What is CVE-2024-40641?
CVE-2024-40641 is a high-severity command injection vulnerability in projectdiscovery nuclei, published on 17 Jul 2024. It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.
Official description
Nuclei is a fast and customizable vulnerability scanner based on simple YAML based DSL. In affected versions it a way to execute code template without -code option and signature has been discovered. Some web applications inherit from Nuclei and allow users to edit and execute workflow files. In this case, users can execute arbitrary commands. (Although, as far as I know, most web applications use -t to execute). This issue has been addressed in version 3.3.0. Users are advised to upgrade. There are no known workarounds for this vulnerability.
