A vulnerability was found in Microsoft Windows Host Compute (Operating System) (the affected version is unknown). It has been declared as critical. Affected by this vulnerability is an unknown code of the component Host Compute Service Shim. The manipulation with an unknown input leads to a input validation vulnerability. The CWE definition for the vulnerability is CWE-20. The product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly. As an impact it is known to affect confidentiality, integrity, and availability. The summary by CVE is:

A remote code execution vulnerability exists when the Windows Host Compute Service Shim (hcsshim) library fails to properly validate input while importing a container image, aka "Windows Host Compute Service Shim Remote Code Execution Vulnerability." This affects Windows Host Compute.

The bug was discovered 05/02/2018. The weakness was released 05/02/2018 by Michael Hanselmann as confirmed security update guide (Website). It is possible to read the advisory at portal.msrc.microsoft.com. This vulnerability is known as CVE-2018-8115 since 03/14/2018. The attack can be launched remotely.

The pricing for an exploit might be around USD $5k-$25k at the moment (estimation calculated on 03/08/2023). The advisory points out:

A remote code execution vulnerability exists when the Windows Host Compute Service Shim (hcsshim) library fails to properly validate input while importing a container image. To exploit the vulnerability, an attacker would place malicious code in a specially crafted container image which, if an authenticated administrator imported (pulled), could cause a container management service utilizing the Host Compute Service Shim library to execute malicious code on the Windows host.

Applying a patch is able to eliminate this problem. A possible mitigation has been published immediately after the disclosure of the vulnerability.
