#Security Vulnerability

**What kind of security feature could be bypassed by successfully exploiting this vulnerability?** A hypervisor-protected code integrity (HVCI) security feature bypass vulnerability could exist when Windows incorrectly allows certain kernel-mode pages to be marked as Read, Write, Execute (RWX) even with HVCI enabled. To exploit this vulnerability an attacker could run a specially crafted script at administrator level that exploits a signed driver to bypass code integrity protections in Windows.

**According to the CVSS metric, the attack complexity is high (AC:H). What does that mean for this vulnerability?** Successful exploitation of this vulnerability requires an attacker to prepare the target environment to improve exploit reliability.

**According to the CVSS metric, a successful exploitation could lead to a scope change (S:C). What does this mean for this vulnerability?** The vulnerability is in the web server, but the malicious scripts execute in the victim’s browser on their machine.

**How would an attacker exploit this vulnerability?** This vulnerability would require an authenticated attacker on a guest VM to send specially crafted file operation requests on the VM to hardware resources on the VM which could result in remote code execution on the host server.

**According to the CVSS metric, Attack Vector is Local (AV:L). What does that mean for this vulnerability?** An attacker would have to have local presence on the device through malware or a malicious application to be able to exploit this vulnerability.

**What privileges could be gained by an attacker who successfully exploited this vulnerability?** Successful exploitation of this vulnerability will locally elevate the attacker's privileges to communicate as Root with OMI server.

**How could an attacker exploit this vulnerability?** A remote unauthenticated attacker could access the OMI instance from the Internet and send specially crafted requests to trigger a use-after-free vulnerability.

**How could an attacker exploit the vulnerability?** An attacker could use the unsanitized parameter into a SQL query to trigger SQL Injection.

**What kind of security feature could be bypassed by successfully exploiting this vulnerability?** The authentication feature could be bypassed as this vulnerability allows impersonation.

**According to the CVSS metric, user interaction is required (UI:R). What interaction would the user have to do?** Exploitation of the vulnerability requires a user to modify a custom compliance script on the device after it is written to temporary storage and before execution of the script finishes.
