What is CVE-2022-24757?
CVE-2022-24757 is a high-severity vulnerability in jupyter-server jupyter_server, published on 23 Mar 2022. An attacker can exploit it over the internet without logging in, with no action from the victim.
Official description
The Jupyter Server provides the backend (i.e. the core services, APIs, and REST endpoints) for Jupyter web applications. Prior to version 1.15.4, unauthorized actors can access sensitive information from server logs. Anytime a 5xx error is triggered, the auth cookie and other header values are recorded in Jupyter Server logs by default. Considering these logs do not require root access, an attacker can monitor these logs, steal sensitive auth/cookie information, and gain access to the Jupyter server. Jupyter Server version 1.15.4 contains a patch for this issue. There are currently no known workarounds.
Weakness: CWE-532
