CVE-2026-3820: CWE-78 Improper neutralization of special elements used in an OS command ('OS command injection') in SMCI AS-2115HS-TNR
There is a vulnerability in the Supermicro BMC SMTP service at Supermicro AS-2115HS-TNR. An attacker may obtain administrator privileges and inject specially crafted characters into the SMTP service configuration. This may cause the underlying system to execute unintended commands during process invocation. Potential impact includes denial-of-service attacks, arbitrary code execution, or permanent compromise of the controller.
AI Analysis
Technical Summary
This vulnerability involves improper neutralization of special elements used in OS commands (CWE-78) within the SMTP service of the Supermicro AS-2115HS-TNR Baseboard Management Controller (BMC). An attacker with administrative privileges can inject malicious input into the SMTP service configuration, which may be executed by the underlying system during process invocation. This can result in denial-of-service, arbitrary code execution, or full compromise of the BMC. The affected product versions are 01.08.01 and 01.06.04. No patch or official remediation level has been disclosed by the vendor as of the publication date.
Potential Impact
Successful exploitation allows an attacker with administrator privileges to execute arbitrary OS commands on the BMC, potentially causing denial-of-service, arbitrary code execution, or permanent compromise of the controller. This could disrupt device management and impact system availability and security.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict administrative access to the BMC SMTP service configuration to trusted personnel only and monitor for suspicious activity related to SMTP configuration changes.
