Dù vậy, đây là một lỗ hổng một khi đã xuất hiện thì đều được đánh giá ở mức độ nghiêm trọng. An XML External Entity (XXE) attack (sometimes called an XXE injection attack) is a type of attack that abuses a widely available but rarely used feature of XML parsers. Using XXE, an attacker is able to cause Denial of Service (DoS) as well as access local and remote content and services.

XML external entity injection (XXE) is an attack where untrusted data is provided to a misconfigured XML parser. XML structures data by using tags, and provides a rigid schema mechanism that describes the nesting, presence, and type of tags. For example, XML is used in communicating data between client and server, or to locally serialize and .Discover the fundamentals of XML and gain insights into the potential risks of XML External Entity (XXE) injection. Explore why XXE vulnerabilities occur, how they can be exploited, and learn effective strategies to prevent them. Whether you're new to XML or well-versed in its concepts, this article offers a comprehensive understanding of XXE and its prevention . XXE (XML External Entity Injection) is a web-based vulnerability that enables a malicious actor to interfere with XML data processes in a web application. It often enables visibility of the files on an application server’s file system and interacts with a backend or external system that the application itself has access to. An XML eXternal Entity injection (XXE) is an attack against applications that parse XML input. An XXE attack occurs when untrusted XML input with a reference to an external entity is processed by a weakly configured XML parser. This attack can be used to stage multiple incidents, including denial of service, file system access, or data .

XXE（XML External Entity: XML 外部エンティティ参照, XML 外部実体） は、アプリケーションが XML を解析した際に、XML の特殊構文を悪用されて発生する脆弱性です。 この脆弱性は、DoS やディレクトリトラバーサル（パストラバーサル）、SSRF（Server Side Request Forgery / サーバサイドリクエストフォー .XML外部実体攻撃 (XML External Entity, XXE攻撃) [1] [2] はコンピュータセキュリティにおける脆弱性の一種で、一般にアプリケーションでみられる。 XXEによって攻撃者はネットワークに接続されたサーバー内の通常保護されているはずのファイルを取得することが可能となる。

xml external entity injection2. Giới thiệu lỗ hổng XML external entity (XXE) injection. Ngôn ngữ XML giúp truyền tải và mô tả các loại dữ liệu thuộc nhiều ngôn ngữ lập trình khác nhau, giúp việc chia sẻ các dữ liệu giữa nhiều nền tảng cũng như hệ thống qua Internet trở nên cực kỳ đơn giản.

XML external entity injection (also known as XXE) is a web security vulnerability that allows an attacker to interfere with an application's processing of XML data. It often allows an attacker to view files on the application server filesystem, and to interact with any backend or external systems that the application itself can access. .xml external entity injection XML external entity injection XML is a markup language that we use to define and categorize data. Data stored in XML format can move between multiple servers or between a client and a server. Once a server receives an XML input, it parses it via an XML parser. XML external entities are basically references in the XML document to files or URLs outside of the XML . XXE injection attacks exploit support for XML external entities and are used against web applications that process XML inputs. Attackers can supply XML files with specially crafted DOCTYPE definitions to perform attacks including denial of service, server-side request forgery (SSRF), or even remote code execution. XXE injection is a type of web security vulnerability that allows an attacker to interfere with the way an application processes XML data. Successful exploitation allows an attacker to view files. In this article, we will have an in-depth look at how to find and exploit XML External Entity Injection vulnerabilities. XXE (XML External Entity) as the name suggests, is a type of attack relevant to the applications parsing XML data. As per the XML standard specification, an entity can be considered as a type of storage.* Patch or upgrade all XML processors and libraries in use by the application or on the underlying operating system. Use dependency checkers. Update SOAP to SOAP 1.2 or higher. * Disable XML external entity and DTD processing in all XML parsers in the application, as per the OWASP Cheat Sheet ‘XXE Prevention’.

Sometimes, XXE attacks using regular entities are blocked, due to some input validation by the application or some hardening of the XML parser that is being used. In this situation, you might be able to use XML parameter entities instead. XML parameter entities are a special kind of XML entity which can only be referenced elsewhere within the DTD. XML External Entity Injection is one of the most common vulnerabilities. At its core, it’s a web security vulnerability where attackers target and compromise an application’s processing of XML data. However, what makes XXE attacks so powerful is that they can be deployed against various programming languages, including C/C++, Java, .
