Title: Hotmail Javascript STYLE Vulnerability
Severity: HIGH
Description:
The HTML STYLE command can be used to embed Javascript into Hotmail email messages. The STYLE tag circumvents current methods employed by Hotmail to disable Javascript from email messages. When viewed by a Microsoft IE 5.0 or Netscape Navigator 4.X browser, the Javascript in the email may execute various commands on the viewer's mailbox. The commands could take various actions on the user's inbox, including: reading email, deleting email, or prompting users to re-enter their password in a trojan application.
