DescriptionCVE.org

A remote code execution security issue exists in the affected products when parsing DOE files that could allow a remote attacker to write past the end of an allocated object and execute code within the context of the current process. To exploit this vulnerability, a legitimate user must visit a malicious page or open a malicious file.

AnalysisAI

Remote code execution in Rockwell Automation Arena's DOE file parser allows a network-reachable attacker to write beyond the boundary of an allocated object and execute arbitrary code within the context of the running Arena process. Affected users must be socially engineered into opening a maliciously crafted Design of Experiments (DOE) file or visiting a page that triggers the parse. …

Vulnerability AssessmentAI

Exploitation Exploitation requires that a legitimate Arena user actively open a maliciously crafted DOE (Design of Experiments) file, or visit a web page that initiates such parsing - the CVSS UI:A metric confirms active user interaction is mandatory. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The CVSS 4.0 vector (AV:N/AC:H/AT:P/PR:N/UI:A) assigns high attack complexity and a specific attack requirement (AT:P), yielding a 7.5 score rather than a critical rating. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario Full exploit scenario with step-by-step reproduction available after sign-in.
Remediation Consult the Rockwell Automation security advisory SD1713 at https://www.rockwellautomation.com/en-us/trust-center/security-advisories/advisory.SD1713.html for the authoritative fixed version; no specific patch version was extractable from the available data, so it cannot be independently confirmed here. … Detailed patch versions, workarounds, and compensating controls in full report.

Recommended ActionAI

Within 24 hours, identify all Rockwell Automation Arena installations across the organization and notify users to avoid opening DOE files from untrusted sources; restrict .DOE file sharing and disable file preview features where available. …
