Responsible Disclosure Policy

To encourage responsible disclosures, Nkuyege commits that, if we conclude, in our sole discretion, that a disclosure respects and meets all the guidelines of these Program Terms and the Nkuyege Agreements, Nkuyege will not bring a private action against you or refer a matter for public inquiry.

Eligibility Requirements

To participate in the Bug Bounty Program, you must have a Nkuyege account in good standing in order to register for the Bug Bounty Program and be eligible to receive Bounty Payments (described further below). Alternatively, if you do not have a Nkuyege account, you may elect to submit reports via email, but you won’t be eligible for a Bounty Payment. If you do not currently have a Nkuyege account, you can sign up for one here.

To be eligible for the Bug Bounty Program, you must not:

• Be a resident of, or make your Submission from, a country against which the United States has issued export sanctions or other trade restrictions (e.g., Cuba, Iran, North Korea, Sudan and Syria);

If Nkuyege discovers that you do not meet any of the criteria above, Nkuyege will remove you from the Bug Bounty Program and disqualify you from receiving any bounty payments. Any submissions you make to Nkuyege, whether via your Bug Bounty Program account or via email shall be considered “Submission(s)” for purposes of these Program Terms.

Bug Submission Requirements and Guidelines

In researching vulnerabilities on Nkuyege’s sites, you may not engage in testing that (i) results in a degradation of Nkuyege systems, (ii) results in you, or any third party, accessing, storing, sharing or destroying Nkuyege or customer data, or (iii) may impact Nkuyege customers, such as denial of service, social engineering or spam.

You may not publicly disclose your findings or the contents of your Submission in any way without Nkuyege’s prior written approval.

Failure to follow these guidelines will result in immediate disqualification from the Bug Bounty Program and ineligibility for receiving any bounty payments.

For all submissions, please include:

• Full description of the vulnerability being reported including the exploitability and impact
• Document all steps required to reproduce the exploit of the vulnerability
• Provide all:
  • URL(s)/application(s) affected in the submission (even if you provided us a code snippetvideo as well)
  • IPs that were used while testing
  • Always include the user ID that is used for the POC
  • Always include all of the files that you attempted to uploaded
  • Provide the complete PoC for your submission (e.g. For RCE’s do not change files, upload only “hello world” test files, etc.)
  • Please save all the attack logs and attach them to the submission.
  • Remote Code Execution (RCE) Submission Guidelines
• Failure to include any of the above items may delay or jeopardize the bounty payment.

Ownership of Submissions

As between Nkuyege and you, as a condition of participation in the Nkuyege Bug Bounty Program, you hereby grant Nkuyege, its subsidiaries, affiliates and customers a perpetual, irrevocable, worldwide, royalty-free, transferrable, sublicensable (through multiple tiers) and non-exclusive license to use, reproduce, adapt, modify, publish, distribute, publicly perform, create derivative work from, make, use, sell, offer for sale and import the Submission, as well as any materials submitted to Nkuyege in connection therewith, for any purpose.

You hereby represent and warrant that the Submission is original to you and you own all right, title and interest in and to the Submission. 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 of the Submission to Nkuyege. In no event shall Nkuyege be precluded from discussing, reviewing, developing for itself, having developed, or developing for third parties, materials which are competitive with those set forth in the Submission irrespective of their similarity to the information in the Submission, so long as Nkuyege complies with the terms of participation stated herein.

Eligible Domains Policy

The following domains are included for the Nkuyege family of companies:

• https://nkuyege.com
• https://nkuyege.com

Out-of-Scope Vulnerabilities

Certain vulnerabilities are considered out-of-scope for the Bug Bounty Program. Those out-of-scope vulnerabilities include, but are not limited to:

