<h2>Tính năng</h2>
<ul>
<li>Hỗ trợ danh sách các URL.</li>
<li><a href="https://viblo.asia/p/tim-hieu-ve-fuzz-testing-YWOZrDzv5Q0" target="_blank" rel="noopener">Fuzzing</a> cho hơn 60 request headers HTTP (không chỉ 3-4 headers như các công cụ đã thấy trước đây).</li>

<h2>Miêu tả</h2>
<p>Tác giả đã nghiên cứu Log4J RCE (CVE-2021-44228) kể từ khi nó được phát hiện và đã làm việc để ngăn chặn lỗ hổng bảo mật này. Team đã phát triển một công cụ quét mã nguồn mở để phát hiện và và giúp các nhà phát triển vá lỗ hổng Log4J RCE CVE-2021-44228. Công cụ này sẽ được sử dụng bởi các nhóm bảo mật nhằm quét cơ sở hạ tầng của họ để tìm Log4J RCE và cũng kiểm tra các lượt bypass WAF có thể dẫn đến việc thực thi mã trên môi trường dự án.<br />
Nó hỗ trợ callback DNS OOB ngay lập tức, không cần thiết lập máy chủ callback DNS.</p>

										<content:encoded><![CDATA[<p>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.</p>
<p><img decoding="async" class="aligncenter  size-full" src="https://anonyviet.com/wp-content/uploads/2021/12/Log4j-blog-post.jpg" alt="Lỗ hổng nghiêm trọng trong thư viện Apache Log4j" width="1000" height="650" title="Cách sửa lỗi bảo mật Log4j nếu bạn không thể Update lên 2.15.0 4"></p>
<p>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 <a href="https://logging.apache.org/log4j/2.x/security.html" rel="noopener">tại đây</a>.</p>
<h2>Tại sao CVE-2021-44228 lại nguy hiểm đến vậy</h2>
<p>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.</p>
<p>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.</p>
<p>Cách bài viết hướng dẫn tấn công <a href="https://tophuongloan.com/poc-la-gi/" rel="noopener">Proofs of Concept (PoC)</a> 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.</p>
<p>Lỗ hổng này được phát hiện bởi Chen Zhaojun thuộc Đội bảo mật đám mây của Alibaba.</p>
<h2>Apache Log4J là gì và tại sao thư viện này lại phổ biến như vậy?</h2>
<p>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.</p>
<p>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,&#8230; 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.</p>

<h2>Phiên bản nào của thư viện Log4j dễ bị tấn công và cách để bạn bảo vệ Server?</h2>
<p>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<a href="https://logging.apache.org/log4j/2.x/download.html" rel="noopener"> dự án</a>.</p>
<p>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 <strong>log4j2.formatMsgNoLookups</strong> hoặc đặt biến môi trường <strong>LOG4J_FORMAT_MSG_NO_LOOKUPS</strong> thành <strong>true</strong>.</p>
<p>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: <strong>zip -q -d log4j-core – *. Jar org / apache / logging / log4j / core / lookup / JndiLookup .class</strong>.</p>
<p>Ngoài ra, bạn cũng nên xem <a href="https://anonyviet.com/phuong-phap-bao-mat-giup-an-toan-tren-internet/">những phương pháp bảo mật này để bảo vệ bản thân tốt hơn</a>.</p>

										<content:encoded><![CDATA[<p><strong>Vào ngày 9 tháng 12 năm 2021, một lỗ hổng thực thi mã từ xa (RCE) trong Apache log4j 2được xác định và được định danh bằng mã CVE-2021-44228. Bằng chứng khai thác (PoC) công khai đã được phát hành và cho thấy việc khai thác cực kỳ dễ thực hiện. Bằng cách gửi một yêu cầu độc hại đến một hệ thống bị lỗ hổng Log4j kẻ tấn công có thể điều khiển hệ thống đó tải xuống và sau đó thực thi mã độc. Do việc khai thác này mới được phát hiện gần đây, nên vẫn còn nhiều Server kể cả vật lý hay môi trường Cloud, vẫn chưa được vá. Giống như nhiều vụ khai thác RCE có mức độ nghiêm trọng cao, cho đến nay, hoạt động scan quy mô lớn của Hacker đã bắt đầu trên internet với mục đích tìm kiếm và khai thác các hệ thống chưa được vá. Để khắc phục lỗ hổng từ Log4j, bạn cần nâng cấp lên phiên bản mới nhất Apache log4j 2 (2.15.0-rc2) cho tất cả các hệ thống.</strong></p>
<p><a href="https://anonyviet.com/wp-content/uploads/2021/12/lo-hong-log4j.jpg"><img decoding="async" class="aligncenter size-full " src="https://anonyviet.com/wp-content/uploads/2021/12/lo-hong-log4j.jpg" alt="lo hong log4j" width="572" height="384" title="Lỗ hổng Log4j nguy hiểm đến mức nào 6"></a></p>
<p class="paywall">Log4j là một thư viện Java và mặc dù ngôn ngữ lập trình ngày nay ít phổ biến hơn với người tiêu dùng, nhưng nó vẫn được sử dụng rất rộng rãi trong các hệ thống doanh nghiệp và ứng dụng web.</p>
<p>Hiện nay hầu như các ứng dụng Java đều sử dụng thư viện Log4j. Log4j được phát triển bởi Apache Foundation và được sử dụng rộng rãi bởi cả ứng dụng dành cho doanh nghiệp và dịch vụ đám mây.</p>
<p>Các ứng dụng web và sản phẩm từ Apple, Amazon, Cloudflare, Twitter và Steam đều có khả năng bị tấn công RCE nhắm vào mục tiêu này tính dễ đang dính lỗ hổng bảo mật này.</p>
<h2>Phiên bản Apache Log4j bị ảnh hưởng</h2>
<p>Apache Log4j 2.x &lt;= 2.15.0-rc1</p>
<h2>Phần mềm bị ảnh hưởng</h2>
<p>Apache log4j 2 là một module ghi nhật ký dựa trên Java mã nguồn mở, được sử dụng trong nhiều ứng dụng Java trên khắp thế giới. So với bản phát hành log4j 1.X ban đầu, log4j 2 đã giải quyết các vấn đề với bản phát hành trước đó và cung cấp kiến ​​trúc plugin cho người dùng. Vào ngày 5 tháng 8 năm 2015, log4j 2 đã trở thành phiên bản chính và tất cả người dùng log4j phiên bản trước được khuyến nghị nâng cấp lên log4j 2. Apache log4j 2 được sử dụng rộng rãi trong nhiều ứng dụng phần mềm phổ biến, chẳng hạn như Apache Struts, ElasticSearch, Redis, Kafka và những người khác.</p>
<p>Một số lượng đáng kể các ứng dụng dựa trên Java đang sử dụng log4j làm tiện ích ghi nhật ký và rất dễ bị tấn công bởi CVE này. Theo thống kê, ít nhất phần mềm sau có thể bị ảnh hưởng:</p>
<ul>
<li>Apache Struts</li>
<li>Apache Solr</li>
<li>Apache Druid</li>
<li>Apache Flink</li>
<li>ElasticSearch</li>
<li>Flume</li>
<li>Apache Dubbo</li>
<li>Logstash</li>
<li>Kafka</li>
<li>Spring-Boot-starter-log4j2</li>
</ul>
