The ESXi Host Client in VMware ESXi (6.5 before ESXi650-201712103-SG, 5.5 before ESXi600-201711103-SG and 5.5 before ESXi550-201709102-SG) contains a vulnerability that may allow for stored cross-site scripting (XSS). An attacker can exploit this vulnerability by injecting Javascript, which might get executed when other users access the Host Client.

In the add_match function in libbb/lineedit.c in BusyBox through 1.27.2, the tab autocomplete feature of the shell, used to get a list of filenames in a directory, does not sanitize filenames and results in executing any escape sequence in the terminal. This could potentially result in code execution, arbitrary file writes, or other attacks.

VMware ESXi 6.5 without patch ESXi650-201707101-SG, ESXi 6.0 without patch ESXi600-201706101-SG, ESXi 5.5 without patch ESXi550-201709101-SG, Workstation (12.x before 12.5.3), Fusion (8.x before 8.5.4) contain a NULL pointer dereference vulnerability. This issue occurs when handling guest RPC requests. Successful exploitation of this issue may allow attackers with normal user privileges to crash their VMs.

VMware ESXi (ESXi 6.5 without patch ESXi650-201707101-SG), Workstation (12.x before 12.5.7) and Fusion (8.x before 8.5.8) contain an out-of-bounds write vulnerability in SVGA device. This issue may allow a guest to execute code on the host.

This issue may allow a guest to execute code on the host.

Cross-site scripting (XSS) vulnerability in the Host Client in VMware vSphere Hypervisor (aka ESXi) 5.5 and 6.0 allows remote authenticated users to inject arbitrary web script or HTML via a crafted VM.

Untrusted search path vulnerability in the HGFS (aka Shared Folders) feature in VMware Tools 10.0.5 in VMware ESXi 5.0 through 6.0, VMware Workstation Pro 12.1.x before 12.1.1, VMware Workstation Player 12.1.x before 12.1.1, and VMware Fusion 8.1.x before 8.1.1 allows local users to gain privileges via a Trojan horse DLL in the current working directory.
