Name of the Vulnerable Software and Affected Versions Red Hat JBoss Enterprise Application Platform (EAP) version 7

Description The issue allows remote attackers to cause a denial of service, consuming CPU and disk resources, by sending a long URL when the platform operates as a reverse-proxy with default buffer sizes. This can lead to a java.nio.BufferOverflowException in Undertow.

Recommendations For Red Hat JBoss Enterprise Application Platform (EAP) version 7, consider adjusting the default buffer sizes to prevent excessive CPU and disk consumption when handling long URL proxy requests. As a temporary workaround, restrict the maximum allowed URL length to minimize the risk of exploitation.
