CVE-2025-3285 in Arena
Summary
by MITRE • 04/08/2025
A local code execution vulnerability exists in the Rockwell Automation Arena® due to a threat actor being able 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.

The vulnerability identified as CVE-2025-3285 represents a critical local code execution flaw within Rockwell Automation Arena®, a widely used industrial automation software platform. This vulnerability stems from inadequate input validation mechanisms that fail to properly sanitize user-supplied data, creating a dangerous condition where malicious actors can manipulate the application's memory handling processes. The flaw specifically manifests as a buffer over-read condition that allows threat actors to access memory locations beyond the intended allocated buffers, potentially exposing sensitive system information and executing arbitrary code with the privileges of the affected user. The vulnerability's exploitation requires a specific user interaction pattern involving the opening of a malicious DOE file, which serves as the initial attack vector for privilege escalation and system compromise.
The technical nature of this vulnerability aligns with CWE-125, which describes out-of-bounds read conditions in software systems, and demonstrates how improper validation of user inputs can lead to memory corruption issues. The attack scenario requires a legitimate user to open a specially crafted DOE file, which indicates this vulnerability operates within the context of social engineering and user interaction-based attacks. This particular exploit path makes the vulnerability particularly dangerous in industrial environments where users may not be adequately trained to recognize malicious file attachments or where automated file handling processes might inadvertently execute malicious content. The buffer over-read condition creates a pathway for information disclosure that could reveal system memory contents, potentially exposing sensitive operational data, configuration information, or authentication credentials stored within the application's memory space.
The operational impact of CVE-2025-3285 extends beyond simple code execution to encompass significant threats to industrial control system security and operational integrity. In industrial automation environments, the ability to execute arbitrary code on a system running Arena® could lead to unauthorized modifications of control processes, disruption of manufacturing operations, or even physical damage to industrial equipment. The vulnerability's requirement for user interaction reduces its automatic exploitation potential but does not eliminate the risk, as industrial environments often face sophisticated social engineering campaigns targeting operational technology personnel. The information disclosure aspect of this vulnerability could expose critical operational data including process parameters, control logic, or system configurations that could be leveraged by threat actors to plan more sophisticated attacks against the industrial control infrastructure.
From a cybersecurity framework perspective, this vulnerability maps to several ATT&CK techniques including T1059 for command and scripting interpreter and T1068 for exploit for privilege escalation, while also representing a significant weakness in the software supply chain and user interaction security domains. Organizations operating Rockwell Automation Arena® systems should implement comprehensive security measures including user education programs, file validation procedures, and network segmentation to limit the potential impact of such vulnerabilities. The mitigation strategy should emphasize the importance of validating all user-supplied data, implementing proper input sanitization, and maintaining updated security controls that can detect and prevent the execution of malicious files. Additionally, regular security assessments of industrial automation systems should include specific evaluation of file handling processes and user interaction points that could be exploited by adversaries seeking to leverage similar buffer over-read vulnerabilities.
