VMware Announces Fixes for Numerous Security Vulnerabilities: Immediate Update Recommended

In a recent stride toward fortifying its digital fortress, VMware has implemented a series of important security updates across its flagship products. With the emergence of vulnerabilities that könnte potentially open the door to remote code execution, VMware is urging its users to act swiftly and apply the recommended patches without delay.

The spotlight falls on four identified vulnerabilities: CVE-2024-22252, CVE-2024-22253, CVE-2024-22254, and CVE-2024-22255. These vulnerabilities make their presence known within the ESXi, Workstation, and Fusion products, underscoring a critical need for immediate attention.

The opening act in this quartet features CVE-2024-22252 and CVE-2024-22253, which share the stage as use-after-free vulnerabilities within the XHCI USB controller. This troublesome duo impacts all three aforementioned VMware products. Specifically, for users of Workstation and Fusion, these vulnerabilities hold a severity score of 9.3, suggesting a high impact. Meanwhile, ESXi users face a slightly lesser although still concerning severity score of 8.4.

But what does this actually mean for you? Imagine, if you will, a malicious entity gaining administrative control over a virtual machine. Utilizing these vulnerabilities, such an actor could orchestrate code execution with the finesse of a puppeteer – manipulating the VM’s very core processes. For those navigating the realms of ESXi, this manipulation is somewhat contained within the VMX sandbox. However, Workstation and Fusion users find themselves in a more precarious position, facing the possibility of their machine being hijacked.

The narrative further thickens with two additional vulnerabilities – an out-of-bounds write flaw in ESXi, and an information disclosure flaw in the UHCI USB controller, both rated with a severity score of 7.9. These particular flaws hold the potential for sandbox escape and the unauthorized siphoning of memory from the VMX processes.

To shield your digital environment from these lurking threats, VMware has laid out a roadmap to safety, recommending updates to specific product versions. For ESXi, the safe harbors are versions 6.5U3v, 6.7U3u, ESXi70U3p-23307199, ESXi80U2sb-23305545, and ESXi80U1d-23299997. Meanwhile, VMware Cloud Foundation users should navigate to version 3.x, and those utilizing Workstation 17.x and Fusion 13.x (macOS) are advised to upgrade to versions 17.5.1 and 13.5.1, respectively.

For those unable to immediately embark on this update journey, a stopgap solution is to detach all USB controllers from your virtual vessels. While this measure takes USB-based tools out of your virtual machine’s arsenal, rest easy knowing it doesn’t affect your trusty keyboard and mouse, as these essential peripherals are not marooned by this workaround.
