[原文]VMware ESX Server 2.0.x before 2.0.2 and 2.x before 2.5.2 patch 4 stores authentication credentials in base 64 encoded format in the vmware.mui.kid and vmware.mui.sid cookies, which allows attackers to gain privileges by obtaining the cookies using attacks such as cross-site scripting (CVE-2005-3619).


[CNNVD]VMware ESX多个敏感信息泄露漏洞(CNNVD-200607-528)

        VMware ESX Server是一个适用于任何系统环境的企业级虚拟计算机软件。
        VMware ESX Server的管理界面使用了两个Cookies(vmware.mui.kid和vmware.mui.sid)中的会话ID。会话ID格式是私有的,包含有简单base64编码格式的用户帐号和口令。如果攻击者可以通过任何机制(如跨站脚本攻击)访问了Cookies的话,就可以获取认证凭据。
        VMware ESX Server的管理界面允许用户更改口令。如果是root用户的话,还可以更改其他用户的口令。在更改口令时,会通过一个HTML表单要求用户输入并确认新的口令,然后通过HTTP GET请求将数据发送给服务器。上述请求和口令都被记录在了Apache访问日志/var/log/httpd/access_log和/var/log/httpd/ssl_request_log中,并转存到了相应的备份日志中。上述文件都是完全可读的,因此本地用户可能浏览这些文件,获得使用管理界面设置的所有口令。

                   VMware Security Advisory

Advisory ID:       VMSA-2006-0004
Synopsis:          Cross site scripting vulnerability and other fixes
Knowledge base URL:http://kb.vmware.com/kb/2118366
Issue date:        2006-07-27
Updated on:        2006-07-27
CVE Names:         CVE-2005-3618 CVE-2005-3620 CVE-2006-2481
- -------------------------------------------------------------------

1. Summary:

Several security issues affecting ESX 2.5.x

VMware has rated this as a Priority 1 security issue according to 
Vmware's Security Response Policy. See
http://www.vmware.com/vmtn/technology/security/security_response.html

2. Relevant releases:

VMware ESX 2.5.3 prior to upgrade patch 2
VMware ESX 2.1.3 prior to upgrade patch 1
VMware ESX 2.0.2 prior to upgrade patch 1

3. Problem description:

The three vulnerabilities have been assigned names by the Common 
Vulnerabilities and Exposures (CVE) project, as follows:

CVE-2005-3618: An unauthorized user could potentially construct a 
specially crafted URL that may change a known user's password.

CVE-2005-3620: A local user could view potentially sensitive 
information.

CVE-2006-2481: If an attacker can gain access to browser cookies 
by any mechanism, such as through a cross site scripting attack, 
then they could acquire not only the session ID, but the 
authentication credentials. NOTE:  This issue was fixed in ESX 2.5.3, 
ESX 2.5.2 Patch 4, ESX 2.0.2 and later.

4. Solution:

Upgrade to the latest update package for your release of ESX. 
http://www.vmware.com/download/esx/

Installing the Update

This update requires you to boot your server into Linux mode to perform 
the upgrade. When you are prompted to reboot at the end of the upgrade, 
the installer will restart your system to run ESX Server.

   1. Power off all virtual machines and shutdown your server.
   2. Restart your system.
   3. At the LILO Boot Menu, select the linux option. Allow the system 
      start procedure to complete.
   4. Log in as root into the ESX Server service console, in Linux mode. 
      Make sure your path variable contains /usr/bin:/bin.
   5. Download the tar file into a temporary directory under /root on 
      your ESX service console.
   6. Change directories to that temporary directory.
   7. Verify the integrity of the package for your version:
      # md5sum esx-*-upgrade.tar.gz

      The md5 checksum output should match one of the following:
	50c3260176c8cc33ad3bc880a20a4656 esx-2.5.3-28065-upgrade.tar.gz 
	ddb67afe2a48a04fb764af2497d6b75c esx-2.5.3-27728-upgrade.tar.gz 
	ce112a1d17893fbe5b47dfb011468269 esx-2.1.3-27733-upgrade.tar.gz 
	7f9b2367bbc54f29586ade0e1e286837 esx-2.0.2-27920-upgrade.tar.gz 

