 53  Lack of Email Confirmation During Account Creation Closed05.06.2024 Task Description

Severity: High

Vulnerability Description:
The website allows users to create accounts without verifying their email addresses. This practice poses significant security and usability risks.


Spam and Fake Accounts:

Malicious users can create multiple fake accounts, leading to spam and abuse of the platform.
Automated scripts (bots) can exploit this vulnerability to flood the system with fake accounts, overwhelming resources and degrading performance.
Account Security:

Unauthorized users can create accounts using someone else's email address, potentially leading to privacy breaches and unauthorized access to personal information.
Genuine users might be unable to access their accounts if their email addresses are misused by others.

Communication Failures:

Users may not receive important notifications, updates, or password reset instructions, leading to poor user experience and support issues.

Reputation and Trust:

The lack of basic security measures can lead to loss of trust among users and damage the website's reputation.
Users might perceive the platform as insecure and unreliable, leading to reduced user retention and engagement.

 52  Direct IP Access of the Domain on HTTP Closed05.06.2024 Task Description

Hello Team,
My Name Is Pawan Yadav, a cyber security researcher from India. While testing one of your domains, I have found a vulnerability in your site.

Here is the detailed report:

Vulnerability Description :-
Direct IP access refers to the ability to access a website or service directly via its IP address
rather than its domain name (e.g., instead of ). Direct IP
access can bypass certain security controls implemented at the domain level, potentially
exposing sensitive information or allowing unauthorized access to resources.

Attack Vector :-
An attacker can directly access the web application by using its IP address, bypassing domain-
based security controls such as Web Application Firewalls (WAFs), IP filtering, or access controls
based on the domain name.
Domain :- Direct IP Access :-
Reference :-


Denial of Service : Direct IP-address Access has its own set of issues. For starters, it increases
the chances to encounter a Distributed Denial of Service attack.
Data Interception: Attackers can intercept and read sensitive information transmitted between
the server and clients, such as login credentials, personal information, and payment details.
Man-in-the-Middle Attacks: This vulnerability enables attackers to intercept and potentially alter
the communication between the server and client, leading to unauthorized data modification or
injection of malicious content.
Loss of User Trust: A lack of HTTPS can undermine the trust and credibility of the website among
its users, potentially leading to decreased user engagement and conversions.

 51  Multiple Free Public Cloud accounts obtained by a singl ...Closed25.04.2024 Task Description


Alwaysdata allows users to create a Free Public Cloud (100MB) account. Each user is limited to having only one Free Public Cloud (100MB account. However, I discovered that a user can bypass this restriction and obtain multiple Free Public Cloud (100MB) accounts by asking other users to create a new free account and then transfer ownership of that account to them.

Reproduction Steps

1. User A creates a new Free Public Cloud (100MB) storage account
2. User B creates a new Free Public Cloud (100MB)storage account
3. User B transfers ownership of their account to User A through:
4. User A now has two Free Public Cloud (100MB)storage accounts (their original account and the one transferred from User B)
5. This process can be repeated with same user B for unlimited times to accumulate unlimited no of free accounts.


By exploiting account ownership transfers, a user can essentially obtain unlimited free storage, potentially leading to loss for alwaysdata


Implement additional checks and restrictions to prevent users from obtaining multiple free accounts through ownership transfers. Possible mitigations could include:

1. Limiting the number of free accounts a user can own, regardless of the acquisition method (creation or transfer).
2. Disallowing ownership transfers for free accounts or requiring explicit approval from the service provider.
3. Automatically consolidating multiple free accounts under the same user into a single account, preserving the total storage limit.

Proof of Concept:

I was able to accumulate 3 free accounts for user: poc image :

 49  Vulnerability Report: Lack of Rate Limiting on Password ...Closed24.04.2024 Task Description

The website does not implement rate limiting on password reset links, allowing an attacker to repeatedly request password reset links for any account. This could lead to account takeover through brute-force attacks.

Description When an attacker gains access to a target account's email address, they can repeatedly request password reset links without any rate limiting in place. This allows them to flood the target's email inbox with reset links, making it difficult for the legitimate user to identify and use the valid reset link. Additionally, the attacker can automate this process, increasing the efficiency of the attack.

Impact Account Takeover: Attackers can potentially take over user accounts by flooding their email inbox with reset links, making it easier to intercept a valid reset link and gain unauthorized access.
User Disruption: The flood of reset links can disrupt the user's ability to use their email normally, causing inconvenience and potential confusion.

