Cách sửa lỗi bảo mật Log4j nếu bạn không thể Update lên 2.15.0

Chào mừng các bạn đến với bài hướng dẫn Office tiếp theo trong GOGOhalloween.  

Các nhà nghiên cứu đã phát hiện ra một lỗ hổng nghiêm trọng trong thư viện Apache Log4j, có điểm 10/10 trong CVSS. Dưới đây là bài phân tích và hướng dẫn bạn bảo vệ máy chủ.

Nhiều hãng tin tức bảo mật đã đưa tin về việc phát hiện ra lỗ hổng nghiêm trọng CVE-2021-44228 trong thư viện Apache Log4j (mức độ nghiêm trọng CVSS 10/10). Hàng triệu ứng dụng Java sử dụng thư viện này để ghi lại các thông báo lỗi. Để làm cho vấn đề tồi tệ hơn, những kẻ tấn công đã tích cực khai thác lỗ hổng này. Vì lý do này, Apache Foundation khuyến nghị tất cả các nhà phát triển cập nhật thư viện lên phiên bản 2.15.0 và nếu không được, hãy sử dụng một trong các phương pháp tại đây.


Tại sao CVE-2021-44228 lại nguy hiểm đến vậy

CVE-2021-44228, còn được đặt tên là Log4Shell hoặc LogJam, là một lỗ hổng trong lớp Remote Code Execution (RCE). Nếu những kẻ tấn công khai thác nó trên các máy chủ, chúng sẽ có thể thực thi code tùy ý và có khả năng kiểm soát toàn bộ hệ thống.

Điều khiến CVE-2021-44228 trở nên đặc biệt nguy hiểm là tính dễ bị khai thác: ngay cả một hacker thiếu kinh nghiệm cũng có thể thực hiện thành công một cuộc tấn công bằng cách sử dụng lỗ hổng này. Theo các nhà nghiên cứu, những kẻ tấn công chỉ cần buộc ứng dụng chỉ ghi một chuỗi vào nhật ký và sau đó chúng có thể tải code của chính mình lên ứng dụng nhờ chức năng thay thế tra cứu tin nhắn.

Cách bài viết hướng dẫn tấn công Proofs of Concept (PoC) thông qua CVE-2021-44228 đều đã có sẵn trên Internet. Do đó, không có gì ngạc nhiên khi các công ty an ninh mạng đã thực hiện các đợt quét mạng khổng lồ để tìm các ứng dụng dễ bị tấn công cũng như các cuộc tấn công vào honeypots.

Lỗ hổng này được phát hiện bởi Chen Zhaojun thuộc Đội bảo mật đám mây của Alibaba.


Apache Log4J là gì và tại sao thư viện này lại phổ biến như vậy?

Apache Log4j là một phần của Dự án Apache Logging. Nhìn chung, việc sử dụng thư viện này là một trong những cách dễ nhất để ghi lại lỗi và đó là lý do tại sao hầu hết các nhà phát triển Java sử dụng nó.


Nhiều công ty phần mềm lớn và dịch vụ trực tuyến sử dụng thư viện Log4j, bao gồm Amazon, Apple iCloud, Cisco, Cloudflare, ElasticSearch, Red Hat, Steam, Tesla, Twitter,… Do thư viện này quá phổ biến, nên một số nhà nghiên cứu bảo mật thông tin dự kiến ​​sẽ các cuộc tấn công vào các máy chủ dễ bị tấn công sẽ gia tăng đáng kể  trong những ngày tới.


Phiên bản nào của thư viện Log4j dễ bị tấn công và cách để bạn bảo vệ Server?

Hầu như tất cả các phiên bản của Log4j đều dễ bị tấn công, bắt đầu từ 2.0-beta9 đến 2.14.1. Phương pháp bảo vệ đơn giản và hiệu quả nhất là cài đặt phiên bản mới nhất của thư viện, 2.15.0. Bạn có thể tải xuống trên trang dự án.

Nếu vì lý do nào đó mà việc cập nhật thư viện không thể thực hiện được, Apache Foundation khuyên bạn nên sử dụng một trong các phương pháp giảm thiểu sau. Trong trường hợp các phiên bản Log4J từ 2.10 đến 2.14.1, họ khuyên bạn nên đặt thuộc tính hệ thống log4j2.formatMsgNoLookups hoặc đặt biến môi trường LOG4J_FORMAT_MSG_NO_LOOKUPS thành true.

Để bảo vệ các bản phát hành trước đó của Log4j (từ 2.0-beta9 đến 2.10.0), các nhà phát triển thư viện khuyên bạn nên xóa class JndiLookup khỏi classpath: zip -q -d log4j-core – *. Jar org / apache / logging / log4j / core / lookup / JndiLookup .class.

Ngoài ra, bạn cũng nên xem những phương pháp bảo mật này để bảo vệ bản thân tốt hơn.
