Cross-Site Tracing (XST)
Cross-Site Tracing (XST) is a vulnerability that can affect websites and web applications. It is a type of cross-site scripting (XSS) attack that involves exploiting the HTTP TRACE method, which is used for debugging and testing purposes.
In simple terms, XST occurs when an attacker sends malicious code to a website or web application, which then uses the HTTP TRACE method to “trace” the attacker’s code back to the original source. This can give the attacker access to sensitive information, such as cookies, authentication credentials, and other personal data.
To prevent XST attacks, website and web application developers can disable the HTTP TRACE method, or use other security measures such as input validation and output encoding. It is also important for users to be cautious when browsing the internet and to use strong, unique passwords for each website or account.
Overall, XST is a serious security concern for websites and web applications, and it is important for developers and users to take steps to protect themselves against this type of attack.
