paFileDB SQL Injection
------------------------------------------------------------------------
SUMMARY
" <http://www.phparena.net/pafiledb.php> paFileDB is designed to allow web
masters 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 administration center, and fill out a form to add
a file. paFileDB lets you edit and delete the files too."
The paFileDB product has been found to contain an SQL Injection
vulnerability.
DETAILS
Vulnerable Systems:
* paFileDB version 3.1 and prior
SQL injection:
The $start variable found in the viewall.php and category.php file is
vulnerable for SQL injection attack as it uses the following code:
if ($sortby == "name") {
$result = $pafiledb_sql->query($db, "SELECT * FROM
$db[prefix]_files WHERE file_pin = '0' ORDER BY file_name
ASC LIMIT $start,20", 0);
}
if ($sortby == "date") {
$result = $pafiledb_sql->query($db, "SELECT * FROM
$db[prefix]_files WHERE file_pin = '0' ORDER BY file_time
DESC LIMIT $start,20", 0);
}
if ($sortby == "downloads") {
$result = $pafiledb_sql->query($db, "SELECT * FROM
$db[prefix]_files WHERE file_pin = '0' ORDER BY file_dls
DESC LIMIT $start,20", 0);
}
if ($sortby == "rating") {
$result = $pafiledb_sql->query($db, "SELECT * FROM
$db[prefix]_files WHERE file_pin = '0' ORDER BY
(file_rating/file_totalvotes - 1) DESC LIMIT $start,20", 0);
}
Examples of SQL injections:
http://example.com/[pafiledb_dir]/pafiledb.php?action=viewall&start='
&sortby=rating
http://example.com/[pafiledb_dir]/pafiledb.php?action=category&start='
&sortby=rating
Sample error message:
paFileDB was unable to successfully run a MySQL query.
MySQL Returned this error: You have an error in your SQL syntax near
'\',20' at line 1 Error number: 1064
The query that caused this error was: SELECT * FROM pafiledb_files WHERE
file_pin = '0' ORDER BY
