Descriptions

A remote
code execution security issue exists in the Rockwell Automation Arena®. A crafted DOE
file can force Arena Simulation to write beyond the boundaries of an allocated
object. Exploitation
requires user interaction, such as opening a malicious file within the software.
If exploited, a threat actor could execute arbitrary code on the target system.
The software must run under the context of the administrator in order to cause
worse case impact. This is reflected in the Rockwell CVSS score, as AT:P.

This vulnerability allows remote attackers to execute arbitrary code on affected installations of Rockwell Automation Arena Simulation. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.
The specific flaw exists within the parsing of DOE files. The issue results from the lack of proper validation of user-supplied data, which can result in a write past the end of an allocated object. An attacker can leverage this vulnerability to execute code in the context of the current process.
