There are multiple vulnerabilities in Spring Framework (CVE-2022-22968, CVE-2022-22965, and CVE-2022-22950) as described in the vulnerability details section. Spring Framework v5.3.8 is used by Db2 Web Query for i for infrastructure support. IBM has addressed the vulnerabilities in Db2 Web Query for i by upgrading to Spring Framework v5.3.19.
DESCRIPTION: Spring Framework could provide weaker than expected security, caused by a data binding rules vulnerability in which the patterns for disallowedFields on a DataBinder are case sensitive. The case sensitivity allows that a field is insufficiently protected unless it is listed with both upper and lower case for the first character of the field. An attacker could exploit this vulnerability to launch further attacks on the system.
CVSS Base score: 3.7

CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:L/A:N)
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.
