From 42581dfe93a0eb417dddc5fd66876ef24896bff5 Mon Sep 17 00:00:00 2001 From: Clement Michaud Date: Sat, 27 Oct 2018 18:18:25 +0200 Subject: [PATCH] Fix open redirection vulnerability. In order to redirect the user after authentication, Authelia uses rd query parameter provided by the proxy. However an attacker could use phishing to make the user be redirected to a bad domain. In order to avoid the user to be redirected to a bad location, Authelia now verifies the redirection URL is under the protected domain. --- Gruntfile.js | 10 ++++- client/src/lib/SafeRedirect.ts | 10 +++++ client/src/lib/firstfactor/index.ts | 5 ++- client/src/lib/secondfactor/U2FValidator.ts | 14 +------ client/src/lib/secondfactor/index.ts | 36 +++++++++------- client/src/lib/u2f-register/u2f-register.ts | 5 ++- server/src/lib/routes/firstfactor/get.ts | 40 ++++++++++++------ server/src/lib/routes/firstfactor/post.ts | 10 +++-- .../secondfactor/u2f/sign_request/get.ts | 2 +- .../src/lib/routes/verify/get_basic_auth.ts | 2 +- .../lib/routes/verify/get_session_cookie.ts | 2 +- server/src/lib/utils/DomainExtractor.ts | 6 --- server/src/lib/utils/SafeRedirection.spec.ts | 33 +++++++++++++++ server/src/lib/utils/SafeRedirection.ts | 22 ++++++++++ server/src/views/secondfactor.pug | 2 +- shared/BelongToDomain.ts | 8 ++++ .../utils => shared}/DomainExtractor.spec.ts | 13 +++++- shared/DomainExtractor.ts | 11 +++++ shared/UserMessages.ts | 2 + test/complete-config/closed-redirection.ts | 41 +++++++++++++++++++ .../mongo-broken-connection.ts | 22 +++++----- test/environment.ts | 2 +- test/helpers/full-login.ts | 12 ++++++ test/helpers/login-and-register-totp.ts | 5 +-- test/helpers/login-as.ts | 2 - test/minimal-config/bad_password.ts | 8 +--- test/minimal-config/fail_totp.ts | 11 +---- test/minimal-config/reset_password.ts | 1 - test/minimal-config/validate_totp.ts | 16 ++------ 29 files changed, 248 insertions(+), 105 deletions(-) create mode 100644 client/src/lib/SafeRedirect.ts delete mode 100644 server/src/lib/utils/DomainExtractor.ts create mode 100644 server/src/lib/utils/SafeRedirection.spec.ts create mode 100644 server/src/lib/utils/SafeRedirection.ts create mode 100644 shared/BelongToDomain.ts rename {server/src/lib/utils => shared}/DomainExtractor.spec.ts (53%) create mode 100644 shared/DomainExtractor.ts create mode 100644 test/complete-config/closed-redirection.ts create mode 100644 test/helpers/full-login.ts diff --git a/Gruntfile.js b/Gruntfile.js index 28bdd6d8e..f8b33fd11 100644 --- a/Gruntfile.js +++ b/Gruntfile.js @@ -9,6 +9,9 @@ module.exports = function (grunt) { }, "env-test-client-unit": { TS_NODE_PROJECT: "client/tsconfig.json" + }, + "env-test-shared-unit": { + TS_NODE_PROJECT: "server/tsconfig.json" } }, run: { @@ -37,6 +40,10 @@ module.exports = function (grunt) { cmd: "./node_modules/.bin/mocha", args: ['--colors', '--require', 'ts-node/register', 'server/src/**/*.spec.ts'] }, + "test-shared-unit": { + cmd: "./node_modules/.bin/mocha", + args: ['--colors', '--require', 'ts-node/register', 'shared/**/*.spec.ts'] + }, "test-client-unit": { cmd: "./node_modules/.bin/mocha", args: ['--colors', '--require', 'ts-node/register', 'client/test/**/*.test.ts'] @@ -193,8 +200,9 @@ module.exports = function (grunt) { grunt.registerTask('compile-client', ['run:lint-client', 'run:compile-client']) grunt.registerTask('test-server', ['env:env-test-server-unit', 'run:test-server-unit']) + grunt.registerTask('test-shared', ['env:env-test-shared-unit', 'run:test-shared-unit']) grunt.registerTask('test-client', ['env:env-test-client-unit', 'run:test-client-unit']) - grunt.registerTask('test-unit', ['test-server', 'test-client']);
