You really should allow users to input as little HTML and/or javascript as possible. One good solution to validating and sanitizing this stuff is to use a ready-made library like OWASP AntiSamy . Also, take a look at OWASP Enterprise Security API for a collection of security methods that a developer needs to build a secure web application DOMPurify removes any script HTML elements and its content. If you must do input sanitizing. Again, sanitizing really depends on the context of the data. There are cases where sanitizing input is a must. To sanitize the users input data you can still use validator.js as I demonstrated above Java Escape HTML - Encode String to HTML Example Java examples to escape the characters in a String using HTML entities.

  2. sanitizeLoggerNamePart(String name) sanitize Logger Name Part return name.replace('.', '_'); String: sanitizeMethodName(String methodName) Sanitizes a potential method name so it is both valid and follows Java conventions (camel-cased, no underscores, etc.)
  3. The jsoup whitelist sanitizer works by parsing the input HTML (in a safe, sand-boxed environment), and then iterating through the parse tree and only allowing known-safe tags and attributes (and values) through into the cleaned output. It does not use regular expressions, which are inappropriate for this task
  4. Otherwise, download prebuilt jars or git clone git@github.com:OWASP/java-html-sanitizer.git and build the latest source. Unless maven is managing your CLASSPATH for you, you need to add both owasp-java-html-sanitizer.jar and the Guava JAR.

The OWASP JSON Sanitizer Project is a simple to use Java library that can be attached at either end of a data-pipeline to help satisfy Postel's principle: be conservative in what you do, be liberal in what you accept from others In Java (and.NET), sanitization can be achieved by using the OWASP Java HTML Sanitizer Project. In.NET, a number of sanitizers use the Html Agility Pack, an HTML parser. In JavaScript there are JS-only sanitizers for the back end, and browser-based implementations that use browser's own DOM parser to parse the HTML (for better performance) In the tutorial we are going to parse HTML data from a HTML string, local HTML file, and a web page. We are going to sanitize data and perform a Google search. JSoup. JSoup is a Java library for extracting and manipulating HTML data.

DOMPurify works with a secure default, but offers a lot of configurability and hooks. Demo: js-xss. 6.0 6.3 HTML Sanitize untrusted HTML (to prevent XSS) with a. Define a custom validation constraint to do the actual safety check, we can leverage the OWASP Java HTML Sanitizer. The sanitizer will sanitize the string, and the validation check will just be to see that the sanitized version is the same as the original version (thus showing that it does not contain content against your security policy). Apply the validation annotation to the Entity's. let clean = DOMPurify.sanitize( dirty , {USE_PROFILES: {html: true}} ); Is there any foot-gun potential? Well, please note, if you first sanitize HTML and then modify it afterwards, you might easily void the effects of sanitization. If you feed the sanitized markup to another library after sanitization, please be certain that the library doesn't mess around with the HTML on its own. Okay.

For example, do not include exception stack traces inside HTML comments. Guideline 2-2 / CONFIDENTIAL-2: Do not log highly sensitive information . Some information, such as Social Security numbers (SSNs) and passwords, is highly sensitive. This information should not be kept for longer than necessary nor where it may be seen, even by administrators. For instance, it should not be sent to log. Escapes the characters in a String using Java String rules. Deals correctly with quotes and control-chars (tab, backslash, cr, ff, etc.) So a tab becomes the characters '\\' and 't'. The only difference between Java strings and JavaScript strings is that in JavaScript, a single quote must be escaped.

He had been told that it's insecure and to never use it. Today, let's unpack that and learn how to prevent XSS attacks with innerHTML Nothing beats good validation but then make sure to sanitize the value if it fails before redisplaying it. While you can call yourself the method to sanitize the received parameters, you should consider installing this process into a Java EE filter so the container will automatically do it for you

AntiSamy is a Java component that can sanitize HTML/CSS to eliminate potentially malicious JavaScript. Technically, it is an API for ensuring user-supplied HTML/CSS is in compliance within an application's rules. Another way of saying that could be: It's an API that helps you make sure that clients don't supply malicious cargo code in the HTML they supply for their profile, comments.

It's always a good idea to sanitize the input before sending it to the database. Parameterized queries might save you from SQL injection attacks, but might not prove beneficial in case of stored XSS attacks.
