A malicious user might use this URL syntax to create a hyperlink that appears to open a legitimate Website but actually opens a deceptive (spoofed) Website. 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.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility>System Administrator</Responsibility><Responsibility>Information Assurance Officer</Responsibility><IAControls></IAControls>DPMS Target Microsoft Visio 2013DISA FSODPMS TargetMicrosoft Visio 20132486CCI-000366Set the policy value for Computer Configuration -> Administrative Templates -> Microsoft Office 2013 (Machine) -> Security Settings -> IE Security "Disable user name and password" to "Enabled" and place check in 'visio.exe' check box.DTOO111 - IE Bind to Object<GroupDescription></GroupDescription>DTOO111The Internet Explorer Bind to Object functionality must be enabled.<VulnDiscussion>Internet Explorer performs a number of safety checks before initializing an ActiveX control. It will not initialize a control if the kill bit for the control is set in the registry, or if the security settings for the zone in which the control is located do not allow it to be initialized.
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). A security risk could occur if potentially dangerous controls are allowed to load.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility>System Administrator</Responsibility><Responsibility>Information Assurance Officer</Responsibility><IAControls></IAControls>DPMS Target Microsoft Visio 2013DISA FSODPMS TargetMicrosoft Visio 20132486CCI-000366Set the policy value for Computer Configuration -> Administrative Templates -> Microsoft Office 2013 (Machine) -> Security Settings -> IE Security "Bind to object" to "Enabled" and place check in 'visio.exe' check box.DTOO117 - Saved from URL<GroupDescription></GroupDescription>DTOO117The Saved from URL mark must be selected to enforce Internet zone processing.<VulnDiscussion>Typically, when Internet Explorer loads a web page from a Universal Naming Convention (UNC) share that contains a Mark of the Web (MOTW) comment, indicating the page was saved from a site on the Internet; Internet Explorer runs the page in the Internet security zone instead of the less restrictive Local Intranet security zone. 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 Internet Explorer does not evaluate the page for a MOTW, potentially dangerous code could be allowed to run.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility>System Administrator</Responsibility><Responsibility>Information Assurance Officer</Responsibility><IAControls></IAControls>DPMS Target Microsoft Visio 2013DISA FSODPMS TargetMicrosoft Visio 20132486Set the policy value for Computer Configuration -> Administrative Templates -> Microsoft Office 2013 (Machine) -> Security Settings -> IE Security "Saved from URL" to "Enabled" and place check in 'visio.exe' check box.DTOO123 - Block Navigation to URL from Office <GroupDescription></GroupDescription>DTOO123Navigation to URLs embedded in Office products must be blocked.<VulnDiscussion>To protect users from attacks, Internet Explorer usually does not attempt to load malformed URLs. 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 Internet Explorer attempts to load a malformed URL, a security risk could occur.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility>System Administrator</Responsibility><Responsibility>Information Assurance Officer</Responsibility><IAControls></IAControls>DPMS Target Microsoft Visio 2013DISA FSODPMS TargetMicrosoft Visio 20132486CCI-000366Set the policy value for Computer Configuration -> Administrative Templates -> Microsoft Office 2013 (Machine) -> Security Settings -> IE Security "Navigate URL" to "Enabled" and 'visio.exe' is checked.DTOO124 - Scripted Window Security<GroupDescription></GroupDescription>DTOO124Scripted Window Security must be enforced.<VulnDiscussion>Malicious websites often try to confuse or trick users into giving a site permission to perform an action allowing the site to take control of the users' computers in some manner. Disabling or not configuring this setting allows unknown websites to:
-Create browser windows appearing to be from the local operating system.
-Draw active windows displaying outside of the viewable areas of the screen capturing keyboard input.