• Vulnerabilities dependent upon social engineering techniques (e.g. shoulder attack, stealing devices, phishing, fraud, stolen credentials)
• Host Header
• Denial of service (DOS)
• Self-XSS (User defined payload)
• Login/logout CSRF
• Content spoofing without embedded links/HTML
• Vulnerabilities which require a jailbroken mobile device
• Infrastructure vulnerabilities, including:
  • Certificates/TLS/SSL related issues
  • DNS issues (i.e. mx records, SPF records, etc.)
  • Server configuration issues (i.e., open ports, TLS, etc.)
• Most vulnerabilities within our sandbox, lab, or staging environments.
• Outdated web browsers: vulnerabilities contingent upon outdated or unpatched browsers will not be honored, including Internet Explorer versions prior to version 8
• Vulnerabilities involving active content such as web browser add-ons
• Information disclosure of public or information that does not present risk to our Nkuyege customers or Nkuyege (i.e. web server type disclosure)
• Most Connected Commerce Cloud (C3) submissions are out of scope
  • We will review C3 submissions and depending upon the level of risk we will determine if this submission will be eligible

Bounty Payments

You may be eligible to receive a monetary reward, or “bounty,” if: (i) you are the first person to submit a site or product vulnerability; (ii) that vulnerability is determined to by a valid security issue by Nkuyege’s security team; and (iii) you have complied with all Program Terms.

Bounty payments, if any, will be determined by Nkuyege, in Nkuyege’s sole discretion. In no event shall Nkuyege be obligated to pay you a bounty for any Submission. All bounty payments shall be considered gratuitous.

In the event Nkuyege elects to pay you a bounty, Nkuyege may make a partial payment when the vulnerability is first verified by Nkuyege and then an additional payment once the vulnerability has been fixed. The format and timing of all bounty payments shall be determined in Nkuyege’s sole discretion.

All bounty payments must be made to a Nkuyege Account in good standing. If you do not have a Nkuyege Account in good standing at the time of payment, you will not be eligible to receive a bounty (except in extraordinary circumstances agreed to by Nkuyege via email from the Bug Bounty Program team).

All bounty payments will be made in United States dollars (USD). You will be responsible for any tax implications related to bounty payments you receive, as determined by the laws of your jurisdiction of residence or citizenship.

Nkuyege will determine all bounty payout based on the risk and impact of the vulnerability. The minimum bounty amount for a validated bug submission is $1 USD and the maximum bounty for a validated bug submission is $100 USD.

Nkuyege Bug Bounty Team retains the right to determine if the bug submitted to the Bug Bounty Program is eligible. All determinations as to the amount of a bounty made by the Nkuyege Bug Bounty Team are final.

Additional Terms

+Payout ranges are based on the classification and sensitivity of the data impacted, ease of exploit and overall risk to Nkuyege customers, Nkuyege brand and determined to be a valid security issue by Nkuyege’s security engineers. Common sensitive data elements include customer social security number, credit card number, card verification code, bank account number, login credentials and passwords. Nkuyege may pay beyond the range at times when bugs are found to have significant risk.

#Please note that Clickjacking and CSRF vulnerabilities are only reviewed for sites and pages where the ease of exploit and risk to Nkuyege is significant. Also, please note that, while "Logout CSRF" is a well-acknowledged issue, there are other techniques (like "cookie forcing" and "cookie bombardment") that can make it futile to defend against this attack. Also, Nkuyege web sessions are relatively short lived and hence, the Nkuyege will not consider reports of the ability to log out users from Nkuyege as qualifying for a bounty.

Wall of Fame

In an effort to provide recognition to research partners, from time to time Nkuyege may feature persons who have made significant contributions. Where selected, and upon mutual written agreement regarding acceptable attribution (email being sufficient), you hereby grant Nkuyege the right to display the display name and/or attribution information on Nkuyege’s Wall of Fame and such other media as Nkuyege desires to publish. Either party may elect to no longer participate or publish contribution information. Nkuyege has the right to remove contribution information of any person that at any time does not comply with the Program Terms or the terms of User Agreement.

