CVE-2022-36077

Estado: ModificadaMedia (6.1)—

The Electron framework enables writing cross-platform desktop applications using JavaScript, HTML and CSS. In versions prior to 21.0.0-beta.1, 20.0.1, 19.0.11, and 18.3.7, Electron is vulnerable to Exposure of Sensitive Information. When following a redirect, Electron delays a check for redirecting to file:// URLs from other schemes.

Leer descripción completaMostrar menos

The contents of the file is not available to the renderer following the redirect, but if the redirect target is a SMB URL such as `file://some.website.com/`, then in some cases, Windows will connect to that server and attempt NTLM authentication, which can include sending hashed credentials.This issue has been patched in versions: 21.0.0-beta.1, 20.0.1, 19.0.11, and 18.3.7. Users are recommended to upgrade to the latest stable version of Electron. If upgrading isn't possible, this issue can be addressed without upgrading by preventing redirects to file:// URLs in the `WebContents.on('will-redirect')` event, for all WebContents as a workaround.

En versiones anteriores a 21.0.0-beta.1, 20.0.1, 19.0.11 y 18.3.7, Electron es vulnerable a la exposición de información confidencial. Al seguir una redirección, Electron retrasa la verificación de la redirección a file:// URL desde otros esquemas. El contenido del archivo no está disponible para el renderizador después de la redirección, pero si el destino de la redirección es una URL SMB como `file://some.website.com/`, en algunos casos, Windows se conectará a ese servidor e intente la autenticación NTLM, que puede incluir el envío de credenciales hash. Este problema se solucionó en las versiones: 21.0.0-beta.1, 20.0.1, 19.0.11 y 18.3.7. Se recomienda a los usuarios actualizar a la última versión estable de Electron.
