OVERVIEW

        Multiple vulnerabilities have been identified in :
         o Siebel Applications, versions 19.10 and prior
        [1]


IMPACT

        The vendor has provided the following information regarding the
        vulnerabilities:
        
        "This Critical Patch Update contains 5 new security patches for
        Oracle Siebel CRM. All of these vulnerabilities may be remotely
        exploitable without authentication, i.e., may be exploited over a
        network without requiring user credentials." [1]
        
        CVE-2019-14379
          9.8 AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
        Supported versions that are affected are 19.8 and prior. Easily
        exploitable vulnerability allows unauthenticated attacker with
        network access via HTTP to compromise Siebel Engineering - Installer
        and Deployment. Successful attacks of this vulnerability can result
        in takeover of Siebel Engineering - Installer and Deployment.
         Affects:
         o Siebel Engineering - Installer & Deployment 19.8 and prior
         o Siebel UI Framework 19.10 and prior
        
        CVE-2020-2564
          5.3 AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N
        Supported versions that are affected are 19.10 and prior. Easily
        exploitable vulnerability allows unauthenticated attacker with
        network access via HTTP to compromise Siebel UI Framework. Successful
        attacks of this vulnerability can result in unauthorized read access
        to a subset of Siebel UI Framework accessible data.
         Affects:
         o Siebel UI Framework 19.10 and prior
        
        CVE-2020-2559
          5.3 AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N
        Supported versions that are affected are 19.7 and prior. Easily
        exploitable vulnerability allows unauthenticated attacker with
        network access via HTTP to compromise Siebel UI Framework. Successful
        attacks of this vulnerability can result in unauthorized read access
        to a subset of Siebel UI Framework accessible data.
         Affects:
         o Siebel UI Framework 19.7 and prior
        
        CVE-2020-2560
          4.7 AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:N/A:N
        Supported versions that are affected are 19.10 and prior. Easily
        exploitable vulnerability allows unauthenticated attacker with
        network access via HTTP to compromise Siebel UI Framework. Successful
        attacks require human interaction from a person other than the
        attacker and while the vulnerability is in Siebel UI Framework,
        attacks may significantly impact additional products. Successful
        attacks of this vulnerability can result in unauthorized read access
        to a subset of Siebel UI Framework accessible data.
         Affects:
         o Siebel UI Framework 19.10 and prior


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]
