CVE-2024-6387 - Qualys Security Advisory - Update Advisory

ItemDescription
DescriptionOpenSSH Remote Code Execution due to Race Condition in Signal Handling (CVE-2024-6387)
Severity8.1
Impact to CoreWeave PlatformThe CoreWeave platform and supporting infrastructure have been upgraded to prevent exploitation of this issue.
Potentially Affected ClientsClients running vulnerable versions of OpenSSH server are vulnerable to this CVE. Clients running an OpenSSH server version equal to or greater than “8.5p1” and less than “9.8p1” are vulnerable to this issue and should take steps to remediate. In particular, clients using VirtualServers and Slurm may need to take action to upgrade their SSH servers to a patched version or use workarounds which prevent exploitation.
Actions TakenPatching and Updates: Updates have been deployed inside of the CoreWeave platform and its supporting infrastructure.

System Status: As of July 2nd, 2024 CoreWeave systems are operational and no outages to support upgrade operations are planned.

Recommended Client Actions: Clients which run a VirtualServer, container, or Slurm login Pod that uses a version of OpenSSH server should upgrade their VirtualServer, container image, or Slurm login/compute Pod images in order to obtain a patched version. Alternatively, clients may apply workarounds to their SSH server configuration to limit or prevent exploitability.

Clients running an OpenSSH server version equal to or greater than “8.5p1” and less than “9.8p1” are vulnerable to this issue and should take steps to remediate.

SUNK/Slurm User Guidance

Clients who are not on a CoreWeave-managed instance of SUNK and who meet the criteria below should take action to ensure that SUNK is patched against CVE-2024-6387:
  • Are using SUNK versions 3.20.0 through 4.3.0
  • Are using Ubuntu images in SUNK of 22.04 or higher
If the criteria above are met, clients should take the following actions:
  • Add the following items to the s6 configuration for both login and compute Nodes in the chart values.yaml being used to deploy CoreWeave’s Slurm chart:
login:
  s6:
    ssh-patch:
      type: oneshot
      script: |
        #!/usr/bin/env bash
        groupadd messagebus
        apt update && apt install --only-upgrade openssh-server -y
compute:
  s6:
    ssh-patch:
      type: oneshot
      script: |
        #!/usr/bin/env bash
        groupadd messagebus
        apt update && apt install --only-upgrade openssh-server -y
  • Deploy these changes (if using ArgoCD, sync the changes with the cluster).
This will roll the NodeSet Pods for the compute Nodes. If login StatefulSets are set to use the OnDelete update strategy, then the login Pods to all that will be upgraded with these changes will need to be manually deleted. See the official Kubernetes documentation on StatefulSet update strategies for more information.
If using custom build images for SUNK, these commands can be integrated into the image build instead.

CVE-2022-42475

ItemDescription
DescriptionA heap-based buffer overflow vulnerability [CWE-122] in FortiOS SSL-VPN may allow a remote unauthenticated attacker to execute arbitrary code or commands via specifically crafted requests.
Severity9.3
Impact to CoreWeave PlatformCurrently no known impact to CoreWeave Platform
Potentially Affected ClientsClients using FortiOS
Recommended ActionsVendor-recommended mitigations
FortiGuard Labs has confirmed at least one instance of vulnerability CVE-2022-42475 being exploited in the wild. Given the high value (CVE critical severity rating 9.3) and relatively low complexity of this vulnerability, CoreWeave strongly recommends upgrading to an unaffected version of FortiOS on an accelerated patch schedule, according to vendor recommendations. Vulnerability checks for CVE-2022-42475 are available from a variety of sources. Please use caution when running any script or application to ensure it is safe. At this time there is no impact to CoreWeave’s platform, however customers who have FortiOS running within their environment are advised to review the vendor-recommended mitigations, and take appropriate self measures to upgrade their deployments and evaluate their systems for any indicators of compromise. Our cyber security team is closely monitoring the situation, and will provide important updates should more information become available.
