CVE-2022-36070— Poetry's Untrusted Search Path can lead to Local Code Execution on Windows

Quick assessment

Affected
python-poetry poetry
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

Poetry是Python 中用于依赖管理和打包的工具。它允许您声明项目所依赖的库，并将为您管理（安装/更新）它们。 Poetry 1.1.9之前版本和1.2.0b1之前版本存在代码问题漏洞，该漏洞源于执行各种命令是使用可执行文件的名称而不是其绝对路径执行的，由于Windows将可执行文件名称解析为路径的方式，这可能导致执行不受信任的代码。如果开发人员被利用，攻击者可以窃取凭据或保留其访问权限，如果漏洞发生在服务器上，攻击者可以使用他们的访问权限来攻击其他内部系统。

Vulnerability Title
Poetry's Untrusted Search Path can lead to Local Code Execution on Windows
Source: CVE Program / CVE List V5
Vulnerability Description
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.
