Responsible Disclosure Policy

Introduction

Paymatrix takes the security of our systems and its data very seriously. We are continuously striving to maintain and ensure that our environment is safe and secure for everyone to use. If you’ve discovered any security vulnerabilities associated with any of our Paymatrix services, we do appreciate your help in disclosing it to us in a responsible manner.


Paymatrix will engage with you as external security researchers (the Researcher) when vulnerabilities are reported to us in accordance with this Responsible Disclosure Policy.


If a Researcher follows the rules set out in this Responsible Disclosure Policy when reporting a security vulnerability to us, unless prescribed otherwise by law or the payment scheme rules, we commit to:

  • Promptly acknowledging receipt of your vulnerability report and work with the researcher to understand and attempt to resolve the issue quickly;
  • Validating, responding and fixing such vulnerability in accordance with our commitment to security and privacy. We will notify you when the issue is fixed
  • Unless prescribed by law otherwise, not pursue or take legal action against you or the person who reported such security vulnerabilities;
  • Not suspend or terminate access to our service/services if you are a merchant. If you are an agent, not suspend or terminate merchants access to our services to which the agent represents;
  • Publicly acknowledge and recognise your responsible disclosure in our Hall of Fame page.

Scope of this Policy

Any of the Paymatrix services iOS, Android or Web apps, which process, store, transfer or use in one way or personal or sensitive personal information, such as card data and authentication data.

  • Able to bypass payment flow
  • Price manipulation with a successful transaction (transaction id required)
  • SQL Injections
  • Remote Code Execution (RCE) vulnerabilities
  • Shell Upload vulnerabilities (only upload basic backend script that just prints some string, preferably try printing the hostname of the server and stop there ! **YES STOP THERE** ! )
  • Authentication and Authorization vulnerabilities including horizontal and vertical escalation. (Use 2 different test accounts created by you)
  • Domain take-over vulnerabilities
  • Stored XSS
  • Bulk user sensitive information leak

Testing

A Researcher can test only against a merchant account if they are an account owner or an agent authorized by the account owner to conduct such testing. As a Researcher, in no event are you permitted to access, download or modify data residing in any other account or that does not belong to you or attempt to do any such activities. In the interest of the safety of our merchants, users, employees, the Internet at large and you as a Researcher, the following test types are expressly excluded from scope and testing: any findings from physical testing (office access, tailgating, open doors) or DOS or DDOS vulnerabilities. A responsible disclosure also does not include identifying any spelling mistakes, or any UI and UX bugs.

Rules

We require that all Researchers must:

  • Make every effort to avoid privacy violations, degradation of user or merchant experience, disruption to production systems, and destruction of data during security testing.
  • Not attempt to gain access to any other persons account, data or personal information.
  • Use their real email address to signup and report any vulnerability information to us.
  • Keep information about any vulnerabilities you’ve discovered confidential between yourself and Paymatrix. Paymatrix will take a reasonable time to remedy such vulnerability (approximately 1 month as a minimum but this is dependent on the nature of the security vulnerability and regulatory compliance by Paymatrix). The Researcher shall not publicly disclose the bug or vulnerability on any online or physical platform before it is fixed and prior written approval to publicly disclose from Paymatrix.
  • Not perform any attack that could harm the reliability, integrity and capacity of our Services. DDoS/spam attacks are STRICTLY not allowed
  • Not use scanners or automated tools to find vulnerabilities (noisy and we may automatically suspend your account and ban your IP address)
  • As a Researcher, you represent and warrant that you have the right, title and interest to disclose any vulnerability found and to submit any information, including documents, codes, among others, in connection therewith. Once you inform a vulnerability, you grant Paymatrix, its subsidiaries and affiliates an irrevocable, worldwide, royalty-free, transferable, sublicensable right to use in any way Paymatrix deems appropriate for any purpose, such as: reproduction, modification, distribution, adaptation among other uses, the information related with the vulnerabilities. Further, you hereby waive all other claims of any nature, including express contract, implied-in-fact contract, or quasi-contract, arising out of any disclosure accepted by Paymatrix.


Remember that you must never attempt non-technical attacks such as social engineering, phishing, or physical attacks against our employees, users, or infrastructure. Please include the following information with your report:

  • Detailed description of the steps required to help us reproduce the vulnerability (POC scripts, screenshots, and compressed screen captures are all helpful to us)
