Uncontrolled Resource Consumption

CVE-2024-47535

High
8.3/10

Summary

Netty is an asynchronous event-driven network application framework for rapidly developing maintainable high-performance protocol servers & clients. An unsafe reading of the environment file could potentially cause a denial of service in Netty. When loaded on a Windows application, Netty attempts to load a file that does not exist. If an attacker creates such a large file, the Netty application crashes. This vulnerability affects Netty versions through 4.1.114.Final, 4.2.0.Beta1, 4.2.0.Alpha1 through 4.2.0.Alpha5, 5.0.0.Alpha1 through the 5.0.0.Alpha5.

CWE-400 - Uncontrolled resource consumption

An uncontrolled resource allocation attack (also known as resource exhaustion attack) triggers unauthorized overconsumption of the limited resources in an application, such as memory, file system storage, database connection pool entries, and CPU. This may lead to denial of service for valid users and degradation of the application's functionality as well as that of the host operating system.
