Core Tomcat implementation

Dependency Hierarchy:

• spring-boot-starter-tomcat-1.2.3.RELEASE.jar (Root Library)

Found in HEAD commit: 02e23e894c65d5a9ac94fe97a3b06758376ae333

Vulnerability Details

The setGlobalContext method in org/apache/naming/factory/ResourceLinkFactory.java in Apache Tomcat 7.x before 7.0.68, 8.x before 8.0.31, and 9.x before 9.0.0.M3 does not consider whether ResourceLinkFactory.setGlobalContext callers are authorized, which allows remote authenticated users to bypass intended SecurityManager restrictions and read or write to arbitrary application data, or cause a denial of service (application disruption), via a web application that sets a crafted global context.
