Threat & Defense at a Glance
Threat & Defense Details
Likely Mitigating ControlsAI
Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Requires verification of digital signatures using organization-approved certificates before installation, directly preventing improper verification of cryptographic signatures.
Component authenticity commonly depends on cryptographic signatures; the control enforces proper verification of those signatures.
PKI certificates under an approved policy require cryptographic signature verification on issuance and validation.
Requires cryptographic signatures on authoritative data and support for verifying the chain of trust.
Mandates verification of cryptographic signatures (e.g., DNSSEC RRSIG) on resolution responses, addressing missing or bypassed signature checks.
Integrity tools commonly rely on cryptographic signatures whose improper validation this weakness covers.
Authenticity validation commonly relies on cryptographic signature or certificate checks that this control enforces.
MITRE ATT&CK Enterprise TechniquesAI
Why these techniques?
CVE directly bypasses firmware signature validation (CWE-347) to permit arbitrary system firmware images, enabling T1542.001 System Firmware for persistence.
NVD Description
There is a vulnerability in the Supermicro BMC firmware validation logic at Supermicro MBD-X12STW-F . An attacker can update the system firmware with a specially crafted image.
Deeper analysisAI
CVE-2025-12006, published on 2026-01-16, is a vulnerability in the Supermicro BMC firmware validation logic on the Supermicro MBD-X12STW-F motherboard. It enables an attacker to update the system firmware using a specially crafted image. The issue carries a CVSS v3.1 base score of 7.2 (AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H) and maps to CWE-347.
The vulnerability can be exploited by an attacker with high privileges over the network, requiring low complexity and no user interaction. Successful exploitation allows high-impact compromise of confidentiality, integrity, and availability on the affected system, such as arbitrary firmware modification leading to persistent control.
