Why CSP Scanner: Notices can be dangerous
Content Security Policy (CSP) adds a layer of security which helps to detect and mitigate certain types of attacks such as Cross Site Scripting (XSS) and data injection attacks. Hackers use XSS attacks to trick trusted websites into delivering malicious content. The browser executes all code from trusted origin and can’t differentiate between legitimate and malicious code, so any injected code is executed as well.
How to fix CSP Scanner: Notices
Review all the notices detected by ScanRepeat and ensure that your web server, application server, load balancer, etc. is properly configured to set the correct Content-Security-Policy header.
How does ScanRepeat report CSP Scanner: Notices
ScanRepeat analyzes every HTTP response ‘Content-Security-Policy’ header and checks its correctness against CSP specification. ScanRepeat notices every duplicate in the ‘Content-Security-Policy’ header and informs about any deprecated or experimental directives being used.
