  • The BIND DNS server has already been deprecated and removed from Plesk for Windows.
    If a Plesk for Windows server is still using BIND, the upgrade to Plesk Obsidian 18.0.70 will be unavailable until the administrator switches the DNS server to Microsoft DNS. We strongly recommend transitioning to Microsoft DNS within the next 6 weeks, before the Plesk 18.0.70 release.
  • The Horde component is removed from Plesk Installer. We recommend switching to another webmail software supported in Plesk.

Hi everyone, as the title suggests, I have this great doubt .. but if a WordPress or prestashop site is hacked, etc., is the attack limited to the specific plesk account or can I suffer damage to my entire system? a thousand thanks
 
That entirely depends on how it was hacked. If they just exploited a rotten plugin you might be in luck. If they got shell access and managed further privilege escalation ... you're not.
 
That would only help against the hacker getting a leaked password and using it to get shell access the normal way.
The question here is whether the security hole they used to get in was big enough to give them shell access by other means.
 
The way Plesk is designed on the users ( domain accounts ) just allows most of the time access only to that user files. If you dont change the original permissions on the folders its likely it wont access other domains ( and clients ) on a server.
A secure setup is to deny shell access.
I modify my ssh to only accept keys