Recommendations Implement rate limiting on password reset requests to prevent brute-force attacks.
Limit the number of password reset links that can be requested per minute per IP address or account.
Implement CAPTCHA or other mechanisms to distinguish between automated and legitimate requests.

Steps to Reproduce 1- Go To This Link Enter your Email Click On Forget Password
2- intercept burp and send request to intruder
3- make payload and start attack

I have found an interesting flaw where an attacker can change the account password without knowing the old password

When the user requests a password reset link, it accesses the activity log inside the account and this bug can be exploited by an attacker

Steps to reproduce the bug :

1-Create a new account on []
2-log in to your account
3-request the password reset link from another browser
4-you will notice that the password reset link you requested has arrived in the activity log

Impact :
If the attacker hijacks the session or gains access to the user account, he can request a password reset link and the link will reach him in the Account Activity Log, from which he can reset the account password without knowing the old password

 42  Git Configuration Exposure Closed27.03.2024 Task Description

Vulnerability Git Configuration Exposure

Severity Level Critical

Vulnerable Domain:

1. Executive Summary: The Git Configuration Exposure vulnerability poses a significant threat to web applications, allowing unauthorized access to sensitive source code repositories. Through the discovery of exposed .git/ directories, attackers can leverage this information to extract the complete source code of a website. This breach can result in the unauthorized disclosure of sensitive information, including proprietary code, configuration files, and other critical assets. This executive summary outlines the discovery, impact, and recommended mitigation strategies for this vulnerability.

2. Overview The vulnerability arises when an attacker identifies the presence of a .git/config directory. This discovery provides a direct route to the Git repository of a web application. By employing specialized tools such as those available in Kali Linux, an attacker can download the entire source code of the website, gaining access to proprietary code, scripts, and configuration files. The consequences of this exposure extend beyond the compromise of intellectual property to potential security risks and the unauthorized retrieval of sensitive information.

3. Vulnerability Discovery The vulnerability is discovered through directory research, where the presence of a .git/config directory is identified. Attempts to access this directory reveal the underlying Git repository, providing a pathway for unauthorized individuals to exploit the exposed version control system.

4. Impact Unauthorized Access to Source Code: Attackers can download the complete source code of the website, enabling the extraction of proprietary code, scripts, and configuration files.
Intellectual Property Theft: The compromise of source code poses a significant risk of intellectual property theft, potentially leading to unauthorized use or distribution.
Sensitive Information Exposure: The extracted source code may contain sensitive information, such as API keys, database credentials, and other critical data, compromising the overall security of the web application.

5. Mitigation Strategies

Git Configuration Hardening: Implement strict access controls and configure Git repositories to restrict access to authorized personnel only.
Directory Listing Prevention: Disable directory listing to prevent the exposure of .git directories during web server configuration.
Git Repository Hosting Security: If using third-party Git repository hosting services, ensure proper access controls are in place, and sensitive information is not exposed.

6. Steps To Reproduce:

1- Visit this URL = 2- You can see the Config file.
3- Using the gitdumper tool, in which I was able to dump the whole .git directory.
4- Boom!! I have access to the whole source code of the application.
4- Command
–> ./ your/any/directory/of/kali

Important Note: Another thing I'd like to share with you is that I haven't extensively exploited this vulnerability. Otherwise, I could have easily downloaded the entire website's source code, which often contains many and many sensitive information.

Proof of concept As you can see that I am able to access the entire source code. Now, if I put the output command to my command, I can download the whole source code.

 38  Bug Title: Prototype Pollution Vulnerability Report Closed19.03.2024 Task Description

Bug Title: Prototype Pollution Vulnerability Report
Weakness: Prototype Pollution
Hello Web Security Team,

I am reporting a security vulnerability on the website The website is affected by prototype pollution due to the usage of an outdated jQuery version.

The website uses jQuery version 1.12.4, which is susceptible to prototype pollution. This vulnerability allows an attacker to inject properties into Object.prototype, affecting all objects across the application. Notably, the "deep" version of jQuery $.extend is impacted.

