Subverting Environment Variable Values
The attacker directly or indirectly modifies environment variables used by or controlling the target software. The attacker's goal is to cause the target software to deviate from its expected operation in a manner that benefits the attacker.
An attacker engages in probing and exploration activity to identify constituents and properties of the target. Footprinting is a general term to describe a variety of information gathering techniques, often used by attackers in preparation for some attack. It consists of using tools to learn as much as possible about the composition, configuration, and security mechanisms of the targeted application, system or network. Information that might be collected during a footprinting effort could include open ports, applications and their versions, network topology, and similar information. While footprinting is not intended to be damaging (although certain activities, such as network scans, can sometimes cause disruptions to vulnerable applications inadvertently) it may often pave the way for more damaging attacks.
Exploiting Trust in Client (aka Make the Client Invisible)
An attack of this type exploits a programs' vulnerabilities in client/server communication channel authentication and data integrity. It leverages the implicit trust a server places in the client, or more importantly, that which the server believes is the client.
An attacker executes this type of attack by placing themselves in the communication channel between client and server such that communication directly to the server is possible where the server believes it is communicating only with a valid client.
There are numerous variations of this type of attack.
An attacker carefully crafts small snippets of Java Script to efficiently detect the type of browser the potential victim is using. Many web-based attacks need prior knowledge of the web browser including the version of browser to ensure successful exploitation of a vulnerability. Having this knowledge allows an attacker to target the victim with attacks that specifically exploit known or zero day weaknesses in the type and version of the browser used by the victim. Automating this process via Java Script as a part of the same delivery system used to exploit the browser is considered more efficient as the attacker can supply a browser fingerprinting method and integrate it with exploit code, all contained in Java Script and in response to the same web page request by the browser.
Session Credential Falsification through Prediction
This attack targets predictable session ID in order to gain privileges. The attacker can predict the session ID used during a transaction to perform spoofing and session hijacking.
Reusing Session IDs (aka Session Replay)
This attack targets the reuse of valid session ID to spoof the target system in order to gain privileges. The attacker tries to reuse a stolen session ID used previously during a transaction to perform spoofing and session hijacking. Another name for this type of attack is Session Replay.
Using Slashes in Alternate Encoding
This attack targets the encoding of the Slash characters. An attacker would try to exploit common filtering problems related to the use of the slashes characters to gain access to resources on the target host. Directory-driven systems, such as file systems and databases, typically use the slash character to indicate traversal between directories or other container components. For murky historical reasons, PCs (and, as a result, Microsoft OSs) choose to use a backslash, whereas the UNIX world typically makes use of the forward slash. The schizophrenic result is that many MS-based systems are required to understand both forms of the slash. This gives the attacker many opportunities to discover and abuse a number of common filtering problems. The goal of this pattern is to discover server software that only applies filters to one version, but not the other.

|description||a. Denial of service guest to host vulnerability in a virtual device
A vulnerability in a guest virtual device driver, could allow a guest operating system to crash the host and consequently any virtual machines on that host.
VMware would like to thank Andrew Honig of the Department of Defense for reporting this issue.
The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2008-4916 to this issue.
b. Windows-based host denial of service vulnerability in hcmon.sys
A vulnerability in an ioctl in hcmon.sys could be used to create a denial of service on a Windows-based host. This issue can only be exploited by a privileged Windows account.
VMware would like to thank Nikita Tarakanov for reporting this issue to us.
The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2009-1146 to this issue.
Note: newly released hosted products (see table in this section) address another potential denial of service in hcmon.sys as well.
Also this issue can only be exploited by a privileged Windows account.
The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2008-3761 to this issue.
c. A VMCI privilege escalation on Windows-based hosts or Windows- based guests.
The Virtual Machine Communication Interface (VMCI) is an infrastructure that provides fast and efficient communication between a virtual machine and the host operating system and between two or more virtual machines on the same host.
A vulnerability in vmci.sys could allow privilege escalation on Windows-based machines. This could occur on Windows-based hosts or inside Windows-based guest operating systems.
