Vulnerability discussion

DoS is a condition when a resource is not available for legitimate users. When this occurs, the organization either cannot accomplish its mission or must operate at degraded capacity. To reduce the possibility or effect of a DoS, the application server must employ defined security safeguards. These safeguards will be determined by the placement of the application server and the type of applications being hosted within the application server framework.One way to cause a DoS for ColdFusion is to exhaust resources by using services that are not being monitored because of their nonuse by hosted applications. One of these services is Web Services. Web Services are services that allow an application to publish SOAP web services and when being used, the number of simultaneous requests should be tuned using load testing to find the optimal value for the setting. When not in use, this setting must be set to 1.

Check content

Determine if web services are being published for the hosted applications. This may be determined by interviewing the administrator or by reviewing hosted applications code, hosted application design documentation, published web services design documentation or ColdFusion baseline documentation. If Web Services are being published for hosted applications, this find is not applicable. Within the Administrator Console, navigate to the "Request Tuning" page under the "Server Settings" menu. If Web Services are not being published for hosted applications and the "Maximum number of simultaneous Web Service requests" is not set to 1, this is a finding.

Fix text

If Web Services are being published for hosted applications, this find is not applicable. Navigate to the "Request Tuning" page under the "Server Settings" menu. Set "Maximum number of simultaneous Web Service requests" to 1 and select the "Submit Changes" button.

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.
