OVERVIEW

        Multiple vulnerabilities have been identified in :
         o Oracle GoldenGate, version 19c
        [1]


IMPACT

        The vendor has provided the following information regarding the
        vulnerabilities:
        
        "This Critical Patch Update contains 2 new security patches plus
        additional third party patches noted below for Oracle GoldenGate. 1
        of these vulnerabilities may be remotely exploitable without
        authentication, i.e., may be exploited over a network without
        requiring user credentials." [1]
        
        "CVE-2020-35169
         9.8 AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
        The supported version that is affected is 19c. Easily exploitable
        vulnerability allows unauthenticated attacker with network access via
        HTTPS to compromise Oracle GoldenGate. Successful attacks of this
        vulnerability can result in takeover of Oracle GoldenGate.
         Affects:
         o Oracle GoldenGate 19c
        
        CVE-2018-18893
         4.3 AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N
        The supported version that is affected is 19c. Easily exploitable
        vulnerability allows low privileged attacker with network access via
        HTTP to compromise Oracle Goldengate. Successful attacks of this
        vulnerability can result in unauthorized read access to a subset of
        Oracle Goldengate accessible data.
         Affects:
         o Oracle Goldengate 19c" [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]
