3. TECHNICAL DETAILS
3.1 AFFECTED PRODUCTS
The following Rockwell Automation products are affected:
- Arena: Versions 16.20.09 and prior
3.2 VULNERABILITY OVERVIEW
3.2.1 OUT-OF-BOUNDS READ CWE-125
A local code execution vulnerability exists in Rockwell Automation Arena due to a threat actor's ability to read 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.
CVE-2025-7025 has been assigned to this vulnerability. A CVSS v3.1 base score of 7.8 has been calculated; the CVSS vector string is (AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H).
A CVSS v4 score has also been calculated for CVE-2025-7025. A base score of 8.4 has been calculated; the CVSS vector string is (AV:L/AC:L/AT:N/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N).
3.2.2 STACK-BASED BUFFER OVERFLOW CWE-121
A local code execution vulnerability exists in Rockwell Automation Arena due to a stack-based memory buffer overflow. The flaw is a result of improper validation of user-supplied data. If exploited, a threat actor can execute arbitrary code on the system. To exploit the vulnerability a legitimate user must open a malicious DOE file.
CVE-2025-7032 has been assigned to this vulnerability. A CVSS v3.1 base score of 7.8 has been calculated; the CVSS vector string is (AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H).
A CVSS v4 score has also been calculated for CVE-2025-7032. A base score of 8.4 has been calculated; the CVSS vector string is (AV:L/AC:L/AT:N/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N).
3.2.3 HEAP-BASED BUFFER OVERFLOW CWE-122
A local code execution vulnerability exists in Rockwell Automation Arena due to a heap-based buffer overflow. The flaw is a result of improper validation of user-supplied data. If exploited, a threat actor can execute arbitrary code on the system. To exploit the vulnerability a legitimate user must open a malicious DOE file.
CVE-2025-7033 has been assigned to this vulnerability. A CVSS v3.1 base score of 7.8 has been calculated; the CVSS vector string is (AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H).
A CVSS v4 score has also been calculated for CVE-2025-7033. A base score of 8.4 has been calculated; the CVSS vector string is (AV:L/AC:L/AT:N/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N).

4. MITIGATIONS
Rockwell Automation recommends users updating to arena Version 16.20.10 or later.
For more information about these issues, reference the Rockwell Automation security advisory.
CISA recommends users take defensive measures to minimize the risk of exploitation of these vulnerabilities, such as:
- Minimize network exposure for all control system devices and/or systems, ensuring they are not accessible from the Internet.
- Locate control system networks and remote devices behind firewalls and isolating them from business networks.
- When remote access is required, use more secure methods, such as Virtual Private Networks (VPNs), recognizing VPNs may have vulnerabilities and should be updated to the most current version available. Also recognize VPN is only as secure as the connected devices.
CISA reminds organizations to perform proper impact analysis and risk assessment prior to deploying defensive measures.
CISA also provides a section for control systems security recommended practices on the ICS webpage on cisa.gov/ics. Several CISA products detailing cyber defense best practices are available for reading and download, including Improving Industrial Control Systems Cybersecurity with Defense-in-Depth Strategies.
CISA encourages organizations to implement recommended cybersecurity strategies for proactive defense of ICS assets.
Additional mitigation guidance and recommended practices are publicly available on the ICS webpage at cisa.gov/ics in the technical information paper, ICS-TIP-12-146-01B--Targeted Cyber Intrusion Detection and Mitigation Strategies.
Organizations observing suspected malicious activity should follow established internal procedures and report findings to CISA for tracking and correlation against other incidents.
No known public exploitation specifically targeting these vulnerabilities has been reported to CISA at this time. These vulnerabilities are not exploitable remotely.
