Lifecycle Timeline
2DescriptionCVE.org
A security issue exists within Arena® Simulation due to a memory corruption vulnerability in the siman.exe (Siman) component. The vulnerability stems from improper validation of user-supplied data, which can result in an out-of-bounds write. An attacker could leverage this vulnerability to execute arbitrary code in the context of the current process by convincing a user to open a malicious file.
AnalysisAI
Arbitrary code execution in Rockwell Automation Arena Simulation is possible through an out-of-bounds write in the siman.exe (Siman) simulation-language component, which mishandles user-supplied data when parsing a model file. An attacker who convinces a user to open a crafted Arena file can run code in the context of that user's process. There is no public exploit identified at time of analysis and the CVE is not listed in CISA KEV, so risk is currently theoretical rather than actively exploited.
