Description

Hello 3APA3A!

I want to warn you about vulnerabilities in Moxiecode File Manager (MCFileManager). This is commercial plugin for TinyMCE. It concerns as MCFileManager, as all web applications which have MCFileManager in their bundle.

These are Arbitrary File Uploading vulnerabilities, which lead to Code Execution on IIS and Apache web servers.


Affected products:

Vulnerable are Moxiecode File Manager 3.1.5 and previous versions.


Affected vendors:

Moxiecode http://www.moxiecode.com


Details:

Arbitrary File Uploading (WASC-31):

Execution of arbitrary code is possible due to bypass of program's security filters (on IIS and Apache web servers).

Code will execute via file uploading. Program is vulnerable to three methods of code execution:

  1. Via using of symbol ";" (1.asp;.txt) in file name (IIS).

  2. Via "1.asp" in folder name (IIS).

  3. Via double extension (1.php.txt) (Apache with special configuration).


Timeline:

2013.03.31 - briefly informed developer (together with other issues related to TinyMCE). 2013.04.01 - informed developer in detail. 2013.04.02 - announced at my site. 2013.04.04 - the developer planned to fix these holes in new version in nearest days. 2013.05.17 - disclosed at my site (http://websecurity.com.ua/6413/).
