Impact
A flaw was found in Wildfly Elytron integration. The component does not implement sufficient measures to prevent multiple failed authentication attempts within a short time frame, making it more susceptible to brute force attacks via CLI.
Patches
The default behaviour has been changed in WildFly Core 31.0.3.Final, and 32.0.0.Beta3 - the first version is used by WildFly 39.0.1.Final and the second will be included in WildFly 40.
Workarounds
No direct workaround. Monitoring network traffic / blocking suspicious traffic may help.
