Products and areas 14

  • Disk image handling for VDI, VMDK, VHD and the other supported formats, plus OVF and OVA appliance import
  • Oracle's reporting page is the declared channel: PGP-encrypted email to the security alert address, with fixes shipped in the quarterly Critical Patch Update and credit given in the advisory. virtualbox.org routes security findings there and away from the public tracker. Nothing narrower is declared, so the whole product is in
  • Shared folders in full, on every host platform
  • The 3D acceleration and graphics stack, where guest-supplied rendering commands are interpreted by host code
  • The emulated network adapters, including E1000, PCnet and virtio-net, plus the user-space NAT stack behind them
  • The emulated storage controllers in full, including IDE, AHCI, NVMe, LsiLogic and BusLogic
  • The Guest Additions and every host channel they open: shared clipboard, drag and drop, guest properties, guest control, and the VBoxService and VBoxClient pair
  • The HGCM host-guest communication manager and every service registered on it
  • The host kernel drivers on Windows, macOS and Linux, including VBoxDrv and the network filter and adapter drivers
  • The installer and the update mechanism on each host platform, plus the Extension Pack components where they are reachable
  • The VMM core: the hardware virtualization backends, the recompiler paths and the instruction emulation behind both
  • The VRDE remote display server and any other network-facing console path
  • USB emulation across OHCI, EHCI and xHCI, along with the audio and graphics device implementations
  • VBoxSVC and the COM and XPCOM API surface, including how a less privileged host user reaches it
Out of scope (6)
  • Configuration that deliberately removes isolation, for example enabling a writable shared folder and then reporting that the guest wrote to it
  • Findings filed on the public bug tracker, which the project asks you not to use for security issues
  • Guest operating system defects rather than VirtualBox
  • Host operating system defects or CPU errata rather than VirtualBox's handling of them
  • Other Oracle products, which share the reporting address but are entirely different targets
  • Third-party front ends such as Vagrant and the various management GUIs

Rules

What the policy asks of you, and the bug types it won't reward, quoted from Sorona's policy. "We" in these lines means Sorona, not this site.

While testing

  • Submit through sorona.xyz. This project runs no bounty of its own; we validate, coordinate disclosure with the maintainers, and pay you directly.
  • Report to the address on the policy page , PGP-encrypted to Oracle's published public key using the step-by-step procedure on the reporting page
  • Do not use the public bug tracker. virtualbox.org routes security findings away from it and to Oracle explicitly
  • State the host platform and version alongside the guest.
  • Say whether the Extension Pack was installed and whether Guest Additions were running.
  • Hold detail until that advisory is out.

Not accepted

  • Guest operating system defects rather than VirtualBox

A guest-to-host escape lands on a machine holding source code, SSH keys and cloud credentials. Oracle takes reports through an encrypted security address and ships fixes in the quarterly Critical Patch Update, where the stated reward is credit in the advisory.
