Detailsinfo

A vulnerability was found in HashiCorp Tooling up to 5.4.x and classified as problematic. This issue affects an unknown functionality of the component LDAP Auth Method Handler. The manipulation of the argument deny_null_bind with an unknown input leads to a insecure default initialization of resource vulnerability. Using CWE to declare the problem leads to CWE-1188. The product initializes or sets a resource with a default that is intended to be changed by the administrator, but the default is not secure. Impacted is confidentiality, integrity, and availability. The summary by CVE is:

Vault’s Terraform Provider incorrectly set the default deny_null_bind parameter for the LDAP auth method to false by default, potentially resulting in an insecure configuration. If the underlying LDAP server allowed anonymous or unauthenticated binds, this could result in authentication bypass. This vulnerability, CVE-2025-13357, is fixed in Vault Terraform Provider v5.5.0.
