### Version:
|
|
> v 1.0
|
|
### Broken Authentication:
|
|
> Broken Access Control is a type of security vulnerability that occurs when a web application fails to properly restrict users' access to certain resources and functionality. Access control is the process of ensuring that users are authorized to access only the resources and functionality that they are supposed to. Broken Access Control can occur due to poor implementation of access controls in the application, failure to validate input, or insufficient testing and review.
|
|
|
|
# Tested On: Windows 11
|
|
|
|
### Affected Page:
|
|
> list.php , manage_user.php
|
|
|
|
> On these page, application isn't verifying the authorization mechanism. Due to that, all the parameters are vulnerable to broken access control and low privilege user could view the list of user's and change any user password to access it.
|
|
|
|
### Description:
|
|
> Broken access control allows low privilege attacker to change password of all application users
|
|
|
|
### Proof of Concept:
|
|
> Following steps are involved:
|
|
1. Visit the vulnerable page: ?page=user/list
|
|
2. Click on Action and Edit the password of Admin
|
|
|
|
|
|
|
|
4. Update the Password and Submit
|
|
|
|
5. Request:
