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.

Trusted locations specified in the Trust Center are used to define file locations assumed to be safe. Content, code, and add-ins are allowed to load from trusted locations with a minimal amount of security, without prompting the users for permission. If a dangerous file is opened from a trusted location, it will not be subject to standard security measures and could harm users' computers or data. By default, files located in trusted locations (those specified in the Trust Center) are assumed to be safe.

InfoPath automatically redirects user requests for sites that have not been upgraded to the temporary URL if it is located on the local intranet, but blocks them if the temporary URL is located elsewhere. InfoPath will prompt users before redirecting forms or form templates to another intranet site. If this restriction is relaxed, all requests to sites that have not been upgraded will be redirected to their targets, regardless of location. This functionality could cause requests made to a secure site to be redirected to an unsecured one (for example, requests to an intranet site could be redirected to an unencrypted Internet site), causing sensitive information to be at risk.

InfoPath users can choose whether to allow trusted forms to run on their computers. The Full Trust security level allows a form to access local system resources, such as COM components or files on users' computers, and suppresses certain security prompts. It can only be used with forms that are installed on users' computers or with forms using a form template that is digitally signed with a trusted root certificate. As with any security model that allows trusted entities to operate with fewer security controls, if a form with malicious content is marked as fully trusted it could be used to compromise information security or affect users' computers.

Users can attach any type of file to forms except potentially unsafe files that might contain viruses, such as .bat or .exe files. For the full list of file types that InfoPath disallows by default, see "Security Details" in Insert a file attachment control on the Microsoft Office Online website. If unsafe file types are added to InfoPath forms, they might be used as a means of attacking the computer on which the form is opened. These unsafe file types may include active content, or may introduce other vulnerabilities that an attacker can exploit.

InfoPath makes it possible to host InfoPath forms in other applications as ActiveX controls. Such controls are known as InfoPath form controls. A malicious user could insert a web beacon into one of these controls which could be used to contact an external server when the user opens the form. Information could be gathered by the form, or information entered by users could be sent to an external server and expose the internal systems to additional attacks. By default, InfoPath form controls warn users about potential web beaconing threats.

InfoPath allows users to attach form templates when sending email forms. If users are able to open form templates included with email forms, rather than using a cached version that is previously published, an attacker could send a malicious form template with the email form in an attempt to gain access to sensitive information.

By default, InfoPath 2007 caches form templates when they are attached to a mail item that is recognized as an InfoPath e-mail form. When users fill out forms that open with a restricted security level, InfoPath uses the cached version of the mailed template, rather than any published version. To circumvent users filling out a published form, an attacker could e-mail an alternate version of the form, which would return the data to the sender as part of a phishing attack and could be used to gain access to confidential information.

InfoPath provides three security levels for form templates: Restricted, Domain, and Full Trust. The security levels determine whether a form template can access data on other domains, or access files and settings on your computer. Fully trusted forms have a Full Trust security level, and can access files and settings on users' computers. The form template for these forms must be digitally signed with a trusted root certificate, or installed on users' computers. By default, InfoPath can open email forms with full trust. If an attacker designs and sends a dangerous fully trusted email form, it could affect users' computers or give the attacker access to sensitive information.

Attackers can send users InfoPath email forms in an attempt to gain access to confidential information. Depending on the level of trust of the forms, it might also be possible to gain access to other data automatically. By default, Outlook 2013 uses the InfoPath email forms feature to render forms in Outlook and allows users to fill them out in place.

When InfoPath solutions are opened locally, the location of the form is checked so that updates to the form can be downloaded. If a user saves a form locally from a location on the Internet and then opens the same form from another location on the Internet, the cache will be updated with the new location information. If the user then opens the first form from its saved location, there will be a mismatch between the locally saved form and the locally cached form. This situation would typically happen when developers move forms to a new location, but if there is no warning when the cached location is used, it could be misused by an attacker attempting to redirect the forms to a new location. This type of attack is a form of beaconing. By default, if the location information in the cached form and the saved form to not match, the form cannot be opened without prompting the user for consent.

This setting controls whether or not the user sees a dialog box when opening Microsoft InfoPath forms containing digitally signed content. By default, InfoPath shows the user a warning message when the form contains a digital signature. By being aware of a digitally signed form, the user will be able to check the validity of the signature. Otherwise, the forms may have been maliciously modified and will be invalidated.

InfoPath 2013 forms' business logic can only call into Global Assembly Cache (GAC) assemblies listed in the APTCA Assembly Allowable List. If this configuration is changed, forms can call into any assembly in the GAC where the Allow Partially Trusted Callers Attribute (APTCA) is set. This configuration could allow malicious developers to access assemblies in the GAC not intended to be used by InfoPath forms.

Security flaws with software applications are discovered daily. Vendors are constantly updating and patching their products to address newly discovered security vulnerabilities. Organizations (including any contractor to the organization) are required to promptly install security-relevant software updates (e.g., patches, service packs, and hot fixes). Flaws discovered during security assessments, continuous monitoring, incident response activities, or information system error handling must also be addressed expeditiously. Organization-defined time periods for updating security-relevant software may vary based on a variety of factors including, for example, the security category of the information system or the criticality of the update (i.e., severity of the vulnerability related to the discovered flaw). This requirement will apply to software patch management solutions that are used to install patches across the enclave and also to applications themselves that are not part of that patch management solution. For example, many browsers today provide the capability to install their own patch software. Patch criticality, as well as system criticality will vary. Therefore, the tactical situations regarding the patch management process will also vary. This means that the time period used must be a configurable parameter. Time frames for application of security-relevant software updates may be dependent upon the Information Assurance Vulnerability Management (IAVM) process. The application will be configured to check for and install security-relevant software updates within an identified time period from the availability of the update. The specific time period will be defined by an authoritative source (e.g., IAVM, CTOs, DTMs, and STIGs).
