CVE-2015-6038

41
FAUCET Score

CVE-2015-6038 is a critical memory corruption vulnerability affecting multiple versions of Microsoft Excel, Excel for Mac, Excel Viewer, Office Compatibility Pack, and Excel Services on SharePoint Server. This flaw allows remote attackers to execute arbitrary code on a vulnerable system simply by tricking a user into opening a specially crafted Office document. With a CVSS score of 9.3, it presents a high risk due to its network-based attack vector, medium attack complexity, and complete compromise of confidentiality, integrity, and availability. Despite its severity and high EPSS and FAUCET Risk Scores, there is no public exploit code available (Metasploit, Nuclei, ExploitDB), nor is it listed in CISA's KEV catalog, and it has received minimal community discussion or media coverage.
