Summary

Microsoft Office Excel 2007 Gold and SP1 does not properly delete the PWD (password) string from connections.xml when a .xlsx file is configured not to save the remote data session password, which allows local users to obtain sensitive information and obtain access to a remote data source, aka the "Excel Credential Caching Vulnerability."

Common Weakness Enumeration (CWE)

Common Attack Pattern Enumeration and Classification (CAPEC)

  • Buffer Overflow via Environment Variables
    This attack pattern involves causing a buffer overflow through manipulation of environment variables. Once the attacker finds that they can modify an environment variable, they may try to overflow associated buffers. This attack leverages implicit trust often placed in environment variables.
  • Server Side Include (SSI) Injection
    An attacker can use Server Side Include (SSI) Injection to send code to a web application that then gets executed by the web server. Doing so enables the attacker to achieve similar results to Cross Site Scripting, viz., arbitrary code execution and information disclosure, albeit on a more limited scale, since the SSI directives are nowhere near as powerful as a full-fledged scripting language. Nonetheless, the attacker can conveniently gain access to sensitive files, such as password files, and execute shell commands.
  • Cross Zone Scripting
    An attacker is able to cause a victim to load content into their web-browser that bypasses security zone controls and gain access to increased privileges to execute scripting code or other web objects such as unsigned ActiveX controls or applets. This is a privilege elevation attack targeted at zone-based web-browser security. In a zone-based model, pages belong to one of a set of zones corresponding to the level of privilege assigned to that page. Pages in an untrusted zone would have a lesser level of access to the system and/or be restricted in the types of executable content it was allowed to invoke. In a cross-zone scripting attack, a page that should be assigned to a less privileged zone is granted the privileges of a more trusted zone. This can be accomplished by exploiting bugs in the browser, exploiting incorrect configuration in the zone controls, through a cross-site scripting attack that causes the attackers' content to be treated as coming from a more trusted page, or by leveraging some piece of system functionality that is accessible from both the trusted and less trusted zone. This attack differs from "Restful Privilege Escalation" in that the latter correlates to the inadequate securing of RESTful access methods (such as HTTP DELETE) on the server, while cross-zone scripting attacks the concept of security zones as implemented by a browser.
  • Cross Site Scripting through Log Files
    An attacker may leverage a system weakness where logs are susceptible to log injection to insert scripts into the system's logs. If these logs are later viewed by an administrator through a thin administrative interface and the log data is not properly HTML encoded before being written to the page, the attackers' scripts stored in the log will be executed in the administrative interface with potentially serious consequences. This attack pattern is really a combination of two other attack patterns: log injection and stored cross site scripting.
  • Command Line Execution through SQL Injection
    An attacker uses standard SQL injection methods to inject data into the command line for execution. This could be done directly through misuse of directives such as MSSQL_xp_cmdshell or indirectly through injection of data into the database that would be interpreted as shell commands. Sometime later, an unscrupulous backend application (or could be part of the functionality of the same application) fetches the injected data stored in the database and uses this data as command line arguments without performing proper validation. The malicious data escapes that data plane by spawning new commands to be executed on the host.

descriptionMicrosoft Office Excel 2007 Gold and SP1 does not properly delete the PWD (password) string from connections.xml when a .xlsx file is configured not to save the remote data session password, which allows local users to obtain sensitive information and obtain access to a remote data source, aka the "Excel Credential Caching Vulnerability."

descriptionBUGTRAQ ID: 30641 CVE(CAN) ID: CVE-2008-3003 Excel是Microsoft Office办公软件套件中的电子表格工具。 Excel在实现访问认证时存在漏洞,如果.xlsx文件配置为不保存远程数据会话口令的话,Excel就无法正确地从connections.xml删除PWD字符串,这允许用户获得敏感信息并获得对远程数据源的访问。 Microsoft Excel 2007 SP1 Microsoft Excel 2007 Microsoft Office 2008 for Mac 临时解决方法: * 在.xlsx文件内编辑connections .xml,然后手动删除密码 Windows Shell方法: 1. 编辑之前先创建一个受影响的.xlsx文件的备份副本。 2. 在Windows XP或Windows Vista计算机上,将受影响的.xlsx文件的文件扩展名更改为.zip。 3. 使用Windows资源管理器,双击ZIP文件打开,然后双击xl文件夹。 4. 在xl文件夹中,单击“connections.xml”,然后将其从ZIP文件拖出到本地文件夹或桌面。 5. 使用鼠标右键单击“connections.xml”文件时将出现一个快捷菜单。在菜单中,单击“打开方式”,然后选择“记事本”。 6. 在记事本中,找到字符串“connection=”,然后在该字符串中搜索“PWD =”。删除“PDW=”之后和“;”之前的任何字符,因为这些字符是未正确保存的连接凭据。 7. 保存connections.xml文件,然后关闭记事本。 8. 将connections.xml文件拖回到ZIP文件夹,确保其放置在ZIP文件的xl文件夹中。 9. 将ZIP文件的文件扩展名改回为原来的.xlsx。 10. 在Excel 2007中打开文档,单击“数据”菜单,然后单击功能区连接部分中的“全部刷新”。请确认系统是否提示您输入密码。 * 使用Excel 2007通过数据连接加密文件 1. 在Excel 2007中打开包含保存的数据连接的.xlsx文件 2. 单击“Microsoft Office按钮”,指向“准备”,然后单击“加密文档”。 3. 键入密码(最多255个字符)。默认下,将使用AES 128位加密来加密文档内容(使用密码作为加密密钥) * 在Excel 2007中,以Excel 97-2003文件格式保存此文件。 1. 在Excel 2007中打开包含保存的数据连接的.xlsx文件 2. 单击“Microsoft Office按钮”,指向“另存为”,然后单击“Excel 97-2003工作簿” 3. 为工作簿键入文件名,然后按“保存”按钮 厂商补丁: Microsoft --------- Microsoft已经为此发布了一个安全公告(MS08-043)以及相应补丁: MS08-043:Vulnerabilities in Microsoft Excel Could Allow Remote Code Execution (954066) 链接:<a href=http://www.microsoft.com/technet/security/Bulletin/MS08-043.mspx?pf=true target=_blank>http://www.microsoft.com/technet/security/Bulletin/MS08-043.mspx?pf=true</a>
