Notification and disclosure Policy

Thanks to Thierry Zoller for the permission to use his policy

Begin of Terms/Policy (based on Secunias' Policy) (Author: Thierry Zoller)


You are not allowed to share any details, proof of concept files with other vendors, should such request arrive please forward them to myself, I will gladly provide them to the respective vendors. You may be quoted or the complete e-mail communication may be published if I deem it necessary for transparency.

  1. If no security contact is known for the vendor and no security contact can be found at OSVDB, an e-mail requesting the security contact e-mail address may initially be sent to certain public e-mail addresses associated with the vendor. Online forms may only be used to request security contact information.
  2. When a security contact or other relevant e-mail address has been identified, a vendor initially receives a mail with vulnerability details along with a pre-set disclosure date (usually set to a Thursday two week later).
  3. If the vendor does not respond to the initial mail within a week, it is resent.
  4. If no response has been received at the day of the pre-set disclosure date, the vulnerability information is published immediately without further coordination attempts.
  5. If the vendor responds to either the initial mail or the resent mail, a new disclosure date may be set in case the vendor cannot meet the pre-set date.
  6. I expect to receive continuous status updates from the vendor and a list of all affected products, should no list be given it is assumed all products are vulnerable. If none are provided by default, the vendor will be contacted about once a month with a status update request (if time permits).
  7. Should a vendor not respond to a status update request, it is resent.
  8. Should the vendor not respond to two consecutive status update requests, a mail is sent to the vendor advising that the vulnerability information will be disclosed a week later if no response is received. Has no response been received by this date, the vulnerability information is immediately published without further coordination attempts.
  9. Eventually, the vulnerability information will be published by me when:
    • The pre-set/agreed disclosure date is reached.
    • The vendor issues a fix and/or security advisory.
    • Information about the same vulnerability is published by a third party.
    • A year from the initial contact date has passed
    • the vendor denies the security nature of the bug and/or gives no credit for my work
  10. Unless the vendor asks for an extension, I will not coordinate a vulnerability disclosure for more than 2 months. After 2 months the details will be published regardless of patch availability.
