Multiple Chinese Threat Groups Exploiting CVE-2018-0798 Equation Editor Vulnerability Since Late 2018
released on 2019-07-04 @ 01:54:58 PM
During Anomali Threat Researcher’s tracking of the “Royal Road” Rich Text Format (RTF) weaponizer, commonly used by multiple Chinese threat actors to exploit CVE-2017-11882 and CVE-2018-0802, it was discovered that multiple Chinese threat groups updated their weaponizer to exploit the Microsoft Equation Editor (EE) vulnerability CVE-2018-0798 late 2018. We believe the groups moved to use CVE-2018-0798 instead of the other Microsoft Equation Editor Remote Code Execution (RCE) vulnerabilities because the former is more reliable as it works on all known versions of Equation Editor.
