Allow All Content Security Policy?

Question

Is it possible to configure the Content-Security-Policy to not block anything at all? I\'m running a computer security class, and our web hacking project is running into iss

Answer 1

Here's the htaccess code to allow everything in CSP

Header add Content-Security-Policy "default-src *  data: blob: filesystem: about: ws: wss: 'unsafe-inline' 'unsafe-eval' 'unsafe-dynamic'; script-src * data: blob: 'unsafe-inline' 'unsafe-eval'; connect-src * data: blob: 'unsafe-inline'; img-src * data: blob: 'unsafe-inline'; frame-src * data: blob: ; style-src * data: blob: 'unsafe-inline'; font-src * data: blob: 'unsafe-inline';"

Answer 2

The best way would be not applying any policy.

But to answer your question, an "allow all policy" would probably be:

default-src * 'unsafe-inline' 'unsafe-eval' data: blob:; 

Note: untested

Answer 3

For people who still want an even more permissive posts, because the other answers were just not permissive enough, and they must work with google chrome for which * is just not enough:

default-src *  data: blob: filesystem: about: ws: wss: 'unsafe-inline' 'unsafe-eval' 'unsafe-dynamic'; 
script-src * data: blob: 'unsafe-inline' 'unsafe-eval'; 
connect-src * data: blob: 'unsafe-inline'; 
img-src * data: blob: 'unsafe-inline'; 
frame-src * data: blob: ; 
style-src * data: blob: 'unsafe-inline';
font-src * data: blob: 'unsafe-inline';

Answer 4

It's not secure at all, but as staring point the real allow all policy is:

default-src * 'unsafe-inline' 'unsafe-eval'; script-src * 'unsafe-inline' 'unsafe-eval'; connect-src * 'unsafe-inline'; img-src * data: blob: 'unsafe-inline'; frame-src *; style-src * 'unsafe-inline';
