Multiple Mozilla products JavaScript URL redirect information disclosure

mozilla-javascripturl-infor-disclosure (47413) The risk level is classified as LowLow Risk


Multiple Mozilla products, including Firefox, Thunderbird and SeaMonkey could allow a remote attacker to bypass cross-domain security restrictions, caused by an error when processing JavaScript URLs redirecting the browser to an off-domain target that returns non-JavaScript data. By persuading a victim to visit a specially-crafted Web site, a remote attacker could bypass same-origin policy restrictions using the window.onerror DOM API to gain unauthorized access to other domains and obtain sensitive information from the system.
