CVE-2016-0189

CVE-2016-0189 is a high-severity (CVSS 7.5) vulnerability in Microsoft Internet Explorer. CISA added it to the Known Exploited Vulnerabilities catalog on March 28, 2022, which means exploitation in the wild has been confirmed; US federal agencies had to remediate it by April 18, 2022. CISA also lists it as known to be used in ransomware campaigns, so it should be prioritised accordingly. Microsoft has 390 vulnerabilities in the KEV catalog, 117 of them linked to ransomware.

The Microsoft (1) JScript 5.8 and (2) VBScript 5.7 and 5.8 engines, as used in Internet Explorer 9 through 11 and other products, allow remote attackers to execute arbitrary code or cause a denial of service (memory corruption) via a crafted web site, aka "Scripting Engine Memory Corruption Vulnerability," a different vulnerability than CVE-2016-0187.
