IBM WebSphere Java Object Deserialization RCE

critical Nessus Plugin ID 87171


The remote WebSphere Application Server is affected by a remote code execution vulnerability.


The remote IBM WebSphere Application Server is affected by a remote code execution vulnerability due to unsafe deserialize calls of unauthenticated Java objects to the Apache Commons Collections (ACC) library. An unauthenticated, remote attacker can exploit this, by sending a crafted SOAP request, to execute arbitrary code on the target host.


Apply the appropriate interim fix per the vendor advisory.
Alternatively, ensure that all exposed ports used by the WebSphere Application Server are firewalled from any public networks.
