Single Sign-On for Vmware Tanzu all versions prior to 1.11.3 ,1.12.x versions prior to 1.12.4 and 1.13.x prior to 1.13.1 are vulnerable to user impersonation attack.If two users are logged in to the SSO operator dashboard at the same time, with the same username, from two different identity providers, one can acquire the token of the other and thus operate with their permissions. Note: Foundation may be vulnerable only if: 1) The system zone is set up to use a SAML identity provider 2) There are internal users that have the same username as users in the external SAML provider 3) Those duplicate-named users have the scope to access the SSO operator dashboard 4) The vulnerability doesn’t appear with LDAP because of chained authentication.
