Rockwell Automation Arena vulnerability analysis and mitigation

A local code execution vulnerability (CVE-2025-2287) was discovered in Rockwell Automation Arena® software, affecting versions 16.20.08 and prior. The vulnerability was disclosed on April 8, 2025, and stems from an uninitialized pointer issue. The flaw affects the Arena simulation software, which is primarily used in critical manufacturing sectors worldwide (CISA Advisory, NVD).

The vulnerability is caused by an uninitialized pointer and results from improper validation of user-supplied data. It has been assigned a CVSS v3.1 base score of 7.8 (High) with the vector string CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H, and a CVSS v4.0 base score of 8.5 with the vector string CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:P/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N. The vulnerability is classified under CWE-457 (Use of Uninitialized Variable) (Rockwell Advisory, CISA Advisory).

If successfully exploited, this vulnerability allows an attacker to disclose sensitive information and execute arbitrary code on the affected system. The impact is particularly significant as it affects critical manufacturing sectors worldwide (CISA Advisory, Rockwell Advisory).

Rockwell Automation has released version 16.20.09 to address this vulnerability. Users are recommended to upgrade to this version or later. For users unable to upgrade immediately, Rockwell Automation encourages the implementation of their suggested security best practices to minimize the risk of exploitation (CISA Advisory, Rockwell Advisory).
