CVE-2024-43191Network attack vector

Authenticated command execution via crafted YAML deserialization

Published Sep 26, 2024 · Updated Sep 26, 2024

Deserialization of untrusted YAML in IBM Cloud Pak for Multicloud Management 2.3 through 2.3 FP8 allows remote authenticated users to execute commands. IBM identifies the vulnerable locus only as ManageIQ's handling of crafted YAML file requests and has not published the affected function or deserialization path. Administrative access to the network-reachable interface is required, and successful exploitation grants command execution in the service context.