Steps To Reproduce:
1. To check if the application is vulnerable to prototype pollution attack we can use the below command:

command: $.extend(true, {}, JSON.parse('{"__proto__":{"polluted":"hacked"}}'));

2. Now let's open the application URL: and enter into the developer options Console tab and paste the command and hit enter.
Notice that the result contains an option with polluted: hacked


Prototype pollution introduces a severe risk to the application. An attacker, upon exploiting this vulnerability, can manipulate default values for options passed to functions with an "options" argument—a common pattern in JavaScript applications. The impact escalates based on the application's use of such options, potentially leading to unauthorized modifications and alterations in the application's behavior.

Supporting Material/References: The vulnerability has been verified on jQuery version 1.12.4, and it is likely to affect older versions.
The issue is present when using Chrome latest version.

Update latest version of jquery 3.7.1 is the best remediation as it has no known vulnerabilities at the time of this writing

 35  Git Folder Forbidden Bypass Closed22.02.2024 Task Description

During google search I have found an Open sensitive git directory.
Git metadata directory (.git) was found in this folder. An attacker can extract sensitive information by requesting the hidden metadata directory that version control tool Git creates. The metadata directories are used for development purposes to keep track of development changes to a set of source code before it is committed back to a central repository (and vice-versa). When code is rolled to a live server from a repository, it is supposed to be done as an export rather than as a local working copy, and hence this problem.
Vulnerable URL:- (403 forbidden)
bypass (403 forbidden)

These files may expose sensitive information that may help a malicious user to prepare more advanced attacks.
Remove these files from production systems or restrict access to the .git directory. To deny access to all the .git folders you need to add the following lines in the appropriate context (either global config, or vhost/directory, or from .htaccess)

 33  Privilege Escalation in - Academic ...Closed16.02.2024 Task Description


A vulnerability has been discovered in the student management system, which allows a normal user account to bypass access controls. ANY registered low-level user, with no knowledge or involvement in a class, can globally detach any student involved just by manipulating the UID. Even without tutorship/academic privileges and regardless of tutor access control.


A malicious attacker could fuzz predictable UID values and remove multiple students, abusing the privesc as a nuisance.


1) First, we logged in to an actual tutor account where I've added a few students. Next, I take note of the IDs of each student involved.

2) Then, I logged out and just to validate this exploit, I would create a NEW account.

3) This is the vulnerable endpoint:<USER_ID>

I replaced the <USER_ID> param with the various IDs I recorded from the tutor account.

4) Visit these URLs on the new account and observe the results.

5) Then, log out and re-login to the tutor account. Visit and confirm poc validity.


Implement proper access controls and role-based permissions to restrict normal users from utilizing global admin/tutor privileges. Conduct a thorough review of the authentication and authorization processes to ensure that no other similar vulnerabilities exist.

During testing of the login process on the platform, I observed that user credentials (email and password) are transmitted in plain text or with minimal obfuscation. While the CSRF token appears to be encrypted, the email and password fields are transmitted without proper encryption, making them susceptible to interception and potential exploitation by malicious actors.

Steps to Reproduce:

Navigate to the login page.
Enter valid login credentials (email and password).
Intercept the login request using a tool such as Burp Suite.
Analyze the intercepted request to observe that the email and password are transmitted in plain text or with minimal obfuscation, while the CSRF token is encrypted.


Unauthorized Access: Attackers can intercept and extract user credentials, potentially leading to unauthorized access to user accounts and sensitive information.
Account Takeover: Malicious actors can exploit the vulnerability to gain unauthorized control over user accounts, posing a risk to the security and privacy of affected users.
Data Breach: The transmission of credentials in plain text exposes users' sensitive information to interception, increasing the risk of data breaches and privacy violations.


The severity of this vulnerability is considered critical due to the potential for unauthorized access, account takeover, and data breaches. It undermines the security and trustworthiness of the platform and poses significant risks to its users.
Recommendation for Mitigation:
To mitigate this vulnerability, I recommend the following actions:

Implement HTTPS encryption for all pages, especially those involving sensitive operations like login.
Ensure that all user credentials, including email and password, are transmitted securely using encryption techniques such as TLS.
Implement strong authentication mechanisms, such as multi-factor authentication (MFA), to enhance the security of user accounts.
Conduct regular security assessments and audits to identify and address vulnerabilities in the platform's security controls.
I believe that addressing this vulnerability promptly is crucial to ensuring the security and privacy of users' accounts and sensitive information on the platform. I am available to provide further assistance or clarification on this matter if needed.

Thank you for your attention to this report, and I look forward to your prompt response and actions to address this vulnerability.
