This article provides detailed information about CVE-2023-28411, including its description, impact, technical details, and mitigation strategies.

Understanding CVE-2023-28411

CVE-2023-28411 is a vulnerability related to a double free issue in some Intel(R) Server Board BMC firmware before version 2.90. This vulnerability may allow a privileged user to enable information disclosure through local access.

What is CVE-2023-28411?

The CVE-2023-28411 vulnerability involves a double free scenario in the Intel(R) Server Board BMC firmware. This flaw can potentially be exploited by a privileged user to execute an information disclosure attack when accessing the system locally.

The Impact of CVE-2023-28411

The impact of CVE-2023-28411 is rated as MEDIUM severity according to the CVSS (Common Vulnerability Scoring System) version 3.1. The confidentiality impact is low, integrity impact is high, and availability impact is none. The vulnerability requires high privileges, user interaction is required, and the attack vector is local with low complexity.

Technical Details of CVE-2023-28411

The technical details of CVE-2023-28411 are as follows:

Vulnerability Description

The vulnerability is due to a double free issue in some versions of the Intel(R) Server Board BMC firmware. Exploiting this vulnerability could lead to unauthorized information disclosure by a privileged user with local access to the affected system.

Affected Systems and Versions

The affected system is the Intel(R) Server Board BMC firmware before version 2.90. Systems running versions prior to 2.90 are vulnerable to exploitation of the double free flaw.

Exploitation Mechanism

The exploitation of CVE-2023-28411 involves a privileged user with high privileges gaining local access to the system and leveraging the double free vulnerability in the Intel(R) Server Board BMC firmware.

Mitigation and Prevention

To protect systems from CVE-2023-28411, the following mitigation and prevention measures are recommended:

Immediate Steps to Take

Update the Intel(R) Server Board BMC firmware to version 2.90 or newer to address the double free vulnerability.
Restrict and monitor privileged user access to the affected systems to prevent unauthorized disclosure of information.

Long-Term Security Practices

Regularly monitor security advisories and updates from Intel regarding the Intel(R) Server Board BMC firmware to stay informed about potential vulnerabilities.
Implement strong access controls and authentication mechanisms to limit user privileges and reduce the risk of exploitation.

Patching and Updates
