CVE-2026-91881

Quick assessment

Affected
Dell Terraform Provider for Redfish
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

Dell Redfish Terraform Provider 1.6.2 之前的版本在 HTTP 传输组件中存在证书验证不当漏洞。未认证的攻击者若具备远程访问权限，则可能利用该漏洞，导致信息泄露和未授权访问。该漏洞被评定为严重级别，因为通过中间人攻击，未认证的攻击者能够截获所有 Redfish BMC 流量，包括凭据，这是因为基础 HTTP 传输层无条件禁用了 TLS 证书验证。Dell 建议客户尽早升级至最新版本。

Vulnerability Description
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.
