## Overview
[org.apache.cxf:cxf-core](https://github.com/apache/cxf) is a an open source
services framework. CXF helps you build and develop services using frontend
programming APIs, like JAX-WS and JAX-RS.
Affected versions of this package are vulnerable to Denial of Service (DoS).
Apache CXF does not restrict the number of message attachments present in a
given message. This leaves open the possibility of a denial of service type
attack, where a malicious user crafts a message containing a very large number
of message attachments.
## Details
Denial of Service (DoS) describes a family of attacks, all aimed at making a
system inaccessible to its intended and legitimate users.
Unlike other vulnerabilities, DoS attacks usually do not aim at breaching
security. Rather, they are focused on making websites and services unavailable
to genuine users resulting in downtime.
One popular Denial of Service vulnerability is DDoS (a Distributed Denial of
Service), an attack that attempts to clog network pipes to the system by
generating a large volume of traffic from many machines.
When it comes to open source libraries, DoS vulnerabilities allow attackers to
trigger such a crash or crippling of the service by using a flaw either in the
application code or from the use of open source libraries.
Two common types of DoS vulnerabilities:
* High CPU/Memory Consumption- An attacker sending crafted requests that could
cause the system to take a disproportionate amount of time to process. For
example,
[commons-fileupload:commons-fileupload](SNYK-JAVA-COMMONSFILEUPLOAD-30082).
* Crash - An attacker sending crafted requests that could cause the system to
crash. For Example, [npm `ws` package](npm:ws:20171108)
## Remediation
Upgrade `org.apache.cxf:cxf-core` to version 3.3.4, 3.2.11 or higher.
