Detailsinfo

A vulnerability has been found in SUSE neuvector up to 5.3.4/5.4.6 and classified as critical. Affected by this vulnerability is the function popen. The manipulation of the argument CLUSTER_RPC_PORT/CLUSTER_LAN_PORT with an unknown input leads to a os command injection vulnerability. The CWE definition for the vulnerability is CWE-78. The product constructs all or part of an OS command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended OS command when it is sent to a downstream component. As an impact it is known to affect confidentiality, integrity, and availability. The summary by CVE is:

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.

The advisory is shared at bugzilla.suse.com. This vulnerability is known as CVE-2025-54469 since 07/23/2025. The exploitation appears to be easy. The attack can be launched remotely. Technical details are known, but no exploit is available. The price for an exploit might be around USD $5k-$25k at the moment (estimation calculated on 10/30/2025). MITRE ATT&CK project uses the attack technique T1202 for this issue.

Upgrading to version 0.0.0-20251020133207-084a437033b4, 5.3.5 or 5.4.7 eliminates this vulnerability.
