Summary:
The removal of account is one of the sensitive part of a web application that needs to protect, therefore removing an account should validate the authenticity of the user, however i have found that when removing an account, the system did not require the user to input the account password.
Steps To Reproduce:
1.Create an account on https://alwaysdata.com
2.Go to My account section DELETE ACCOUNT.
3.Click on delete and you will see it will delete the account without any kind of verification or password confirmation.

Impact
Exploit Scenario: The user logins to a shared computer (office, library, cafe) Left the account open. Intruder came and try to delete the users account Intruder can easily delete the account because the system did not protect it by asking the password to validate that the person deleting the account is the real user.

*Title: Critical Security Vulnerability: Unauthorized Account Deletion via Limited Permissions* in [admin.alwaysdata.com]

Summary:*
During my investigation, I discovered a significant security flaw in the system's account management feature.

*Description:*
The system allows users to invite others to manage their accounts with varying permissions, including the ability to enforce two-factor authentication (2FA) before accessing account management privileges.

*Vulnerability Details:*
I identified a vulnerability wherein an invited user, even without sufficient permissions or 2FA activation, can delete the inviting user's account from their own account. This deletion occurs regardless of whether 2FA was enabled during the invitation process.

*Steps to Reproduce the Bug:*
1. Create two accounts.
2. Invite a user to administer your account and enable 2FA.
3. From the invited user's account, delete the account of the inviting user.
4. Observe that the inviting user's account is permanently deleted, despite prior 2FA activation or the absence of sufficient permissions granted.

I sent proof of concept: https://admin.alwaysdata.com/support/77431/374527-bandicam%202024-07-17%2003-48-55-255.mp4

*Impact:*

This security vulnerability poses a significant risk to user accounts within the system. It allows an invited user, even with limited permissions and without activating two-factor authentication (2FA), to permanently delete the account of the inviting user. This action occurs despite security measures initially set up, such as 2FA activation during the invitation process or inadequate administrative permissions granted.

On-click Delete any invitation in [admin.alwaysdata.com]

*Summary:*
The [Create My Own Site] web application system is vulnerable to a click grabbing attack that allows an attacker to trick the user into deleting invitations that they have sent or received without their knowledge.

*Reproduction steps:*
1. Send an invitation to another user.
2. Receive an invitation and try it on the other account.
3. Get the direct link to the invitation and add the /cancel/ command to the URL.
4. Create an HTML proof-of-concept file with the following content:

Programming Language

<a href="https://admin.alwaysdata.com/transfer/Invitation_Number/cancel/----">Click</a>

5. Host this HTML page or send it via link to the victim.
6. Once the victim clicks on the masked link, the invitation is deleted without their explicit consent or knowledge.

An attacker could use their location and attach an HTML file instead of sending a file that the user clicks.

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., http://185.31.40.186/ instead of https://admin.alwaysdata.com/login/?next=/ ). 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 :- https://admin.alwaysdata.com/login/?next=/ Direct IP Access :- http://185.31.40.186/
Reference :-
https://www.nexgi.com/digital-library/direct-ip-access/

Impact:-

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.

Description

*Title:* Two-Factor Authentication Bypass via Support Ticket Creation in [admin.alwaysdata.com]

*Summary:*
A critical security vulnerability has been identified in the [admin.alwaysdata.com]'s account management system where a user with administrative privileges but mandated to use two-factor authentication (2FA) can bypass this requirement by initiating a support ticket under the name of the primary account holder without triggering 2FA.

*Description:*
This vulnerability allows an added user, who is supposed to be restricted by 2FA, to perform actions appearing as the primary account holder by submitting support tickets. This circumvents the security protocol intended to protect sensitive account operations via 2FA, potentially leading to unauthorized actions without the account holder's consent or knowledge.

*Steps to Reproduce:*
1. Create two user accounts, Account A (primary) and Account B.
2. From Account A, add Account B as another user with full administrative privileges but enforce 2FA on actions.
3. Log into Account B.
4. Navigate to the support section and initiate a support ticket, selecting Account A as the affected account.
5. Submit the ticket without being prompted for 2FA verification.

