Over 45,000 VMware ESXi servers inventoried by Lansweeper simply reached end-of-life (EOL), with VMware now not offering software program and safety updates until firms buy an prolonged help contract.
Lansweeper develops asset administration and discovery software program that enables clients to trace what {hardware} and software program they’re working on their community.
As of October 15, 2022, VMware ESXi 6.5 and VMware ESXi 6.7 reached end-of-life and can solely obtain technical help however no safety updates, placing the software program prone to vulnerabilities.
The corporate analyzed knowledge from 6,000 clients and located 79,000 put in VMware ESXi servers.
Of these servers, 36.5% (28,835) run model 6.7.0, launched in April 2018, and 21.3% (16,830) are on model 6.5.0, launched in November 2016. In whole, there are 45,654 VMware ESXi servers reaching Finish of Life as of at this time
The findings of Lansweeper are alarming as a result of other than the 57% that enter a interval of elevated threat, there are additionally one other 15.8% installations that run even older variations, starting from 3.5.0 to five.5.0, which reached EOL fairly a while in the past.
In abstract, proper now, solely about one out of 4 ESXi servers (26.4%) inventoried by Lansweeper are nonetheless supported and can proceed to obtain common safety updates till April 02, 2025.
Nevertheless, in actuality, the variety of VMware servers reaching EOL at this time, is probably going far larger, as this report relies solely on Lansweeper’s clients.

The technical steering for ESXi 6.5 and 6.7 will keep on till November 15, 2023, however this issues implementation points, not together with safety threat mitigation.
The one manner to make sure you can proceed to make use of older variations securely is to use for the two-year prolonged help, which must be bought individually. Nevertheless, this doesn’t embrace updates for third-party software program packages.
For extra particulars about EOL dates on all VMware software program merchandise, take a look at this webpage.
What does this imply?
When a software program product reaches the end-of-life date, it stops receiving common safety updates. Because of this admins ought to have already deliberate forward and upgraded all deployments to a more moderen launch.
Whereas it’s not unlikely that VMware will nonetheless provide some essential safety patches for these older variations, it’s not assured and positively received’t launch patches for all new vulnerabilities which are found.
As soon as an unsupported ESXi server has carried on for lengthy sufficient with out patches, it’ll have amassed so many safety vulnerabilities that attackers would have a number of methods to breach it.
Attributable to ESXi internet hosting digital machines, attacking the server can probably trigger extreme and wide-scale disruption to enterprise operations, which is why ransomware gangs are so centered on concentrating on it.
This yr, ESXi VMs have been focused by the likes of Black Basta, RedAlert, GwisinLocker, Hive, and the Cheers ransomware gangs.
Extra just lately, Mandiant found that hackers discovered a brand new methodology to ascertain persistence on VMware ESXi hypervisors that lets them management the server and hosted VMs with out being detected.
All that stated, ESXi already enjoys ample consideration from menace actors, so working outdated and weak variations of the software program would little doubt be a horrible thought.
