the January 2021 CPU advisory.

  - Vulnerability in the Siebel Core - Server Framework product of Oracle Siebel CRM (component: Search).
    Supported versions that are affected are 20.12 and prior. Easily exploitable vulnerability allows low
    privileged attacker with network access via HTTP to compromise Siebel Core - Server Framework. Successful
    attacks require human interaction from a person other than the attacker and while the vulnerability is in
    Siebel Core - Server Framework, attacks may significantly impact additional products. Successful attacks
    of this vulnerability can result in unauthorized access to critical data or complete access to all Siebel
    Core - Server Framework accessible data as well as unauthorized update, insert or delete access to some of
    Siebel Core - Server Framework accessible data. (CVE-2021-2039)

  - Vulnerability in the Siebel UI Framework product of Oracle Siebel CRM (component: EAI (Apache Tomcat)).
    Supported versions that are affected are 20.12 and prior. Difficult to exploit vulnerability allows low

  - Vulnerability in the Siebel Mobile App product of Oracle Siebel CRM (component: Open UI (jQuery)).
    Supported versions that are affected are 20.12 and prior. Easily exploitable vulnerability allows 
    unauthenticated attacker with network access via HTTP to compromise Siebel Mobile App. Successful
    attacks require human interaction from a person other than the attacker and while the vulnerability is in
    Siebel Mobile App, attacks may significantly impact additional products. Successful attacks of this
    vulnerability can result in unauthorized update, insert or delete access to some of Siebel Mobile App 
    accessible data as well as unauthorized read access to a subset of Siebel Mobile App accessible data.
    (CVE-2020-11022)

  - Vulnerability in the Siebel Core - Server BizLogic Script product of Oracle Siebel CRM (component:
