CVE-2025-2288: 
NixOS vulnerability analysis and mitigation

A local code execution vulnerability (CVE-2025-2288) was discovered in Rockwell Automation Arena® software versions 16.20.08 and prior. The vulnerability was disclosed on April 8, 2025, and affects the Arena simulation software. The flaw allows a threat actor to write outside of the allocated memory buffer due to improper validation of user-supplied data (CISA Advisory, Rockwell Advisory).

The vulnerability is classified as an Out-of-bounds Write (CWE-787) vulnerability. It has received a CVSS v4.0 base score of 8.5 HIGH 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. Additionally, it has a CVSS v3.1 base score of 7.8 with the vector string CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H. The vulnerability requires local access and user interaction to be exploited (CISA Advisory, NVD).

If successfully exploited, this vulnerability can allow an attacker to disclose information and execute arbitrary code on the affected system. The exploitation requires a legitimate user to open a malicious DOE file (CISA Advisory, Rockwell Advisory).

Rockwell Automation recommends users upgrade to Arena version 16.20.09 or later to address this vulnerability. Users are also encouraged to implement suggested security best practices to minimize the risk of exploitation (CISA Advisory, Rockwell Advisory).
