Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

Electron 是一个用于使用 JavaScript、HTML 和 CSS 开发跨平台桌面应用程序的框架。在版本 42.11.16、43.8.1、44.9.1 和 45.0.0-beta.6 之前，Electron 未能在 Chromium 网络模块、Node.js 的 tls、https 或 fetch 模块中阻止由 eMudhra 签发的受 compromises 的中间证书。若攻击者持有由这些中间证书签发的证书，并能够拦截网络流量，则可对受影响的应用程序伪装成 TLS 服务器。该问题已在版本 42.11.1

Vulnerability Title
Electron: Mitigation for compromised eMudhra intermediate certificates
Source: CVE Program / CVE List V5
Vulnerability Description
Electron is a framework for writing cross-platform desktop applications using JavaScript, HTML and CSS. Prior to 42.11.16, 43.8.1, 44.9.1, and 45.0.0-beta.6, Electron does not block compromised eMudhra intermediate certificates in Chromium networking, Node.js tls, Node.js https, or Node.js fetch. An attacker who holds a certificate issued through one of these intermediates and can intercept network traffic can impersonate a TLS server to an affected application. This issue is fixed in versions 42.11.16, 43.8.1, 44.9.1, and 45.0.0-beta.6.
