Malicious code inserted into the open-source library XZ Utils, a widely used package available in many popular Linux distributions, can potentially be used to facilitate remote code execution, based on a recent analysis from the security community. The XZ Utils supply chain vulnerability, listed as CVE-2024-3094, has been scored at the highest CVSS (Common Vulnerability Scoring System) level of 10.0.

What is XZ Utils?

XZ Utils is a command-line tool used for compressing and decompressing data in Linux and other Unix-like operating systems.

Vulnerability Details

Although the investigation is still ongoing, it appears that the malicious backdoor code is said to have been deliberately introduced into the open-source code by one of the project maintainers. The supply chain attack allows for a backdoor to be created through the SSH daemon authentication process on the vulnerable machine. The result of running the malicious code allows a remote attacker to execute arbitrary code on the machine.

The backdoor affects XZ Utils 5.6.0 and 5.6.1 releases, and only exists in a complete package download.

Current Analysis

We have completed our internal investigation and determined that the XZ Utils vulnerability is not
applicable to Neat products.
