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-2020-5633 in the wild and no public exploit code.\n\nAffected product: Multiple NEC products where Baseboard Management Controller (BMC) firmware Rev1.09 and earlier is applied. 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-2020-5633/ (Markdown: https://insights.sbomify.com/CVE-2020-5633/index.md)","id":"CVE-2020-5633","markdown":"https://insights.sbomify.com/CVE-2020-5633/index.md","name":"CVE-2020-5633","record":{"aliases":["GHSA-g89v-h54q-6rcc"],"analysis":{"component_type":"hardware_firmware","fix_type":"upgrade","impacts":["security_bypass","data_read","data_modify","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"NEC server BMC firmware","requires_auth":"none","summary":"Remote attackers can bypass authentication on NEC server BMC firmware to read, modify settings, or disrupt operations.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"jpcert","cpe":[{"product":"baseboard_management_controller","vendor":"nec"}],"cvss":{"score":9.8,"severity":"critical","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-287","name":"Improper Authentication"}],"description":"Multiple NEC products (Express5800/T110j, Express5800/T110j-S, Express5800/T110j (2nd-Gen), Express5800/T110j-S (2nd-Gen), iStorage NS100Ti, and Express5800/GT110j) where Baseboard Management Controller (BMC) firmware Rev1.09 and earlier is applied allows remote attackers to bypass authentication and then obtain/modify BMC setting information, obtain monitoring information, or reboot/shut down the vulnerable product via unspecified vectors.","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":"Auth bypass in Multiple NEC products where Baseboard Management Controller (BMC) firmware Rev1.09 and earlier is applied","id":"CVE-2020-5633","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"auth_bypass","year":"2020"},"n_packages":0,"n_references":3,"next":{"headline":"Command injection in ELECOM LAN routers","id":"CVE-2020-5634"},"packages":[],"prev":{"headline":"Privilege escalation in InfoCage SiteShell series","id":"CVE-2020-5632"},"products":["Multiple NEC products where Baseboard Management Controller (BMC) firmware Rev1.09 and earlier is applied"],"published":"2021-01-13","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":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-04","vendors":["NEC Corporation"]},"summary":"Remote attackers can bypass authentication on NEC server BMC firmware to read, modify settings, or disrupt operations.","url":"https://insights.sbomify.com/CVE-2020-5633/"}
