Description

SimScale enables engineering teams to access accurate and fast simulation, on their terms, without compromises. We make engineering simulation technically and economically accessible from everywhere, at any time, and at any scale, in the cloud. We deliver instant access to fluid, thermal, and structural simulation to over 300,000 users. With SimScale, engineering simulation has moved from a complex and cost-prohibitive desktop application to an inclusive, agile, cloud-native simulation platform.

In scope

We are happy to announce our first bug bounty program! We've done our best to clean most of our known issues and now would like to request your help to spot the ones we missed!

Focus areas

Beside the classic web application vulnerabilities (XSS, SQLi, RCE, etc.), we are especially interested in vulnerabilities that affect our customer's trust into our platform, such as:

  • Access to private customer data (e.g. projects, CAD files, simulation results)
  • Privilege escalation (both vertical and horizontal)
  • Account takeover

Getting started

The SimScale platform is a complex application and contains a lot of functionality.

To get an impression of the functionality of the workbench we recommend to walk through one or more tutorials which are also available as video:

Important

During the signup/onboarding process please select the "Community" account and avoid requesting the "Professional Trial". Failure to do so may result in a bounty reward being revoked.

Out of scope

Domain https://www.simscale.com and the remaining paths not listed under SimScale Platform.

Examples:

  • Landing page
  • Documentation
  • Blog
  • Forum

Highlighted

The creation date, last modification date etc of users, public projects and other things which are meant to be public, are not considered to be sensitive. If information is not mentioned in the web application, it is not sensitive by default. Any information disclosure that does not contain PII or other information that cannot directly be used to cause harm to the company or its users, on endpoints mentioned below will be closed as out of scope.

  • https://www.simscale.com/api/v1/projects/*
  • www.simscale.com/forum/users/*.json
  • Other endpoints that disclose similar information as the above

If the endpoint does contain PII of a user, please make sure that it is not mentioned anywhere on the website.

Application

  • 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 on pages with no sensitive actions
  • Host header injection without proven business impact
  • Blind SSRF without proven business impact (DNS pingback only is not sufficient)
  • Disclosed and/or misconfigured Google API key (including maps)
  • Sessions not being invalidated (logout, enabling 2FA, ..)
  • Hyperlink injection/takeovers
  • Mixed content type issues
  • Cross-domain referer leakage
  • Anything related to email spoofing, SPF, DMARC or DKIM
  • Content injection
  • Username / email enumeration
  • E-mail bombing
  • HTTP Request smuggling without any proven impact
  • Homograph attacks
  • XMLRPC enabled
  • Banner grabbing / Version disclosure
  • Open ports without an accompanying proof-of-concept demonstrating vulnerability
  • Weak SSL configurations and SSL/TLS scan reports
  • Not stripping metadata of images
  • Disclosing API keys without proven impact
  • Same-site scripting
  • Subdomain takeover without taken over the subdomain
  • Arbitrary file upload without proof of the existence of the uploaded file

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, may be excluded or be lowered in severity
  • Spam, social engineering and physical intrusion
  • DoS/DDoS attacks or brute force attacks
  • Vulnerabilities that are limited to non-current browsers (older than 3 versions) will not be accepted
  • 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

Out of scope domains

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

This program follows Intigriti's contextual CVSS standard.
