Proof-of-concept exploit code is now publicly available online for a critical authentication bypass security flaw in multiple VMware products that enables attackers to gain admin privileges.
A week ago, VMware released updates to address the vulnerability affecting VMware Workspace ONE Access, Identity Manager, and vRealize Automation.
Today, VMware “Confirmed malicious code that can exploit CVE-2022-31656 and CVE-2022-31659 in impacted products is publicly available” in an update to the original advisory.
Luckily, VMware says in a separate advisory that there is no evidence that these severe security bugs are being exploited in attacks.
As VMware servers are an attractive target, all vulnerable devices should be updated immediately or taken offline to avoid compromise since threat actors will likely soon develop their own exploits to use in attacks.
In May, VMware patched an almost identical critical bug, another authentication bypass weakness found by Bruno López of Innotec Security and used by Viet as inspiration while researching the CVE-2022-31656 vulnerability.
