Assigner: openjs

Description
body-parser 2.2.0 is vulnerable to denial of service due to inefficient handling of URL-encoded bodies with very large numbers of parameters. An attacker can send payloads containing thousands of parameters within the default 100KB request size limit, causing elevated CPU and memory usage. This can lead to service slowdown or partial outages under sustained malicious traffic. This issue is addressed in version 2.2.1.

Executive Summary

The vulnerability in body-parser 2.2.0 is a denial of service issue caused by inefficient handling of URL-encoded bodies with very large numbers of parameters. An attacker can send requests containing thousands of parameters within the default 100KB request size limit, which causes elevated CPU and memory usage. This can slow down the service or cause partial outages if the malicious traffic is sustained.

Impact Analysis

This vulnerability can impact you by causing your service to slow down or partially go offline due to high CPU and memory usage triggered by malicious requests with many parameters. This can degrade the availability and performance of your application under attack.

Mitigation Strategies

Upgrade body-parser to version 2.2.1 or later, where this vulnerability is fixed. Additionally, consider implementing request size limits and parameter count limits to reduce the risk of denial of service from large URL-encoded payloads.
