CVE-2022-41383

Vulnerability

The d8s-archives package (also known as Democritus Archives) distributed on PyPI includes a potential code-execution backdoor in version 0.1.0. The backdoor is introduced by the democritus-file-system package, which is a dependency that can be replaced by an attacker with a malicious version. The affected version is 0.1.0 [1][2].

Exploitation

An attacker can upload a malicious democritus-file-system package to PyPI with the same name, and when a user installs d8s-archives==0.1.0, the malicious dependency is fetched and executed. No special privileges or network position beyond the ability to publish to PyPI is required for the attacker; the victim only needs to install the vulnerable version [2].

Impact

Successful exploitation allows arbitrary code execution on the victim's system with the privileges of the user installing the package. This can lead to full compromise of the affected environment, including data theft, installation of malware, or further lateral movement [2].

Mitigation

Users should avoid using version 0.1.0 of d8s-archives. The project maintainers recommend removing this version from PyPI [2]. As of the publication date (2022-10-11), no patched version has been explicitly mentioned; however, later versions (e.g., 0.7.0) are available and do not include the backdoor dependency [1]. Users should upgrade to the latest version and verify their dependencies.
