CWE-670 控制流实现总是不正确 类漏洞列表 70

This code queries a server and displays its status when a request comes from an authorized IP address.

$requestingIP = $_SERVER['REMOTE_ADDR']; if(!in_array($requestingIP,$ipAllowList)){ echo "You are not authorized to view this page"; http_redirect($errorPageURL); } $status = getServerStatus(); echo $status; ...

In this example, the programmer has indented the statements to call Do_X() and Do_Y(), as if the intention is that these functions are only called when the condition is true. However, because there are no braces to signify the block, Do_Y() will always be executed, even if the condition is false.

if (condition==true) Do_X(); Do_Y();
