VCST-70-000025 - The Security Token Service must not enable support for TRACE requests.

Information

'TRACE' is a technique for a user to request internal information about Tomcat. This is useful during product development but should not be enabled in production. Allowing an attacker to conduct a TRACE operation against the Security Token Service will expose information that would be useful to perform a more targeted attack.

The Security Token Service provides the 'allowTrace' parameter as means to disable responding to TRACE requests.

Solution

Navigate to and open:

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

Locate and remove the 'allowTrace='true'' setting.

Restart the service with the following command:

# vmon-cli --restart sts
