CVE-2022-38734 is a high-severity uncontrolled resource consumption vulnerability in Denial of Service Vulnerability in StorageGRID (formerly StorageGRID Webscale), with a CVSS 3.1 base score of 7.5 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. Affected Denial of Service Vulnerability in StorageGRID (formerly StorageGRID Webscale) versions: prior to 11.6.0.8. The record does not name a fixed version, so check the vendor advisory. There is no confirmed exploitation so far. EPSS estimates a 0.62% chance of exploitation within 30 days, higher than 50% of scored CVEs.

Next patch cycle

High severity with no evidence of exploitation so far.

What to do

  1. Update Storagegrid to 11.6.0.8 or a later version.
  2. Read the advisory on security.netapp.com for workarounds and exact fixed builds.
  3. Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.

The underlying weakness: Uncontrolled Resource Consumption

The product does not properly control the allocation and maintenance of a limited resource.

How developers prevent this class of flaw

  • Ensure that protocols have specific limits of scale placed on them.
  • Ensure that all failures in resource allocation place the system into a safe posture.
