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-2021-20702 in the wild and no public exploit code.\n\nAffected product: NEC Corporation CLUSTERPRO X. 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-2021-20702/ (Markdown: https://insights.sbomify.com/CVE-2021-20702/index.md)","id":"CVE-2021-20702","markdown":"https://insights.sbomify.com/CVE-2021-20702/index.md","name":"CVE-2021-20702","record":{"aliases":["GHSA-cp66-cfh8-4ff4"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Cluster management software","requires_auth":"none","summary":"A buffer overflow in NEC CLUSTERPRO X allows remote attackers to execute arbitrary code via network requests.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"NEC","cpe":[{"product":"clusterpro_x","vendor":"nec"},{"product":"clusterpro_x_singleserversafe","vendor":"nec"},{"product":"expresscluster_x","vendor":"nec"},{"product":"expresscluster_x_singleserversafe","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-120","name":"Buffer Copy without Checking Size of Input"}],"description":"Buffer overflow vulnerability in the Transaction Server CLUSTERPRO X 4.3 for Windows and earlier, EXPRESSCLUSTER X 4.3 for Windows and earlier, CLUSTERPRO X 4.3 SingleServerSafe for Windows and earlier, EXPRESSCLUSTER X 4.3 SingleServerSafe for Windows and earlier allows attacker to remote code execution via a network.","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":"Memory corruption in CLUSTERPRO X","id":"CVE-2021-20702","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"Memory corruption in CLUSTERPRO X","id":"CVE-2021-20703"},"packages":[],"prev":{"headline":"Memory corruption in CLUSTERPRO X","id":"CVE-2021-20701"},"products":["CLUSTERPRO X"],"published":"2021-11-02","related":[{"cvss_score":9.8,"headline":"Memory corruption in CLUSTERPRO X","id":"CVE-2021-20700","kev_date_added":null,"published":"2021-11-02"},{"cvss_score":9.8,"headline":"Memory corruption in CLUSTERPRO X","id":"CVE-2021-20701","kev_date_added":null,"published":"2021-11-02"},{"cvss_score":9.8,"headline":"Memory corruption in CLUSTERPRO X","id":"CVE-2021-20703","kev_date_added":null,"published":"2021-11-02"},{"cvss_score":9.8,"headline":"Memory corruption in CLUSTERPRO X","id":"CVE-2021-20704","kev_date_added":null,"published":"2021-11-02"},{"cvss_score":7.5,"headline":"File upload in CLUSTERPRO X","id":"CVE-2021-20705","kev_date_added":null,"published":"2021-11-02"},{"cvss_score":7.5,"headline":"File upload in CLUSTERPRO X","id":"CVE-2021-20706","kev_date_added":null,"published":"2021-11-02"}],"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":"2024-08-03","vendors":["NEC Corporation"]},"summary":"A buffer overflow in NEC CLUSTERPRO X allows remote attackers to execute arbitrary code via network requests.","url":"https://insights.sbomify.com/CVE-2021-20702/"}
