DRACOON

DRACOON offers secure file sharing and collaboration services with two products, DRACOON Cloud and DRACOON Server. Both products support built-in end-to-end encryption and offer many features tailored for large organizations, such as a complex roles and permissions system, SSO integration, auditing and reporting features.

With this bug bounty program, we want to reinforce our commitment to security and reward security researchers for helping us protect our customers' data.

Program Rules

DRACOON wants to increase the security of its products by inviting security researchers to analyze the implementation of security measures in its product and to identify existing vulnerabilities. In order to achieve this goal together, it is important to us that the following rules are adhered to.

  • (D)DoS attacks on our infrastructure are strictly prohibited. This includes (but is not limited to) all applications, services, servers and network infrastructure.
  • Do not carry out load-based attacks (e.g. automated scanners that create a large number of requests).
  • Do not interfere with any box that is not listed within the program scope.
  • Do not decommission any boxes.
  • Do not change network configuration.
  • Do not change passwords of accounts (unless it’s your own) or delete other accounts.
  • Do not extract information and disclose it if you should gain access to it irregularly.
  • Do not alter, modify or delete any information stored in our cloud if you should gain access to it irregularly.
  • Do not publish (even partially) any vulnerabilities that are found.

Reward Eligibility

We are happy to thank everyone who submits valid reports to improve the security of our cloud service, however only those that meet the following eligibility requirements may receive a monetary reward:

  • You must be the first reporter of a vulnerability.
  • The vulnerability must be a qualifying vulnerability (see below).
  • Any vulnerability found must be reported no later than 24 hours after discovery and exclusively through http://yeswehack.com.
  • The vulnerability report must contain the following elements:
    1. A clear textual description of the vulnerability, how it can be exploited, its security impact and remediation advice.
    2. A proof of the exploitation of the vulnerability (e.g. screenshots, proof of concept code).
    3. The preconditions and steps required to reproduce the issue including code snippets, commands, request information, payloads, etc.
  • You must not be a former or current employee of our company or one of its contractors.
