high Nessus Plugin ID 136566

Language:

Synopsis

The remote Windows host is affected by a .NET Core SDK denial of service vulnerability.

Description

The Microsoft .NET Core SDK installation on the remote host is version 2.1.x < 2.1.514 or 2.1.611 or 2.1.806, or 3.1.x < 3.1.104 or 3.1.202. It is, therefore, affected by a denial of service vulnerability due to an unspecified flaw related to handling web requests. An unauthenticated, remote attacker could cause denial of service conditions by sending specially crafted web requests.

Solution

Refer to vendor documentation.
