BUG BOUNTY POLICY

Capitalized terms used in this Bug Bounty Policy and not otherwise defined have the meaning ascribed to such terms in our Master Subscription Agreement __.

Zendesk aims to keep its Service safe for everyone, and data security is of utmost priority. If you are a security researcher and have discovered a security vulnerability in the Service, we appreciate your help in disclosing it to us privately and giving us an opportunity to fix it before publishing technical details.

Zendesk will engage with security researchers when vulnerabilities are reported to us as described here. We will validate, respond, and fix vulnerabilities in support of our commitment to security and privacy. We won’t take legal action against, suspend, or terminate access to the Service of those who discover and report security vulnerabilities responsibly. Zendesk reserves all of its legal rights in the event of any noncompliance.

Reporting

Share the details of any suspected vulnerabilities with the Zendesk Security Team by filing a report. Please do not publicly disclose these details outside of this process without explicit permission. In reporting any suspected vulnerabilities, please include the following information:

  • Vulnerable URL - the endpoint where the vulnerability occurs;
  • Vulnerable Parameter - if applicable, the parameter where the vulnerability occurs;
  • Vulnerability Type - the type of the vulnerability;
  • Steps to Reproduce - step-by-step information on how to reproduce the issue
  • Screenshots or Video - a demonstration of the attack; and
  • Attack Scenario - an example attack scenario may help demonstrate the risk and get your issue resolved faster.

Reports should only reference accounts owned by the researcher. Researchers can sign up for a trial here __. Reports that carry an acceptable risk but demonstrate a valid security-related behavior will be closed as informative. Submissions that don’t present a security risk, are false positives, or are out of scope will be closed as N/A. (Please note that the scope is outlined below.)

Identical reports will be marked as “Duplicate[s]” of the original submission; the original report can be marked as (but not limited) to “Triaged”, “N/A”, or “Informative.”

More information on a proper submission, report states, and acceptable reporting behavior, can be found on linked Hackerone’s articles.

Testing Exclusion

In no event are you permitted to access, download or modify data residing in any other Account, or one that is not registered to you. We will not honor any issues which result from testing our customers. All research must be conducted using your own Zendesk instance which you can sign up for here __.

You are also prohibited from:

  • Attempting to social engineer Zendesk staff.
  • Executing or attempting to execute any Denial of Service attack.
  • Knowingly posting, transmitting, uploading, linking to, sending or storing any Malicious Software.
  • Testing in a manner that would result in the sending of unsolicited or unauthorized junk mail, spam, pyramid schemes or other forms of duplicative or unsolicited messages.
  • Testing third party applications or websites or services that integrate with or link to the Service.

Bounty Ineligible Issues
