CVE-2025-7032: CWE-121: Stack-based Buffer Overflow in Rockwell Automation Arena® Simulation
A memory abuse issue exists in the Rockwell Automation Arena® Simulation. A custom file can force Arena Simulation to read and write past the end of memory space. Successful use requires user action, such as opening a bad file or webpage. If used, a threat actor could execute code or disclose information.
AI Analysis
Technical Summary
CVE-2025-7032 is a high-severity stack-based buffer overflow vulnerability (CWE-121) found in Rockwell Automation's Arena® Simulation software, affecting versions 16.20.09 and prior. The vulnerability arises from improper handling of custom input files, which can cause the application to read and write beyond the allocated memory bounds on the stack. This memory corruption can lead to arbitrary code execution or information disclosure. Exploitation requires user interaction, such as opening a maliciously crafted file or visiting a webpage that triggers the vulnerable file processing. The CVSS 4.0 base score is 8.4, indicating a high risk, with an attack vector classified as local (AV:L), low attack complexity (AC:L), no privileges required (PR:N), but requiring user interaction (UI:A). The vulnerability impacts confidentiality, integrity, and availability with high impact, and no known exploits are currently reported in the wild. The lack of a patch link suggests that a fix may not yet be publicly available or is pending release. Given the nature of the vulnerability, threat actors could leverage it to execute arbitrary code within the context of the user running Arena Simulation, potentially leading to system compromise or leakage of sensitive simulation data.
Potential Impact
For European organizations, especially those in industrial automation, manufacturing, and engineering sectors that rely on Rockwell Automation's Arena Simulation for process modeling and simulation, this vulnerability poses a significant risk. Successful exploitation could allow attackers to execute arbitrary code, potentially leading to unauthorized control over simulation environments or exfiltration of proprietary simulation data. This could disrupt operational planning, lead to intellectual property theft, or serve as a foothold for further network intrusion. The requirement for user interaction limits mass exploitation but targeted spear-phishing campaigns or compromised internal resources could facilitate attacks. Given the critical role of simulation in process optimization and safety analysis, any compromise could have downstream effects on production efficiency and safety compliance. Additionally, the high confidentiality and integrity impact could affect organizations subject to strict data protection regulations such as GDPR, increasing legal and reputational risks.
Mitigation Recommendations
European organizations should implement the following specific mitigations: 1) Immediately restrict access to Arena Simulation software to trusted users and environments, minimizing exposure to untrusted files or web content. 2) Educate users on the risks of opening files from unknown or untrusted sources, emphasizing the need for caution with simulation input files. 3) Employ application whitelisting and sandboxing techniques to isolate Arena Simulation processes and limit the impact of potential exploitation. 4) Monitor network and endpoint logs for unusual activity related to Arena Simulation, such as unexpected file access or process behavior. 5) Coordinate with Rockwell Automation for timely updates and patches; if no patch is available, consider temporary disabling or restricting the use of affected versions until remediation is released. 6) Implement strict email filtering and web content filtering to reduce the risk of delivering malicious files or links that could trigger the vulnerability. 7) Conduct regular vulnerability assessments and penetration testing focusing on simulation environments to detect potential exploitation attempts.
