Описание
Vault and Vault Enterprise’s (“Vault”) ldap auth method may not have correctly enforced MFA if username_as_alias was set to true and a user had multiple CNs that are equal but with leading or trailing spaces. Fixed in Vault Community Edition 1.20.2 and Vault Enterprise 1.20.2, 1.19.8, 1.18.13, and 1.16.24.
A flaw was found in github.com/hashicorp/vault. The LDAP authentication method fails to properly enforce multi-factor authentication when username_as_alias is enabled and a user possesses multiple Common Names (CNs) containing differing leading or trailing spaces. A remote attacker authenticated as a user meeting these conditions can bypass MFA. This can allow unauthorized access to resources protected by Vault. The underlying issue is an incorrect comparison of Common Names.
