Fix Recommendation

Navigate to and open:

/usr/lib/vmware-sso/vmware-sts/conf/web.xml

Navigate to the /<web-apps>/<servlet>/<servlet-class>org.apache.catalina.servlets.DefaultServlet</servlet-class>/ node and remove the following node:

<init-param>
<param-name>readonly</param-name>
<param-value>false</param-value>
</init-param>

Restart the service with the following command:

# vmon-cli --restart sts

Check Contents

At the command prompt, run the following command:

# xmllint --xpath "//*[contains(text(), 'DefaultServlet')]/parent::*" /usr/lib/vmware-sso/vmware-sts/conf/web.xml

Example output:

<servlet>
<description>File servlet</description>
<servlet-name>FileServlet</servlet-name>
<servlet-class>org.apache.catalina.servlets.DefaultServlet</servlet-class>
</servlet>

If the "readOnly" param-value for the "DefaultServlet" servlet class is set to "false", this is a finding.

If the "readOnly" param-value does not exist, this is not a finding.
