Remediation

Source guidance available

Review the recorded instructions. Guidance may be a workaround rather than a fixed version.

What this means

The third-party RMM+ extension for ConnectWise ScreenConnect uses a static API secret by default. The value can be changed by an administrator; however, environments retaining the default value may allow unauthorized access to extension API functionality, including the ability to send commands to managed agents. This issue is specific to the third-party extension and does not affect the ScreenConnect server or client.
