DOM-based XSS
DOM-based XSS, also known as Cross-Site Scripting, is a type of security vulnerability found in web applications. This vulnerability allows attackers to inject malicious code into a website, which can then be executed on a user’s browser.
The “DOM” part of the name refers to the Document Object Model, which is a programming interface for HTML and XML documents. This means that the vulnerability occurs within the client-side code of the website, rather than on the server-side.
In other words, a hacker can use this vulnerability to insert their own code into a website, which can then be executed by unsuspecting users who visit that site. This can result in stolen data, like login credentials, or even complete takeovers of user accounts.
To prevent this type of attack, developers should make sure to sanitize user input, validate all requests made to the site, and use secure coding practices. It’s also important for users to be aware of the risks of clicking on suspicious links or entering personal information on untrusted websites.
