Background
hapi is an open-source framework for building applications and services in Node.js. It provides a robust set of features for creating web servers, APIs, and other networked applications. However, versions 2.0.x and 2.1.x of hapi are vulnerable to a denial of service (DoS) attack due to a file descriptor leak. This vulnerability can be exploited to exhaust the server's file descriptors, leading to the termination of the node process. The severity of the attack depends on the process file descriptor limit.
