35
FAUCET Score

CVE-2014-6357 is a critical use-after-free vulnerability affecting multiple Microsoft Office products, including Office 2010, 2013, and Office for Mac 2011, as well as Word Viewer and Office Web Apps. This flaw allows remote attackers to execute arbitrary code by enticing a user to open a specially crafted Office document. With a CVSS score of 9.3, it represents a high-severity threat due to its network-based attack vector, medium attack complexity, and complete compromise of confidentiality, integrity, and availability. Despite its high FAUCET Risk Score of 98/100 and elevated EPSS, there is currently no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage.
