Widget Factory.

Summary

A DoS vulnerability has been disclosed in the version of Apache Commons 
FileUpload JAR bundled with Web Experience Factory (WEF) and Lotus Widget 
Factory (LWF). This vulnerability also applies to WebSphere Dashboard 
Framework (WDF) which is an extension of WEF.

Vulnerability Details

A DoS vulnerability has been disclosed in the version of Apache Commons 
FileUpload JAR bundled with Web Experience Factory (WEF) and Lotus Widget 
Factory (LWF). This vulnerability also applies to WebSphere Dashboard 
Framework (WDF) which is an extension of WEF.

The file upload capability in WEF and LWF is disabled by default, therefore 
only those customers that use file upload are potentially vulnerable.

Although WEF and LWF ship a copy of Commons FileUpload most customers will not
use the bundled version in production. When deployed on Portal (the vast 
majority of production deployments) the vulnerable copy of Commons FileUpload
is omitted from the WAR and the copy of Commons FileUpload provided by Portal
is used instead. Therefore the majority of customers will need to wait for 
Portal to ship their patches for this vulnerability.

See Security Bulletin: Fixes available for vulnerability in Apache Commons 
FileUpload contained in IBM WebSphere Portal (CVE-2014-0050) for details about
Portal's fix. Patches for WEF and LWF are being released to cover those 
customers that deploy stand-alone applications to WebSphere for production 
use.

Note: WEF 6.1.5 was originally built with Java 1.4.2 to run on versions of 
WebSphere and Portal that are no longer supported. However, the patched 
version of Apache Commons FileUpload requires a Java 1.5 or later run-time. 
Therefore no fixes will be released for WEF 6.1.5 (and WDF 6.1.5) running on a
Java 1.4.2 run-time. All currently supported versions of WebSphere and Portal
use Java 1.5 or later.

CVE ID: CVE-2014-0050

Apache Commons FileUpload and Tomcat are vulnerable to a denial of service.

CVSS Base Score: 5.0

CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/90987 for the 
current score

CVSS Environmental Score*: Undefined

CVSS Vector: (AV:N/AC:L/Au:N/C:N/I:N/A:P)

Affected Products and Versions

All versions of Web Experience Factory, WebSphere Dashboard Framework, and 
Lotus Widget Factory.

Remediation/Fixes

Obtain the APAR appropriate for your version of WEF and WDF from Fix Central.
Those APARs are:

LO80075_WPF6152.zip (also covers WDF 6.1.5.x; must use a Java 1.5 or better 
run-time)

LO80076_WPF7002.zip

LO80077_WEF7014.zip (also covers WDF 7.0.1.x)

LO80078_WEF8003.zip

For LWF please contact IBM support to obtain the appropriate fix.

Note: WEF APARs are cumulative for each major release; if you have installed a
more recent APAR than one of those listed above, then you already have a fixed
vesion of Commons FileUpload. However, you will still need to obtain Portal's
fix if you use WEF for portlet development.

Workarounds and Mitigations

Disable the file upload feature if it is not being used by your application 
(file upload is disabled by default). If you application requires file upload
to be enabled, then you must install one of the noted APARs.
