Accessing, Modifying or Executing Executable Files
An attack of this type exploits a system's configuration that allows an attacker to either directly access an executable file, for example through shell access; or in a possible worst case allows an attacker to upload a file and then execute it. Web servers, ftp servers, and message oriented middleware systems which have many integration points are particularly vulnerable, because both the programmers and the administrators must be in synch regarding the interfaces and the correct privileges for each interface.
Leverage Executable Code in Non-Executable Files
An attack of this type exploits a system's trust in configuration and resource files, when the executable loads the resource (such as an image file or configuration file) the attacker has modified the file to either execute malicious code directly or manipulate the target process (e.g. application server) to execute based on the malicious configuration parameters. Since systems are increasingly interrelated mashing up resources from local and remote sources the possibility of this attack occurring is high.
The attack can also target server processes. The attacker edits the resource or configuration file, for example a web.xml file used to configure security permissions for a J2EE app server, adding role name "public" grants all users with the public role the ability to use the administration functionality.
The server trusts its configuration file to be correct, but when they are manipulated, the attacker gains full control.
This type of attack against older telephone switches and trunks has been around for decades. A tone is sent by an adversary to impersonate a supervisor signal which has the effect of rerouting or usurping command of the line. While the US infrastructure proper may not contain widespread vulnerabilities to this type of attack, many companies are connected globally through call centers and business process outsourcing. These international systems may be operated in countries which have not upgraded Telco infrastructure and so are vulnerable to Blue boxing. Blue boxing is a result of failure on the part of the system to enforce strong authorization for administrative functions. While the infrastructure is different than standard current applications like web applications, there are historical lessons to be learned to upgrade the access control for administrative functions.
Restful Privilege Elevation
Rest uses standard HTTP (Get, Put, Delete) style permissions methods, but these are not necessarily correlated generally with back end programs. Strict interpretation of HTTP get methods means that these HTTP Get services should not be used to delete information on the server, but there is no access control mechanism to back up this logic. This means that unless the services are properly ACL'd and the application's service implementation are following these guidelines then an HTTP request can easily execute a delete or update on the server side.
The attacker identifies a HTTP Get URL such as http://victimsite/updateOrder, which calls out to a program to update orders on a database or other resource. The URL is not idempotent so the request can be submitted multiple times by the attacker, additionally, the attacker may be able to exploit the URL published as a Get method that actually performs updates (instead of merely retrieving data). This may result in malicious or inadvertent altering of data on the server.
Target Programs with Elevated Privileges
This attack targets programs running with elevated privileges. The attacker would try to leverage a bug in the running program and get arbitrary code to execute with elevated privileges. For instance an attacker would look for programs that write to the system directories or registry keys (such as HKLM, which stores a number of critical Windows environment variables). These programs are typically running with elevated privileges and have usually not been designed with security in mind. Such programs are excellent exploit targets because they yield lots of power when they break. The malicious user try to execute its code at the same level as a privileged system call.
Manipulating Input to File System Calls
An attacker manipulates inputs to the target software which the target software passes to file system calls in the OS. The goal is to gain access to, and perhaps modify, areas of the file system that the target software did not intend to be accessible.

|description||The remote host is affected by the vulnerability described in GLSA-201209-25 (VMware Player, Server, Workstation: Multiple vulnerabilities)
Multiple vulnerabilities have been discovered in VMware Player, Server, and Workstation. Please review the CVE identifiers referenced below for details.
Local users may be able to gain escalated privileges, cause a Denial of Service, or gain sensitive information.
A remote attacker could entice a user to open a specially crafted file, possibly resulting in the remote execution of arbitrary code, or a Denial of Service. Remote attackers also may be able to spoof DNS traffic, read arbitrary files, or inject arbitrary web script to the VMware Server Console.
Furthermore, guest OS users may be able to execute arbitrary code on the host OS, gain escalated privileges on the guest OS, or cause a Denial of Service (crash the host OS).
There is no known workaround at this time. |

b. Windows-based VMware Tools Arbitrary Code Execution vulnerability
A vulnerability in the way VMware executables are loaded allows for arbitrary code execution in the context of the logged on user. This vulnerability is present only on Windows Guest Operating Systems.
In order for an attacker to exploit the vulnerability, the attacker would need to be able to plant their malicious executable in a certain location on the Virtual Machine of the user. On most recent versions of Windows (XP, Vista) the attacker would need to have administrator privileges to plant the malicious executable in the right location.
Steps needed to remediate this vulnerability: See section 3.a.
VMware would like to thank Mitja Kolsek of ACROS Security (http://www.acrossecurity.com) for reporting this issue to us.
The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2010-1142 to this issue.
Refer to the previous table in section 3.a for what action remediates the vulnerability (column 4) if a solution is available. See above for remediation details.
c. Windows-based VMware Workstation and Player host privilege escalation
A vulnerability in the USB service allows for a privilege escalation. A local attacker on the host of a Windows-based Operating System where VMware Workstation or VMware Player is installed could plant a malicious executable on the host and elevate their privileges.
