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

  - The ePO extension is affected by an unspecified denial
    of service vulnerability via a database lock or license
    corruption, which can be exploited by an authenticated,
    remote attacker. (CVE-2015-2757)

  - An information disclosure vulnerability exists in the
    ePO extension that allows an authenticated, remote
    attacker to obtain sensitive information or modify the
    database by using a specially crafted URL.
    (CVE-2015-2758)

  - Multiple cross-site request forgery vulnerabilities
    exist in the ePO extension that allow a remote attacker
    to hijack the authentication of users, resulting in
    disclosure of sensitive information or modification of
    the database. (CVE-2015-2759)

  - An unspecified cross-site scripting vulnerability exists
    in the ePO extension, which an authenticated, remote
    attacker can exploit to inject arbitrary script or HTML.
