Description

Description

Redhat KeyCloak is prone to an authentication-bypass vulnerability. Remote attackers can exploit this issue to bypass the authentication mechanism and gain unauthorized access.

Technologies Affected

  • Redhat keycloak 7.0.0
  • Redhat keycloak 7.0.1.Final

Recommendations

Block external access at the network boundary, unless external parties require service.
If global access isn't needed, filter access to the affected computer at the network boundary. Restricting access to only trusted computers and networks might greatly reduce the likelihood of exploitation.

Run all software as a nonprivileged user with minimal access rights.
To reduce the impact of a successful attack, run the browser with the minimal amount of privileges required for functionality.

Deploy network intrusion detection systems to monitor network traffic for malicious activity.
Deploy NIDS to detect and block attacks and anomalous activity such as requests containing suspicious URI sequences. Since the webserver may log such requests, review its logs regularly.

Updates are available. Please see the references or vendor advisory for more information.
