Automation Demands Tighter VM Security

Plan to let hypervisors spin up new virtual machines on their own? Then you'd better lock them down.

From a security standpoint, basic server hypervisors have a lot of intrinsic strength. They work at a very low level within a given piece of hardware. They're hardened and task-specific, and the code base is relatively small. And it's a good thing, because the hypervisor enjoys a privileged degree of access to guest operating systems, especially via OS-native virtual machine tools, which allow the hypervisor all sorts of power. Compromising the hypervisor gives complete and total access to all of the data structures that comprise the system itself. But when we asked about hypervisor security, only 64% of respondents to our survey cited concern about this issue. That leaves a staggering 36%--greater than one-third of respondents--who have their heads in the sand. If a system runs code, it can be compromised, and if that code is running everywhere, there's a huge incentive to break it. There have been no fewer than 10 major hypervisor vulnerabilities disclosed this year alone, affecting a variety of platforms. Exploits range from remote code execution vulnerabilities (the most severe) to denial of service, and while VMware has yet to disclose a remote code execution vulnerability, it's only a matter of time. Earlier this year, for example, outdated source code for VMware's ESX hypervisor was posted.

We still see companies with a long way to go to integrate hypervisor awareness into their overall security mandates. The good news is that vendors have been preparing for this eventuality for some time, as we discuss in our full report. Also, about half of survey respondents (48%) have a hypervisor-aware security product in place. An additional 32% plan to adopt one.

Enterprise Vulnerabilities
From DHS/US-CERT's National Vulnerability Database
CVE-2015-1009
Published: 2015-07-31
Schneider Electric InduSoft Web Studio before 7.1.3.5 Patch 5 and Wonderware InTouch Machine Edition through 7.1 SP3 Patch 4 use cleartext for project-window password storage, which allows local users to obtain sensitive information by reading a file.

CVE-2015-1486
Published: 2015-07-31
The management console in Symantec Endpoint Protection Manager (SEPM) 12.1 before 12.1-RU6-MP1 allows remote attackers to bypass authentication via a crafted password-reset action that triggers a new administrative session.

CVE-2015-1487
Published: 2015-07-31
The management console in Symantec Endpoint Protection Manager (SEPM) 12.1 before 12.1-RU6-MP1 allows remote authenticated users to write to arbitrary files, and consequently obtain administrator privileges, via a crafted filename.

CVE-2015-1488
Published: 2015-07-31
An unspecified action handler in the management console in Symantec Endpoint Protection Manager (SEPM) 12.1 before 12.1-RU6-MP1 allows remote authenticated users to read arbitrary files via unknown vectors.

CVE-2015-1489
Published: 2015-07-31
The management console in Symantec Endpoint Protection Manager (SEPM) 12.1 before 12.1-RU6-MP1 allows remote authenticated users to gain privileges via unspecified vectors.