Termination

In the event (i) you breach any of these Program Terms or the terms and conditions of the Nkuyege Agreements; or (ii) Nkuyege determines, in its sole discretion that your continued participation in the Bug Bounty Program could adversely impact Nkuyege (including, but not limited to, presenting any threat to Nkuyege’s systems, security, finances and/or reputation) Nkuyege may immediately terminate your participation in the Bug Bounty Program and disqualify you from receiving any bounty payments. Please see our recommendations on the proper procedures for testing our applications.

Confidentiality

Any information you receive or collect about Nkuyege or any Nkuyege user through the Bug Bounty Program (“Confidential Information”) must be kept confidential and only used in connection with the Bug Bounty Program. You may not use, disclose or distribute any such Confidential Information, including, but not limited to, any information regarding your Submission and information you obtain when researching the Nkuyege sites, without Nkuyege’s prior written consent..

Indemnification

In addition to any indemnification obligations you may have under the Nkuyege Agreements, you agree to defend, indemnify and hold Nkuyege, its subsidiaries, affiliates and the officers, directors, agents, joint ventures, employees and suppliers of Nkuyege, its subsidiaries, or our affiliates, harmless from any claim or demand (including attorneys’ fees) made or incurred by any third party due to or arising out of your Submissions, your breach of these Program Terms and/or your improper use of the Bug Bounty Program.

Changes to Program Terms

The Bug Bounty Program, including its policies, is subject to change or cancellation by Nkuyege at any time, without notice. As such, Nkuyege may amend these Program Terms and/or its policies at any time by posting a revised version on our website. By continuing to participate in the Bug Bounty Program after Nkuyege posts any such changes, you accept the Program Terms, as modified.

Frequently Asked Questions

What constitutes a valid bug submission?

The bug must be in scope of our program sites, within a category of vulnerabilities that are within program scope, and found to be a valid security issue by our security engineers. Your submission must be the first of its kind as duplicate submissions will be invalid.

What is considered within the payout range of bounties?

Payout ranges are based on the classification of the data impacted, ease of exploit and overall risk to Nkuyege customers and the Nkuyege brand. We may pay beyond the range at times when bugs are found to have significant risk. The amount of all bounty payments, if any, will be determined by Nkuyege, in Nkuyege’s sole discretion.

Is my bug fixed? Where is my payout?

If you have reviewed your bug and believe it is fixed, please contact us and let us know. We will review your bug and verify if it is fixed. When your bug is fixed, your final bounty will be submitted and you will receive an email notification.

Why was my bug submission found to be a duplicate?

If the bug you have reported was already submitted by another researcher and found to be valid, we will not be able to honor similar bug submissions following that. We have had great participation from our research community. The growing volume of researchers will many times lead to duplicate bug findings. We must honor the first submission of its type and reject subsequent submissions.

What types of bugs are typically awarded on the high range of bounties?

Besides the category of bug and the risk it presents, the type of information exposed is important when determining the severity. Confidential or restricted customer personal identifiable information (PII) exposed as well as the content sensitivity of the page are factors that can facilitate a higher bounty payout.

What types of bugs are commonly rejected?

Bugs that present negligible to no impact to our customers or company. Common examples include:

• Error messages void of sensitive data
• Web server type disclosure
• Clickjacking on pages without sensitive content, authentication, or state changing actions
• Self-XSS scenarios that would require additional user interaction, including the user manually inputting the XSS payload.
• Most vulnerabilities within our sandbox, lab or staging environments. Domains utilized by customers take precedence

What should I be aware of when testing?

• Please be aware of all program criteria and scope, as well as the Program Terms.
• Do not engage in testing that can impact our customers, like denial of service, social engineering or spam.
• When utilizing personal or test accounts, they are subject to our fraud controls and filters and may act upon irregular activity.
• A proof of concept consisting of detailed steps or screen shots is helpful in facilitation of review and eventual fix.

Will any of my previously filed bugs be lost if I create a new Bug Bounty account using Nkuyege login?

We want to assure you that none of the account history will be lost. You will continue to get notifications to your email for any status changes on previously filed bugs. If you need additional information concerning any open issues filed through the old portal, please contact us with the correct EIBBP number.
