Firmware Validation Logic Flaw in Supermicro's BMC on MBD-X12STW

CVE-2025-7937

What is CVE-2025-7937?

CVE-2025-7937 is a significant vulnerability identified in the firmware validation logic of Supermicro's Baseboard Management Controller (BMC) specifically on the MBD-X12STW motherboard. The BMC plays a crucial role in managing the system's hardware and performing tasks like remote management and monitoring, making it an integral component in server administration. This vulnerability permits an attacker to upload and replace the system firmware with a maliciously crafted image. If exploited, this flaw could critically undermine the integrity of the system, allowing unauthorized individuals to manipulate hardware settings, gain excessive control, and potentially disrupt operations.

Potential impact of CVE-2025-7937

1. Unauthorized Firmware Manipulation: Attackers could gain the capability to install rogue firmware, leading to unauthorized modifications in system operations, escalation of privileges, and control over hardware functionalities.

2. System Compromise and Data Breach: An exploited vulnerability can allow attackers to execute arbitrary code on the affected system, paving the way for data breaches and unauthorized access to sensitive information.

3. Operational Disruption: With compromised BMC functionality, operational processes could face interruptions due to malicious activities, negatively affecting service availability and organizational productivity.
