Summary

IBM WebSphere Application Server may be vulnerable to a denial of service, caused by allowing serialized objects from untrusted sources to run and cause the consumption of resources.

Common Weakness Enumeration (CWE)

Nessus

NASL familyWeb Servers
NASL idWEBSPHERE_SWG21993797.NASL
descriptionThe IBM WebSphere Application Server running on the remote host is version 7.0.0.x prior to 7.0.0.43, 8.0.0.x prior to 8.0.0.14, 8.5.x prior to 8.5.5.12, or 9.0.0.x prior to 9.0.0.4. It is, therefore, affected by an input validation flaw in SOAP connectors that allows a remote user to cause serialized objects to run, consuming excessive resources on the target system.
