Ruby RACK < 2.2.14 / 3.0.16 / 3.1.14 DoS vulnerability

high Nessus Plugin ID 236779

Language:

Synopsis

The remote host has an application installed that is affected by DoS vulnerability.

Description

The version of the RACK Ruby library installed on the remote host is prior to 2.2.14 / 3.0.16 / 3.1.14 . It is, therefore, affected by a DoS vulnerability where an attacker can trigger denial of service by sending specifically crafted HTTP requests, which can cause memory exhaustion or pin CPU resources, stalling or crashing the Rack server. This results in full service disruption until the affected worker is restarted.

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 RACK version 2.2.14 / 3.0.16 / 3.1.14 or later.
