Product:

=======================

AjaxExplorer v1.10.3.2

Manage server files through simple windows like interface.

Vulnerability Type:

=======================

Remote Command Execution

CSRF

Persistent XSS

CVE Reference:

==============

N/A

Vulnerability Details:

=====================

AjaxExplorer has command terminal feature where you can move, copy, delete files etc... also lets a user save commands in a

flat file named "terminal" under their user profile "/http://ift.tt/1O4p99b".

e.g.

copy [FILEPATH + FILENAME] [FILEPATH]

create [FILEPATH + FILENAME]

Since AjaxExplorer also suffers from CSRF vulnerability we can exploit the application by first creating an .htaccess file with an

"allow from all" directive to bypass access restrictions, next create arbitrary PHP files for remote command execution purposes.

This exploit will require two consecutive HTTP requests, so we need to target an iframe to stay on same page until exploit is completed.

Exploit code(s):

===============

1) first POST request creates .htaccess file so we can bypass directory browsing restrictions.

2) second POST writes our remote command execution file we will then access to execute commands on the victim system.

The below P:/ for "strPath" form value is for "Profile"

method="post">

method="post">

Now we can access and run arbitrary cmds.

ofile/terminal.php?cmd=c:\\Windows\\system32\\calc.exe

/////////////////////////////////////////////////////

Here is another way to RCE this application... first create PHP file then edit.
