Summary

Dell Terraform Provider for Redfish versions prior to 1.6.2 contains an improper certificate validation flaw (CWE-295) in its HTTP transport component. TLS certificate verification is unconditionally disabled, so a remote unauthenticated attacker in a man-in-the-middle position can intercept all Redfish BMC traffic, including credentials. Successful exploitation can lead to information exposure and unauthorized access.
