昨天看到oschina上的 报道gitlab存在权限泄露漏洞。幸运的是官方同时释放出新版并给出了修复方案。私人的代码仓库基于gitlab搭建,所以也必须修复,以防被恶意利用。

打开gitlab的官方博客的 更新说明,内容基本上和 oschina的报道 一致。于是按照官方指引修复:

  1. 更新gitlab到最新版: yum update -y gitlab-ce
  2. 新建 /opt/gitlab/embedded/service/gitlab-rails/lib/tasks/reset_token.rake 文件,并往文件中输入以下内容:
# lib/tasks/reset_token.rake
require_relative '../../app/models/concerns/token_authenticatable.rb'

STDOUT.sync = true

namespace :tokens do
  desc "Reset all GitLab user auth tokens"
  task reset_all: :environment do
    reset_all_users_token(:reset_authentication_token!)
  end

  desc "Reset all GitLab email tokens"
  task reset_all_email: :environment do
    reset_all_users_token(:reset_incoming_email_token!)
  end

  def reset_all_users_token(token)
    TmpUser.find_in_batches do |batch|
      puts "Processing batch starting with user ID: #{batch.first.id}"

      batch.each(&token)
    end
  end
end

class TmpUser < ActiveRecord::Base
  include TokenAuthenticatable

  self.table_name = 'users'

  def reset_authentication_token!
    write_new_token(:authentication_token)
    save!(validate: false)
  end

  def reset_incoming_email_token!
    write_new_token(:incoming_email_token)
    save!(validate: false)
  end
end
  1. 执行token重置命令:
sudo gitlab-rake tokens:reset_all
sudo gitlab-rake tokens:reset_all_email

成功的大致输出为:Processing batch starting with user ID: xxx

修复过程中有个插曲:对于用包管理的用户,以为建立文件即可。运行gitlab-rake tokens:reset_all时会出现错误提示:

D, [2017-03-22T10:44:47.573742 #22045] DEBUG -- sentry: ** [Raven] Don't know how to build task 'tokens:r
eset_all' (see --tasks) excluded from capture due to environment or should_capture callback
rake aborted!

在官方论坛上,有人就这个输出发了一个 issue(犯了和我同样的错误),还好大神很快就出来解答了^_`
