Huge Server Security Exploit Unwittingly Opened By Jupyter Notebook

Huge Server Security Exploit Unwittingly Opened By Jupyter Notebook This document outlines two vulnerabilities in jupyter notebook and jupyterlab, found during an internal security assessment at google. both vulnerabilities are xss leading to an impact of rce (remote code execution). Researchers found 350 internet facing jupyter notebook servers giving unauthenticated access to jupyter’s web user interface & command line shell interface.

Jupyter Notebook Not Loading Properly Skipped Non Installed Server S The researchers add that there are currently more than 200 jupyter notebook deployments connected to the internet without authentication. although it is possible that some of these environments are honeypots, experts foresee that these first attacks are part of a massive exploitation campaign. Tl:dr; all recent jupyterlab and notebook versions are susceptible to a attack where a maliciously crafted notebook can trigger arbitrary code execution when a user views these malicious files. The vulnerability depends on user interaction by opening a malicious notebook with markdown cells, or markdown file using jupyterlab preview feature. a malicious user can access any data that the attacked user has access to as well as perform arbitrary requests acting as the attacked user. I've been using jupyter notebook for about six months now, but i don't really know the inner workings and any potential security issues i should be concerned with.

Jupyter Notebook Extremely Slow Issue 6438 Jupyter Notebook The vulnerability depends on user interaction by opening a malicious notebook with markdown cells, or markdown file using jupyterlab preview feature. a malicious user can access any data that the attacked user has access to as well as perform arbitrary requests acting as the attacked user. I've been using jupyter notebook for about six months now, but i don't really know the inner workings and any potential security issues i should be concerned with. Using the internet connected device search engine shodan, datagravity crafted a search query that can identify jupyter notebook servers that did not have a password set for access to the web interface. If the target machine opens the jupyter notebook server then we can access to it from outside, we can simply execute arbitrary python script in notebook. in short, we can get a shell by reverse shell!. Jupyter notebook uses a deprecated version of google caja to sanitize user inputs. a public caja bypass can be used to trigger an xss when a victim opens a malicious ipynb document in jupyter notebook. the xss allows an attacker to execute arbitrary code on the victim computer using jupyter apis. Today, datagravity has published a detailed report about the vulnerability, including the employed methodology, quantified findings, and recommendations for jupyter notebook server users to.
