NUTUPS_CGI_SCRIPT_SELINUX(8)

💖 NAME 💖

okay so this page is nutups_cgi_script_selinux (section 8, bestie) and it's the Security Enhanced Linux Policy for the nutups_cgi_script processes. yes that's a lot of underscores. we love her anyway 🫶

---

✨ DESCRIPTION ✨

Security-Enhanced Linux secures the nutups_cgi_script processes via flexible mandatory access control. that's the whole point, and honestly? iconic.

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.

for example (copy-paste this, i know you want to):

ps -eZ | grep nutups_cgi_script_t

---

🚪 ENTRYPOINTS 🚪

The nutups_cgi_script_t SELinux type can be entered via the nutups_cgi_script_exec_t file type. that's the doorway, periodt.

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

---

👑 PROCESS TYPES 👑

SELinux defines process types (domains) for each process running on the system. yes, each one. she's thorough like that 💅

You can see the context of a process using the -Z option to ps.

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:

• nutups_cgi_script_t

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. so like, she stops blocking you, but she is still watching and taking notes 👀

---

🎀 BOOLEANS 🎀

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. tightest access possible, that's the aesthetic 🌸

• fips_mode — 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

• httpd_enable_cgi — if you want to allow httpd cgi support, you must turn on the httpd_enable_cgi boolean. Enabled by default.

setsebool -P httpd_enable_cgi 1

• nis_enabled — 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

• nscd_use_shm — 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

---

📂 MANAGED FILES 📂

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, so like, SELinux saying yes doesn't mean the UID said yes. two bouncers, bestie 🚪🚪

• nutups_cgi_rw_content_t

---

🗂️ FILE CONTEXTS 🗂️

SELinux requires files to have an extended attribute to define the file type. yes, files have labels too. main character energy for files 💅

You can see the context of a file using the -Z option to ls.

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.

⭐ STANDARD FILE CONTEXT ⭐

SELinux defines the file context types for the nutups_cgi_script. if you wanted to store files with these types in a different paths, you need to execute the semanage command to specify alternate labeling and then use restorecon to put the labels on disk. the way that labeling is a two-step process, honestly.

semanage fcontext -a -t nutups_cgi_script_exec_t '/srv/nutups_cgi_script/content(/.*)?'
restorecon -R -v /srv/mynutups_cgi_script_content

Note: SELinux often uses regular expressions to specify labels that match multiple files. that (/.*)? is not a typo, it's her being fancy ✨

The following file types are defined for nutups_cgi_script:

nutups_cgi_script_exec_t

• Set files with the nutups_cgi_script_exec_t type, if you want to transition an executable to the nutups_cgi_script_t domain.

Paths:

• /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. and then you will need to use restorecon to apply the labels. so chcon is the "it's just a phase" version and semanage fcontext + restorecon is the committed relationship 😭 don't get it twisted.

---

🧚 COMMANDS 🧚

• 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. yes, a GUI. for when the terminal is simply too much 🫶

okay that's the whole page bestie, you ate it 💅 this one's from nutups_cgi_script, dated 26-10-06, and the footer does that lil truncated-name thing: nutups_c...t_selinux(8). iconic of her tbh. byeee 🦋💖
