- →VBScript execution policy bypass via MSXML XSL files — monitor for VBScript execution originating from MSXML/XSL transformation contexts in Internet Explorer, even when the Internet Zone VBScript policy (registry key 140C=3) is enforced. ↗
- →Alert on IE processes spawning child processes or executing arbitrary code at medium-integrity level, which is the privilege level achieved by successful exploitation. ↗
- →Monitor for web-based delivery: users navigating to attacker-controlled sites hosting specially crafted HTML/XSL content designed to trigger VBScript execution through MSXML in IE 9, 10, or 11. ↗
- →Audit the registry key HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Internet Settings\Zones\3\140C; a value of 3 should disable VBScript in the Internet Zone, but this control is bypassed via MSXML XSL — verify patching status rather than relying solely on this policy. ↗
- ·The VBScript execution policy (registry key 140C=3) intended to disable VBScript in IE 11 for the Internet Zone does NOT cover VBScript embedded in MSXML XSL files, making the policy control insufficient as a standalone mitigation for this CVE. ↗
- ·This bypass was confirmed on Windows 10 Version 1803 with the latest patches applied at the time of disclosure, meaning fully-patched systems (pre-December 2018 patch) were still vulnerable. ↗

CVE-2018-8619 [HIGH] Internet Explorer Remote Code Execution Vulnerability
Internet Explorer Remote Code Execution Vulnerability
Description: A remote code execution vulnerability exists when the Internet Explorer VBScript execution policy does not properly restrict VBScript under specific conditions. An attacker who exploited the vulnerability could run arbitrary code with medium-integrity level privileges (the permissions of the current user).
In a web-based attack scenario, an attacker could host a website in an attempt to exploit this vulnerability. In addition, compromised websites and websites that accept or host user-provided content could contain specially crafted content that could exploit the vulnerability.
However, in all cases, an attacker would have no way to force users to view the attacker-controlled content. Instead, an attacker would have to con
