Vulnerability discussion

A web server can limit the ability of the web server being used in a DoS attack through several methods. The methods employed will depend upon the hosted applications and their resource needs for proper operation. An example setting that could be used to limit the ability of the web server being used in a DoS attack is bandwidth throttling.

Check content

1. Open $DOMAIN_HOME/config/fmwconfig/components/OHS//httpd.conf and every .conf file (e.g., ssl.conf) included in it with an editor. 2. Search for the "LimitInternalRecursion" directive at the server, virtual host, and directory configuration scopes. 3. If the "LimitInternalRecursion" directive is omitted or is set greater than 55, this is a finding.

Fix text

1. Open $DOMAIN_HOME/config/fmwconfig/components/OHS//httpd.conf and every .conf file (e.g., ssl.conf) included in it with an editor. 2. Search for the "LimitInternalRecursion" directive at the server and virtual host configuration scopes. 3. Set the "LimitInternalRecursion" directive to "55", add the directive if it does not exist.

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.
