Descriptions

A security feature bypass vulnerability exists when Internet Explorer VBScript execution policy does not properly restrict VBScript under specific conditions, and to allow requests that should otherwise be ignored, aka 'Internet Explorer Security Feature Bypass Vulnerability'. This CVE ID is unique from CVE-2019-0761.

Se presenta una vulnerabilidad de omisión de la característica de seguridad cuando la política de ejecución de VBScript de Internet Explorer no restringe apropiadamente VBScript bajo condiciones específicas y permite peticiones que de otro modo deberían ser ignoradas, también conocidas como " Internet Explorer Security Feature Bypass Vulnerability”. Este ID de CVE es diferente de CVE-2019-0761.

MSHTML only checks for the CLSID associated with VBScript when blocking in the Internet Zone, but doesn't check other VBScript CLSIDs which allow a web page to bypass the security zone policy.
