Description Preview

The Rockwell Automation Thinmanager Thinserver contains an integer overflow vulnerability (CWE-190) that can lead to a denial of service condition. When processing incoming synchronization protocol messages, improper input validation allows malicious users to send specially crafted messages that trigger a read access violation, causing the Thinserver process to terminate unexpectedly.

Overview

This vulnerability affects the Rockwell Automation Thinmanager Thinserver component. The issue stems from improper validation of input data, specifically when processing synchronization protocol messages. The integer overflow condition occurs during message processing, resulting in a read access violation that terminates the Thinserver process. An attacker with the ability to send network messages to the affected system could exploit this vulnerability to cause a denial of service, disrupting the availability of the Thinmanager services. This type of vulnerability is particularly concerning in industrial control system environments where system availability is critical.

Remediation

Users should apply the latest security updates provided by Rockwell Automation for the affected Thinmanager products. Detailed remediation instructions are available in the Rockwell Automation Knowledge Base article referenced below. Additionally, organizations should implement network segmentation to limit access to the Thinmanager system, ensuring only authorized users and devices can communicate with it. Implement proper network monitoring to detect unusual traffic patterns or potential exploit attempts targeting the Thinserver component.
