Details

The ‘package.access’ entry in the ‘catalina.properties’ file implements access control at the package level. When properly configured, a Security Exception will be reported if an errant or malicious web app attempts to access the listed internal classes directly or if a new class is defined under the protected packages.

The Security Token Service comes preconfigured with the appropriate packages defined in ‘package.access’, and this configuration must be maintained.

Solution

Navigate to and open /usr/lib/vmware-sso/vmware-sts/conf/catalina.properties.

Ensure that the ‘package.access’ line is configured as follows:

package.access=sun.,org.apache.catalina.,org.apache.coyote.,org.apache.tomcat.,org.apache.jasper.
