CVE-2022-34302· NVD / CVE Program· CNA mitre

A flaw was found in New Horizon Datasys bootloaders before 2022-06-01.

Noroxi assessment

Priority: Monitor (action score 26/100)

  • Public proof-of-concept code exists (GitHub); there is no record of exploitation in the wild.
  • Probability of exploitation in the next 30 days: 1% (FIRST EPSS); higher than 65.2% of all records.
  • Someone with local access to the system can trigger it. Administrator privileges are required. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: fwupd (AlmaLinux:9) 1.8.10-2.el9.alma; fwupd-devel (AlmaLinux:9) 1.8.10-2.el9.alma; fwupd-plugin-flashrom (AlmaLinux:9) 1.8.10-2.el9.alma.
  • Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Low priority for now. Upgrade to fwupd (AlmaLinux:9) 1.8.10-2.el9.alma; fwupd-devel (AlmaLinux:9) 1.8.10-2.el9.alma; fwupd-plugin-flashrom (AlmaLinux:9) 1.8.10-2.el9.alma or later.

Primary sources: NVD · CVE.org · FIRST EPSS

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.

Patch and commit links

Commit, PR and diff links among the references. A starting point for patch-diffing and variant hunting; fixes, not exploits.

No commit or PR link among the references.

Credits

All researchers

Finders, reporters and analysts named in the CNA record. Click a name for that researcher’s other records.

No credits in the CNA record.

Variant candidates

Same product, same weakness class, within 18 months. If the patch missed the root cause, the sibling bug is here.

No nightly-computed relations.

Chain candidates

An authentication bypass and a privilege-requiring bug in the same product, published close together: combined they may become an unauthenticated path.
