Rules

What the policy asks of you, and the bug types it won't reward, quoted from Braintree's policy. "We" in these lines means the program, not this site.

While testing

  • Do not cause any damage or disruption to our systems or services.
  • Do not modify any files or data, including permissions, and do not intentionally view or access any data beyond what is needed to prove the vulnerability.
  • Provide your IP address in the bug report (kept private, used only for testing activity review)
  • DoS proof-of-concept (PoC) testing is only permitted against applications where a sandbox environment is available.
  • Under no circumstances are researchers permitted to perform any denial-of-service (DoS) tests or attacks against any of PayPal's production systems
  • No Automated Scanning: Automated tools or scripts designed to overload our infrastructure, or services are not permitted for use in testing.
  • Once your report is closed, securely delete any inadvertently accessed data.
  • Uploading files that allow arbitrary commands (i.e. a webshell)
  • Creating and maintaining a persistent connection to the server

Not accepted

  • Any physical attacks against PayPal property or data centers
  • Username enumeration on customer facing systems
  • Scanner output or scanner-generated reports, including any automated or active exploit tool.
  • Man-in-the-Middle attacks.
  • Vulnerabilities involving stolen employee/consumer/merchant credentials or physical access to a device.
  • Social engineering attacks
  • Open redirection
  • Host header injections without a specific, demonstrable impact.
  • Vulnerabilities found through DDoS or spam attacks.
  • Self-XSS, which includes any payload entered by the victim.
  • Login/logout CSRF
  • Content spoofing without embedding an external link or JavaScript.
  • Issues related to SSL certificates.
  • DNS configuration issues
  • Server configuration issues (e.g. open ports, TLS versions, etc.)
  • Vulnerabilities only affecting users of outdated, unpatched, or unsupported browsers and platforms
  • Information disclosure of public or non-protected information
  • Exposed credentials that are either no longer valid, or do not pose a risk to an in-scope asset.
  • Vulnerabilities on third party libraries without showing specific impact to the target application
  • Reports that involve secondary business accounts, and the impact is limited solely to the parent account.
  • Denial of Service
  • Vulnerabilities requiring a rooted, jailbroken, or otherwise modified device
  • Exposure of non-sensitive data on the device
  • Vulnerabilities requiring extensive user interaction
