Mozilla Firefox and SeaMonkey data: URL cross-site scripting

mozilla-dataurl-xss (32667) The risk level is classified as MediumMedium Risk

Description:

Mozilla Firefox and SeaMonkey could allow a remote attacker to bypass cross-site scripting protection and perform cross-site scripting attacks on vulnerable Web applications, caused by improper validation of user-supplied input by the browser.js script. A remote attacker could exploit this vulnerability by creating a specially-crafted javascript: URL popup containing the same data: URL as the victim's browser to inject malicious script into a Web page which would be executed in a victim's Web browser within the security context of the hosting Web site, once the popup is enabled and the page is viewed. An attacker could use this vulnerability to steal the victim's cookie-based authentication credentials.
