CVE-2025-54469: 
Wolfi vulnerability analysis and mitigation

A critical vulnerability (CVE-2025-54469) was discovered in NeuVector's Enforcer container, affecting versions 5.3.0 through 5.4.6. The vulnerability, assigned a CVSS score of 10.0, was disclosed in October 2025 and involves a command injection flaw in the container's monitor process (Security Online, GitHub Advisory).

The vulnerability exists in the Enforcer container's monitor process, which uses environment variables CLUSTERRPCPORT and CLUSTERLANPORT to generate commands executed via popen function. The critical flaw stems from these environment variables being used directly to compose shell commands without proper validation or sanitization. When the Enforcer container stops, the monitor process checks for consul subprocess exit status by executing shell commands using these unsanitized variables (GitHub Advisory).

The vulnerability enables attackers to achieve root-level code execution within the Enforcer container, potentially leading to complete compromise of the containerized environment, lateral movement within the Kubernetes cluster, tampering with NeuVector's runtime security enforcement, and privilege escalation if the container runs with elevated permissions (Security Online).

SUSE has released patches in NeuVector version 5.4.7 and 5.3.5, which implement validation for the CLUSTERRPCPORT and CLUSTERLANPORT environment variables. The patched version ensures these variables contain only valid port numbers before executing popen commands, with immediate container termination if validation fails. No workarounds are available, and users are strongly advised to upgrade to a patched version immediately (GitHub Advisory).
