Описание
A flaw was found in Keycloak. A remote, unauthenticated attacker can exploit this vulnerability by sending specially crafted SOAP requests to the SAML ECP (Security Assertion Markup Language Enhanced Client or Proxy) endpoint with varying client IDs. By observing distinct faultstrings in the responses, the attacker can determine the client's protocol type, leading to information disclosure.
Отчет
This Moderate-severity information disclosure flaw in Keycloak allows an unauthenticated, remote attacker to enumerate client protocol types. By sending specially crafted SOAP requests to the SAML ECP endpoint and analyzing the resulting faultstrings, an attacker can discern the protocol associated with different client IDs, aiding in further targeted attacks.
