enhanced Linux Policy for the nutups_cgi_script processes
Security-Enhanced Linux secures the nutups_cgi_script processes via flexible mandatory access control.
The nutups_cgi_script processes execute with the nutups_cgi_script_t SELinux type. You can check if you have these processes running by executing the ps command with the -Z qualifier.
ps -eZ | grep nutups_cgi_script_t
The nutups_cgi_script_t SELinux type can be entered via the nutups_cgi_script_exec_t, shell_exec_t, nutups_cgi_script_exec_t file types.
The default entrypoint paths for the nutups_cgi_script_t domain are the following:
/var/www/nut-cgi-bin/upsset.cgi, /var/www/nut-cgi-bin/upsimage.cgi, /var/www/nut-cgi-bin/upsstats.cgi, /bin/d?ash, /bin/zsh.*, /bin/ksh.*, /usr/bin/d?ash, /usr/bin/zsh.*, /usr/bin/ksh.*, /bin/esh, /bin/mksh, /bin/sash, /bin/tcsh, /bin/yash, /bin/bash, /bin/fish, /bin/bash2, /usr/bin/esh, /usr/bin/tcsh, /usr/bin/yash, /usr/bin/sash, /usr/bin/mksh, /usr/bin/fish, /usr/bin/bash, /sbin/nologin, /usr/sbin/sesh, /usr/bin/bash2, /usr/sbin/smrsh, /usr/bin/scponly, /usr/sbin/nologin, /usr/libexec/sesh, /usr/sbin/scponlyc, /usr/bin/git-shell, /usr/bin/cockpit-bridge, /usr/libexec/git-core/git-shell, /var/www/nut-cgi-bin/upsset.cgi, /var/www/nut-cgi-bin/upsimage.cgi, /var/www/nut-cgi-bin/upsstats.cgi
SELinux defines process types (domains) for each process running on the system
You can see the context of a process using the -Z option to psbP
Policy governs the access confined processes have to files. SELinux nutups_cgi_script policy is very flexible allowing users to setup their nutups_cgi_script processes in as secure a method as possible.
The following process types are defined for nutups_cgi_script:
Note: semanage permissive -a nutups_cgi_script_t can be used to make the process type nutups_cgi_script_t permissive. SELinux does not deny access to permissive process types, but the AVC (SELinux denials) messages are still generated.
SELinux policy is customizable based on least access required. nutups_cgi_script policy is extremely flexible and has several booleans that allow you to manipulate the policy and run nutups_cgi_script with the tightest access possible.
If you want to deny any process from ptracing or debugging any other processes, you must turn on the deny_ptrace boolean. Enabled by default.
setsebool -P deny_ptrace 1
If you want to allow all domains to use other domains file descriptors, you must turn on the domain_fd_use boolean. Enabled by default.
setsebool -P domain_fd_use 1
If you want to allow all domains to have the kernel load modules, you must turn on the domain_kernel_load_modules boolean. Disabled by default.
setsebool -P domain_kernel_load_modules 1
If you want to allow all domains to execute in fips_mode, you must turn on the fips_mode boolean. Enabled by default.
setsebool -P fips_mode 1
If you want to enable reading of urandom for all domains, you must turn on the global_ssp boolean. Disabled by default.
setsebool -P global_ssp 1
If you want to allow httpd cgi support, you must turn on the httpd_enable_cgi boolean. Disabled by default.
setsebool -P httpd_enable_cgi 1
If you want to allow system to run with NIS, you must turn on the nis_enabled boolean. Disabled by default.
setsebool -P nis_enabled 1
If you want to allow confined applications to use nscd shared memory, you must turn on the nscd_use_shm boolean. Enabled by default.
setsebool -P nscd_use_shm 1
The SELinux process type nutups_cgi_script_t can manage files labeled with the following file types. The paths listed are the default paths for these file types. Note the processes UID still need to have DAC permissions.
SELinux requires files to have an extended attribute to define the file type.
You can see the context of a file using the -Z option to lsbP
Policy governs the access confined processes have to these files. SELinux nutups_cgi_script policy is very flexible allowing users to setup their nutups_cgi_script processes in as secure a method as possible.
The following file types are defined for nutups_cgi_script:
- Set files with the nutups_cgi_script_exec_t type, if you want to transition an executable to the nutups_cgi_script_t domain.
/var/www/nut-cgi-bin/upsset.cgi, /var/www/nut-cgi-bin/upsimage.cgi, /var/www/nut-cgi-bin/upsstats.cgi
Note: File context can be temporarily modified with the chcon command. If you want to permanently change the file context you need to use the semanage fcontext command. This will modify the SELinux labeling database. You will need to use restorecon to apply the labels.
semanage fcontext can also be used to manipulate default file context mappings.
semanage permissive can also be used to manipulate whether or not a process type is permissive.
semanage module can also be used to enable/disable/install/remove policy modules.
semanage boolean can also be used to manipulate the booleans
system-config-selinux is a GUI tool available to customize SELinux policy settings.
