Categoría:	VMware Local Security Checks
Título:	VMware ESXi/ESX unauthorized file access through vCenter Server and ESX (VMSA-2013-0016) - Local Version Check
Resumen:	VMware ESXi and ESX unauthorized file access through vCenter; Server and ESX.
Descripción:	Summary: VMware ESXi and ESX unauthorized file access through vCenter Server and ESX. Vulnerability Insight: VMware ESXi and ESX contain a vulnerability in the handling of certain Virtual Machine file descriptors. This issue may allow an unprivileged vCenter Server user with the privilege 'Add Existing Disk' to obtain read and write access to arbitrary files on ESXi or ESX. On ESX, an unprivileged local user may obtain read and write access to arbitrary files. Modifying certain files may allow for code execution after a host reboot. Unprivileged vCenter Server users or groups that are assigned the predefined role 'Virtual Machine Power User' or 'Resource Pool Administrator' have the privilege 'Add Existing Disk'. The issue cannot be exploited through VMware vCloud Director. Affected Software/OS: VMware ESXi 5.5 without patch ESXi550-201312001 VMware ESXi 5.1 without patch ESXi510-201310001 VMware ESXi 5.0 without patch update-from-esxi5.0-5.0_update03 VMware ESXi 4.1 without patch ESXi410-201312001 VMware ESXi 4.0 without patch ESXi400-201310001 VMware ESX 4.1 without patch ESX410-201312001 VMware ESX 4.0 without patch ESX400-201310001 Solution: Apply the missing patch(es). Workaround A workaround is provided in VMware Knowledge Base article 2066856. Mitigation In a default vCenter Server installation no unprivileged users or groups are assigned the predefined role 'Virtual Machine Power User' or 'Resource Pool Administrator'. Restrict the number of vCenter Server users that have the privilege 'Add Existing Disk'. CVSS Score: 4.4 CVSS Vector: AV:L/AC:M/Au:N/C:P/I:P/A:P
