51 | Closed | Multiple Free Public Cloud accounts obtained by a singl ... | d_sharad |
Task Description
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: https://admin.alwaysdata.com/admin/account/ 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.
Impact
By exploiting account ownership transfers, a user can essentially obtain unlimited free storage, potentially leading to loss for alwaysdata
Recommendation
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.

49 | Closed | Vulnerability Report: Lack of Rate Limiting on Password ... | anshumanbaghel |
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 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

35 | Closed | Git Folder Forbidden Bypass | roxy |
Task Description
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

Task Description
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

27 | Closed | Text Injection | Cypher |
Task Description
Description:
Content spoofing, also referred to as content injection, “arbitrary text injection” or virtual defacement, is an attack targeting a user made possible by an injection vulnerability in a web application. When an application does not properly handle user-supplied data, an attacker can supply content to a web application, typically via a parameter value, that is reflected back to the user. This presents the user with a modified page under the context of the trusted domain. This attack is typically used as, or in conjunction with, social engineering because the attack is exploiting a code-based vulnerability and a user’s trust.
Impact:
An attacker can use text injection vulnerability to present a customized message on the application that can phish users into believing that the message is legitimate. The intent is typical to tick victims, although sometimes the actual purpose may be to simply misrepresent the organization or an individual.
Steps to Reproduce:
1: Navigate to given URL: https://admin.alwaysdata.com/ 2: At the end of the URL enter /hacker 3: Now on the page you will see hacker is reflecting on page.

Task Description
Title: Security Report: Public Exposure of Sensitive Information
Introduction: The purpose of this report is to highlight a critical security issue involving the public exposure of sensitive information on the website security.alwaysdata.com. The exposed data includes details about supervisors, the number of reports they have sorted, and some reports that remain unprocessed and may contain sensitive information and unpatched vulnerabilities.
Exposure of Supervisor Information: The website security.alwaysdata.com hosts a page that displays information about all users, including supervisors. The URL format for accessing supervisor information is https://security.alwaysdata.com/user/1. By manipulating the numeric value in the URL, it is evident that any user can access information about all users and supervisors on the site. This unrestricted access poses a significant security risk as it allows unauthorized individuals to view sensitive user data, potentially compromising the privacy and security of the users and the platform as a whole.
Unsecured Reports: Furthermore, the website contains reports that are in an unprocessed state and have not been closed. These reports are accessible to the public through the URL format https://security.alwaysdata.com/task/23?dev=1. The presence of such reports in an open state poses a severe security threat as they may contain sensitive information that should not be shared with regular users. Additionally, these reports may reveal unpatched vulnerabilities in the platform, further increasing the risk of exploitation by malicious actors.
Recommendations: 1. Immediate Restriction of Access: It is imperative to implement access controls to restrict public access to supervisor information and unprocessed reports. Access should be limited to authorized personnel with appropriate privileges.
2. Review and Remediation: All unprocessed reports should be reviewed to identify and address any sensitive information or vulnerabilities they may contain. Once remediated, these reports should be appropriately secured and closed.
3. Security Awareness Training: Conduct security awareness training for all personnel involved in managing and maintaining the website. Emphasize the importance of safeguarding sensitive data and the potential consequences of data exposure.
4. Regular Security Audits: Implement regular security audits to identify and address any potential security loopholes, including unauthorized access to sensitive information and unsecured reports.
Conclusion: The public exposure of supervisor information and unsecured reports on security.alwaysdata.com poses a significant security risk, potentially compromising user privacy and platform integrity. Immediate action is necessary to address these vulnerabilities and ensure the confidentiality and security of user data. Failure to mitigate these risks could lead to severe repercussions for the organization and its users.

Task Description
Security Report:Broken Access Control (BAC) refers to a security vulnerability where users are able to access or manipulate resources that they are not authorized to
Introduction: Broken Access Control (BAC) refers to a security vulnerability where users are able to access or manipulate resources that they are not authorized to. In this report, we will discuss an instance of BAC where a user is able to delete a technical support ticket to which they have been invited, even though they do not have the necessary permissions to do so.
The user who is added to the ticket does not have the permission to delete the ticket, he is not the one who created it.
Command used to delete:https://admin.alwaysdata.com/support/"Ticket_Number"/delete/
Steps to reproduce the bug:
1- Open a technical support ticket 2- Add a user with you in the ticket 3- Try the delete order I sent you 4- You will notice that the invited user can delete the ticket completely and this is not his prerogative
Impact: The impact of this vulnerability is significant as it compromises the integrity and confidentiality of the technical support system. Unauthorized deletion of tickets can lead to loss of important information, disruption of support services, and potential security breaches if sensitive information is contained within the tickets.

