Description

Keylime registrar is vulnerable to Denial-of-Service attack when updated to version 7.12.0

Impact

The Keylime registrar implemented more strict type checking on version 7.12.0. As a result, when updated to version 7.12.0, the registrar will not accept the format of the data previously stored in the database by versions >= 7.8.0, raising an exception.

This makes the Keylime registrar vulnerable to a Denial-of-Service attack in an update scenario, as an attacker could populate the registrar database by creating multiple valid agent registrations with different UUIDs while the version is still < 7.12.0. Then, when the Keylime registrar is updated to the 7.12.0 version, any query to the database matching any of the entries populated by the attacker will result in failure.

Patches

Users should upgrade to versions >= 7.12.1

Workarounds

  • Remove the registrar database and re-register all agents

The scope is unchanged, so the impact stays within the vulnerable component. Rated impact: confidentiality none, integrity none, availability low.

CVSS metrics in full

The score comes from this vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:L

  • Attack vector: Network — reachable from anywhere that can route to the service.
  • Attack complexity: Low — the attack works reliably, with no preparation.
  • Privileges required: None — an unauthenticated stranger can try it.
  • User interaction: Required — someone has to click, open or visit something.
  • Scope: Unchanged — the damage stays inside the vulnerable component.
  • Confidentiality impact: None.
  • Integrity impact: None.
  • Availability impact: Low — limited, and the attacker does not choose what is affected.
