Background
The get-ip-range package is a Node.js module that provides functionality for working with IP ranges. It allows users to manipulate and extract information from IP ranges. This package is commonly used in Node.js applications that require IP range processing. However, versions prior to 4.0.0 are vulnerable to a denial of service (DoS) attack if untrusted input is provided as the range parameter. An attacker can exploit this vulnerability by sending a large range, such as 128.0.0.0/1, which can lead to resource exhaustion.
Vulnerability Detail
The vulnerability in get-ip-range arises from inadequate input validation. When an untrusted range is provided, the package fails to handle it properly, resulting in a DoS condition. An attacker can abuse this vulnerability to consume excessive resources, potentially leading to service disruption or unavailability. The severity of this vulnerability is rated as HIGH with a CVSS score of 7.5. It is crucial to update the get-ip-range dependency to version 4.0.0 or above to mitigate this vulnerability.
