This type of injection allows an attacker to inject arbitrary code in another web application’s user session through the manipulation of request parameters. The most common vectors of XSS involve injecting user-controlled data via HTTP GET requests into vulnerable web applications via user-supplied data in the browser’s address bar. The attacker can then use injection techniques such as DOM or SQL to manipulate the data in the target application’s database. Such attacks can be especially dangerous because they often exploit user trust and lack of input validation. When an attacker has access to user credentials, they can gain full access to the affected application and its data. This can easily lead to the attacker gaining access to sensitive information such as user email addresses or personal data. XSS is one of the most common vulnerability types and can be found in many different types of software, as it is very easy to exploit. XSS can lead to information leakage, theft of user credentials, and even the installation of malware on the targeted system.
Stored XSS
A stored XSS occurs when attackers store malicious or exploitative code in a web application and use it to launch attacks at a later date. This type of injection allows an attacker to execute their attack code after the victim visits their web site. Stored XSS is one of the most common types of XSS attacks because they allow attackers to maintain persistence on their target system and avoid detection. Stored XSS exploits typically exploit vulnerabilities in software that store data for subsequent retrieval, such as a database management system or cache.
XSS Testing Framework
If you have a web application, there is a good chance it has been affected by XSS. In fact, it is estimated that nearly 60% of all websites are vulnerable to this type of injection. Fortunately, there are many ways in which to test for this vulnerability. A common approach is to use a framework such as the OWASP XSS Testing Framework [1]. This framework provides a set of tests that can be easily implemented into automated testing tools or manual testing approaches. This framework helps identify if an application is vulnerable and how severe the vulnerability is. There are also many third-party frameworks such as Burp Suite that can help identify vulnerabilities [2].
Other important considerations with XSS include the existence of privilege escalation vulnerabilities, such as SQL injection or command injection; and whether or not your application supports HTML5 placeholder mitigation techniques and Content Security Policy (CSP).

HTML Injection
HTML Injection is a web application vulnerability that allows an attacker to inject HTML via the URL. The most common vector of this attack is by sending data through the browser’s address bar and then exploiting it in the target application. For example, an attacker could inject JavaScript code into a web application that would be executed when a user visits the page. This can often lead to information leakage, theft of user credentials, and even the installation of malware on the targeted system.
