CVE-2021-24105 – Package Managers Configurations Remote Code Execution Vulnerability

https://notcve.org/view.php?id=CVE-2021-24105

25 Feb 2021 —

Depending on configuration of various package managers it is possible for an attacker to insert a malicious package into a package manager's repository which can be retrieved and used during development, build, and release processes. This insertion could lead to remote code execution. We believe this vulnerability affects multiple package managers across multiple languages, including but not limited to: Python/pip, .NET/NuGet, Java/Maven, JavaScript/npm.
