CVE-2024-39780

Summary

CVE-2024-39780 is a new vulnerability affecting the Robot Operating System (ROS) 'dynparam' tool in ROS distributions Noetic and earlier. This command-line utility, used for getting, setting, and deleting parameters of a dynamically configurable node, contains a YAML deserialization flaw. The issue arises due to the implementation of yaml.load() function in the 'set' and 'get' verbs, which can result in the creation of arbitrary Python objects. Consequently, a local or remote user can exploit this vulnerability to execute arbitrary Python code. The latest version of ROS Noetic, with commit 3d93ac13603438323d7e9fa74e879e45c5fe2e8e, addresses this security weakness.