-Overlay parent windows with their own browser windows to hide important system information, choices or prompts.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility>System Administrator</Responsibility><Responsibility>Information Assurance Officer</Responsibility><IAControls></IAControls>DPMS Target Microsoft Visio 2013DISA FSODPMS TargetMicrosoft Visio 20132486CCI-000366Set the policy value for Computer Configuration -> Administrative Templates -> Microsoft Office 2013 (Machine) -> Security Settings -> IE Security "Scripted Window Security Restrictions" to "Enabled" and 'visio.exe' is checked.DTOO126 - Add-on Management<GroupDescription></GroupDescription>DTOO126Add-on Management functionality must be allowed.<VulnDiscussion>Internet Explorer add-ons are pieces of code, run in Internet Explorer, to provide additional functionality. Rogue add-ons may contain viruses or other malicious code. Disabling or not configuring this setting could allow malicious code or users to become active on user computers or the network. For example, a malicious user can monitor and then use keystrokes users type into Internet Explorer. Even legitimate add-ons may demand resources, compromising the performance of Internet Explorer, and the operating systems for user computers.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility>System Administrator</Responsibility><Responsibility>Information Assurance Officer</Responsibility><IAControls></IAControls>DPMS Target Microsoft Visio 2013DISA FSODPMS TargetMicrosoft Visio 20132486CCI-000366Set the policy value for Computer Configuration -> Administrative Templates -> Microsoft Office 2013 (Machine) -> Security Settings -> IE Security "Add-on Management" to "Enabled" and place check in 'visio.exe' check box.DTOO127 - Add-ins are signed by Trusted Publisher<GroupDescription></GroupDescription>DTOO127Add-ins to Office applications must be signed by a Trusted Publisher.<VulnDiscussion>Office 2013 applications do not check the digital signature on application add-ins before opening them. Disabling or not configuring this setting may allow an application to load a dangerous add-in. As a result, malicious code could become active on user computers or the network.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility>System Administrator</Responsibility><Responsibility>Information Assurance Officer</Responsibility><IAControls></IAControls>DPMS Target Microsoft Visio 2013DISA FSODPMS TargetMicrosoft Visio 20132486CCI-000366Set the policy value for User Configuration -> Administrative Templates -> Microsoft Visio 2013 -> Visio Options -> Security -> Trust Center -> "Require that application add-ins are signed by Trusted Publisher" to "Enabled".DTOO129 - Block Pop-Ups<GroupDescription></GroupDescription>DTOO129Links that invoke instances of IE from within an Office product must be blocked.<VulnDiscussion>The Pop-up Blocker feature in Internet Explorer can be used to block most unwanted pop-up and pop-under windows from appearing. 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 the Pop-up Blocker is disabled, disruptive and potentially dangerous pop-up windows could load and present a security risk.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility>System Administrator</Responsibility><Responsibility>Information Assurance Officer</Responsibility><IAControls></IAControls>DPMS Target Microsoft Visio 2013DISA FSODPMS TargetMicrosoft Visio 20132486CCI-000366Set the policy value for Computer Configuration -> Administrative Templates -> Microsoft Office 2013 (Machine) -> Security Settings -> IE Security "Block popups" to "Enabled" and place check in 'visio.exe' check box.DTOO131 - Trust Bar Notifications<GroupDescription></GroupDescription>DTOO131Trust Bar Notifications for unsigned applications must be disabled.<VulnDiscussion>If an application is configured to require all add-ins to be signed by a trusted publisher, any unsigned add-ins the application loads will be disabled and the application will display the Trust Bar at the top of the active window. The Trust Bar contains a message informing users about the unsigned add-in. If a user is allowed to make the determination to allow an unsigned add-in, it increases the risk of malicious code being introduced onto the user's computer or the network.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility>System Administrator</Responsibility><Responsibility>Information Assurance Officer</Responsibility><IAControls></IAControls>DPMS Target Microsoft Visio 2013DISA FSODPMS TargetMicrosoft Visio 20132486CCI-000366Set the policy value for User Configuration -> Administrative Templates -> Microsoft Visio 2013 -> Visio Options -> Security -> Trust Center -> "Disable Trust Bar Notification for unsigned application add-ins and block them" to "Enabled".DTOO132 - Restrict File Download<GroupDescription></GroupDescription>DTOO132File downloads must be configured for proper restrictions.<VulnDiscussion>Disabling this setting allows websites to present file download prompts via code without the user specifically initiating the download. User preferences may also allow the download to occur without prompting or interaction with the user. Even if Internet Explorer prompts the user to accept the download, some websites abuse this functionality. Malicious websites may continually prompt users to download a file or present confusing dialog boxes to trick users into downloading or running a file. If the download occurs and it contains malicious code, the code could become active on user computers or the network.