Casambi Vulnerability Disclosure Policy

Introduction

Casambi Technologies Oy (Casambi) is committed to ensuring the security of its customers and users by protecting their information. This policy is intended to give security researchers clear guidelines for conducting vulnerability discovery activities and to convey our preferences in how to submit discovered vulnerabilities to us.

This policy describes what systems and types of research are covered under this policy, how to send us vulnerability reports, and how long we ask security researchers to wait before publicly disclosing vulnerabilities.

We encourage you to contact us to report potential vulnerabilities in our systems.

Authorization

If you make a good faith effort to comply with this policy during your security research, we will consider your research to be authorized. We will work with you to understand and resolve the issue quickly, and Casambi will not recommend or pursue legal action related to your research. Should legal action be initiated by a third party against you for activities that were conducted in accordance with this policy, we will make this authorization known.

Guidelines

Under this policy, “research” means activities in which you:

• Notify us as soon as possible after you discover a real or potential security issue.
• Make every effort to avoid privacy violations, degradation of user experience, disruption to production systems, and destruction or manipulation of data.
• Only use exploits to the extent necessary to confirm a vulnerability’s presence. Do not use an exploit to compromise or exfiltrate data, establish persistent command line access, or use the exploit to pivot to other systems.
• Provide us a reasonable amount of time, at least 30 days, to resolve the issue before you disclose it publicly.
• Do not submit a high volume of low-quality reports.

Once you’ve established that a vulnerability exists or encounter any sensitive data (including personally identifiable information, financial information, or proprietary information or trade secrets of any party), you must stop your test, notify us immediately, and not disclose this data to anyone else.

Test methods

The following test methods are not authorized:

• Network denial of service (DoS or DDoS) tests or other tests that impair access to or damage a system or data
• Automated scanners that generate significant volumes of traffic
• Automated form submission on public webpage, e.g. contact or registration forms
• Physical testing (e.g. office access, open doors, tailgating), social engineering (e.g. phishing, vishing), or any other non-technical vulnerability testing

Scope

This policy applies to the following systems and services:

• Internet-facing services in *.casambi.com subdomains, except domains noted below in “Out-of-scope services”
• We consider the following subdomains to be the most relevant for security research: admin.casambi.com, api.casambi.com, door.casambi.com and bridge.casambi.com
• Desktop and mobile applications provided by Casambi
• Proprietary mesh networks using technology provided by Casambi

Out-of-scope services:

• Main site at casambi.com (this is a marketing site maintained by a third party)
• Support site at support.casambi.com
• Pages at learn.casambi.com
• Development or test deployments of services (recognized by “dev” or “test” somewhere in the domain name, e.g. api.dev.casambi.com)

Any service not expressly listed above, such as any connected services, are excluded from scope and are not authorized for testing. Additionally, vulnerabilities found in systems from our vendors fall outside of this policy’s scope and should be reported directly to the vendor according to their disclosure policy (if any).

If there is a particular system not in scope that you think merits testing, please contact us to discuss it first. We will increase the scope of this policy over time.

Reporting a vulnerability

Information submitted under this policy will be used for defensive purposes only – to mitigate or remediate vulnerabilities. If your findings include newly discovered vulnerabilities that affect other users of a product or service and not solely Casambi, we may privately share your report with other affected parties. We will not share your name or contact information without express permission.

Currently the only channel we use for receiving vulnerability reports is by email at the address casambisecurity@casambi.com. We do not currently have any on-going partnership with any vulnerability management platform.

What we would like to see from you

In order to help us triage and prioritize submissions, we recommend that your reports:

• Describe the location the vulnerability was discovered and the potential impact of exploitation.
• Offer a detailed description of the steps needed to reproduce the vulnerability (proof of concept scripts or screenshots are helpful). If possible, please report the steps as actions of a victim user using a normal browser. Vulnerabilities that require tools like Burp Suite to be demonstrated are much less likely to be considered relevant.
• Be in English, if possible.

What you can expect from us

When you choose to share your contact information with us, we commit to coordinating with you as openly and as quickly as possible.

• Within 5 business days, we will acknowledge that your report has been received.
• To the best of our ability, we will confirm the existence of the vulnerability to you and be as transparent as possible about what steps we are taking during the remediation process, including on issues or challenges that may delay resolution.
• We will maintain an open dialogue to discuss issues.

Rewards

Please note that any bug bounty programs that may have existed in the past are currently on hold. At present Casambi is not offering money nor any other monetary rewards for reporting vulnerabilities.
