Background
HuTool is an open-source Java library that provides a wide range of utility functions for developers. It is commonly used for tasks such as file manipulation, network communication, and data processing. The library is widely adopted in various Maven projects. However, versions up to 5.8.10 of HuTool are susceptible to a vulnerability that allows for uncontrolled resource consumption. This vulnerability resides in the 'cn.hutool.core.util.ZipUtil' class and can be exploited remotely. Attackers can leverage this vulnerability to exhaust system resources, potentially leading to denial of service or other malicious activities. The vulnerability has been publicly disclosed and is considered high severity with a CVSS score of 7.5.
Vulnerability Detail
