CVE-2023-35861 is a critical shell-injection vulnerability found in the firmware of Supermicro motherboards, specifically affecting models such as H12DST-B prior to version 03.10.35. This vulnerability allows remote attackers to inject and execute arbitrary commands as root on the Baseboard Management Controller (BMC). With a CVSS score of 9.8, this vulnerability poses a significant risk to organizations relying on affected Supermicro products.
The risk to organizations includes potential unauthorized access, data leakage, and compromise of the integrity and availability of critical systems. Given the nature of the vulnerability, attackers could exploit it over the network with low complexity, requiring no privileges or user interaction. This situation underscores the urgency for defenders to address this vulnerability immediately.
As of now, there are no known public exploits or Proof of Concept (PoC) code available, but the critical severity level suggests that organizations should remain vigilant. The urgency for patching this vulnerability cannot be understated, as it could lead to severe consequences if left unaddressed.
Organizations using affected Supermicro motherboards should prioritize updating to the latest firmware version to mitigate this vulnerability effectively. The potential impact on business operations makes immediate action essential.
Vulnerability Details
The official description notes that a shell-injection vulnerability exists in email notifications for Supermicro motherboards, allowing attackers to execute arbitrary commands. The vulnerability is categorized under CWE-78, indicating it is related to OS command injection. The critical CVSS score of 9.8 reflects the high level of threat posed by this vulnerability, particularly in a networked environment.
Technical Analysis
The root cause of CVE-2023-35861 lies in the handling of email notifications on Supermicro motherboards. This flaw enables an attacker to inject malicious commands that are executed with root privileges on the BMC. The attack vector is network-based, with low complexity, and does not require any prior privileges or user interaction for exploitation.
The vulnerability impacts confidentiality, integrity, and availability, as an attacker could manipulate system configurations or access sensitive data. Given the critical nature of the systems managed by BMCs, this vulnerability presents a serious threat to organizational security.
Risk & Impact Analysis
The potential impact of this vulnerability is substantial, given that it allows for remote command execution at the root level. Organizations that fail to patch this vulnerability risk significant operational disruptions, data breaches, and reputational harm. The critical CVSS score indicates that this vulnerability should be prioritized in remediation efforts.
