Technical details

An out-of-bounds write vulnerability (CWE-787) exists in the linker.exe (Siman) component of Rockwell Automation Arena Simulation. The issue is caused by improper validation of user-supplied data when processing files. An attacker can exploit this by convincing a local user to open a malicious file, leading to memory corruption. Successful exploitation allows for arbitrary code execution within the context of the current process. The vulnerability is addressed in version V17.00.01.