In order for an attacker to exploit the vulnerability, the attacker would need to be able to plant their malicious executable in a certain location on the host machine. On most recent versions of Windows (XP, Vista) the attacker would need to have administrator privileges to plant the malicious executable in the right location.
VMware would like to thank Thierry Zoller for reporting this issue to us.
The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2010-1140 to this issue.
d. Third-party library update for libpng to version 1.2.37
The libpng libraries through 1.2.35 contain an uninitialized- memory-read bug that may have security implications.
Specifically, 1-bit (2-color) interlaced images whose widths are not divisible by 8 may result in several uninitialized bits at the end of certain rows in certain interlace passes being returned to the user. An application that failed to mask these out-of-bounds pixels might display or process them, albeit presumably with benign results in most cases.
The Common Vulnerabilities and Exposures Project (cve.mitre.org) has assigned the name CVE-2009-2042 to this issue.
e. VMware VMnc Codec heap overflow vulnerabilities
The VMware movie decoder contains the VMnc media codec that is required to play back movies recorded with VMware Workstation, VMware Player and VMware ACE, in any compatible media player. The movie decoder is installed as part of VMware Workstation, VMware Player and VMware ACE, or can be downloaded as a stand alone package.
Vulnerabilities in the decoder allow for execution of arbitrary code with the privileges of the user running an application utilizing the vulnerable codec.
For an attack to be successful the user must be tricked into visiting a malicious web page or opening a malicious video file on a system that has the vulnerable version of the VMnc codec installed.
The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the names CVE-2009-1564 and CVE-2009-1565 to these issues.
VMware would like to thank iDefense, Sebastien Renaud of VUPEN Vulnerability Research Team (http://www.vupen.com) and Alin Rad Pop of Secunia Research for reporting these issues to us.
To remediate the above issues either install the stand alone movie decoder or update your product using the table below.
f. VMware Remote Console format string vulnerability
VMware Remote Console (VMrc) contains a format string vulnerability.
Exploitation of this issue may lead to arbitrary code execution on the system where VMrc is installed.
For an attack to be successful, an attacker would need to trick the VMrc user into opening a malicious Web page or following a malicious URL. Code execution would be at the privilege level of the user.
VMrc is present on a system if the VMrc browser plug-in has been installed. This plug-in is required when using the console feature in WebAccess. Installation of the plug-in follows after visiting the console tab in WebAccess and choosing 'Install plug-in'. The plug- in can only be installed on Internet Explorer and Firefox.
Under the following two conditions your version of VMrc is likely to be affected :
- the VMrc plug-in was obtained from vCenter 4.0 or from ESX 4.0 without patch ESX400-200911223-UG and
- VMrc is installed on a Windows-based system
The following steps allow you to determine if you have an affected version of VMrc installed :
- Locate the VMrc executable vmware-vmrc.exe on your Windows-based system
- Right click and go to Properties
- Go to the tab 'Versions'
- Click 'File Version' in the 'Item Name' window
- If the 'Value' window shows 'e.x.p build-158248', the version of VMrc is affected
Remediation of this issue on Windows-based systems requires the following steps (Linux-based systems are not affected) :
- Uninstall affected versions of VMrc from the systems where the VMrc plug-in has been installed (use the Windows Add/Remove Programs interface)
- Install vCenter 4.0 Update 1 or install the ESX 4.0 patch ESX400-200911223-UG
- Login into vCenter 4.0 Update 1 or ESX 4.0 with patch ESX400-200911223-UG using WebAccess on the system where the VMrc needs to be re-installed
- Re-install VMrc by going to the console tab in WebAccess. The Console tab is selectable after selecting a virtual machine.
Note: the VMrc plug-in for Firefox on Windows-based operating systems is no longer compatible after the above remediation steps.
Users are advised to use the Internet Explorer VMrc plug-in.
VMware would like to thank Alexey Sintsov from Digital Security Research Group for reporting this issue to us.
The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2009-3732 to this issue.
g. Windows-based VMware authd remote denial of service
A vulnerability in vmware-authd could cause a denial of service condition on Windows-based hosts. The denial of service is limited to a crash of authd.
The Common Vulnerabilities and Exposures Project (cve.mitre.org) has assigned the name CVE-2009-3707 to this issue.
h. Potential information leak via hosted networking stack
A vulnerability in the virtual networking stack of VMware hosted products could allow host information disclosure.
A guest operating system could send memory from the host vmware-vmx process to the virtual network adapter and potentially to the host's physical Ethernet wire.
The Common Vulnerabilities and Exposures Project (cve.mitre.org) has assigned the name CVE-2010-1138 to this issue.
VMware would like to thank Johann MacDonagh for reporting this issue to us.
i. Linux-based vmrun format string vulnerability
