An attacker needs administrator access to exploit it, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-73177 in the wild and no public exploit code.\n\nAffected product: Advantech EKI-1242EIMS. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-73177/ (Markdown: https://insights.sbomify.com/CVE-2026-73177/index.md)","id":"CVE-2026-73177","markdown":"https://insights.sbomify.com/CVE-2026-73177/index.md","name":"CVE-2026-73177","record":{"aliases":["GHSA-pxh8-mw2j-c73g"],"analysis":{"component_type":"ics_ot","fix_type":"patch","impacts":["code_execution","privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"Industrial Ethernet Switch","requires_auth":"high_privilege","summary":"An authenticated administrator can install unsigned firmware on Advantech EKI-1242EIMS devices, leading to persistent platform compromise.","user_interaction":"not_required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Nozomi","cpe":[],"cvss":{"score":8.6,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-345","name":"Insufficient Verification of Data Authenticity"}],"description":"Nozomi Networks Labs identified a CWE-345: Insufficient Verification of Data Authenticity vulnerability in the firmware upgrade mechanism of the Advantech EKI-1242EIMS in firmware version V1.06.01.
