谷歌Chrome浏览器以及基于Chromium的浏览器中存在“重大”问题

谷歌Chrome网络浏览器以及基于Chromium的浏览器中存在“重大”问题,可能允许恶意网页自动覆盖剪贴板内容,只要访问网站,无需任何用户许可或交互。

据开发人员 Jeff Johnson 称,剪贴板中毒攻击是在 Chrome 104版本中意外出现。

虽然 Apple Safari 和 Mozilla Firefox 中也存在该问题,但在 Chrome 中使问题变得严重的原因在于,使用用户手势复制内容到剪贴板的方式已经被攻破,其中包括选择一段文本按住“Ctrl +C”复制或在右键下拉列表中选择复制。

这种可以替换剪贴板数据的能力会带来安全隐患。在一个假设的攻击场景中,攻击者可能会引诱受害者访问恶意登录页面,并重写受害者先前复制的加密货币钱包的地址,从而导致未经授权的资金转移。或者,攻击者可以用特制的网站连接覆盖剪贴板内容,导致受害者下载危险软件。

“当您浏览网页是,该页面可能在您不知情的情况下,擦除当前可能对您有价值的系统剪贴板内容,然后用恶意页面需要的任何内容替换它,下一次粘贴时,替换的恶意内容可能给你带来危险。”Johnson道。

目前,谷歌已经发布了适用于 Windows、macOS 和 Linux 的新版 Chrome (105.0.5195.52/53/54),修复了 24 个缺陷,其中 10 个与网络服务、WebSQL、 WebSQL、PhoneHub 等应用中的释放后使用错误有关。如果你正在使用Chrome浏览器,请确保你已经更新到最新版本。
