6 httpd_user_script_selinux - Security Enhanced Linux Policy for the
7 httpd_user_script processes
8
10 Security-Enhanced Linux secures the httpd_user_script processes via
11 flexible mandatory access control.
12 The httpd_user_script processes execute with the httpd_user_script_t
14 SELinux type. You can check if you have these processes running by exe‐
15 cuting the ps command with the -Z qualifier.
16 For example:
18 ps -eZ | grep httpd_user_script_t
20
24 The httpd_user_script_t SELinux type can be entered via the
25 httpd_user_script_exec_t, httpdcontent file types.
26 The default entrypoint paths for the httpd_user_script_t domain are the
28 following:
29 /home/[^/]+/((www)|(web)|(public_html))/cgi-bin(/.+)?
31
33 SELinux defines process types (domains) for each process running on the
34 system
35 You can see the context of a process using the -Z option to ps
37 Policy governs the access confined processes have to files. SELinux
39 httpd_user_script policy is very flexible allowing users to setup their
40 httpd_user_script processes in as secure a method as possible.
41 The following process types are defined for httpd_user_script:
43 httpd_user_script_t
45 Note: semanage permissive -a httpd_user_script_t can be used to make
47 the process type httpd_user_script_t permissive. SELinux does not deny
48 access to permissive process types, but the AVC (SELinux denials) mes‐
49 sages are still generated.
50
53 SELinux policy is customizable based on least access required.
54 httpd_user_script policy is extremely flexible and has several booleans
55 that allow you to manipulate the policy and run httpd_user_script with
56 the tightest access possible.
57 If you want to allow all domains to execute in fips_mode, you must turn
61 on the fips_mode boolean. Enabled by default.
62 setsebool -P fips_mode 1
64 If you want to allow httpd cgi support, you must turn on the httpd_en‐
68 able_cgi boolean. Enabled by default.
69 setsebool -P httpd_enable_cgi 1
71 If you want to allow httpd to read home directories, you must turn on
75 the httpd_enable_homedirs boolean. Disabled by default.
76 setsebool -P httpd_enable_homedirs 1
78 If you want to allow httpd to read user content, you must turn on the
82 httpd_read_user_content boolean. Disabled by default.
83 setsebool -P httpd_read_user_content 1
85 If you want to unify HTTPD handling of all content files, you must turn
89 on the httpd_unified boolean. Disabled by default.
90 setsebool -P httpd_unified 1
92 If you want to allow system to run with NIS, you must turn on the
96 nis_enabled boolean. Disabled by default.
97 setsebool -P nis_enabled 1

103 The SELinux process type httpd_user_script_t can manage files labeled
104 with the following file types. The paths listed are the default paths
105 for these file types. Note the processes UID still need to have DAC
106 permissions.
107 httpd_user_rw_content_t
109 krb5_host_rcache_t
112 /var/tmp/krb5_0.rcache2
114 /var/cache/krb5rcache(/.*)?
115 /var/tmp/nfs_0
116 /var/tmp/DNS_25
117 /var/tmp/host_0
118 /var/tmp/imap_0
119 /var/tmp/HTTP_23
120 /var/tmp/HTTP_48
121 /var/tmp/ldap_55
122 /var/tmp/ldap_487
123 /var/tmp/ldapmap1_0
124
127 SELinux requires files to have an extended attribute to define the file
128 type.
129 You can see the context of a file using the -Z option to ls
131 Policy governs the access confined processes have to these files.
133 SELinux httpd_user_script policy is very flexible allowing users to
134 setup their httpd_user_script processes in as secure a method as possi‐
135 ble.
136 STANDARD FILE CONTEXT
138 SELinux defines the file context types for the httpd_user_script, if
140 you wanted to store files with these types in a different paths, you
141 need to execute the semanage command to specify alternate labeling and
142 then use restorecon to put the labels on disk.
143 semanage fcontext -a -t httpd_user_script_exec_t
145 '/srv/httpd_user_script/content(/.*)?'
146 restorecon -R -v /srv/myhttpd_user_script_content
147 Note: SELinux often uses regular expressions to specify labels that
149 match multiple files.
150 The following file types are defined for httpd_user_script:
152 httpd_user_script_exec_t
156 - Set files with the httpd_user_script_exec_t type, if you want to
158 transition an executable to the httpd_user_script_t domain.
159 Note: File context can be temporarily modified with the chcon command.
163 If you want to permanently change the file context you need to use the
164 semanage fcontext command. This will modify the SELinux labeling data‐
165 base. You will need to use restorecon to apply the labels.
166
169 semanage fcontext can also be used to manipulate default file context
170 mappings.
171 semanage permissive can also be used to manipulate whether or not a
173 process type is permissive.
174 semanage module can also be used to enable/disable/install/remove pol‐
176 icy modules.
177 semanage boolean can also be used to manipulate the booleans
179 system-config-selinux is a GUI tool available to customize SELinux pol‐
182 icy settings.
