Descriptions

The Standalone Enqueue Server in SAP Netweaver 7.20, 7.01, and earlier allows remote attackers to cause a denial of service (uncontrolled recursion and crash) via a trace level with a wildcard in the Trace Pattern.

El servidor Standalone Enqueue en SAP Netweaver 7.20, 7.01, y anteriores permite a atacantes remotos causar una denegación de servicio (recursión sin control y caída) a través de un nivel de traza con un comodín en la pauta de traza (Trace Pattern).

Core Security Technologies Advisory - A vulnerability has been found in SAP Netweaver that could allow an unauthenticated, remote attacker to create denial of service conditions. The vulnerability is triggered by sending a specially crafted SAP Enqueue Server packet to remote TCP port 32NN (NN being the SAP system number) of a host running the "Standalone Enqueue Server" service, part of SAP Netweaver Application Server ABAP/Java. The "Standalone Enqueue Server" is a critical component of a SAP Netweaver installation in terms of availability, rendering the whole SAP system unresponsive.
