On Windows endpoints, the SecureConnector agent is vulnerable to privilege escalation whereby an authenticated unprivileged user can obtain administrator privileges on the endpoint by causing the SecureConnector agent to execute arbitrary code.
On Windows endpoints, the SecureConnector agent must run under the local SYSTEM account or another administrator account in order to enable full functionality of the agent. The typical configuration is for the agent to run as a Windows service under the local SYSTEM account. The SecureConnector agent runs various plugin scripts and executables on the endpoint in order to gather and report information about the host to the CounterACT management appliance. The SecureConnector agent downloads these scripts and executables as needed from the CounterACT management appliance and runs them on the endpoint.
CWE-378: Creation of Temporary File with Insecure Permissions - CVE-2016-9485
