| タイトル | mauriceboe TREK <= 3.0.22 Improper Authentication |
|---|
| 説明 | MFA bypass via JWT purpose confusion in TREK <= 3.0.22. The authentication system issues a purpose-scoped JWT (mfa_token) after password verification but before TOTP completion. The session verifier does not validate the "purpose" claim, allowing attackers to use this pre-2FA token as a full session token on any authenticated endpoint. An attacker possessing only the victim's password can obtain the mfa_token from POST /api/auth/login and use it as a bearer token to access all protected endpoints and MCP functionality without providing valid TOTP or backup codes. This completely circumvents the second authentication factor. CVSS 9.6 (AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:N). CWE-287, CWE-345. Fixed in 3.1.0. |
