Rules of engagement

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)

Our promise to you

• We are happy to respond to any questions, please use the button in the right top corner for this.
• We respect the safe harbour clause that you can find below

Your promise to us

• You will always clearly identify yourself as researcher, with your Intigriti username and/or intigriti.me email address (bounty can be denied if you don't).
• Provide detailed but to-the point reproduction steps
• Include a clear attack scenario. How will this affect us exactly?
• Remember: quality over quantity!
• Please do not discuss or post vulnerabilities without our consent (including PoC's on YouTube and Vimeo)
• Please do not use automatic scanners. Be creative and do it yourself! We cannot accept any submissions found by using automatic scanners. Scanners also won't improve your skills, and can cause a high server load (we'd like to put our time in thanking researchers rather than blocking their IP's 😉)
• Be wary when testing platforms that can impact real users (e.g. job listings) or require manual clean-up in the back-end.

In scope

We are happy to announce our responsible disclosure program! We've done our best to clean most of our known issues and now would like to request your help to spot the once we missed! We are specifically looking for

• leaking of personal data
• horizontal / vertical privilege escalation
• SQLi
• ...

For CPDoS on highly cached content (i.e. where successful responses are cached for a long time), we may evaluate the submission with CVSS Attack Complexity "High".

Out of scope

Redirects on unused domains

We have a substantial amount of parked domains due to acquisitions of other companies. Some of them redirect to other domains which can still be registered. These types of link hijacking our out-of-scope for this program.

Highlighted

• Domains that are not 100% owned by DPG media
• Open redirects in privacy consent endpoints (eg /privacygate-confirm, /privacy-wall etc)
• Paywall can be bypassed
• User password leaks, not originating from a vulnerability on our side, can be reported but will not be rewarded with a bounty.

Application

• API key disclosure without proven business impact
• Wordpress usernames disclosure
• Pre-Auth Account takeover/OAuth squatting
• Self-XSS that cannot 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
• XMLRPC enabled
• Banner grabbing/Version disclosure
• 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 are not 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

All our rewards are impact based, therefore we kindly ask you to carefully evaluate a vulnerability's impact when picking a severity rating. To give you an idea of what kind of bugs belong in a certain severity rating we've put some examples below. Note that depending on the impact a bug can sometimes be given a higher/lower severity rating.

Exceptional

• A remote code execution vulnerability on the production server
• Full database access (incl. update/delete)

Critical

• A SQL injection vulnerability
• Access to all customer personal data or access to a targeted user
• A numeric IDOR that allows mass write/read actions on critical features
• Path traversal leading to the disclosure of local files

High

• Access to random users' data (sensitive PII)
• A stored XSS vulnerability (excluding unexploitable self-XSS)
• Vertical authentication bypass

Medium

• A DOM XSS vulnerability
• Reflected XSS
• An IDOR leading to the disclosure of non-critical data
• A CSRF with a significant impact
• Lateral authentication bypass

Low

• A reflected XSS vulnerability that requires significant user interaction
• A CSRF vulnerability in a non-critical feature
• Open redirect

IDORs with UUID identifiers

IDORs where the identifier is a UUID will be evaluated as a low risk vulnerability. Unless the submission provides a realistic scenario of enumeration by for example by combining with a method to leak/list valid UUIDs or if the UUIDs are not randomly generated (e.g. UUIDv1) and/or can be guessed.

Cool-down period for zero-days

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. We may however decide to offer a bonus at our own discretion!

FAQ

Where can we get credentials for the app?

We currently don’t offer any credentials to test user roles.
