Title

Web server system files must conform to minimum file permission requirements. (Cat II impact)

Discussion

This check verifies that the key web server system configuration files are owned by the SA or Web Manager controlled account. These same files which control the configuration of the web server, and thus its behavior, must also be accessible by the account which runs the web service. If these files are altered by a malicious user, the web server would no longer be under the control of its managers and owners; properties in the web server configuration could be altered to compromise the entire server platform.

Check Content

Locate and examine the httpd.conf file. Look for the section: <ServerRoot>. This section will contain the path to the configuration and binary files. Note: This check also applies to any other directory where CGI scripts are located. Permissions on this directory files should be: Administrators: Full control System: Full Control WebAdmin: Full Control WebUser: Read, Execute Apache Service Account: Read, Execute Permissions for the /config directory should be as follows: (This is a sub directory to the main apache directory identified above) Administrators: Full control System: Read WebAdmin: Modify Apache Service Account: Read Permissions for the /bin directory should be as follows: (This is a sub directory to the main apache directory identified above) Administrators: Full control System: Read, Execute WebAdmin: Modify Apache Service Account: Read, Execute Permissions for the /logs directory should be as follows: (This is a sub directory to the main apache directory identified above) Administrators: Read System: Full Control WebAdmin: Read Apache Service Account: Modify Auditors: Full Control Permissions for the /htdocs directory (DocumentRoot) should be as follows: (This is a sub directory to the main apache directory identified above) Administrators: Full control System: Read WebAdmin: Modify Apache Service Account: Read If any of the above permissions are less restrictive, this is a finding. Note: There may be additional directories based the local implementation, and permissions should apply to directories of similar content. Ex. all web content directories should follow the permissions for /htdocs.

Fix Text

Set file permissions on the web server systems files to meet minimum file permissions requirements.
