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-2026-3823 in the wild and no public exploit code.\n\nAffected product: Atop Technologies EHG2408. 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-2026-3823/ (Markdown: https://insights.sbomify.com/CVE-2026-3823/index.md)","id":"CVE-2026-3823","markdown":"https://insights.sbomify.com/CVE-2026-3823/index.md","name":"CVE-2026-3823","record":{"aliases":["GHSA-xwwx-hh9w-5r7f"],"analysis":{"component_type":"network_device","fix_type":"no_fix_stated","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Industrial Ethernet Switch","requires_auth":"none","summary":"Unauthenticated remote attackers can execute arbitrary code on Atop Technologies EHG2408 series switches via a stack-based buffer overflow.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"twcert","cpe":[{"product":"atop_ehg2408-2sfp_firmware","vendor":"blackbeartechhive"},{"product":"atop_ehg2408_firmware","vendor":"blackbeartechhive"}],"cvss":{"score":9.3,"severity":"critical","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-787","name":"Out-of-bounds Write"},{"id":"CWE-121","name":"Stack-based Buffer Overflow"}],"description":"EHG2408 series switch developed by Atop Technologies has a Stack-based Buffer Overflow vulnerability, allowing unauthenticated remote attackers to control the program's execution flow and execute arbitrary code.","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":"Atop Technologies｜EHG2408 series switch - Stack-based Buffer Overflow","id":"CVE-2026-3823","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2026"},"n_packages":0,"n_references":2,"next":{"headline":"WellChoose｜IFTOP - Open redirect","id":"CVE-2026-3824"},"packages":[],"prev":{"headline":"Taipower｜Taipower APP(Android) - Improper Certificate Validation","id":"CVE-2026-3822"},"products":["EHG2408","EHG2408-2SFP"],"published":"2026-03-09","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"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":"total"},"state":"PUBLISHED","updated":"2026-07-07","vendors":["Atop Technologies"]},"summary":"Unauthenticated remote attackers can execute arbitrary code on Atop Technologies EHG2408 series switches via a stack-based buffer overflow.","url":"https://insights.sbomify.com/CVE-2026-3823/"}
