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. The alluxio-core-common package is a fundamental component of Alluxio that includes common utilities and functionalities.
Vulnerability Detail
The vulnerability identified as CVE-2022-23848 involves a command injection issue in Alluxio before version 2.7.3. Specifically, the logserver component of Alluxio fails to properly validate the input stream, allowing an attacker to inject arbitrary commands. It is important to note that this vulnerability is distinct from the well-known Log4j vulnerability (CVE-2021-44228). The impact of this vulnerability can be severe, as it enables an attacker to execute arbitrary commands with the privileges of the user running the affected Alluxio instance. This could lead to unauthorized access, data manipulation, or even complete compromise of the system.
