According to the CVSS metric, user interaction is required (UI:R). What interaction would the user have to do? Exploitation of the vulnerability requires that a user open a specially crafted file with an affected version of Microsoft Excel. In an email attack scenario, an attacker could exploit the vulnerability by sending the specially crafted file to the user and convincing the user to open the file. In a web-based attack scenario, an attacker could host a website (or leverage a compromised website that accepts or hosts user-provided content) containing a specially crafted file designed to exploit the vulnerability. An attacker would have no way to force users to visit the website. Instead, an attacker would have to convince users to click a link, typically by way of an enticement in an email or instant message, and then convince them to open the specially crafted file. According to the CVSS metric, privileges required is low (PR:L). What does that mean for this vulnerability? Successful exploitation of this vulnerability requires an attacker to have access to the location where the target file will be run. They would then need to plant a specific file that would be used as part of the exploitation. What kind of security feature could be bypassed by successfully exploiting this vulnerability? An attacker who successfully exploited this could bypass The Packager Object Filters feature. Is the Preview Pane an attack vector for this vulnerability? No, the Preview Pane is not an attack vector.
