What is CVE-2018-25125?

The Netis ADSL Router DL4322D is impacted by a buffer overflow vulnerability in its embedded FTP service.

This action leads to a crash or unresponsiveness of the FTP service and, consequently, the router itself, resulting in loss of availability for the device and any users dependent on it. Timely patching and awareness of this vulnerability can help mitigate potential disruptions.
