Background
org.apache.tomcat.embed:tomcat-embed-core is a package in the Maven ecosystem that provides embedded Tomcat functionality. It allows developers to run Tomcat within their applications, enabling them to deploy web applications without the need for a separate Tomcat installation. This package is widely used in Java web development.
Vulnerability Detail
This vulnerability, identified as CVE-2018-8037, is of moderate severity. It affects versions 9.0.0.M9 to 9.0.9 and 8.5.5 to 8.5.31 of org.apache.tomcat.embed:tomcat-embed-core. The vulnerability arises from a race condition that occurs when an async request is completed by the application at the same time as the container triggers the async timeout. This race condition can result in a user seeing a response intended for a different user. Additionally, the NIO and NIO2 connectors in the package do not correctly track the closure of the connection when an async request is completed by the application and timed out by the container simultaneously, leading to the same issue of users seeing responses intended for other users. The Common Weakness Enumeration (CWE) ID associated with this vulnerability is CWE-362.
