Recommendations: For versions before E5771h-937TCPU-V200R001B328D62SP00C1133, update to a version after E5771h-937TCPU-V200R001B328D62SP00C1133 to resolve the issue. For versions before E5771h-937TCPU-V200R001B329D05SP00C1308, update to a version after E5771h-937TCPU-V200R001B329D05SP00C1308 to resolve the issue. As a temporary workaround, consider restricting access to the webserver process to minimize the risk of exploitation.
