CVE-2014-3656

Name of the Vulnerable Software and Affected Versions JBoss KeyCloak (affected versions not specified)

Description The issue concerns a cross-site scripting (XSS) vulnerability. If a JBoss Keycloak application was configured to use * as a permitted web origin in the Keycloak administrative console, crafted requests to the "login-status-iframe.html" endpoint could inject arbitrary Javascript into the generated HTML code via the origin query parameter. This leads to a cross-site scripting (XSS) vulnerability, allowing for the execution of arbitrary JavaScript code.

Recommendations As a temporary workaround, consider restricting access to the "login-status-iframe.html" endpoint until a patch is available. Avoid using the * wildcard as a permitted web origin in the Keycloak administrative console to minimize the risk of exploitation. Restrict the use of the origin query parameter in the affected endpoint to prevent arbitrary JavaScript injection. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
