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.","cvssScore":9,"cvssSeverity":"CRITICAL","cvssVector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:C/C:H/I:H/A:H","cwes":["CWE-295"],"vendors":[],"products":[],"references":[{"url":"https://www.dell.com/support/kbdoc/en-in/000515444/dsa-2026-434-security-update-for-dell-terraform-provider-for-dell-server-multiple-vulnerabilities?msockid=3021cac2195069ed3194ddad186a68f9","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":{"summary":"Dell Terraform Provider for Redfish has a critical vulnerability where TLS certificate validation is completely disabled in its HTTP transport, allowing unauthenticated attackers to perform man-in-the-middle attacks and intercept all Redfish BMC traffic including sensitive credentials.","exploitability":"Very easy to exploit with no preconditions required since the vulnerability affects unauthenticated remote access and the TLS verification is unconditionally disabled.","blast_radius":"The vulnerability could impact all Dell servers using Redfish BMC management, potentially exposing hundreds or thousands of systems to credential theft and unauthorized access during network communication.","remediation":"Upgrade to version 1.6.2 or later","detection":"No reliable host or network indicator is derivable from the published description.","tags":["mitm","certificate-validation","redfish","bmc"],"model":"garnet-coder","analyzedAt":"2026-10-16T08:51:58.408Z"}}
