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-2020-5684 in the wild and no public exploit code.\n\nAffected product: Management software for NEC Storage disk array system. 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-2020-5684/ (Markdown: https://insights.sbomify.com/CVE-2020-5684/index.md)","id":"CVE-2020-5684","markdown":"https://insights.sbomify.com/CVE-2020-5684/index.md","name":"CVE-2020-5684","record":{"aliases":["GHSA-87vv-9cj6-q2hc"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["data_read","data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"NEC Storage Manager","requires_auth":"none","summary":"Man-in-the-middle attackers can eavesdrop on or alter encrypted communications due to improper certificate verification in NEC Storage Manager clients.","user_interaction":"not_required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"jpcert","cpe":[{"product":"ism_server","vendor":"nec"}],"cvss":{"score":4.8,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-295","name":"Improper Certificate Validation"}],"description":"iSM client versions from V5.1 prior to V12.1 running on NEC Storage Manager or NEC Storage Manager Express does not verify a server certificate properly, which allows a man-in-the-middle attacker to eavesdrop on an encrypted communication or alter the communication via a crafted certificate.","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":"Security feature bypass in Management software for NEC Storage disk array system","id":"CVE-2020-5684","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"security_feature_bypass","year":"2020"},"n_packages":0,"n_references":2,"next":{"headline":"Command injection in UNIVERGE SV9500/SV8500 series","id":"CVE-2020-5685"},"packages":[],"prev":{"headline":"Path traversal in GROWI","id":"CVE-2020-5683"},"products":["Management software for NEC Storage disk array system"],"published":"2020-12-24","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":"Man-in-the-middle attackers can eavesdrop on or alter encrypted communications due to improper certificate verification in NEC Storage Manager clients.","url":"https://insights.sbomify.com/CVE-2020-5684/"}
