CSRF needs no attacker credentials (PR:N) but requires an admin to visit a malicious page (UI:R); forged state-changing admin actions give I:H and possible A:H, while unreadable cross-origin responses justify C:N.

Nozomi Networks Labs identified a CWE-352: Cross-Site Request Forgery (CSRF) vulnerability in the LuCI administrative web interface of Advantech EKI-1242IEIMS in firmware version V1.06.01 that allows a remote unauthenticated attacker to perform unauthorized state-changing requests on behalf of a logged-in administrator, enabling unauthorized access to privileged management functions.
AnalysisAI
Cross-site request forgery in the LuCI administrative web interface of Advantech EKI-1242IEIMS running firmware V1.06.01 allows a remote, unauthenticated attacker to make an authenticated administrator's browser issue unauthorized state-changing requests, reaching privileged device management functions with high integrity and availability impact (vendor CVSS 4.0 base 8.6; independent 3.1 assessment AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:H/A:H). Exploitation is conditional and social-engineering dependent: the administrator must hold an active LuCI session and be lured into visiting attacker-controlled content, so the technique fails against logged-out or idle-session administrators and reliability is constrained by the required user interaction. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires an administrator to be actively authenticated to the LuCI administrative web interface of an Advantech EKI-1242IEIMS (firmware V1.06.01) AND to be lured into visiting attacker-controlled web content while that session is active (UI:A). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The vendor CVSS 4.0 score of 8.6 (AV:N/AC:L/AT:N/PR:N/UI:A/VC:H/VI:H/VA:H) reflects a network-reachable, low-complexity CSRF requiring victim interaction (UI:A). … 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 release specified in the Advantech security advisory for EKI-1242IEIMS (https://advcloudfiles.advantech.com/cms/5dafee28-ad53-4d07-a328-7896fcc24b6e/Security%20Advisory%20PDF%20File/SECURITY-ADVISORY----EKI-1242IEIMS-updated-20260904.pdf); the provided data does not state an exact patched version number, so the vendor advisory must be consulted for the applicable build, and operators of EKI-1242EIMS units appearing in the CPE data should confirm coverage with Advantech. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, inventory all Advantech EKI-1242IEIMS units and confirm which are running firmware V1.06.01, then restrict LuCI administrative access to a dedicated management VLAN or trusted jump hosts and require administrators to log out of LuCI when not actively administering the device. …
