OVERVIEW

        Multiple vulnerabilities have been identified in :
         o Oracle Life Sciences Empirica Signal, versions 9.1.0.53,
           9.2.0.53
        [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. Neither of these
        vulnerabilities
        may be remotely exploitable without authentication, i.e., neither
        may
        be exploited over a network without requiring user credentials."
        [1]

        "CVE-2023-5072
         6.5 AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H
        Supported versions that are affected are 9.1.0.53 and 9.2.0.53.
        Easily exploitable vulnerability allows low privileged attacker
        with
        network access via HTTP to compromise Oracle Life Sciences Empirica
        Signal. Successful attacks of this vulnerability can result in
        unauthorized ability to cause a hang or frequently repeatable crash
        (complete DOS) of Oracle Life Sciences Empirica Signal.
         Affects:
         o Oracle Life Sciences Empirica Signal 9.1.0.53, 9.2.0.53

        CVE-2023-42503
         5.0 AV:L/AC:L/PR:L/UI:R/S:U/C:N/I:N/A:H
        Supported versions that are affected are 9.1.0.53 and 9.2.0.53.
        Easily exploitable vulnerability allows low privileged attacker
        with
        logon to the infrastructure where Oracle Life Sciences Empirica
        Signal executes to compromise Oracle Life Sciences Empirica Signal.
        Successful attacks require human interaction from a person other
        than
        the attacker. Successful attacks of this vulnerability can result
        in
        unauthorized ability to cause a hang or frequently repeatable crash
        (complete DOS) of Oracle Life Sciences Empirica Signal.
         Affects:
         o Oracle Life Sciences Empirica Signal 9.1.0.53, 9.2.0.53" [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]
