Mozilla Firefox字符编码跨站脚本漏洞
发布日期：2008-03-25
更新日期：2008-05-22
受影响系统：
Mozilla Firefox < 2.0.0.12不受影响系统：
Mozilla Firefox 2.0.0.12描述：
BUGTRAQ ID: 29303
CVE(CAN) ID: CVE-2008-0416
Firefox是一款流行的开源WEB浏览器。
Firefox及其衍生产品中的HTML解析器没有遵循HTML规范，将退格字符处理为空格，这可能在遵循了上述规范过滤输入的网站上导致跨站脚本攻击。此外Firefox没有正确的解析Shift_JIS编码的0x80控制字符，这可能允许攻击者绕过站点输入过滤执行跨站脚本攻击。
