CVE-2026-73172: CWE-78 Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') in Advantech EKI-1242IEIMS
Nozomi Networks Labs identified a CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') vulnerability in the edgserver management service of Advantech EKI-1242EIMS in firmware version V1.06.01 that allows a remote unauthenticated attacker to execute arbitrary OS commands as root via crafted requests to TCP port 5058.
AI Analysis
Technical Summary
This vulnerability (CWE-78) exists in the edgserver management service of Advantech EKI-1242IEIMS devices running firmware version V1.06.01 and earlier. An attacker can send specially crafted requests to TCP port 5058 to execute arbitrary operating system commands with root privileges without authentication. The CVSS 4.0 base score is 9.3, reflecting a critical severity with network attack vector, no required privileges or user interaction, and high impact on confidentiality, integrity, and availability.
Potential Impact
Successful exploitation allows a remote unauthenticated attacker to execute arbitrary OS commands as root on the affected device, potentially leading to full system compromise, data loss, or disruption of device functionality.
Mitigation Recommendations
No official patch or remediation information is provided in the available data. Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, restrict network access to TCP port 5058 to trusted sources only to reduce exposure.
