Helix Core: Uncontrolled Resource Consumption

CVE-2023-35767 is a high-severity uncontrolled resource consumption vulnerability in Helix Core from Helix, 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. The record lists versions 2023.2, 2023.1 Patch 2, 2022.2 Patch 3 as the first without the flaw, so updating Helix Core to one of those releases or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 1.25% chance of exploitation within 30 days, higher than 70% of scored CVEs.

Next patch cycle

High severity with no evidence of exploitation so far.

What to do

  1. Update Helix Core to 2023.2 or 2023.1 Patch 2 or 2022.2 Patch 3 or 2022.1 Patch 6, whichever matches your release line, or a later version.
  2. Update Helix Swarm to 2024.1 or a later version.
  3. Update helix_core to 2023.1\/patch_2\/ or 2022.2\/patch_3\/ or 2022.1\/patch_6\/ or 2021.2\/patch_10\/, whichever matches your release line, or a later version.
  4. Read the advisory on perforce.com for workarounds and exact fixed builds.
  5. 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.
