vidaXL Services - Open Bug Bounty Program

vidaXL Services

At vidaXL, we consider the security of our systems a top priority. But no matter how much effort we put into system security, there can still be vulnerabilities present. If you discover a vulnerability, we would like to know about it, so we can take steps to address it as quickly as possible. We would like to ask you to help us better protect our clients and our systems.

Scopes description

For us it is important, that our whole webshops are being checked extensively (like homepage, product listing pages, product detail page, cart page, myaccount pages, login page, checkout page, thank you page, etc. and the different functionalities on them (f.e. loyalty programme, payment service provider, etc).

Please take into account the following rules:

Only use the following 3 EAN's when placing test orders

8718475559313

8718475616184

8718475719380

(f.e. www.vidaxl.xx/e/8718475559313) (in case of violation, no bounty can be awarded). These are product EANs for products you can use to test.

Note: not all EANs are available on all webshops, as assortment can be different per webshop.

Shared codebase disclaimer: All webshops in scope use the same code-base and backend. If a specific issue has already been found in another vidaXL shop the report will be regarded as a duplicate.

Salesforce Assets: For Salesforce assets, the following rules apply: https://help.salesforce.com/articleView?id=000356579&type=1&mode=1

Thank you for browsing our pages and helping protect our shop and our customers!

• Make sure to apply hunting requirements policy (User-Agent, VPN...)

Reports of leaks and exposed credentials

In the context of this program, we do not intend to encourage, accept or reward reports of leaks that are not applicable to our program's scope and identified outside of our program's scope, such as:

• Exposed credentials in/from an out-of-scope asset/source

• Sensitive information exposed in/from an out-of-scope asset/source

Also, in order not to encourage dark and grey economies, in particular the purchase, resale and trade of identifiers or stolen information, as well as all types of dangerous behavior (e.g. social engineering, ...), we will not accept or reward any report based on information whose source is not the result of failure on the part of our organization or one of our employees/service providers.

This excludes, but is not limited to:

• Stolen credentials gathered from unidentified sources

• Exposed credentials that are not applicable on the program's scope

• Exposed GitHub/GitLab (or similar) instance with no direct relation with our program's scope

• Exposed PII on an out-of-scope asset

Policy Table

Important precautions and limitations

As a complement to the Program's rules and testing policy:

• DO NOT alter compromised accounts by creating, deleting or modifying any data

• DO NOT use compromised accounts to search for post-auth vulnerabilities (they won't be eligible anyway)

• DO NOT include Personally Identifiable Information (PII) in your report and please REDACT/OBFUSCATE the PII that is part of your PoC (screenshot, server response, JSON file, etc.) as much as possible.

• In case of exposed credentials or secrets, limit yourself to verifying the credentials validity

• In case of sensitive information leak, DO NOT extract/copy every document or data that is exposed and limit yourself to describe and list what is exposed.
