CVSS 9.0 (CRITICAL)
Affected Versions before 1.6.2
Type CWE-295 (Improper Certificate Validation)
Vendor Dell
Public PoC No

Dell Terraform Provider for Redfish, versions prior to 1.6.2, contains an Improper Certificate Validation vulnerability in the HTTP transport component. An unauthenticated attacker with remote access could potentially exploit this vulnerability, leading to information exposure and unauthorized access. This is a Critical severity vulnerability as it allows an unauthenticated attacker to intercept all Redfish BMC traffic including credentials by performing a man-in-the-middle attack, since TLS certificate verification is unconditionally disabled in the base HTTP transport.

Dell recommends customers to upgrade at the earliest opportunity.
