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
OS command injection in the web management interface of Advantech EKI-1242IEIMS and EKI-1242EIMS industrial devices running firmware V1.06.01 lets a remote attacker who already holds a valid authenticated session on the management UI execute arbitrary operating system commands with root privileges through crafted request parameters. The vulnerability (CWE-78), reported by Nozomi Networks Labs, is rated 8.6 under CVSS 4.0 (our independent assessment maps it to 8.8 under CVSS 3.1, AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H), and the high PR:H value means the attacker must first authenticate - typically at administrator level - before the injection is reachable. …

Vulnerability AssessmentAI
| Exploitation | Requires network reachability to the web management interface of an Advantech EKI-1242IEIMS (or EKI-1242EIMS) running firmware V1.06.01, AND a valid authenticated session on that interface (vendor rates this PR:H / administrator-level). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | This is a genuine but privilege-gated priority. … 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 and no vendor-released patch identifier is present in the provided references, so the first action is to retrieve the Advantech security advisory (https://advcloudfiles.advantech.com/cms/5dafee28-ad53-4d07-a328-7896fcc24b6e/Security%20Advisory%20PDF%20File/SECURITY-ADVISORY----EKI-1242IEIMS-updated-20260904.pdf) and apply the vendor-designated firmware update for the EKI-1242IEIMS and EKI-1242EIMS as soon as it is confirmed; also monitor the Nozomi Networks Labs advisory (https://www.nozominetworks.com/labs/vulnerability-advisories-cve-2026-73165) for any revision. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, inventory every Advantech EKI-1242IEIMS and EKI-1242EIMS running firmware V1.06.01, confirm whether its web management interface is reachable from any untrusted network (including IT, Wi-Fi, VPN, or vendor-support paths), and where possible restrict management access to a dedicated hardened admin VLAN or local console only; rotate all administrative credentials for these devices and enable logging of management-interface activity to a monitored collector. …
