One of the most dangerous vulnerabilities in Office documents in 2012 was CVE-2012-0158. #Microsoft monthview control 6.0 download download#The administrator must forcibly tighten the settings by prohibiting the download of any ActiveX controls (note, however, that in the safe viewing mode, ActiveX is not loaded). Vulnerabilities in the latter are especially dangerous - the default settings that are set when the application is installed do not imply any protection against downloading these elements or a warning to the user. However, VBA is not required to load and activate them, and user permission is not required to load items from the white list. Embedding in Office documents, however, is still possible.ĪctiveX documents are intended to be used in conjunction with Visual Basic for Applications. New browser Microsoft Edge finally broke up with this relic of the past. Browsers from other manufacturers almost immediately abandoned support for ActiveX. The embedded ActiveX web pages represented a well-known security hole in Internet Explorer, and security measures increased over time. Once a good idea seemed to create such controls universal, with the possibility of use in any application, and put them for this purpose in the components of COM. OLE Embedded Objects ( OLE Embedded Objects )ĪctiveX controls can be thought of as elements of the program window - say, buttons, switches, lists, input fields, and other forms - designed to produce some events or respond to events. #Microsoft monthview control 6.0 download code#This article will look at embedding objects in Microsoft Office documents (or rather, only the security aspect) in the context of the data and code loaded into memory at runtime.įormally embedded objects in Microsoft Office documents can be divided into the following groups: The “disk” representation of the master document is a CFBF file. From a security point of view, these elements are somewhat less interesting than the elements that (mostly) are discussed in the article - elements that use external application code added to documents using OLE. Subsequently, the applications of the package received a fairly rich set of tools for adding images, charts and diagrams to documents, controls that are created and processed by the application itself and are part of it. "The bad news" was that versatile way to add in these documents (and the processing of these data code) became universal by the appearance of the product vulnerabilities, which is still constantly presents pleasant surprises creators of malware security researchers. In those days, the idea of “seamless” merging in one document of data of various formats seemed attractive and fascinating, and before identifying the first problems, had time to firmly grow into many large-scale products. Initially, Microsoft Office architecture was based on the concept of composite documents, they are also OLE documents, actively promoted by Microsoft at the dawn of 32-bit Windows.
