CVE-2017-11822

CVE-2017-11822 is a memory corruption vulnerability in Internet Explorer across various Microsoft Windows versions, including Windows 7, 8.1, 10, and Server editions. This flaw allows an unauthenticated, remote attacker to execute arbitrary code in the context of the current user if they are tricked into visiting a malicious website. With a CVSS score of 7.5 (High), exploitation is complex but can lead to full compromise of confidentiality, integrity, and availability. While not listed in CISA's KEV catalog, its EPSS score indicates a higher-than-average probability of exploitation, and it received media coverage as part of a larger patch Tuesday. No public exploit code (Metasploit, Nuclei, ExploitDB) is currently available, and community discussion is limited.
