Luckily, Microsoft says that the Outlook preview pane cannot be used as an attack vector in exploitation attempts targeting this vulnerability. To successfully exploit this critical vulnerability, attackers would have to trick their targets into opening a specially crafted Office document delivered using a link shared via instant messaging or email. "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." "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," Microsoft explains. The security flaw, tracked as CVE-2022-21840, is a remote code execution (RCE) bug that attackers can exploit with no privileges on the targeted devices as part of low complexity attacks that require user interaction.
