Description

A vulnerability exists on the https://admin.alwaysdata.com/ permissions_delete endpoint which is intended for deleting sub-accounts' generated data or permissions. However due to unsecure design, it can also be used to remove critical permissions or access controls of the owner account, rendering the account useless.

Proof-of-Concept

1. Visit this URL: https://admin.alwaysdata.com/permissions/<owner-id>/delete/ (Replace owner-id with the the id of main account, that is, the one with 'impossible deletion')

2. This renders the account useless. But permissions can still be reinstated using the following request

POST /permissions/<account-id>/ HTTP/2

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.

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

I am reporting a security vulnerability on the website https://www.alwaysdata.com/en/ The website is affected by prototype pollution due to the usage of an outdated jQuery version.

Description:
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: https://www.alwaysdata.com/en/ 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

Image:
https://ibb.co/VxyNw4z

Impact:
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:
https://hackerone.com/reports/380873 https://hackerone.com/reports/454365 The vulnerability has been verified on jQuery version 1.12.4, and it is likely to affect older versions.

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

Bypassing Two-Factor Authentication via Account Deactivation

Hello Team,

I hope you are doing well. I found a serious issue in https://admin.alwaysdata.com which Bypassing Two-Factor Authentication via Account Deactivation.

The vulnerability arises from a logical flaw in the account recovery and 2FA enforcement processes. Specifically, after deactivating an account, users can takeover and log in without being prompted for 2FA. The 2FA mechanism, which is designed to provide an additional layer of security, is effectively bypassed.

Steps To Reproduce

Go to https://admin.alwaysdata.com and make signup example@gmail.com

Then, go to admin detail section add some details first name, last name etc and activate 2fa.

After, activating 2fa submit and save the details.

After, saving the details click on Delete this profile button on right top side and submit the message what you want.

Your account is deleted without asking password confirmation and 2fa is also deactivated and attacker can easily takeover the account.

Note: This is possible only when user is forgot to login off the account at cafe or something else pc and recreate a account with this email address and reconfigure a 2fa to takeover the account.

Regard,

Waleed Anwar

Description: There is clickjacking vulnerability at https://admin.alwaysdata.com/admin/details/ endpoint. And, for deleting a profile, we just need two clicks.

Steps to reproduce:
1) Open your browser and search for https://admin.alwaysdata.com/admin/details/ 2) create an html file that overlays delete this profile icon and then the submit button.

Impact: Admin's account can be deleted in two clicks.

*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

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.

Vulnerable URL's: https://files.alwaysdata.com/ https://files.alwaysdata.com/migrations/ https://files.alwaysdata.com/migrations/software-2017/ https://files.alwaysdata.com/migrations/software-2020/

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.

Summary: When uploading images in ticket option, the EXIF metadata is not removed or changed in any way.
Description: When answering in the ticket, you can upload a file, and if you upload an image with EXIF metadata on it, it isn't stripped. This can lead to disclosure of location where photo was taken or other personal information by the photo uploader if their group is public, as anyone can download the logo and check the metadata.
Steps To Reproduce:
1) Create a ticket.
2) Upload an image with exif metadata.
3) Now, download the same image and check the metadata.

Hi,
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:-
https://upload.alwaysdata.com/.git/ (403 forbidden)
bypass
https://upload.alwaysdata.com/.git/config https://upload.alwaysdata.com/.git/logs/HEAD

https://security.alwaysdata.com/.git/ (403 forbidden)
bypass
https://security.alwaysdata.com/.git/config https://security.alwaysdata.com/.git/logs/HEAD

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)
Thanks

i found this detial in one of the git file on https://security.alwaysdata.com/.git/config

contact me on my email bhavishthakral123@gmail.com

Description

I discovered that cAdvisor, a container monitoring and management tool, is exposed to the public internet. Using OSINT techniques, this endpoint was discovered on one of the company servers. This information disclosure could potentially be used by attackers for various malicious purposes, such as mapping vulnerable targets or launching further attacks.

