CVE-2023-40547 at MITRE

Description

A remote code execution vulnerability was found in Shim. The Shim boot support trusts attacker-controlled values when parsing an HTTP response. This flaw allows an attacker to craft a specific malicious HTTP request, leading to a completely controlled out-of-bounds write primitive and complete system compromise. This flaw is only exploitable during the early boot phase, an attacker needs to perform a Man-in-the-Middle or compromise the boot server to be able to exploit this vulnerability successfully.

Note from the SUSE Security Team

This can only be exploited IF the UEFI bios boots via HTTP from a remote server, and there is possibility for an attacker to pose as a malicious server. This is not a common boot scenario.
