MikroTik Winbox < 5.17 File Download DoS

Medium Nessus Plugin ID 59732

Synopsis

The remote host has an application installed that is affected by a denial of service vulnerability.

Description

According to its self-reported version number, the installation of MikroTik Winbox hosted on the remote web server is affected by a denial of service vulnerability. An unauthenticated, remote attacker may make multiple requests to download a large file, resulting in the service becoming unresponsive. Successful attacks can disconnect all Winbox clients, and make the service unresponsive for several minutes.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Upgrade to MikroTik RouterOS 5.17 or later, disable the Winbox service, or restrict the hosts that can access it.
