XSS on archive.php #355

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
After delete any file, getSimple goes to:

http://www.site.com/admin/archive.php?upd=del-success&id=myFile

but if we add some extra characters into the URL:

http://www.site.com/admin/archive.php?upd=del-success&id=myFile%3Ciframe%20src=%
22http://www.getsimple.nsn2/theme/Innovation/assets/images/share.png%22%20onnloa
d=%22alert%281%29%22%3E

we can add an iframe to the generated webpage (in this example). So if we can 
modify the HTML generated for archive.php we have a security problem.

This is probably sourced to the error_checking.php which I have complained 
about in another issue.

$_GET['id']is not sanitized in any of the outputs it produces.

Will fix asap.

Great work but it's necessary fix it again. I'd change your new line:

if(isset($_GET['id'])) $errid = ( function_exists( "filter_var") ) ? filter_var 
( $_GET['id'], FILTER_SANITIZE_SPECIAL_CHARS)  : htmlentities($_GET['err']);

by this:

if(isset($_GET['id'])) $errid = ( function_exists( "filter_var") ) ? filter_var 
( $_GET['id'], FILTER_SANITIZE_SPECIAL_CHARS)  : htmlentities($_GET['id']);

See the arguments of htmlentities(). Bye

Another typo in r758 ?
Line 26, GET['$id'] instead of GET['id']

Thanks, one of the plugins in my new editor is not working properly apparently 
and keeps changing stuff.
