        Synnergy Laboratories Advisory SLA-2000-15



NAME



       PHPix 1.0.X directory traversal vulnerability



AFFECTED



Linux/UNIX with PHPix 1.0.0/1.0.1/1.0.2



SYNOPSIS



 Synnergy Labs has found a flaw within PHPix that allows a user to successfully

 traverse the filesystem on a remote host, allowing arbitary files/folders to be

 read.





DESCRIPTION



 PHPix is a Web-based photo album viewer written in PHP. It features automatic

 generation of thumbnails and different resolution files for viewing on the fly.

 PHPix Photo Album is available from http://phpix.org



 Synnergy has recently discovered a flaw within PHPix that allow a remote user to

 traverse a directory as a request to the script using the

 $mode=album&album=_some_dir_variable. It is then possible to read any file

 or folder's contents with priviledges as the httpd.



 Example:



 http://target.com/Album/?mode=album&album=..%2F..%2F..%2F..%2F..%2F..%2F..%2F..%2Fetc&dispsize=640&start=0



 The above line if given will output all the directories that are nested within /etc

 directory. Other more sinister content can be revealed from there.





SOLUTION



  The vendors have been informed of the bug. It is advised to wait for the next patched

  version of PHPix to be reelased.
