An attacker can exploit it over the internet without logging in, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2026-73173 and fix it if it is affected.\n\nWhat it is: CVE-2026-73173 is a high-severity missing authorization vulnerability in Advantech EKI-1242EIMS, published on 16 Sep 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-73173 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-2026-73173/ (Markdown: https://insights.sbomify.com/CVE-2026-73173/index.md)","id":"CVE-2026-73173","markdown":"https://insights.sbomify.com/CVE-2026-73173/index.md","name":"CVE-2026-73173","record":{"aliases":["GHSA-r838-p3xg-9mfp"],"analysis":{"component_type":"network_device","fix_type":"patch","impacts":["privilege_escalation","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Industrial Ethernet Switch","requires_auth":"none","summary":"Remote unauthenticated attackers can invoke critical management functions like reboot and firmware upgrade on Advantech EKI-1242EIMS devices via TCP port 5058.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Nozomi","cpe":[],"cvss":{"score":8.8,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:H/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-306","name":"Missing Authentication for Critical Functionality"}],"description":"Nozomi Networks Labs identified a CWE-306: Missing Authentication for Critical Function vulnerability in the edgserver management protocol of Advantech EKI-1242EIMS in firmware version V1.06.01 that allows a remote unauthenticated attacker to invoke critical device-management functions, including network reconfiguration, reboot, reset, and firmware upgrade, by sending crafted requests to TCP port 5058.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Missing authorization in EKI-1242EIMS","id":"CVE-2026-73173","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"missing_authorization","year":"2026"},"n_packages":0,"n_references":2,"next":{"headline":"Information disclosure in EKI-1242EIMS","id":"CVE-2026-73174"},"packages":[],"prev":{"headline":"Command injection in EKI-1242EIMS","id":"CVE-2026-73172"},"products":["EKI-1242EIMS","EKI-1242IEIMS"],"published":"2026-09-16","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-09-17","vendors":["Advantech"]},"summary":"Remote unauthenticated attackers can invoke critical management functions like reboot and firmware upgrade on Advantech EKI-1242EIMS devices via TCP port 5058.","url":"https://insights.sbomify.com/CVE-2026-73173/"}
