Markdown-supplied Shell Command Execution
Résumé
Markdown-supplied Shell Command Execution
Description d'origine
La description telle que publiée par la source (souvent en anglais).
Impact
lookatme versions prior to 2.3.0 automatically loaded the built-in "terminal" and "file_loader" extensions. Users that use lookatme to render untrusted markdown may have malicious shell commands automatically run on their system.
Patches
Users should upgrade to lookatme versions 2.3.0 or above.
Workarounds
The lookatme/contrib/terminal.py and lookatme/contrib/file_loader.py files may be manually deleted. Additionally, it is always recommended to be aware of what is being rendered with lookatme.
