Rapid7 Insight Agent is a software component used to monitor and collect security data from corporate endpoints.

Technical details

Rapid7 Insight Agent for Windows (versions prior to 4.1.0.2) incorrectly assigns permissions to installer certificate files located in the 'bootstrap/common/ssl' directory. Specifically, the 'client.key' file and other certificates are assigned read and execute permissions for standard users (CWE-732). A locally authenticated attacker with low privileges can access these files to extract agent identity material. This could be leveraged to impersonate the agent or interfere with its communication with the Insight platform. The issue is resolved in Insight Agent version 4.1.0.2.
