Oracle VM VirtualBox 5.0.x < 5.0.34 / 5.1.x < 5.1.16 Shared Folder Implementation Information Disclosure

high Nessus Plugin ID 99200

Language:

Synopsis

An application installed on the remote host is affected by an information disclosure vulnerability.

Description

The version of Oracle VM VirtualBox installed on the remote host is 5.0.x prior to 5.0.34 or 5.1.x prior to 5.1.16. It is, therefore, affected by an information disclosure vulnerability within the shared folder implementation, specifically in the vbsfPathCheckRootEscape() function, that permits cooperating guests that have write access to the same shared folder to gain access to the file system of the Linux host. An authenticated attacker within a guest VM can exploit this to read arbitrary files on the host. However, exploitation requires that the shared folder is not more than nine levels away from the file system root.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Upgrade to Oracle VM VirtualBox version 5.0.34 / 5.1.16 or later
