SEC Consult SA-20090917-0 :: RADactive I-Load Multiple Vulnerabilities
SEC Consult Security Advisory < 20090917-0 >
title: Multiple Vulnerabilities in RADactive I-Load
products: RADactive I-Load
vulnerable version: <= I-Load 2008.2.4.0
fixed version: I-Load 2008.2.5.0
by: S. Streichsbier / SEC Consult / www.sec-consult.com
I-Load is an ASP.NET component explicitly created to manage image uploading
within ASP.NET applications. Unlike other image manipulation libraries,
I-Load uses a sophisticated graphical interface which allows the uploading,
resizing, cropping and rotating of photos.
The I-Load component contains multiple vulnerabilities which are described
* Path Disclosure:
The WebCoreModule.ashx script prints the absolute path of the folder
images are saved to, in some requests and responses. This can help an
with the exploitation of the also existing file disclosure vulnerability.
* Cross Site Scripting:
Most of the parameters used by WebcodeModule.ashx start with two
"__" which disables the build-in ASP.NET "Anti Cross Site Scripting"
functionality. Some parameters are not sufficiently validated and can be
* File Disclosure:
WebCoreModule.ashx can be exploited by the means of path traversal to read
arbitrary files on the server given that the file permissions allow it. An
attacker is able to gain sensitive data such as configuration files
(e.g. Web.config), the whole source code of the application or other
data on the server.
* Arbitrary File Upload:
It is potentially possible to upload an arbitrary file using the I-Load
Webcontrol with a user-defined file extension. The filename itself is
dynamically generated, but it is possible to reproduce that parameter in
advance. The file remains on the server for a very short period of time.
Nevertheless, during this time frame it could be possible to execute
and thus compromise the affected server.
Proof of Concept:
SEC Consult will not release proof of concept exploits to the public.
RADactive I-Load 2008.2.4.0
