X-Frame-Options Header未設置 （Clickjacking: X-Frame-Options header missing）

Severity: low

Type: Configuration

CWE:CWE-693 :Protection Mechanism Failure

Description

Clickjacking (User Interface redress attack, UI redress attack, UI redressing) is a malicious te chnique of tricking a Web user into clicking on something different from what the user perceives they are clicking on, thus potentially revealing confidential information or taking control of t heir computer while clicking on seemingly innocuous web pages.

The server didn't return an X-Frame-Options header which means that this website could be at ris k of a clickjacking attack. The X-Frame-Options HTTP response header can be used to indicate whe ther or not a browser should be allowed to render a page inside a frame or iframe. Sites can use this to avoid clickjacking attacks, by ensuring that their content is not embedded into other si tes.

Impact

The impact depends on the affected web application.

Recommendation

Configure your web server to include an X-Frame-Options header. Consult Web references for more information about the possible values for this header.

防止某些重要網(wǎng)頁被其他網(wǎng)站框架導入，可以給頁面增加X-Frame-Options響應頭

asp

<%

response.AddHeader "X-Frame-Options","Deny"

%>

Asp.Net

Response.AddHeader("X-Frame-Options", "Deny");

PHP

header('X-Frame-Options:Deny');

X-Frame-Options響應頭可用值有

DENY：瀏覽器拒絕當前頁面加載任何Frame頁面

SAMEORIGIN：frame頁面的地址只能為同源域名下的頁面

ALLOW-FROM：origin為允許frame加載的頁面地址

如果確認你整個網(wǎng)站都不能被框架，可以直接設置web服務器，增加X-Frame-Options響應頭。IIS如下圖所示，增加http頭

http頭名： X-Frame-Options

http頭值: SAMEORIGIN
