Common Weakness Enumeration (CWE)
Common Attack Pattern Enumeration and Classification (CAPEC)
- 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
- Blue Boxing
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.

|description||a. A privilege escalation on 32-bit and 64-bit guest operating systems VMware products emulate hardware functions and create the possibility to run guest operating systems. A flaw in the CPU hardware emulation might allow the virtual CPU to incorrectly handle the Trap flag. Exploitation of this flaw might lead to a privilege escalation on guest operating systems. An attacker needs a user account on the guest operating system and have the ability to run applications. VMware would like to thank Derek Soeder for discovering this issue and working with us on its remediation. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2008-4915 to this issue. b. Directory traversal vulnerability VirtualCenter allows administrators to have fine-grained privileges. A directory traversal vulnerability might allow administrators to increase these privileges. In order to leverage this flaw, the administrator would need to have the Datastore.FileManagement privilege. VMware would like to thank Michel Toussaint for reporting this issue to us. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2008-4281 to this issue.|

|description||A VMware product installed on the remote host is affected by multiple vulnerabilities : - A CPU hardware emulation flaw in certain VMware products could allow a virtual CPU to incorrectly handle a Trap flag. Successful exploitation of this issue could lead to privilege escalation on the guest operating system. An attacker would need an account on the guest operating system and the ability to run applications to exploit this issue. (CVE-2008-4915) - By sending a malicious request from the guest operating system to the virtual hardware, it may be possible to cause the virtual hardware to write to an uncontrolled section in the physical memory. (CVE-2008-4917)|

|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. Impact : 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). Workaround : There is no known workaround at this time.|

|description||BUGTRAQ ID: 32168 CVE(CAN) ID: CVE-2008-4915 VMWare是一款虚拟PC软件，允许在一台机器上同时运行两个或多个Windows、DOS、LINUX系统。 VMWare在处理指令的执行时存在问题，攻击者可能利用此漏洞提升自己的权限。如果在设置了Trap Flag的情况下出现中断，正确的CPU将执行转移到中断处理器之前会清除Trap Flag。对于受影响的VMware版本，如果内核态IRET设置了Trap Flag的话，则在执行单字节INT 3指令的时候Trap Flag在模式切换后仍继续存在，这造成的结果就是如果能够导致内核通过IRET设置Trap Flag的话，用户态代码在遇到INT 3断点（#BP）处理器的第一个指令的话会导致出现单步调试trap（#DB）。 VMWare Workstation 6.0.x VMWare Workstation 5.x VMWare ACE 2.0.x VMWare ACE 1.x VMWare Player 2.0.x VMWare Player 1.x VMWare Server 1.x VMWare ESX 3.5 VMWare ESX