I sent a proof of concept : https://admin.alwaysdata.com/support/77431/367474-VID-20240423-WA0000.mp4

*Impact:*
The primary account holder's security is compromised as the added user can perform sensitive operations under their guise without completing the necessary 2FA checks. This vulnerability may lead to unauthorized access and control over the primary account's sensitive functions and data.

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 https://admin.alwaysdata.com/login/ Enter your Email Click On Forget Password
2- intercept burp and send request to intruder
3- make payload and start attack

*Title:* Clickjacking (On-click) Vulnerability in Support Ticket Attachment Deletion in [admin.alwaysdata.com]

*Summary:*
The support ticket system of the web application is vulnerable to a clickjacking attack that allows an attacker to trick a user into deleting attachments from their support tickets unknowingly.

On-click Delete any attachment for users in support tickets Delete any attachment for users in technical support tickets

*Steps to Reproduce:*
1. Create a support ticket in the application.
2. Attach a file to the support ticket.
3. Obtain the direct link of the attachment and append the /delete/ command to the URL.
4. Create an HTML proof-of-concept file with the following content:

html

  <a href="https://admin.alwaysdata.com/support/----/delete/----">click</a>

5. Host this HTML page or send it via link to the victim.
6. Once the victim clicks on the disguised link, the attachment is deleted without their explicit consent or knowledge.

An attacker can use his location and attach an html file instead of sending a file that the user clicks on.

*Impact:*
The exploit enables unauthorized deletion of any attachment from user-created support tickets. This can result in loss of critical data and potential breach of information security, affecting data integrity and user trust.

This is in addition to this report as I explained in another way but I remembered now that the attacker had to delete any technical support ticket in the way I explained in this report

Hi Team,

I hope this email finds you well.
I am Ali Haider, a security researcher and a penetration tester. I have been a bug bounty hunter for almost 2 years now. I always enjoyed the challenge of finding vulnerabilities, as it always felt like a great achievement to find them. I wanted to bring to your attention a Open Redirection Vulnerability I encountered while using your website.

Hello Web Security
Severity: Medium
Domain: https://admin.alwaysdata.com

Description :
A security researcher discovered that after resetting a password, the user was automatically logged in. As such, compromising a legitimate password reset link (via referrer token leakage or a similar issue) could lead to compromising the account since the user would not be forced to log in after resetting their password.

Proof Of Concept:
1.Go to this website:(https://admin.alwaysdata.com)
2.Send the password reset link to your email.
3.Go to your email and open the link.
4.Set a new password.
5.Boom.Automatically logged in.

Fix:
OWASP forgot password recommendations(https://www.owasp.org/index.php/Forgot_Password_Cheat_Sheet) suggest a better approach, which we have now implemented.

Thanks.

Summary:

The vulnerability was discovered during security testing when the directory listing feature of a web server listed the xapian-7.3.so file among its contents. Given that xapian-7.3.so is a shared object file for Xapian, a highly versatile search engine library, its exposure poses significant security risks. This file contains compiled code that is executed within the server context, making it a critical component of the search functionality offered by the hosting server.

Impact:

The inadvertent exposure of xapian-7.3.so could have several potential impacts:

Information Disclosure: Malicious actors could download and analyze the shared object file to uncover proprietary algorithms or specific implementations of the search engine, leading to a competitive disadvantage or privacy violations.
Security Vulnerability Exploitation: If any vulnerabilities exist within the specific version of the file, attackers could develop exploits to compromise the server or manipulate search engine results.
Service Disruption: In scenarios where the file is not merely exposed but also manipulable or deletable, attackers could disrupt the search functionality, leading to denial of service.

Mitigation

Immediate steps should be taken to mitigate the vulnerability:

Disable Directory Listing: Configure the web server to disable directory listing globally or specifically within directories not intended for public access.
Access Controls: Implement proper access controls to ensure that sensitive files, such as xapian-7.3.so, are not accessible via the web server to unauthorized users.
Security Patches: Ensure that all components, especially exposed ones like xapian-7.3.so, are regularly updated to the latest versions to mitigate known vulnerabilities.
