CVE-2026-73165: 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 web management interface of Advantech EKI-1242IEIMS in firmware version V1.06.01 that allows a remote authenticated attacker to execute arbitrary OS commands as root via crafted request parameters.
AI Analysis
Technical Summary
This vulnerability involves improper neutralization of special elements used in OS commands (CWE-78) within the web management interface of Advantech EKI-1242IEIMS devices running firmware version V1.06.01 or earlier. An attacker with valid authentication can exploit this flaw by crafting specific request parameters to execute arbitrary commands on the underlying operating system with root privileges. This could lead to full system compromise. The vulnerability was identified by Nozomi Networks Labs and is publicly documented as CVE-2026-73165.
Potential Impact
Successful exploitation allows a remote authenticated attacker to execute arbitrary OS commands as root on the affected device, potentially leading to complete control over the system and compromise of device integrity and confidentiality.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. No official fix or patch links are provided in the available data. Until a patch is available, restrict access to the web management interface to trusted users and networks, and monitor for suspicious authenticated activity.