Proof-of-Concept

To demonstrate this issue, we can access the cAdvisor web interface via the URLs;
http://185.31.41.177:8000/containers/ http://185.31.41.177:8000/metrics/ http://185.31.41.177:8000/api/v1.0/machine http://185.31.41.177:8000/containers/user.slice http://185.31.41.177:8000/containers/system.slice

Browse through the URIs for more information on processes running, users involved, resource usage, container names e.t.c.

Mitigation

Restrict access to cAdvisor. Limit access to the cAdvisor interface to trusted users or networks only.

Vulnerability Detail

PHPpgAdmin setup page is accessible over the internet in which it's possible for the user setup the servers with required details.

Vulnerable Endpoints

https://phppgadmin.alwaysdata.com/phppgadmin/redirect.php?subject=root You can add a server via this endpoint
https://phppgadmin.alwaysdata.com/phppgadmin/redirect.php?subject=server&server=&

Impact Its possible for an attacker to configure the servers without information of the application adminstrator.

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.

Hello support teams,
I hope this email finds you well. I am Devansh . I am a security researcher and I found a vulnerability in your website.

bug name : Lack of password confirmation on account deletion

Description: the user account can be deleted without confirming user password or re authentication.
The removal of an account is one of the sensitive parts of any application that needs to be protected, therefore removing an account should validate the authenticity of the legitimate user.

steps to reproduce:

1. Go to account settings and click on delete account.

2. There will be a next page where I click on delete my account now option.

3. You will see the message of account has been deleted and get logged out

Remediation:
System must confirm authentic user before performing such task. A link can be sent to the user email id that can be used for delete operation. Otherwise user password should be provided to the application to confirm the entity identity.

It seems to be of very low impact,but consider a situation when a user forgets to logout from his account or someone gets access to his phone and deletes the account. This situation is more severe than account takeover as there is no way to get an account again. All the save information and data including previous record, card information etc can be deleted.

Thanks and regards

- GET-based CSRF vulnerability allows unauthorized account deletion

Steps to Reproduce:

1. Login to the application
2. Trick the user into clicking a malicious link to delete their account: https://admin.alwaysdata.com/admin/details/1/delete 3. User click submit
4. Observe the account being deleted without password confirmation

Recommended Fix:

1. Implement password confirmation requirement for delete account functionality
2. Implement CSRF protection for delete account functionality
3. Validate requests to prevent unauthorized account deletion

Conclusion:

This vulnerability poses a critical risk to user accounts and data. Implementing password confirmation and CSRF protection for delete account functionality will prevent unauthorized account deletion and ensure the security and integrity of user accounts.

### Summary
The website does not verify email addresses during the account creation process, which can lead to various security issues such as spam, abuse, and account recovery problems.

### Steps to Reproduce
1. Go to the account creation page.https://www.alwaysdata.com/en/register/ 2. Enter any email address and complete the registration process.
3. Notice that no email verification step is required.

### Impact
- Spam and Abuse: Unverified accounts can be used to flood the system with spam or perform malicious activities.
- User Impersonation: An attacker can use someone else's email address, leading to possible impersonation issues.
- Account Recovery Problems: Users might face difficulties in recovering their accounts if email addresses are not verified.

### Recommendation
Implement email verification as a mandatory step in the account creation process to ensure that the email addresses are valid and belong to the users registering them.

Description:

The website lacks proper email verification.During the user registration process,it only sending a greeting email upon registration. The absence of email verification could lead to create unverified accounts and host content with any email address, potentially poses a serious security risk.

Impact :

The absence of email verification poses a significant security risk, allowing the potential use of any email address for registration on a hosting site without proper authentication. This could lead to the creation of accounts under false identities, enabling malicious actors to host illegal content anonymously.

The free hosting service, which doesn't require valid details, may be exploited for unauthorized activities, emphasizing the need for robust email verification procedures to ensure account legitimacy and prevent abuse like.

Spam distribution

Phishing campaigns

Distribution of illegal or harmful content
