Hello Full-Disclosure!
I want to warn you about security vulnerabilities in MiniManager for Project
MANGOS.
-----------------------------
Advisory: Vulnerabilities in MiniManager for Project MANGOS
-----------------------------
URL: http://websecurity.com.ua/4061/
-----------------------------
Timeline:
17.03.2010 - found vulnerabilities.
23.03.2010 - disclosed at my site.
24.03.2010 - informed developers.
-----------------------------
Details:
These are Insufficient Anti-automation and Denial of Service
vulnerabilities.
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:
http://site/libs/captcha/CaptchaSecurityImages.php?width=150&height=100&characters=2
Captcha bypass is possible as via half-automated or automated (with using of
OCR) methods, which were mentioned before (http://websecurity.com.ua/4043/),
as with using of session reusing with constant captcha bypass method
(http://websecurity.com.ua/1551/), which was described in project Month of
Bugs in Captchas.
DoS:
http://site/libs/captcha/CaptchaSecurityImages.php?width=1000&height=9000
With setting of large values of width and height it's possible to create
large load at the server.
Vulnerable MiniManager for Project MANGOS 0.15 and previous versions.
Best wishes & regards,
MustLive
