Fix Recommendation

1. Open $DOMAIN_HOME/config/fmwconfig/components/OHS/<componentName>/httpd.conf with an editor.

2. Search for the "ThreadsPerChild" directive within "<IfModule mpm_worker_module>" directive at the OHS server configuration scope.

3. Within the "<IfModule mpm_worker_module>" directive, set the "ThreadsPerChild" directive to "25", add the directive if it does not exist.

4. Search for the "ThreadLimit" directive within "<IfModule mpm_worker_module>" directive at the OHS server configuration scope.

5. Within the "<IfModule mpm_worker_module>" directive, set the "ThreadLimit" directive to "64", add the directive if it does not exist.

Note: This vulnerability can be documented locally with the ISSM/ISSO if the site has operational reasons for the use of a higher value.

Check Contents

1. Open the $DOMAIN_HOME/config/fmwconfig/components/OHS/<componentName>/httpd.conf file with an editor.

2. Search for the "ThreadsPerChild" directive within "<IfModule mpm_worker_module>" directive at the OHS server configuration scope.

3. If "ThreadsPerChild" is omitted or set greater than "25", this is a finding.

4. Search for the "ThreadLimit" directive within "<IfModule mpm_worker_module>" directive at the OHS server configuration scope.

5. If "ThreadLimit" is omitted or set greater than "64", this is a finding.

Note: This vulnerability can be documented locally with the ISSM/ISSO if the site has operational reasons for the use of a higher value. If the site has this documentation, this should be marked as not a finding.
