Описание
Dulwich is a pure-Python implementation of the Git file formats and protocols. Starting in version 0.23.2 and prior to version 1.2.5, dulwich.porcelain.submodule_update, and by extension porcelain.clone(..., recurse_submodules=True), materializes attacker-controlled submodule paths from a crafted upstream repository without path validation. A malicious .gitmodules plus a matching tree gitlink whose path is .git/hooks (or any other directory inside the parent repository's .git directory) causes the attacker's submodule tree contents to be written directly into the victim's .git/hooks/ directory, preserving executable mode bits. The dropped executables are then run by any subsequent git or dulwich command that invokes the matching hook, resulting in arbitrary code execution. This is the dulwich equivalent of the upstream Git fixes for CVE-2024-32002 / CVE-2024-32004, which were never propagated into dulwich's separately implemented submodule porcelain. Version 1.2.5 patches the issue.
A flaw was found in Dulwich, a pure-Python implementation of Git file formats and protocols. This vulnerability allows a remote attacker to achieve arbitrary code execution by crafting a malicious Git submodule. When a user clones or updates a repository with such a submodule, the attacker-controlled content is written into the victim's Git hooks directory. Subsequent Git or Dulwich commands can then execute these malicious files, leading to system compromise.
Отчет
Red Hat product security classifies this bug as Important as this bug can be triggered by the victim merely by cloning a maliciours repository. The attacker is however unable to trigger any executable without subsequent actions by the victim. Users should pay attention to any binaries that are cloned over as this is not normal and not clone untrusted repositories. There is no loss of integrity and confidentiality loss can be minimal depending on the due diligence executed by the user so the CVSS score is rated lower even though this bug is classified as Important.
Меры по смягчению последствий
To mitigate this issue, users should avoid cloning or updating Git repositories that contain submodules from untrusted or unverified sources. When interacting with repositories, especially those with submodules, ensure the source is trusted to prevent the execution of arbitrary code via crafted Git hooks. If possible, review the .gitmodules file and the submodule's content before performing recursive submodule operations.
