By participating in this program, you agree to:

  • Respect the Community Code of Conduct
  • Respect the Intigriti Terms and Conditions
  • Respect the scope of the program
  • Not discuss or disclose vulnerability information without prior written consent (including PoC's on YouTube and Vimeo)

Important guidelines

Provide a proof-of-concept(POC) for the vulnerability and explain the information security impact to the best of your knowledge.

Since we use various automatic scanners for vulnerability management and gain those results as part of regular business, we cannot accept any submissions found by using automatic scanners.

Create your own account for testing purposes and use your @intigriti.me email. Do not attempt to gain access to another user’s account or compromise any confidential information of Atolls.

Avoid privacy violations, confidentiality breaches, degradation of user experience, disruption to production systems, and destruction or manipulation of data. Do not cause harm to Atolls employees, customers and users.

Only use exploits to the extent necessary to confirm a vulnerability’s presence. Do not use any exploit to compromise or exfiltrate data, establish command line access and/or persistence, or to pivot to other systems.

Once you’ve established that a vulnerability exists or you encountered any sensitive data (including personally identifiable information, financial information, or proprietary information or trade secrets of any party), you must stop your test, report here, and do not disclose this data to anyone else. Do not try to use the existence of a vulnerability to access, store and use the data. Do not share your findings and investigations knowledge with anyone except Atolls.

Do not attempt to make illegal demands to obtain anything except what this program offers.

Atolls reserves the right to change the terms of this program without giving any reason and/or notification to you. Please check for any updates before submitting a new finding.

Introduction

We are happy to announce our Vulnerability disclosure program! We've done our best to clean up our known issues and now would like to request your help to spot the ones we missed!

You're welcome to subscribe to our program to receive updates.

Out of scope

Domains

Any domain that is not listed in the Domains section, is out of scope for this program

Please consider below application related vulnerabilities and/or methods out of scope for this program

  • Pre-Auth Account takeover/OAuth squatting
  • Self-XSS that can't be used to exploit other users
  • Verbose messages/files/directory listings without disclosing any sensitive information
  • CORS misconfiguration on non-sensitive endpoints
  • Missing cookie flags
  • Missing security headers
  • Cross-site Request Forgery with no or low impact
  • Presence of autocomplete attribute on web forms
  • Reverse tabnabbing
  • Bypassing rate-limits or the non-existence of rate-limits.
  • Best practices violations (password complexity, expiration, re-use, etc.)
  • Clickjacking without proven impact/unrealistic user interaction
  • CSV Injection
  • Sessions not being invalidated (logout, enabling 2FA, etc.)
  • Tokens leaked to third parties
  • Anything related to email spoofing, SPF, DMARC or DKIM
  • Content injection without being able to modify the HTML
  • Username/email enumeration
  • Email bombing
  • HTTP Request smuggling without any proven impact
  • Homograph attacks

  • Not stripping metadata of files
  • Same-site scripting
  • Subdomain takeover without taking over the subdomain
  • Arbitrary file upload without proof of the existence of the uploaded file
  • Blind SSRF without proven business impact (pingbacks aren't sufficient)
  • Disclosed/misconfigured Google Maps API keys
  • Host header injection without proven business impact

General

  • In case that a reported vulnerability was already known to the company from their own tests, it will be flagged as a duplicate
  • Theoretical security issues with no realistic exploit scenario(s) or attack surfaces, or issues that would require complex end user interactions to be exploited
  • Spam, social engineering and physical intrusion
  • DoS/DDoS attacks or brute force attacks
  • Vulnerabilities that only work on software that no longer receive security updates
  • Attacks requiring physical access to a victim's computer/device, man in the middle or compromised user accounts
  • Recently discovered zero-day vulnerabilities found in in-scope assets within 14 days after the public release of a patch or mitigation may be reported, but are usually not eligible for a bounty
  • Reports that state that software is out of date/vulnerable without a proof-of-concept

Mobile

  • Shared links leaked through the system clipboard
  • Any URIs leaked because a malicious app has permission to view URIs opened
  • The absence of certificate pinning
  • Sensitive data in URLs/request bodies when protected by TLS
  • Lack of obfuscation
  • Path disclosure in the binary
  • Lack of jailbreak & root detection
  • Crashes due to malformed URL Schemes
  • Lack of binary protection (anti-debugging) controls, mobile SSL pinning
  • Snapshot/Pasteboard leakage
  • Runtime hacking exploits (exploits only possible in a jailbroken environment)
  • API key leakage used for insensitive activities/actions
Severity assessment

This program follows Intigriti's triage standards based on the proof of concept.
