Rule:

WEB-COLDFUSION 'publish' example app addcontent.cfm access

--
Sid:

907

--
Summary:

Attempted to access a vulnerable example application on a Coldfusion 4.x 
server.  This 'Web Publish Example Script' can be exploited to allow the 
attacker to upload an arbitrary file to the server.

--
Impact:

Serious: The vulnerability allows custom code to be uploaded to the server.

--
Detailed Information:

ColdFusion (Macromedia, formerly Allaire) web servers have several
default Example applications installed that have vulnerabilities.  The
'Web Publish Example script' application can be exploited to allow the
uploading of arbitrary files.

See Macromedia Security Bulletin (MPSB01-08) for complete information.

--
Affected Systems:

ColdFusion versions 2.x, 3.x, 4.x for Windows
ColdFusion versions 4.x for Solaris, HP-UX
ColdFusion versions 4.5.x for Linux
Expression Evaluator Patch (ASB99-01)

--
Attack Scenarios:

The web application allows file uploading via a URL like this:

http://www.target.com/CFDOCS/exampleapps/publish/admin/addcontent.cfm

Once the file has been uploaded, it can be executed by crafting a 2nd
URL to the uploaded file.

--
Ease of Attack:

Trivial

--
False Positives:

If you're using ColdFusion example code, you'll trigger this alert.

--
False Negatives:

Unknown

--
Corrective Action:

Delete all example code.  This is one of several significant
vulnerabilities that are exploitable if the example code is left on a
production server.
