Vulnerability discussion

The Uniform Resource Locator (URL) standard allows user authentication to be included in URL strings in the form http://username:password@example.com. A malicious user might use this URL syntax to create a hyperlink that appears to open a legitimate Web site but actually opens a deceptive (spoofed) Web site. For example, the URL http://www.wingtiptoys.com@example.com appears to open http://www.wingtiptoys.com but actually opens http://example.com. To protect users from such attacks, Internet Explorer usually blocks any URLs using this syntax.This functionality can be controlled separately for instances of Internet Explorer spawned by Office applications (for example, if a user clicks a link in an Office document or selects a menu option that loads a Web page). If user names and passwords in URLs are allowed, users could be diverted to dangerous Web pages, which could pose a security risk.

Check content

The policy value for Computer Configuration -> Administrative Templates -> Microsoft Office 2010 (Machine) -> Security Settings -> IE Security “Disable user name and password” must be “Enabled” and a check in the ‘onent.exe’ check box must be present. Procedure: Use the Windows Registry Editor to navigate to the following key: HKLM\Software\Microsoft\Internet Explorer\Main\FeatureControl\FEATURE_HTTP_USERNAME_PASSWORD_DISABLE Criteria: If the value onenote.exe is REG_DWORD = 1, this is not a finding.

Fix text

Set the policy value for Computer Configuration -> Administrative Templates -> Microsoft Office 2010 (Machine) -> Security Settings -> IE Security “Disable user name and password” to “Enabled” and place a check in the ‘onent.exe’ check box.
