CVE-2020-8713

Vulnerability

CVE-2020-8713 is an improper authentication vulnerability in the firmware of Intel Server Boards, Server Systems, and Compute Modules prior to version 1.59 [1]. The flaw resides in the authentication mechanism used by the management interface, allowing an attacker to bypass verification without valid credentials.

Exploitation

An unauthenticated attacker with adjacent network access (e.g., on the same subnet) can exploit this vulnerability by sending specially crafted packets to the vulnerable management interface. No user interaction or prior authentication is required. The attacker can then gain privileged access to the device's management functions.

Impact

Successful exploitation allows the attacker to escalate privileges within the management interface, potentially leading to full control of the affected server, including the ability to modify firmware, access sensitive data, or disrupt operations.

Mitigation

Intel has released firmware version 1.59 to address this vulnerability [1]. Users are advised to update to this version or later. No workarounds are available; the only mitigation is applying the firmware update.
