CVE-2025-2829
Remediation/Mitigation Strategy for CVE-2025-2829 in Rockwell Automation Arena®
Vulnerability Description:
A local code execution vulnerability exists in Rockwell Automation Arena® due to a buffer overflow. A threat actor can write outside of the allocated memory buffer because of improper validation of user-supplied data. This flaw can lead to information disclosure and arbitrary code execution on the system. The vulnerability is triggered when a legitimate user opens a malicious DOE file.
Severity:
CVSS Score: 8.5 (High)
Known Exploit:
Exploitation requires a legitimate user to open a specifically crafted, malicious DOE file. The attack vector is local, requiring the attacker to convince a user to interact with the malicious file. Successful exploitation allows the attacker to execute arbitrary code with the privileges of the user running the application.
Remediation/Mitigation Strategy:
Apply Patch/Update: The primary mitigation is to apply the official patch or update released by Rockwell Automation that addresses CVE-2025-2829. Monitor Rockwell Automation’s security advisories for the patch availability and installation instructions.
User Awareness Training: Conduct user awareness training to educate users about the risks of opening files from untrusted sources, including DOE files. Emphasize the importance of verifying the authenticity and integrity of files before opening them.
File Origin Verification: Implement procedures to verify the origin and integrity of DOE files before opening them. If possible, establish a trusted source or repository for DOE files.
Principle of Least Privilege: Ensure that users of Arena® have the minimum necessary privileges to perform their tasks. Restricting user privileges can limit the potential impact of a successful exploit.
Network Segmentation (if applicable): If Arena® is used in a networked environment, consider segmenting the network to limit the lateral movement of an attacker in case of successful exploitation.
Monitoring and Detection: Implement security monitoring and intrusion detection systems to detect suspicious activity that may indicate an attempted or successful exploitation of CVE-2025-2829. Monitor for unexpected process creation, file modifications, and network connections originating from the Arena® application.
Workaround (If patch unavailable immediately): Until a patch can be applied, consider implementing a temporary workaround, such as restricting the types and sizes of DOE files that can be opened or using a sandbox environment to open potentially malicious files. Note that workaround may reduce functionality.
Regular Security Audits: Conduct regular security audits and vulnerability assessments of systems running Arena® to identify and address any other potential vulnerabilities.
