Vulnerability Disclosure Policy
This vulnerability disclosure policy applies to any vulnerabilities you are considering reporting to Avantgarde Finance. We recommend reading this vulnerability disclosure policy fully before you report a vulnerability and always acting in compliance with it. We value those who take the time and effort to report security vulnerabilities according to this policy. However, we do not offer monetary rewards for vulnerability disclosures.
If you believe you have found a security vulnerability, please submit your report to us using the following email:
In your report please include details of:
- The website, IP or page where the vulnerability can be observed.
- A brief description of the type of vulnerability, for example; “XSS vulnerability”.
- Steps to reproduce. These should be a benign, non-destructive, proof of concept. This helps to ensure that the report can be triaged quickly and accurately. It also reduces the likelihood of duplicate reports, or malicious exploitation of some vulnerabilities.
After you have submitted your report, we will respond to your report within 3 working days and aim to triage your report within 6 working days. We’ll also aim to keep you informed of our progress.
Once triaged, priority for remediation is assessed by looking at the impact, severity and exploit complexity but we aim to remediate as follows:
- HIGH priority - within 1 week
- MEDIUM priority - within 2 weeks
- LOW priority - within 1 month
You are welcome to enquire on the status but should avoid doing so more than once every 14 days. This allows our teams to focus on the remediation. We will notify you when the reported vulnerability is remediated, and you may be invited to confirm that the solution covers the vulnerability adequately.
Once your vulnerability has been resolved, we welcome requests to disclose your report to unify guidance to affected users, so please do continue to coordinate public release with us.
- Break any applicable law or regulations.
- Access unnecessary, excessive or significant amounts of data.
- Modify data in Avantgarde Finance's systems or services.
- Use high-intensity invasive or destructive scanning tools to find vulnerabilities.
- Attempt or report any form of denial of service, e.g. overwhelming a service with a high volume of requests.
- Disrupt the Avantgarde Finance's services or systems.
- Submit reports detailing non-exploitable vulnerabilities, or reports indicating that the services do not fully align with “best practice”, for example missing security headers.
- Submit reports detailing TLS configuration weaknesses, for example “weak” cipher suite support or the presence of TLS1.0 support.
- Communicate any vulnerabilities or associated details other than by means described in the published security.txt.
- Social engineer, ‘phish’ or physically attack the Avantgarde Finance's staff or infrastructure.
- Demand financial compensation in order to disclose any vulnerabilities.
Always comply with data protection rules and must not violate the privacy of the Avantgarde Finance's users, staff, contractors, services or systems. You must not, for example, share, redistribute or fail to properly secure data retrieved from the systems or services.
Securely delete all data retrieved during your research as soon as it is no longer required or within 1 month of the vulnerability being resolved, whichever occurs first (or as otherwise required by data protection law).
This policy is designed to be compatible with NCSC guidance and common vulnerability disclosure good practice. It does not give you permission to act in any manner that is inconsistent with the law, or which might cause Avantgarde Finance or it’s partner organisations to be in breach of any legal obligations.
