Security Reporting

From Proxmox VE
Jump to navigation Jump to search

Proxmox Server Solutions takes security of its projects seriously. As such, we'd like to know when a security bug is found so that it can be fixed and disclosed in a timely manner.

Note that we only support the latest point release, where the version is not yet EOL (End of Life). So, before reporting, please verify that the issue is present in a release that is still supported. For that, consider the following support timeline tables:

Contact

Please report security bugs to the Proxmox security team by email at <security@proxmox.com>.

Include all relevant information required to reproduce the issue.

Any exploit code is considered helpful - we will treat such samples as private and won't publish them. If you or your organization already assembled a fix and has signed our CLA please send that along as patch, as that can speed up the process considerably.

Please send plain text emails without attachments where possible. It is much harder to have a context-quoted discussion about a complex issue if all the details are hidden away in attachments.

We will normally send out an initial confirmation mail about the reception of a report within the next (Austrian) business day.

If you must send highly confidential information you may use the following public GPG key, with fingerprint E679 2AA6 98E1 1855 375A B9E3 5D0C BD43 61F2 04C5 to encrypt the message.

Disclosure and Embargoed Information

Once a robust fix has been developed, the release process starts. Proxmox Server Solutions will release fixes for publicly undisclosed bugs as soon as they become available, but we can hold back sensible information from commits and change logs at the requests of the reporter or an affected party.

CVE assignment

The security team does not normally assign CVEs, nor do we require them for reports or fixes, as this can needlessly complicate the process and may delay the bug handling.

We would still appreciate if you notify us about any assigned ID, for coordination and communication purpose.

Infrastructure Issues

If you found an issue within our infrastructure's software we'd appreciate if you use one of the following approaches, depending on the kind of bug in question:

  • for bugs in the underlying software we recommend contacting the respective upstream, if that isn't active anymore it can make sense to give our security team a heads-up
  • for configuration bugs, you can follow the standard reporting procedure above and contact us via email
Please note, however, that problems found by automatic scanners are often either outdated practices or have little practical impact (e.g., on websites where the browser can already take care of protection itself).
Some scanners also report our email settings as problematic, but they are deliberately chosen because we also operate various email services such as mailing lists that require special attention.

Bug Bounties

Proxmox Server Solutions GmbH currently does not offer paid bug bounties. We understand that security research takes a lot of effort, and we'll periodically evaluate if we can allocate some funding in the future.
