Official Description

An uninitialized pointer in Rockwell Automation Arena Simulation software could potentially allow a malicious user to insert unauthorized code to the software by leveraging the pointer after it is properly.

Technical Analysis

CVE-2024-21919 requires local access, meaning attackers must already have a foothold on the target system.

Exploitation does not require any privileges, though user interaction (Required) is needed, which slightly reduces the risk of mass automated attacks.

A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 7.8.
