Descriptions

IBM WebSphere Application Server Network Deployment 7.0, 8.0, 8.5, and 9.0 could allow a remote attacker to execute arbitrary code on the system with a specially-crafted sequence of serialized objects from untrusted sources. IBM X-Force ID: 181228.

IBM WebSphere Application Server Network Deployment versiones 7.0, 8.0, 8.5 y 9.0, podría permitir a un atacante remoto ejecutar código arbitrario en el sistema con una secuencia de objetos serializados especialmente diseñada de fuentes no confiables. ID de IBM X-Force: 181228

This vulnerability allows remote attackers to execute arbitrary code on affected installations of IBM WebSphere. Authentication is not required to exploit this vulnerability.
The specific flaw exists within the BroadcastMessageManager class. The issue results from the lack of proper validation of user-supplied data, which can result in deserialization of untrusted data. An attacker can leverage this vulnerability to execute code in the context of SYSTEM.
