"The version of McAfee ePolicy Orchestrator (ePO) installed on the
remote Windows host is 4.x prior to 4.6.9 or 5.x prior to 5.1.2. It
is, therefore, affected by multiple vulnerabilities :

  - An XXE (XML External Entity) injection vulnerability
    exists in the Server Task Log due to an incorrectly
    configured XML parser accepting XML external entities
    from an untrusted source. A remote, authenticated
    attacker, by sending specially crafted XML data via the
    'conditionXML' parameter, can gain access to arbitrary
    files. (CVE-2015-0921)

  - An information disclosure vulnerability exists due to
    the use of a shared secret key to encrypt password
    information. A remote attacker with knowledge of the key
    can decrypt the administrator password. (CVE-2015-0922)");
