CVE-2022-36070

Poetry is a dependency manager for Python. To handle dependencies that come
from a Git repository, Poetry executes various commands, e.g. git config.
These commands are being executed using the executable’s name and not its
absolute path. This can lead to the execution of untrusted code due to the
way Windows resolves executable names to paths. Unlike Linux-based
operating systems, Windows searches for the executable in the current
directory first and looks in the paths that are defined in the PATH
environment variable afterward. This vulnerability can lead to Arbitrary
Code Execution, which would lead to the takeover of the system. If a
developer is exploited, the attacker could steal credentials or persist
their access. If the exploit happens on a server, the attackers could use
their access to attack other internal systems. Since this vulnerability
requires a fair amount of user interaction, it is not as dangerous as a
remotely exploitable one. However, it still puts developers at risk when
dealing with untrusted files in a way they think is safe. The victim could
also not protect themself by vetting any Git or Poetry config files that
might be present in the directory, because the behavior is undocumented.
Versions 1.1.9 and 1.2.0b1 contain patches for this issue.
