Vendor notified at and partial patch:
http://forums.xmbforum.com/viewthread.php?tid=754523
firstly the input validation at xmb.php:
foreach ($global as $num => $array) {
if (is_array($array)) {
extract($array, EXTR_OVERWRITE);
}
}
this should put to not overwrite any variables cause
it overwrite server set variables too. this creates problems
when user submits a additional field in form:
<input type="text" name="_SERVER[REMOTE_ADDR]" value="555.555.555.555">
secondly there is a case of sql injection in include/u2u.inc.php
line ~491:
Code:
$in = '';
foreach ( $u2u_select as $value ) {
if ( $GLOBALS['type'.$value] != 'outgoing' ) {
$in .= ( empty( $in ) ) ? "$value" : ",$value";
}
}
...
$db->query( "UPDATE $table_u2u SET readstatus='no' WHERE u2uid IN($in) AND owner='$self[username]'" );
the variable $in is not actually validated and could and will cause problems if not fixed.

Hello and thank you all for this information. I was given the opportunity to take over XMB development last year. Fixing this bug was one of my first official acts.
I could not find the original notification about this bug, so I have forwarded the original link to the new CVE vendor statement.
I will personally handle any new security notices for XMB. You are welcome to re-test the new versions 1.9.10 and 1.9.11.
Enjoy |
