2DescriptionCVE.org
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.
AnalysisAI
Authenticated OS command injection in the web management interface of Advantech EKI-1242IEIMS and EKI-1242EIMS industrial gateways (reported in firmware V1.06.01) allows an attacker holding high-privilege management credentials to run arbitrary operating-system commands as root through crafted request parameters. Exploitation requires network reachability to the device's management plane plus valid privileged authentication (CVSS PR:H), after which a single low-complexity, no-interaction request yields full confidentiality, integrity, and availability impact on the appliance (assessed CVSS 3.1 base 8.8; vendor-published CVSS 4.0 score 8.6). …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires the attacker to be authenticated to the Advantech EKI-1242IEIMS/EKI-1242EIMS web management interface with high privileges (CVSS PR:H) and to reach it over the network (AV:N); once authenticated, a single crafted request with malicious parameters triggers command execution as root with no user interaction (UI:N) and low complexity (AC:L). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | This is a genuine but authentication-gated risk. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | No exact fixed firmware version is confirmed in the available data, so the first action is to consult the Advantech security advisory (SECURITY-ADVISORY----EKI-1242IEIMS-updated-20260904.pdf) and the Nozomi Networks advisory for the vendor-designated remediation build, then upgrade both EKI-1242IEIMS and EKI-1242EIMS units to that firmware - treating the currently reported vulnerable release as V1.06.01. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, inventory every Advantech EKI-1242IEIMS and EKI-1242EIMS gateway and confirm whether it runs firmware V1.06.01; immediately restrict access to the web management interface to a dedicated administrative VLAN or trusted jump host, block direct internet exposure, rotate all high-privilege management credentials, and enable logging on the devices and perimeter firewalls. …
