If malicious content is injected into an application that escapes special characters and that malicious content uses as HTML tags, those characters are nonetheless not interpreted as HTML tags by the browser if they’ve been correctly escaped in the application code and in this way the attempted attack is diverted. There are a few methods by which XSS can be manipulated: Type The most prominent use of XSS is to steal cookies (source: OWASP HttpOnly) and hijack user sessions, but XSS exploits have been used to expose sensitive information, enable access to privileged services and functionality and deliver malware. The malicious code is inserted in the application (usually as a link) by the attacker. ![]() The code is activated every time a user clicks the link. The attacker delivers a malicious link externally from the vulnerable web site application to a user. When clicked, malicious code is sent to the vulnerable web site, which reflects the attack back to the user’s browser. The attacker forces the user’s browser to render a malicious page. The data in the page itself delivers the cross-site scripting data. The attacker injects code that appears safe, but is then rewritten and modified by the browser, while parsing the markup. NET Framework team also releases features out of band, using NuGet, to expand platform support and introduce new functionality, such as immutable collections and SIMD-enabled vector types.This section describes the top best practices designed to specifically protect your code: The following environments are susceptible to an XSS attack: An example is rebalancing unclosed quotation marks or even adding quotation marks to unquoted parameters. For more information, see Additional Class Libraries and APIs and. See a complete list of NuGet packages for. NET Framework 4.8 builds on previous versions of. NET Framework 4.8 from the following locations: NET Framework 4.x by adding many new fixes and several new features while remaining a very stable product. NET Framework 4.8 can be installed on Windows 10, Windows 8.1, Windows 7 SP1, and the corresponding server platforms starting with Windows Server 2008 R2 SP1. NET Framework 4.8 by using either the web installer or the offline installer. The recommended way for most users is to use the web installer. NET Framework 4.8 introduces new features in the following areas: NET Framework 4.8 in Visual Studio 2012 or later by installing the. Improved accessibility, which allows an application to provide an appropriate experience for users of Assistive Technology, continues to be a major focus of. For information on accessibility improvements in. NET Framework 4.8, see What's new in accessibility in. NET Framework, managed cryptographic provider classes such as SHA256Managed throw a CryptographicException when the system cryptographic libraries are configured in "FIPS mode". These exceptions are thrown because the managed versions of the cryptographic provider classes, unlike the system cryptographic libraries, have not undergone FIPS (Federal Information Processing Standards) 140-2 certification. NET Framework 4.8, the following managed cryptography classes no longer throw a CryptographicException in this case: Because few developers have their development machines in FIPS mode, the exceptions are commonly thrown in production systems.īy default in applications that target. Instead, these classes redirect cryptographic operations to a system cryptography library. This change effectively removes a potentially confusing difference between developer environments and production environments and makes native components and managed components operate under the same cryptographic policy. Applications that depend on these exceptions can restore the previous behavior by setting the AppContext switch. For more information, see Managed cryptography classes do not throw a CryptographyException in FIPS mode. NET Framework 4.5, the clrcompression.dll assembly uses ZLib, a native external library for data compression, in order to provide an implementation for the deflate algorithm. NET Framework 4.8 version of clrcompression.dll is updated to use ZLib Version 1.2.11, which includes several key improvements and fixes.