Current versions of ESX do not support the VMCI interface and hence they are not affected by this vulnerability.
Note: Installing the new hosted releases will not remediate the issue on Windows-based guests. The VMware Tools packages will need to be updated on each Windows-based guest followed by a reboot of the guest system.
VMware would like to thank Nikita Tarakanov for reporting this issue to us.
The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2009-1147 to this issue.
Refer to VMware KB article 1009826 on the steps that are needed to remediate this vulnerability on Windows-based hosts. This KB article is found at http://kb.vmware.com/kb/1009826.
d. VNnc Codec Heap Overflow vulnerabilities
The VNnc Codec assists in Record and Replay sessions. Record and Replay record the dynamic virtual machine state over a period of time.
Two heap overflow vulnerabilities could allow a remote attacker to execute arbitrary code on VMware hosted products. For an attack to be successful the user must be tricked into visiting a malicious web page or opening a malicious video file.
VMware would like to thank Aaron Portnoy from TippingPoint DVLabs for reporting these issues to us. TippingPoint has issued the following identifiers: ZDI-CAN-435, ZDI-CAN-436.
The Common Vulnerabilities and Exposures project (cve.mitre.org) has has assigned the names CVE-2009-0909 and CVE-2009-0910 to these issues.
e. ACE shared folders vulnerability
The VMware Host Guest File System (HGFS) shared folders feature allows users to transfer data between a guest operating system and the non-virtualized host operating system that contains it.
A vulnerability in ACE shared folders could allow a previously disabled and not removed shared folder in the guest to be enabled by a non ACE Administrator.
VMware would like to thank Emmanouel Kellinis, KPMG London, penetration testing team for reporting this issue to us.
The Common Vulnerabilities and Exposures project (cve.mitre.org) has has assigned the name CVE-2009-0908 to this issue.
f. A remote denial of service vulnerability in authd for Windows based hosts.
A vulnerability in vmware-authd.exe could cause a denial of service condition on Windows hosts.
The Common Vulnerabilities and Exposures Project (cve.mitre.org) has assigned the name CVE-2009-0177 to this issue.
g. VI Client Retains VirtualCenter Server Password in Memory
After logging in to VirtualCenter Server with VI Client, the password for VirtualCenter Server might be present in the memory of the VI Client.
Note: This vulnerability is present in VI Client and in order to remediate the vulnerability, you will need to replace VI Client with a fixed version (see below).
VMware would like to thank Craig Marshall for reporting this issue to us.
The Common Vulnerabilities and Exposures Project (cve.mitre.org) has assigned the name CVE-2009-0518 to this issue. |

|description||VMware products installed on the remote host are reportedly affected by multiple vulnerabilities :
- A vulnerability in the guest virtual device driver could allow an attacker to use the guest operating system to crash the host operating system. (CVE-2008-3761)
- A denial of service vulnerability affects an unspecified IOCTL contained in the 'hcmon.sys' driver. An attacker can exploit this in order to deny service on a Windows- based host. (CVE-2009-1146, CVE-2008-3761)
- A privilege escalation vulnerability affects the 'vmci.sys' driver on Windows-based machines. An attacker can exploit this in order to gain escalated privileges on either the host or the guest. (CVE-2009-1147)
- The 'VNnc' codec is affected by two heap-based buffer overflow vulnerabilities. An attacker can exploit these to execute arbitrary code on VMware hosted products by tricking a user into opening a malicious file.
- A vulnerability in ACE shared folder may allow attackers to enable previously disabled shared ACE folders. This only affects VMware ACE. (CVE-2009-0908)
- A remote denial of service vulnerability affects Windows hosts. An attacker can exploit this to crash the affected host. (CVE-2009-0177)
- A vulnerability in the virtual machine display function may allow a guest operating system to run code on the host. (CVE-2009-1244)
- A vulnerability in VMware Descheduled Time Accounting Service could be exploited to trigger a denial of service condition in Windows-based virtual machines. It should be noted that, this feature is optional, and the vulnerability can be exploited only if the feature is installed, and the affected service is not running in the virtual machine.
