CVSS: 7.5EPSS: 0%CPEs: 19EXPL: 0CVE-2022-34302 – shim: 3rd party shim allow secure boot bypass
https://notcve.org/view.php?id=CVE-2022-34302
A flaw was found in New Horizon Datasys bootloaders before 2022-06-01. An attacker may use this bootloader to bypass or tamper with Secure Boot protections. In order to load and execute arbitrary code in the pre-boot stage, an attacker simply needs to replace the existing signed bootloader currently in use with this bootloader. Access to the EFI System Partition is required for booting using external media. Se ha encontrado un fallo en los cargadores de arranque de New Horizon Datasys versiones anteriores a 01-06-2022. • https://edk2-docs.gitbook.io/understanding-the-uefi-secure-boot-chain/secure_boot_chain_in_uefi/uefi_secure_boot https://www.intel.com/content/www/us/en/security-center/advisory/intel-sa-01001.html https://www.kb.cert.org/vuls/id/309662 https://access.redhat.com/security/cve/CVE-2022-34302 https://bugzilla.redhat.com/show_bug.cgi?id=2120687 • CWE-494: Download of Code Without Integrity Check •
