"The remote McAfee ePO server has a vulnerable version of McAfee Data
Loss Protection Endpoint (DLPe) extension installed that is affected
by multiple vulnerabilities :

  - An unspecified SQL injection vulnerability exists due to
    improper sanitization of user-supplied input. This
    allows an authenticated, remote attacker to inject or
    manipulate SQL queries, resulting in the disclosure of
    sensitive information. (CVE-2015-1616)

  - An unspecified cross-site scripting vulnerability exists
    due to improper validation of user-supplied input. This
    allows an authenticated, remote attacker to execute
    arbitrary script code in a user's browser session.
    (CVE-2015-1617)

  - An information disclosure vulnerability exists due to
    access checks not being properly enforced. A remote,
    authenticated attacker can gain access to password
    information via a specially crafted URL.
    (CVE-2015-1618)");
