Vulnerabilities in CCMS

Hello Bugtraq!

I want to warn you about security vulnerabilities in system CCMS - Clan
Content Management System.

In this advisory I'm continue to inform readers of mailing lists about
vulnerable web applications which are using CaptchaSecurityImages.php. If
you read Bugtraq you can saw the letter, from which it's clearly seen, that
web developers ignore advisory about holes in CaptchaSecurityImages.php
itself, and only draw attention on advisories about their specific web
applications. And I answered on this letter
(http://www.securityfocus.com/archive/1/511023). So, as I already wrote to 
the list, it's only way to draw attention of web developers to these issues.

Advisory: Vulnerabilities in CCMS
URL: http://websecurity.com.ua/4097/ 
Affected product: CCMS 1.0.

17.03.2010 - found vulnerabilities.
03.04.2010 - disclosed at my site.
06.04.2010 - informed developers.

These are Insufficient Anti-automation and Denial of Service

The vulnerabilities exist in captcha script CaptchaSecurityImages.php, which
is using in this system. I already reported about vulnerabilities in
CaptchaSecurityImages (http://websecurity.com.ua/4043/). 

Insufficient Anti-automation:


Captcha bypass is possible via half-automated or automated (with using of
OCR) methods, which were mentioned before (http://websecurity.com.ua/4043/). 



With setting of large values of width and height it's possible to create
large load at the server.

Best wishes & regards,
