CVE-2024-38487: API Gateway Privilege Escalation Flaw

CVE-2024-38487 Overview

CVE-2024-38487 is a container privilege escalation vulnerability affecting the api-gateway container in Dell VxRail. The container runs with root privilege, which would allow an attacker to escape the container boundary and access the underlying host system. Once on the host, the attacker can perform unintended actions outside the container's intended security boundary. The vulnerability is categorized under [CWE-269] Improper Privilege Management and requires local access with low privileges to exploit.

Critical Impact
Successful exploitation enables container escape from the api-gateway container to the host, exposing host-level resources and impacting confidentiality, integrity, and availability of the VxRail node.

Affected Products

Dell VxRail 7.0.520
Dell VxRail api-gateway container component
Third-party components bundled with Dell VxRail (per DSA-2024-247)

Technical Details for CVE-2024-38487

Vulnerability Analysis

The api-gateway container in Dell VxRail executes with root-level privileges inside the container runtime. When a container process runs as root and shares namespaces or sensitive mounts with the host, the isolation boundary becomes thin. An attacker who gains code execution inside the container inherits root capabilities and can target host resources reachable from that context.

The attack chain is local, meaning the attacker must already have a foothold on the system. Exploitation complexity is high because it depends on the container configuration and the attacker's ability to abuse root capabilities to break out. Impact spans confidentiality, integrity, and availability because host access permits arbitrary actions outside the intended container scope.

Root Cause

The root cause is improper privilege management ([CWE-269]). The api-gateway container is configured to run as the root user instead of a non-privileged service account. This violates least-privilege principles for containerized workloads and removes a layer of defense against container-to-host escapes.

Attack Vector

An attacker with low-privileged local access to the VxRail environment must first reach the api-gateway container, for example through an application-layer flaw or an authenticated management interface. Because the container runs as root, the attacker can leverage Linux capabilities, writable host mounts, or shared namespaces to interact with the host kernel and filesystem. The scope is changed, indicating that exploitation impacts components beyond the vulnerable container itself.

No public proof-of-concept exploit is available, and the vulnerability is not listed in the CISA Known Exploited Vulnerabilities catalog. The EPSS probability is low, reflecting limited observed exploitation interest at this time.

Detection Methods for CVE-2024-38487

Indicators of Compromise

Unexpected processes spawned by the api-gateway container that reference host paths such as /proc/1/root, /host, or /var/run/docker.sock.
Container processes invoking nsenter, chroot, mount, or setns system calls outside normal operation.
New or modified files under host directories that should not be writable from container workloads.

Detection Strategies

Audit container runtime configuration to identify containers running as UID 0 with privileged flags, host PID namespace, or host filesystem mounts.
Inspect Kubernetes or Docker manifests for privileged: true, hostPID, hostNetwork, and missing runAsNonRoot enforcement.
Correlate container process activity with host-level events using kernel auditing or eBPF-based runtime monitoring.

Monitoring Recommendations

Continuously monitor the api-gateway container for execution of shells, package managers, or kernel module operations.
Alert on unexpected outbound connections from the container to host management interfaces or internal control planes.
Review syslog and audit logs on VxRail nodes for capability escalations originating from container runtime processes.

How to Mitigate CVE-2024-38487

Immediate Actions Required

Apply the remediation provided in Dell Security Update DSA-2024-247 for Dell VxRail 7.0.520.
Restrict local and management-plane access to VxRail nodes to authorized administrators only.
Inventory all VxRail clusters and confirm the api-gateway container version after patching.

Patch Information

Dell has published security guidance for this issue in advisory DSA-2024-247, covering Dell VxRail 7.0.520 and multiple third-party component vulnerabilities. Administrators should follow the vendor advisory for the exact fixed build and upgrade procedure: Dell Security Update 2024-247.

Workarounds

Limit who can authenticate to the VxRail management interfaces and reduce the attack surface that could reach the api-gateway container.
Enforce network segmentation between VxRail management networks and general user or workload networks.
Where supported by the vendor, review container security context settings to ensure non-root execution and minimal Linux capabilities once a patched build is deployed.

bash

# Configuration example: identify containers running as root on a host
docker ps --quiet | while read cid; do
  user=$(docker inspect --format '{{.Config.User}}' "$cid")
  name=$(docker inspect --format '{{.Name}}' "$cid")
  if [ -z "$user" ] || [ "$user" = "0" ] || [ "$user" = "root" ]; then
    echo "Container $name ($cid) is running as root"
  fi
done
