CVE-2020-26275— Jupyter Server 输入验证错误漏洞

Open redirect vulnerability

The Jupyter Server provides the backend (i.e. the core services, APIs, and REST endpoints) for Jupyter web applications like Jupyter notebook, JupyterLab, and Voila. In Jupyter Server before version 1.1.1, an open redirect vulnerability could cause the jupyter server to redirect the browser to a different malicious website. All jupyter servers running without a base_url prefix are technically affected, however, these maliciously crafted links can only be reasonably made for known jupyter server hosts. A link to your jupyter server may *appear* safe, but ultimately redirect to a spoofed server on the public internet. This same vulnerability was patched in upstream notebook v5.7.8. This is fixed in jupyter_server 1.1.1. If upgrade is not available, a workaround can be to run your server on a url prefix: "jupyter server --ServerApp.base_url=/jupyter/".

指向未可信站点的URL重定向(开放重定向)

Jupyter Server 输入验证错误漏洞

Jupyter Server是Jupyter社区的一款用于为Jupyter Web应用提供后端服务的应用软件。 Jupyter 1.1.1版本之前存在安全漏洞，该漏洞源于一个开放的重定向漏洞可能导致Jupyter服务器将浏览器重定向到另一个恶意网站。所有没有基本url前缀的jupyter服务器在技术上都会受到影响，但是，这些恶意链接只能为已知的jupyter服务器主机提供。一个到木星服务器的链接可能看起来“安全”，但最终会重定向到一个被欺骗的服务器。
