Mitigations

Установка обновлений из доверенных источников. В связи со сложившейся обстановкой и введенными санкциями против Российской Федерации рекомендуется устанавливать обновления программного обеспечения только после оценки всех сопутствующих рисков. Компенсирующие меры: - использование механизма SBAT для блокирования возможности использования цифровой подписи компонентов; - использование средств межсетевого экранирования для ограничения возможности удалённого доступа; - использование виртуальных частных сетей для организации удаленного доступа (VPN).

CVE-2023-40547 (GCVE-0-2023-40547)

Vulnerability from cvelistv5 – Published: 2024-01-25 15:54 – Updated: 2026-06-26 09:43

Title

Shim: rce in http boot support may lead to secure boot bypass

Summary

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.
