Vulnerability discussion

Denial of Service is one threat against web servers. Many DoS attacks attempt to consume web server resources in such a way that no more resources are available to satisfy legitimate requests. Mitigation against these threats is to take steps to limit the number of resources that can be consumed in certain ways.tc Server provides the “connectionTimeout” attribute. This sets the number of milliseconds tc Server will wait, after accepting a connection, for the request URI line to be presented. This timeout will also be used when reading the request body (if any).

Check content

Navigate to and open /usr/lib/vmware-casa/casa-webapp/conf/server.xml. Navigate to each of the nodes. If the value of “connectionTimeout” is not set to “20000” or is missing, this is a finding.

Fix text

Navigate to and open /usr/lib/vmware-casa/casa-webapp/conf/server.xml. Navigate to each of the nodes. Configure each with the value 'connectionTimeout="20000"'.

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.