   8. Extract the compressed tar archive:
      # tar -xvzf esx-2.5.3-28065-upgrade.tar.gz
   9. Change directories to the newly created directory 
      # cd esx-2.5.3-28065-upgrade
  10. Run the patch installer:
      # /usr/bin/perl ./upgrade.pl

      Note: Once you start the installation script, do not enter keyboard 
            escape commands such as Control-C or Control-D. Using escape 
            commands will interrupt the upgrade procedure and leave your 
            system partially upgraded.

  11. The system updates have now been installed. A reboot prompt displays:
      Reboot the server now [y/n]?

      This update will not be complete until you reboot the ESX Server. If 
      you enter N, to indicate that you will not reboot at this time, ESX 
      Server displays the warning message: 

      "Please reboot the server manually for this update to take effect. 
       Update has been terminated unexpectedly." 

      If you see this message, you must manually reboot the server to complete 
      the driver update.

  12. At the reboot prompt, enter Y to reboot the server.

Corsaire Security Advisory - The VMware ESX Server product will allow a local attacker to gain access to users' (including root's) passwords under certain conditions via a cookie issue.

-- Corsaire Security Advisory --

Title: VMware ESX Server Password Disclosure in Cookie issue
Date: 12.05.06
Application: VMware ESX prior to 2.5.2 patch 4
             VMware ESX prior to 2.0.2
Environment: VMware ESX
Author: Martin O'Neal [martin.oneal@corsaire.com]
Audience: General distribution
Reference: c060512-001


-- Scope --

The aim of this document is to clearly define an issue that exists with 
the VMware ESX Server product [1] that will allow a local attacker to 
gain access to users' (including root's) passwords under certain 
conditions.


-- History --

Discovered: 12.05.06 (Martin O'Neal)
Vendor notified: 19.05.06
Document released: 31.07.06


-- Overview --

VMware ESX Server is described [1] as virtual infrastructure software 
for partitioning, consolidating and managing servers in mission-critical 
environments.
 
The software provides a virtualization layer that allows multiple x86 
based operating systems to run on the same hardware concurrently.  The 
ESX Server product differs from other VMware products in that it does 
not require a "host" operating system to be provided by the user.  
Instead, it uses a custom x86 kernel as the host, along with a 
customised Linux operating system as a "console O/S". 

VMware ESX Server includes a number of network services and a web 
application, called the "VMware Management Interface" that can be used 
to perform remote administration of the system. 


-- Analysis --

The Management Interface is a traditional web application, which 
utilises a session ID contained within two cookies; vmware.mui.kid and 
vmware.mui.sid.  The Session ID format is proprietary and contains the 
user account and password in a simple (recursively) base64 encoded 
format.

If an attacker can gain access to the cookies by any mechanism, such as 
through a simple cross site scripting attack, then they will acquire not 
only the session ID, but the authentication credentials as well.


-- Recommendations --

Upgrade to a version of the VMware ESX product that does not exhibit 
this issue.


-- CVE --

The Common Vulnerabilities and Exposures (CVE) project has assigned the 
name CVE-2006-2481 to this issue.  This is a candidate for inclusion in 
the CVE list (http://cve.mitre.org), which standardises names for 
security problems.

- 漏洞讨论

VMware ESX is prone to multiple information-disclosure vulnerabilities. These issues are due to a design error in the application. The following issues were reported:

1. An information disclosure vulnerability that could disclose the session ID, username, and password if an attacker can access session cookies used by the management interface.

2. An information disclosure vulnerability that could expose authentication credentials to local users on the computer hosting the VMWare ESX Server. This vulnerability occurs because authentication credentials are also handled insecurely by the VMWare ESX management interface.

VMware ESX server versions 2.5.3 P2, 2.1.3 P1, 2.0.2, 2.0.2 P1, and 2.5.2 P4 are reported to be vulnerable; other versions may also be affected.

- 漏洞利用

Attackers can exploit this issue using a web browser application.
