Technical details
The vulnerability is an XXE injection in the SAML IdP metadata parsing logic within Omada Controller's SSO functionality. An authenticated user with SAML configuration privileges can supply malicious SAML metadata containing external entity declarations to extract local files. The attack requires network access to the controller and valid administrative credentials with SAML configuration rights. Successful exploitation results in unauthorized disclosure of sensitive information stored on the controller.
