medium Nessus Plugin ID 87940

Language:

Synopsis

The remote VMware ESXi 5.0 host is affected by a guest privilege escalation vulnerability.

Description

The remote VMware ESXi 5.0 host is prior to build 3086167. It is, therefore, affected by a guest privilege escalation vulnerability in the Shared Folders (HGFS) feature due to improper validation of user-supplied input. A local attacker can exploit this to corrupt memory, resulting in an elevation of privileges.

Solution

Apply patch ESXi500-201510102-SG according to the vendor advisory.

Note that VMware Tools in any Windows-based guests that use the Shared Folders (HGFS) feature must also be updated to completely mitigate the vulnerability.
