Prevention strategies for DOM-based XSS attacks include very similar measures to traditional XSS prevention strategies but implemented in JavaScript code and contained in web pages (i.e. input validation and escaping). [17] Some JavaScript frameworks have built-in countermeasures against this and other types of attack — for example AngularJS ...
Content Security Policy (CSP) is a computer security standard introduced to prevent cross-site scripting (XSS), clickjacking and other code injection attacks resulting from execution of malicious content in the trusted web page context. [1]
XSS worms exploit a security vulnerability known as cross site scripting (or XSS for short) within a website, infecting users in a variety of ways depending on the vulnerability. Such site features as profiles and chat systems can be affected by XSS worms when implemented improperly or without regard to security. Often, these worms are specific ...
In PHP, HTML sanitization can be performed using the strip_tags() function at the risk of removing all textual content following an unclosed less-than symbol or angle bracket. [2] The HTML Purifier library is another popular option for PHP applications. [3] In Java (and .NET), sanitization can be achieved by using the OWASP Java HTML Sanitizer ...
Cross-site leaks allow an attacker to access a user's interactions with other websites. This can contain sensitive information. Web browsers normally stop other websites from seeing this information. This is enforced through a set of rules called the same-origin policy. Attackers can sometimes get around these rules, using a "cross-site leak".
Header injection in HTTP responses can allow for HTTP response splitting, session fixation via the Set-Cookie header, cross-site scripting (XSS), and malicious redirect attacks via the location header.
This code can allow the attacker to impersonate another user. However, this same software bug can be accidentally triggered by an unassuming user, which will cause the website to display bad HTML code. HTML and script injection are popular subjects, commonly termed "cross-site scripting" or "XSS". XSS refers to an injection flaw whereby user ...
HTTP response splitting is a form of web application vulnerability, resulting from the failure of the application or its environment to properly sanitize input values.It can be used to perform cross-site scripting attacks, cross-user defacement, web cache poisoning, and similar exploits.
