This is a service alert for any customers using Vesta Control Panel. Over the last 48 hours there has been a suspected vulnerability in Vesta or one of Vesta's associated installed products which has seen numerous servers around the world hacked for DDOS/Botnet purposes. There has been an official word from Vesta with regards to an update released yesterday, however, it is not confirmed this has resolved the issue. As a result we have blocked port 8083 in our incoming hardware firewall for all customers until the root cause is officially identified.
Details at this stage are minimal, you can follow the thread at https://forum.vestacp.com
