A cross-domain vulnerability in Firefox 3.x before 3.0.6 allows bypass of Same Origin Policy via a chrome XBL method and window.eval, enabling XSS attacks.

Vulnerability

A cross-domain vulnerability exists in js/src/jsobj.cpp in Mozilla Firefox 3.x before 3.0.6. The issue allows remote attackers to bypass the Same Origin Policy by using a chrome XBL method in conjunction with window.eval. Firefox 2 is not affected [3][4].

Exploitation

An attacker can craft a malicious web page that invokes a chrome XBL method and window.eval to execute arbitrary JavaScript in the context of another website, violating the same origin policy. No additional authentication or user interaction beyond visiting the page is required [3][4].

Impact

Successful exploitation enables cross-site scripting (XSS) attacks, allowing the attacker to access properties of an arbitrary window and potentially steal sensitive information from the target site. The impact is rated as high [4].

Mitigation

The vulnerability is fixed in Firefox 3.0.6, released on February 3, 2009. Users should update to this version or later. As a workaround, disabling JavaScript until the update is applied can mitigate the risk [1][4]. If no fix is available, follow the vendor's instructions.
