Python Library Tornado 6.5.0 DoS

high Nessus Plugin ID 237199

Synopsis

A Python library installed on the remote host is affected by a DoS vulnerability.

Description

The detected version of the Tornado Python package, Tornado, is prior to 6.4.2.
It is therefore affected by a DoS vulnerability that happens When Tornado's multipart/form-data parser encounters certain errors, it logs a warning but continues trying to parse the remainder of the data. This allows remote attackers to generate an extremely high volume of logs, constituting a DoS attack. This DoS is compounded by the fact that the logging subsystem is synchronous.:

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 Tornado version 6.5.0 or later.
