Vulnerability discussion

An attacker can compromise a web server during the startup process. If logging is not initiated until all the Apache web server processes are started, key information may be missed and not available during a forensic investigation. To ensure all logable events are captured, the Apache web server must begin logging once the first Apache web server process is initiated.

Check content

In a command line, run "httpd -M | grep -i log_config_module". If the "log_config_module" is not enabled, this is a finding. Determine the location of the "HTTPD_ROOT" directory and the "httpd.conf" file: # httpd -V | egrep -i 'httpd_root|server_config_file' -D HTTPD_ROOT="/etc/httpd" -D SERVER_CONFIG_FILE="conf/httpd.conf" Search for the directive "LogFormat" in the "httpd.conf" file: # cat //httpd.conf | grep -i "LogFormat" If the "LogFormat" directive is missing or does not look like the following, this is a finding: LogFormat "%a %A %h %H %l %m %s %t %u %U \"%{Referer}i\

Fix text

Determine the location of the "HTTPD_ROOT" directory and the "httpd.conf" file: # httpd -V | egrep -i 'httpd_root|server_config_file' -D HTTPD_ROOT="/etc/httpd" -D SERVER_CONFIG_FILE="conf/httpd.conf" Uncomment the "log_config_module" module line. Configure the "LogFormat" in the "httpd.conf" file to look like the following: LogFormat "%a %A %h %H %l %m %s %t %u %U \"%{Referer}i\" " combined Restart Apache: apachectl restart

Pro Tips

Lavender hyperlinks in small type off to the right (of CSS class id, if you view the page source) point to globally unique URIs for each document and item. Copy the link location and paste anywhere you need to talk unambiguously about these things.

You can obtain data about documents and items in other formats. Simply provide an HTTP header Accept: text/turtle or Accept: application/rdf+xml.
