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 the Advantech EKI-1242IEIMS and EKI-1242EIMS industrial gateways (firmware V1.06.01) lets an attacker who already holds high-privilege administrative credentials send a crafted HTTP request whose unsanitized parameters are passed into an OS command executed as root, yielding full compromise of confidentiality, integrity, and availability of the device. The attack is remote and low-complexity with no user interaction required, but it is access-gated: the CVSS 4.0 vector carries PR:H, so exploitation presupposes valid admin access to the management UI - no public exploit code has been identified at time of analysis and there is no confirmed active exploitation (CISA KEV). …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires the attacker to already possess high-privilege (administrative) authenticated access to the web management interface of the Advantech EKI-1242IEIMS/EKI-1242EIMS gateway running firmware V1.06.01 (PR:H). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | This is a genuine but access-gated vulnerability. … 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 | Patch status is not confirmed from the supplied data - no fixed firmware version is given in the input - so the first step is to obtain the patched firmware release and its applicability from Advantech's advisory (https://advcloudfiles.advantech.com/cms/5dafee28-ad53-4d07-a328-7896fcc24b6e/Security%20Advisory%20PDF%20File/SECURITY-ADVISORY----EKI-1242IEIMS-updated-20260904.pdf) and Nozomi's advisory (https://www.nozominetworks.com/labs/vulnerability-advisories-cve-2026-73167), then upgrade both EKI-1242IEIMS and EKI-1242EIMS units currently on firmware V1.06.01 and rotate all administrative credentials afterward on the assumption they may have been exposed to root-level command execution. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, inventory all Advantech EKI-1242IEIMS and EKI-1242EIMS devices running firmware V1.06.01, confirm whether their web management interfaces are reachable from untrusted networks, immediately restrict management access to trusted OT/IT management segments via firewall ACLs or VPN, and replace any default or weak administrative credentials with strong unique passwords. …
