Background
Alluxio is an open-source data orchestration system that provides a unified interface for accessing various storage systems. It is commonly used in big data and machine learning applications to improve data access performance. Alluxio allows users to interact with data stored in different storage systems, such as Hadoop Distributed File System (HDFS) and Amazon S3, through a single API. This vulnerability affects Alluxio versions 2.9.3 and earlier.
Vulnerability Detail
The vulnerability in Alluxio allows an attacker to execute arbitrary code by exploiting a flaw in the lluxio.util.CommonUtils.getUnixGroups function. By providing a crafted script to the username parameter of this function, an attacker can trigger the execution of arbitrary code. This can lead to unauthorized access, data breaches, and potential compromise of the entire Alluxio system.
How To Fix
