 98 Closed Poor Error Handling zain812 Task Description

It was observed that the application exhibits poor data handling practices, which could lead to potential security vulnerabilities. Specifically:

Reflected Input in 404 Error Page: When a user navigates to a non-existent URL ====(https://www.alwaysdata.com/%69%6e%73%63%72%69%70%74%69%6f%6e%2f%79%6f%75%5f%61%72%65%5f%68%61%63%6b%65%64%5f%62%79%5f%7a%61%69%6e),==== the application returns a 404 error page. However, any additional text or encoded characters appended to the URL (e.g., malicious payloads) are directly reflected in the error message without proper sanitization or encoding.

Example: Accessing the crafted URL 1: https://www.alwaysdata.com/%69%6e%73%63%72%69%70%74%69%6f%6e%2f%79%6f%75%5f%61%72%65%5f%68%61%63%6b%65%64%5f%62%79%5f%7a%61%69%6e

2: https://www.alwaysdata.com/yOu_Are_hAckEd_by_zaIN_Ul_AbideeN

Result:

====404 - Page not found
The page /yOu_Are_hAckEd_by_zaIN_Ul_AbideeN could not be found. If you believe this is an error on our part, please let us know. Back ====

====Risk:==== This issue indicates a lack of proper input validation and output encoding, making the application vulnerable to Reflected Cross-Site Scripting (XSS) attacks. An attacker could craft malicious URLs containing scripts (e.g., <script>alert('XSS')</script>), which, if clicked by another user, could execute arbitrary JavaScript in their browser.

**Recommendation:**

Input Validation:

Validate and sanitize all user-supplied inputs before processing them.
Reject or encode unexpected characters in URLs.

==Output Encoding:
==
Ensure that any data rendered on error pages is properly encoded to prevent the execution of scripts.

==Customized 404 Page:==

Use a generic 404 error page that does not reflect user input back in the response.

==Security Testing:
==
Perform a thorough security assessment to identify and mitigate XSS or other injection vulnerabilities.

 97 Closed Password Reset Email Flooding (No Rate Limiting) zain812 Task Description

__**Observation:**__

During testing of the web application, I found that the "Forgot Password" functionality
lacks proper rate-limiting. After entering my email address to reset my password multiple
times in quick succession (more than 61 times with intervals of 30-40 Seconds), the
system sent all the reset emails without any restriction. The application does not
implement a time-based threshold (e.g., 10 or 20 minutes) between password reset
requests, which makes it vulnerable to abuse

====Risk:==== Medium / (Sometimes or in some scenario/cases it will be High

====Impact:====

• mail Flooding: An attacker could repeatedly request password reset emails for any user account, causing their inbox to be flooded with reset emails. This can lead to denial of service for the victim by cluttering their inbox or, in some cases, may trigger email provider throttling, preventing legitimate emails from reaching the user.
• Account Lockout Exploit: Although this vulnerability does not directly lead to unauthorized access, it could be combined with social engineering attacks, where victims are confused by multiple reset emails, potentially tricking them into taking malicious actions.

__**Recommendation:**__

•Implement Rate Limiting: Add a limit on how many passwords reset requests can be sent within a specific time frame (e.g., 3 attempts per hour).

•Time-based Delay: Enforce a minimum time interval (e.g., 10-20 minutes) between consecutive password reset requests for the same email address.

•CAPTCHA Implementation: Add CAPTCHA to the password reset functionality to prevent automated abuse by bots.

•Alert Mechanism: Notify users if multiple password reset requests are made in a short period to alert them to potential malicious activity.

•Logging & Monitoring: Implement logging to monitor multiple reset attempts and detect any abuse patterns, which can trigger additional security measures.
