40
FAUCET Score

CVE-2007-3027 is a race condition vulnerability in Microsoft Internet Explorer versions 5.01, 6, and 7, affecting various Windows operating systems. This flaw allows remote attackers to execute arbitrary code by manipulating the installation of multiple language packs, leading to memory corruption. With a CVSS score of 9.3 and a FAUCET Risk Score of 97/100, this vulnerability is considered critical due to its network-based attack vector, medium attack complexity, and complete compromise of confidentiality, integrity, and availability. While no public exploit code (Metasploit, Nuclei, ExploitDB) is currently available and it is not listed in CISA's KEV catalog, its high EPSS score suggests a significant likelihood of exploitation. Community discussion and media coverage for this CVE are minimal.
