OVERVIEW

        Multiple vulnerabilities have been identified in :
         o Oracle Healthcare Foundation, versions 7.1.1, 7.2.2
         o Oracle Healthcare Translational Research, versions 3.1.0,
           3.2.1, 3.3.1 [1]


IMPACT

        The vendor has provided the following information regarding the
        vulnerabilities:
        
        "This Critical Patch Update contains 2 new security patches for
        Oracle Health Sciences Applications. Both of these vulnerabilities
        may be remotely exploitable without authentication, i.e., may be
        exploited over a network without requiring user credentials." [1]
        
        "CVE-2019-11358
          6.1 AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N
        Easily exploitable vulnerability allows unauthenticated attacker with
        network access via HTTP to compromise Oracle Healthcare Foundation.
        Successful attacks require human interaction from a person other than
        the attacker and while the vulnerability is in Oracle Healthcare
        Foundation, attacks may significantly impact additional products.
        Successful attacks of this vulnerability can result in unauthorized
        update, insert or delete access to some of Oracle Healthcare
        Foundation accessible data as well as unauthorized read access to a
        subset of Oracle Healthcare Foundation accessible data.
         Affects:
         o Oracle Healthcare Foundation 7.1.1, 7.2.2
         o Oracle Healthcare Translational Research 3.1.0, 3.2.1, 3.3.1" [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]
