Reward Details

Reward eligibility criteria

Please provide any information we need to reproduce the reported issues. The size of each reward depends on the severity of the reported vulnerability and which product category is affected.

To qualify for monetary rewards, reports must meet the following criteria:

You are the first researcher to report this vulnerability
The reported vulnerability is confirmed to be verifiable, replicable, and a valid security issue
Your report complies with the Bounty Program’s terms and regulations

Reporting security bugs

If you believe you have found a vulnerability, please follow the steps below:

Step 1

Step 2

Use this PGP key to encrypt your information when sending bug reports to Synology.

Step 3

Include a detailed proof of concept (PoC) and make sure that the reported issues can be reproduced.

Step 4

Keep your description succinct. For example, a short proof-of-concept link is valued higher than a video explaining the consequences of an SSRF issue.

Your and our responsibilities

Your report

To reduce our processing time, a good vulnerability report should:

Contain a clearly written step-by-step description in English of how to reproduce the vulnerability
Demonstrate how the vulnerability affects Synology products or web services, and describe which versions and platforms are affected
State the potential damage caused by the reported vulnerability

Our response

The Synology Security Team will respond to your report within 7 days and regular update the status and fix the vulnerability as soon as possible, depending on the severity of the threat posed.

If your vulnerability report qualifies for a monetary reward, your name will be listed on the Synology Product Security Advisory page on our official website as a gesture of our appreciation.

This process will take at least 90 days. Your reward will be transferred to you upon completion of the process.

Notes:Synology reserves the right to change or cancel this program, including its policies, at any time without prior notice.

For issues classified as low severity or suggestions, only acknowledgements will be provided.

FAQs

How should I report a vulnerability? Please provide detailed PoC (Proof of Concept) and make sure the reported issues can be reproduced. Use this PGP key encryption offered by Synology when sending bug reports to us and do not disclose the relevant information to any third party.Who is responsible for determining whether my bug report is eligible for a reward?All the bug reports are reviewed and evaluated by Synology Security Team, which is comprised of Synology’s senior security analysts. What is the consequence if a bug is publicly disclosed before being fixed? We endeavor in responding to bug reports promptly and fixing them within a reasonable time period. Please notify us in advance before you publicly disclose the bug information. Any bug disclosure without following this principle will not be qualified for a reward.Are vulnerabilities found in outdated software such as Apache or Nginx qualified for a reward?Please identify the vulnerabilities in the software and explain why you suspect they are detrimental to software use. Reports omitting this type of information are usually not qualified for a bounty. Can I request that my name not be listed on Synology’s Security Advisory page?Yes. You can request not to be listed on our Security Advisory page. However, if you are qualified for a reward and wish to accept it, we will still need your contact information to process the payment.Are vulnerabilities still eligible for a reward if they are reported to vulnerability brokers?Privately disclosing a vulnerability to third parties for purposes other than bug fixing is contradictory to the spirit of our program. Therefore, such reports will not be qualified for a reward. Who is qualified for a bounty if the same bug is reported by more than one person?The reward is granted to the first person who discovers a vulnerability that was previously unknown to us.
