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 industrial gateways (firmware V1.06.01) lets a remote authenticated attacker with high privileges execute arbitrary OS commands as root. Exploitation requires a valid high-privilege session (CVSS 4.0 PR:H) and network reachability to the management interface, but then yields full device compromise (VC:H/VI:H/VA:H). …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires an authenticated session at high privilege (PR:H) on the web management interface of an Advantech EKI-1242IEIMS running firmware V1.06.01; the attacker then supplies crafted request parameters that are improperly neutralized and executed as OS commands running as root. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 base score of 8.6 (High) is driven by full compromise potential (VC:H/VI:H/VA:H) via network vector with low complexity, but is meaningfully gated by PR:H - the attacker must already hold high-privilege authenticated access to the web management interface before injecting OS commands that run as root. … 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 | Apply the fixed firmware version as detailed in 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); the exact patched release is not specified in available data, so consult the advisory for the specific version. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, inventory all Advantech EKI-1242IEIMS gateways and confirm which are running firmware V1.06.01, then restrict management-interface exposure by removing internet-facing access and limiting reachability to a hardened administrative VLAN or jump host; rotate administrative credentials and enforce unique, strong passwords with multifactor authentication where the interface supports it, and audit management logs for unexpected command activity. …
