Descriptions
A flaw was found in Keycloak that prevents certain schemes in redirects, but permits them if a wildcard is appended to the token. This issue could allow an attacker to submit a specially crafted request leading to cross-site scripting (XSS) or further attacks. This flaw is the result of an incomplete fix for CVE-2020-10748.
Se encontró una falla en Keycloak que impide ciertos esquemas en las redirecciones, pero los permite si se agrega un comodín al token. Este problema podría permitir que un atacante envíe una solicitud especialmente manipulada que dé lugar a cross-site scripting (XSS) o más ataques. Esta falla es el resultado de una solución incompleta para CVE-2020-10748.
A new image is available for Red Hat Single Sign-On 7.6.6, running on OpenShift Container Platform 3.10 and 3.11, and 4.3. Issues addressed include bypass, cross site scripting, and denial of service vulnerabilities.
