This vulnerability allows remote attackers to disclose sensitive information on affected installations of MailEnable. Authentication is required to exploit this vulnerability.\n\nThe specific flaw exists within the implementation of the parseObjectResponse method. The issue results from the lack of proper restriction of XML External Entity (XXE) references. An attacker can leverage this vulnerability to disclose information in the context of the service account.
