11系统中编号为CVE-2025-9491的LNK文件高危漏洞。该漏洞最早可追溯至2025年3月，于2025年8月底被公开披露，可被利用实现远程任意代码执行。微软最初表示该问题不符合其安全漏洞标准，拒绝发布官方补丁。漏洞由趋势科技安全研究人员发现，攻击者可构造特殊.LNK（快捷方式）文件，隐藏内含的恶意指令，使用户在通过Windows界面检查时难以察觉风险。当用户被诱导访问恶意页面或打开此类伪装文件后，恶意代码将在当前系统权限下执行。该漏洞被零日计划（ZDI）评为CVSS 7.0分，属高危级别。2025年11月1日，微软发布声明称已注意到该问题，但认为系统在处理.LNK文件时会多次向用户发出警告，且Microsoft Defender与智能应用控制（Smart App Control）功能足以检测并阻止威胁，因此不构成需修补的安全漏洞。微软当时建议用户避免下载未知来源文件作为主要防御手段。此决定引发部分安全社区讨论。在微软拒绝提供补丁后，安全公司ACROS Security为其0patch平台开发并发布了微补丁，主动拦截相关攻击行为，为用户提供临时防护。第三方安全社区的持续关注和响应可能促使微软重新评估风险。目前微软已通过更新解决恶意指令隐藏问题，完成漏洞修复。","kind":"news","is_publish_news":true,"is_publish_highlight":false,"is_publish_live":false,"is_publish_wemedia":null,"editions":null,"column":"","sentiment":"0","news_tag":"","news_rank":0,"symbols":[],"gpt_button":0,"need_auth":false,"code":"91000000","status":"200"},"commentList":[],"isCommentEnd":true,"newsSizeData":{"likeSize":0,"commentSize":0,"repostSize":0,"favoriteSize":0,"likeStatus":false,"favoriteStatus":false},"APP":{"userAgent":"Mozilla/5.0
