a. VMware ESXi and ESX unauthorized file access through vCenter Server and ESX
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.
Unpriviledged 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.
VMware would like to thank Shanon Olsson for reporting this issue to us through JPCERT.
The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2013-5973 to this issue.
Column 4 of the following table lists the action required to remediate the vulnerability in each release, if a solution is available.
Known Issues (*)
Deploying these patches does not remediate the issue if the ESXi or ESX file /etc/vmware/configrules has been modified manually (modifying this file is uncommon). Customers who have modified this file should apply the workaround after installing the patch.
After deploying the patches, Virtual Machines that have their names ending in "-flat", "-rdm" or "-rdmp" will no longer power on. See the VMware Knowledge Base article listed under "Workaround" for a solution.
Please review the patch/release notes for your product and version and verify the checksum of your downloaded file.
