CVE-2022-36069— Poetry Argument Injection vulnerability can lead to local Code Execution

Poetry Argument Injection vulnerability can lead to local Code Execution

Poetry is a dependency manager for Python. When handling dependencies that come from a Git repository instead of a registry, Poetry uses various commands, such as `git clone`. These commands are constructed using user input (e.g. the repository URL). When building the commands, Poetry correctly avoids Command Injection vulnerabilities by passing an array of arguments instead of a command string. However, there is the possibility that a user input starts with a dash (`-`) and is therefore treated as an optional argument instead of a positional one. This can lead to Code Execution because some of the commands have options that can be leveraged to run arbitrary executables. 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, because the exploit still works when the victim tries to make sure nothing can happen, e.g. by vetting any Git or Poetry config files that might be present in the directory. Versions 1.1.9 and 1.2.0b1 contain patches for this issue.

对生成代码的控制不恰当(代码注入)

Poetry 参数注入漏洞

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之前版本存在参数注入漏洞，该漏洞源于在构建命令时，用户输入有可能以破折号开头，因此被视为可选参数而不是位置参数，这可能导致代码执行，如果被利用，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。
