An adversary with this knowledge may look for vulnerabilities particular to the version 9.four.8 of Jetty. This header contains details about the backend server (type and version). When the person clicks on the malicious software (ex. a web-based game), the clicks might be ‘stolen’ and despatched to the goal application (Clickjacking). If Access-Control-Allow-Origin is weakly configured, an attacker can read the information from the goal website by using another third-party web site.

The Content-Security-Policy header is an improved version of the X-XSS-Protection header and offers an extra layer of safety. This is as a end result of an attacker could intercept HTTP connections and inject the header or take away it.
