A local code execution vulnerability exists in the Rockwell Automation Arena® due to a threat actor being able to write outside of the allocated memory buffer. The flaw is a result of improper validation of user-supplied data. If exploited a threat actor can disclose information and execute arbitrary code on the system. To exploit the vulnerability a legitimate user must open a malicious DOE file.
