CVE-2024-32880Public exploitNetwork attack vector

Remote code execution via uploaded template rendering

Published Apr 26, 2024 · Updated Aug 2, 2024

Server-side template injection in pyLoad 4.2.0 and earlier allows remote authenticated users to execute arbitrary code via its web UI. The /json/add_package route saves an uploaded file beneath the configurable storage_folder, allowing placement in the template directory and rendering by render_template. An account with settings and package-upload privileges can execute commands with the pyLoad service's permissions by requesting the uploaded template.
