Last modified

CVE-2024-39780 is a critical-severity vulnerability rated 9.8/10 on the CVSS scale. A YAML deserialization vulnerability was found in the Robot Operating System (ROS) 'dynparam', a command-line tool for getting, setting, and deleting parameters of a dynamically configurable node, affecting ROS distributions Noetic and earlier. The issue is caused by the use of the yaml.load() function in the 'set' and 'get' verbs, and allows for the creation of arbitrary Python objects. EPSS estimates a 0.35% chance of exploitation in the next 30 days.

Description