Vulnerability Type: Transmission of Credentials in Plain Text Website: https://www.alwaysdata.com/ Description: During testing of the login process on the Alwaysdata.com 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 Alwaysdata.com 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.
Impact:
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.
Severity:
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 Alwaysdata.com 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 Alwaysdata.com platform.

19 | Closed | User Enumeration Through Forgot Password Vulnerability | basil |
Task Description
The application's "Forgot Password" feature allows user enumeration. This is because the application responds with a different message depending on whether the submitted email address is registered or not. (https://admin.alwaysdata.com/password/lost/)
steps to Reproduce:
Access the "Forgot Password" page. Enter a random, non-registered email address. Submit the request. Observe the response message:
the message states "There is no account with this email address," which means that user enumeration is possible.
An attacker could exploit this vulnerability to:
Gather a list of valid user email addresses. Launch targeted phishing attacks. Use the information to attempt password guessing or brute force attacks
Remediation: Implement Generic Response: The application should provide the same response message regardless of whether the email address is registered or not. This prevents attackers from differentiating between valid and invalid accounts.
Additional Notes:
i am aware that this bug is not eligible for a bounty but wanted to bring it to the team's attention.

I'm writing to report a critical Reflected Cross-Site Scripting (XSS) vulnerability discovered in your [admin.alwaysdata.com] application. This vulnerability allows attackers to inject malicious JavaScript into the application, potentially compromising user accounts and sensitive data.
PoC: By sending a specially crafted request containing the payload redhet"'><script>prompt(document.domain)</script> through the add_participants parameter in the support ticket creation form, we can trigger the XSS vulnerability and execute arbitrary JavaScript in the victim's browser.
Summary:
A reflected XSS vulnerability has been identified in the "add_participants" parameter of the support ticket creation form on admin.alwaysdata.com. This vulnerability allows attackers to inject malicious JavaScript code that will be executed in the victim's browser when they view a vulnerable page.
Vulnerability Details:
Type: Reflected XSS (OWASP A4)
Exploit: Injecting malicious JavaScript through a vulnerable request parameter
Vulnerable URL: https://admin.alwaysdata.com/support/add/
Vulnerable Request: POST /support/add/
Vulnerable Endpoints: The add_participants parameter in the support ticket creation form
Payload: redhet"'><script>prompt(document.domain)</script>
This parameter is used to add participants to a support ticket, but it is not properly sanitized, allowing attackers to inject arbitrary code that will be executed in the browser of any user who views the vulnerable ticket.
## Impact Assessment
1. Impact one: Information Disclosure: The attacker can steal sensitive user information, such as cookies or session IDs, by executing malicious JavaScript within the victim's browser.
2. Impact two: Account Takeover: The attacker could potentially hijack user accounts by tricking them into executing malicious code that grants unauthorized access.
3. Impact three: Defacement: The attacker could manipulate the content displayed on the application by injecting malicious JavaScript that alters the user interface.
## Recommendations
1. Step one: Immediately sanitize all user input: Implement strict input validation and sanitization procedures to prevent the injection of malicious code. This includes escaping special characters and enforcing a Content Security Policy (CSP).
2. Step Two: Patch vulnerable software: Update all relevant software to the latest versions to address known vulnerabilities.
3. Step three: Consider additional security measures: Implement a web application firewall (WAF) to further protect against XSS attacks.
4. Step four:Regularly scan for vulnerabilities: Conduct regular penetration testing and vulnerability scans to identify and address potential security issues.
Impact:
Execution of arbitrary JavaScript code in the victim's browser Potential for session hijacking, credential theft, or other attacks
## Steps to Reproduce
1. Step one: Access the support ticket creation form at https://admin.alwaysdata.com/support/add/
2. Step two: Enter the following payload in the "add_participants" field: redhet"'><script>prompt(document.domain)</script>
3. Step three: Submit the form.
4. Final step: Observe that the JavaScript code is executed, displaying a prompt with the domain name. (cookies)
