Look for unquoted variables in sql queries, in example:
sql_query("UPDATE ".$prefix."_downloads_downloads SET downloadratingsummary=$finalrating,totalvotes=$totalvotesDB,totalcomments=$truecomments WHERE lid='$lid'", $dbi);
should be:
sql_query("UPDATE ".$prefix."_downloads_downloads SET downloadratingsummary='$finalrating',totalvotes='$totalvotesDB',totalcomments='$truecomments' WHERE lid='$lid'", $dbi);
As you can see single quotes were added to the variables

Another example:
$result=sql_query("select rid, name, url from ".$prefix."_related where tid=$topicid", $dbi);
should be:
$result=sql_query("select rid, name, url from ".$prefix."_related where tid='$topicid'", $dbi);
notice $topicid was enclosed between single quotes.

This particular query attempts to grab 3 values from a database table, an id, a name and a url,
the id is a numerical value:
while(list($rid, $name, $url) = sql_fetch_row($result, $dbi)) {
Results are returned in the format $value, since one of the values is a number we add a
php function to make sure only numbers are used, in this case we use intval(), in values
that return emails & urls we can use another function, in this case stripslashes(),
the result line would now change to:
while(list($rid, $name, $url) = sql_fetch_row($result, $dbi)) {
$rid = intval($rid);
$url = stripslashes($url);

There are many more functions one can use to check what gets passed through a
variable but these should help make the files more secure, anyway here's one more:
Let's say that from our example we know $name will have a maximum allowed
character limit of 12, we can make sure that limit is not exceeded in one
of several ways, in this case we'll use substr() so the above will now be:
while(list($rid, $name, $url) = sql_fetch_row($result, $dbi)) {
$rid = intval($rid);
$name = substr("$name", 0,12);
$url = stripslashes($url);

In the case of variables for titles and descriptions you could mix stripslashes() with FixQuotes() , but only when inserting data into a table, if extracting only use stripslashed() since FixQuotes() will duplicate all single quotes, in example:
$description = stripslashes(FixQuotes($description)); - for data to be inserted to a table.
$description = stripslashes($description); - for data to be extracted from a table.

Variables list


The following are some of the variables that deal with numerical values, you should secure them with the intval() function.
