Darknet: Security researches from the Polish firm Security Explorations have released a massive slew of PoC code and technical details on 30 Oracle Java Cloud Service Vulnerabilities. It seems like they had already reported them to Oracle, but weren’t happy with how things were handled, so have decided to go public with the weaknesses.
They gave them a fair amount of time too, over 2 months to address the issues in the cloud data centers. As a fairly new service though, it seems Oracle is having some issues with policies and handling incidents like this for their cloud service.
