NixOS vulnerability analysis and mitigation

Overview

A heap-based memory buffer overflow vulnerability (CVE-2024-21913) was discovered in Rockwell Automation Arena Simulation software versions 16.00.00 through 16.20.03. The vulnerability was disclosed on March 26, 2024, affecting the simulation software's memory handling capabilities (NIST NVD, CISA Advisory).

Technical details

The vulnerability is classified as a heap-based buffer overflow (CWE-122) with a CVSS v3.1 base score of 7.8 (High) and vector string AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H. Additionally, it has a CVSS v4.0 score of 8.4 with vector string CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N. The vulnerability allows a malicious user to insert unauthorized code into the software by overstepping memory boundaries, which triggers an access violation (CISA Advisory).

Impact

Successful exploitation of this vulnerability could allow an attacker to run harmful code on the system, affecting the confidentiality, integrity, and availability of the product. The vulnerability requires user interaction, specifically opening a malicious file shared by the threat actor (NIST NVD).

Mitigation and workarounds
