These ports bind to an internal service that performs an HTTP 301 redirect to the HTTPS port (443/tcp) on the same interface IP address. After redirection, a web client will attempt to connect to the original destination IP address on 443/tcp and, if any such service is configured on the interface by the administrator (such as on the GlobalProtect portal or the device management interface), the client will connect successfully. In the absence of a configured service, any connection to 443/tcp will time out as expected. \n\nThis security advisory is rated as “informational” because there are no known vulnerabilities or immediate security risks posed by this issue; however, because unexpected open ports (28869/tcp and 28870/tcp) may appear in routine scans or audits, we advise you to review this issue and determine appropriate next steps for your environment.
