CVE-2025-54469 NeuVector Enforcer is vulnerable to Command Injection and Buffer overflow

What is CVE-2025-54469?

CVE-2025-54469 is a critical command injection vulnerability in SUSE neuvector, published on 30 Oct 2025. Any signed-in user can exploit it over the network, with no action from the victim.

Official description

A vulnerability was identified in NeuVector, where the enforcer used environment variables CLUSTER_RPC_PORT and CLUSTER_LAN_PORT to generate a command to be executed via popen, without first sanitising their values.

The entry process of the enforcer container is the monitor process. When the enforcer container stops, the monitor process checks whether the consul subprocess has exited. To perform this check, the monitor process uses the popen function to execute a shell command that determines whether the ports used by the consul subprocess are still active.

The values of environment variables CLUSTER_RPC_PORT and CLUSTER_LAN_PORT are used directly to compose shell commands via popen without validation or sanitization. This behavior could allow a malicious user to inject malicious commands through these variables within the enforcer container.

Weakness: CWE-78
