IBM Cloud Pak System is affected by a remote code execution in Spring Framework (CVE-2022-22965 and CVE-2020-5421). IBM Cloud Pak System ships with AWS component that includes it but is not used by it. The fix removes Spring from the product. This security bulletin service applies to IBM Cloud Pak System, BM Cloud Pak System Software and BM Cloud Pak System Software Suite.
DESCRIPTION: Spring Framework could allow a remote attacker to execute arbitrary code on the system, caused by the improper handling of PropertyDescriptor objects used with data binding. By sending specially-crafted data to a Spring Java application, an attacker could exploit this vulnerability to execute arbitrary code on the system. Note: The exploit requires Spring Framework to be run on Tomcat as a WAR deployment with JDK 9 or higher using spring-webmvc or spring-webflux. Note: This vulnerability is also known as Spring4Shell or SpringShell.