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility>System Administrator</Responsibility><Responsibility>Information Assurance Officer</Responsibility><IAControls></IAControls>DPMS Target Microsoft Visio 2013DISA FSODPMS TargetMicrosoft Visio 20132486CCI-000366Set the policy value for Computer Configuration -> Administrative Templates -> Microsoft Office 2013 (Machine) -> Security Settings -> IE Security "Restrict File Download" to "Enabled" and 'visio.exe' is checked.DTOO209 - Zone Elevation Protection<GroupDescription></GroupDescription>DTOO209Protection from zone elevation must be enforced.<VulnDiscussion>Internet Explorer places restrictions on each web page users can use the browser to open. Web pages on a user's local computer have the fewest security restrictions and reside in the Local Machine zone, making this security zone a prime target for malicious users and code. Disabling or not configuring this setting could allow pages in the Internet zone to navigate to pages in the Local Machine zone to then run code to elevate privileges. This could allow malicious code or users to become active on user computers or the network.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility>System Administrator</Responsibility><Responsibility>Information Assurance Officer</Responsibility><IAControls></IAControls>DPMS Target Microsoft Visio 2013DISA FSODPMS TargetMicrosoft Visio 20132486Set the policy value for Computer Configuration -> Administrative Templates -> Microsoft Office 2013 (Machine) -> Security Settings -> IE Security "Protection From Zone Elevation" to "Enabled" and 'visio.exe' is checked.DTOO211 - Restrict ActiveX Install<GroupDescription></GroupDescription>DTOO211ActiveX installs must be configured for proper restrictions.<VulnDiscussion>Microsoft ActiveX controls allow unmanaged, unprotected code to run on the user computers. ActiveX controls do not run within a protected container in the browser like the other types of HTML or Microsoft Silverlight-based controls. Disabling or not configuring this setting does not block prompts for ActiveX control installations and these prompts display to users. This could allow malicious code to become active on user computers or the network.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility>System Administrator</Responsibility><Responsibility>Information Assurance Officer</Responsibility><IAControls></IAControls>DPMS Target Microsoft Visio 2013DISA FSODPMS TargetMicrosoft Visio 20132486CCI-000366Set the policy value for Computer Configuration -> Administrative Templates -> Microsoft Office 2013 (Machine) -> Security Settings -> IE Security "Restrict ActiveX Install" to "Enabled" and 'visio.exe' is checked.DTOO304 - VBA Macro Warning settings<GroupDescription></GroupDescription>DTOO304Warning Bar settings for VBA macros must be configured.<VulnDiscussion>When users open files containing VBA Macros, applications open the files with the macros disabled and displays the Trust Bar with a warning that macros are present and have been disabled. Users may then enable these macros by clicking Options on the Trust Bar and selecting the option to enable them. Disabling or not configuring this setting may allow dangerous macros to become active on user computers or the network.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility>System Administrator</Responsibility><Responsibility>Information Assurance Officer</Responsibility><IAControls></IAControls>DPMS Target Microsoft Visio 2013DISA FSODPMS TargetMicrosoft Visio 20132486CCI-000366Set the policy value for User Configuration -> Administrative Templates -> Microsoft Visio 2013 -> Visio Options -> Security -> Trust Center -> "VBA Macro Notification Settings" to "Enabled: Disable all with notification".DTOO305 - UI extending from documents and templates<GroupDescription></GroupDescription>DTOO305Visio 2013 application must be prevented from loading any custom user interface (UI) code.<VulnDiscussion>This policy setting controls whether Office 2013 applications load any custom user interface (UI) code included with a document or template. Office 2013 allows developers to extend the UI with customization code that is included in a document or template. If this policy setting is enabled, Office 2013 applications cannot load any UI customization code included with documents and templates. If this policy setting is disabled or not configured, Office 2013 applications load any UI customization code included with a document or template when opening it, leaving the Office 2013 application susceptible to malicious code.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility>System Administrator</Responsibility><Responsibility>Information Assurance Officer</Responsibility><IAControls></IAControls>DPMS Target Microsoft Visio 2013DISA FSODPMS TargetMicrosoft Visio 20132486CCI-000366Set the policy value for User Configuration -> Administrative Templates -> Microsoft Office 2013 -> Global Options -> Customize -> "Disable UI extending from documents and templates" to "Enabled".
