Proper authentication is not required to exploit this vulnerability. The specific flaw exists due to a hidden manager-level account with a default password defined in the user configuration of the bundled Tomcat server.

By abusing this ability a remote attacker can execute arbitrary code under the context of the user running the Tomcat server. -- Vendor Response: IBM has issued an update to correct this vulnerability.
