OVERVIEW

        A vulnerability has been identified in :
         o JD Edwards EnterpriseOne Tools, version 4.0.1.0 [1]


IMPACT

        The vendor has provided the following information regarding the
        vulnerability:
        
        "This Critical Patch Update contains 1 new security patch for Oracle
        JD Edwards. This vulnerability is remotely exploitable without
        authentication, i.e., may be exploited over a network without
        requiring user credentials." [1]
        
        "CVE-2017-5645
          9.8 AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
        Easily exploitable vulnerability allows unauthenticated attacker with
        network access via HTTP to compromise JD Edwards EnterpriseOne Tools.
        Successful attacks of this vulnerability can result in takeover of JD
        Edwards EnterpriseOne Tools.
         Affects:
         o JD Edwards EnterpriseOne Tools 4.0.1.0" [2]


MITIGATION

        Oracle states:
        
        "Due to the threat posed by a successful attack, Oracle strongly
        recommends that customers apply CPU fixes as soon as possible. Until
        you apply the CPU fixes, it may be possible to reduce the risk of
        successful attack by blocking network protocols required by an
        attack. For attacks that require certain privileges or access to
        certain packages, removing the privileges or the ability to access
        the packages from users that do not need the privileges may help
        reduce the risk of successful attack. Both approaches may break
        application functionality, so Oracle strongly recommends that
        customers test changes on non-production systems. Neither approach
        should be considered a long-term solution as neither corrects the
        underlying problem." [1]
