Microsoft Excel Malformed SELECTION record Vulnerability - CVE-2006-1301

A remote code execution vulnerability exists in Excel that results from the processing of a malformed SELECTION record. An attacker could exploit the vulnerability by constructing a specially crafted Excel file that could allow remote code execution.

If a user were logged on with administrative user rights, an attacker who successfully exploited this vulnerability could take complete control of an affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. Users whose accounts are configured to have fewer user rights on the system could be less affected than users who operate with administrative user rights.

Mitigating Factors for Microsoft Excel Malformed SELECTION record Vulnerability - CVE-2006-1301:

  • An attacker who successfully exploited this vulnerability could gain the same user rights as the local user. Users whose accounts are configured to have fewer user rights on the system could be less impacted than users who operate with administrative user rights.
  • On Outlook 2002 and Outlook 2003, the vulnerability could not be exploited automatically through e-mail. For an attack to be successful a user must accept a prompt confirming that they Open, Save or Cancel the attachment that is sent in an e-mail message before the exploit could occur.
  • In a Web-based attack scenario, an attacker could host a Web site that contains a Web page that is used to exploit this vulnerability. In addition, compromised Web sites and Web sites that accept or host user-provided content or advertisements could contain specially crafted content that could exploit this vulnerability. In all cases, however, an attacker would have no way to force users to visit these Web sites. Instead, an attacker would have to persuade users to visit the Web site, typically by getting them to click a link in an e-mail message or instant messenger message that takes users to the attacker's Web site.

Note Office 2000 does not prompt the user to Open, Save, or Cancel before opening a document.

Workarounds for Microsoft Excel Malformed SELECTION record Vulnerability - CVE-2006-1301:

Microsoft has tested the following workarounds. While these workarounds will not correct the underlying vulnerability, they help block known attack vectors. When a workaround reduces functionality, it is identified in the following section.
