When resolving a program, Python/Windows look for the current working directory, and after that the PATH environment. GitPython defaults to use the `git` command, if a user runs GitPython from a repo has a `git.exe` or `git` executable, that program will be run instead of the one in the user's `PATH`. This is more of a problem on how Python interacts with Windows systems, Linux and any other OS aren't affected by this. But probably people using GitPython usually run it from the CWD of a repo. An attacker can trick a user to download a repository with a malicious `git` executable, if the user runs/imports GitPython from that directory, it allows the attacker to run any arbitrary commands. There is no fix currently available for windows users, however there are a few mitigations. 1: Default to an absolute path for the git program on Windows, like `C:\\\\Program Files\\\\Git\\\\cmd\\\\git.EXE` (default git path installation). 2: Require users to set the `GIT_PYTHON_GIT_EXECUTABLE` environment variable on Windows systems. 3: Make this problem prominent in the documentation and advise users to never run GitPython from an untrusted repo, or set the `GIT_PYTHON_GIT_EXECUTABLE` env var to an absolute path. 4: Resolve the executable manually by only looking into the `PATH` environment variable."}],"source":{"advisory":"GHSA-wfm5-v35h-vwf4","discovery":"UNKNOWN"}},"adp":[{"providerMetadata":{"orgId":"af854a3a-2127-422b-91ae-364da2661108","shortName":"CVE","dateUpdated":"2024-08-02T18:38:50.996Z"},"title":"CVE Program Container","references":[{"name":"https://github.com/gitpython-developers/GitPython/security/advisories/GHSA-wfm5-v35h-vwf4","tags":["x_refsource_CONFIRM","x_transferred"],"url":"https://github.com/gitpython-developers/GitPython/security/advisories/GHSA-wfm5-v35h-vwf4"},{"name":"https://docs.python.org/3/library/subprocess.html#popen-constructor","tags":["x_refsource_MISC","x_transferred"],"url":"https://docs.python.org/3/library/subprocess.html#popen-constructor"}]},{"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2024-10-02T14:04:30.245441Z","id":"CVE-2023-40590","options":[{"Exploitation":"poc"},{"Automatable":"no"},{"Technical Impact":"total"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2024-10-02T14:04:39.463Z"}}]}}
