If customers choose not to apply the remediation provided above, they should immediately apply the following mitigations to reduce the risk of exploit: • Do not enable remote access to PCSS Web UI. In the Windows Firewall incoming requests on TCP port 6547 (used by PCSS) are not allowed by default. • Harden the PowerChute Serial Shutdown Agent firewall rule by listing remote computers and/or users for which you want to allow/block remote connections on TCP port 6547. • Specific instructions for these mitigations can be found in the Security Handbook.
