Use the following code:
This code allows you to hide the HTML code in front of the page, and you can only see the code that executes inside the JavaScript statement after you run it.
And after refreshing, you can no longer see the source code of the site, and can use JavaScript to execute arbitrary code.
The best time to hang a horse is to be missed.
Test method:
Save the above code for an HTML page.
If you only see the above time, it will prove that your IE also has this
Any file Upload vulnerability
File Upload Vulnerability (Upload Attack) is because the file Upload function implementation code does not strictly limit the user's uploaded file suffix and file type, resulting in allowing attackers to upload arbitrary php files to a directory that can be accessed through the Web, and to pass these files to the PHP interpreter.

As a webmaster, in fact, as early as a few days ago saw the relevant information news: ImageMagick was a high-risk vulnerability (cve-2016-3714), hackers and other attackers through this vulnerability can execute arbitrary commands, and ultimately steal important information to obtain server control. Want to be to the server, the degree of harm is still relatively large.

Memcached is a set of distributed cache systems. It stores data in memory in the form of key-value (key-value pairs), which are often read frequently by the application. Because the in-memory data is read far more than the hard disk, it can be used to speed up the application's access.Causes of vulnerability:Due to memcached security design flaws, clients can read and modify server cache content without authentication after connecting to the memcached server.
