Official description
Xecurify's miniOrange Premium, Standard, and Enterprise Drupal SAML SP modules possess an authentication and authorization bypass vulnerability. An attacker with access to a HTTP-request intercepting method is able to bypass authentication and authorization by removing the SAML Assertion Signature - impersonating existing users and existing roles, including administrative users/roles. This vulnerability is not mitigated by configuring the module to enforce signatures or certificate checks. Xecurify recommends updating miniOrange modules to their most recent versions. This vulnerability is present in paid versions of the miniOrange Drupal SAML SP product affecting Drupal 7, 8, and 9.

The underlying weakness: Improper Certificate Validation
The product does not validate, or incorrectly validates, a certificate.
How developers prevent this class of flaw
- Certificates should be carefully managed and checked to assure that data are encrypted with the intended owner's public key.
- If certificate pinning is being used, ensure that all relevant properties of the certificate are fully validated before the certificate is pinned, including the hostname.
