SAP NetWeaver 7400.12.21.30308 allows remote attackers to cause a denial of service and possibly execute arbitrary code via a crafted serialized Java object in a request to metadatauploader, aka SAP Security Note 2399804. NOTE: The vendor states that the devserver package of Visual Composer deserializes a malicious object that may cause legitimate users accessing a service, either by crashing or flooding the service.
