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-2021-20707 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-2021-20707/ (Markdown: https://insights.sbomify.com/CVE-2021-20707/index.md)","id":"CVE-2021-20707","markdown":"https://insights.sbomify.com/CVE-2021-20707/index.md","name":"CVE-2021-20707","record":{"aliases":["GHSA-3jw5-8hpm-44m2"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"NEC Cluster Software","requires_auth":"none","summary":"An attacker can read files uploaded via the network due to improper input validation in NEC CLUSTERPRO X and EXPRESSCLUSTER X Transaction Server.","user_interaction":"not_required","vuln_class":"path_traversal"},"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":7.5,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-20","name":"Improper Input Validation"}],"description":"Improper input validation 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 read files upload via 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":"Path traversal in CLUSTERPRO X","id":"CVE-2021-20707","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"path_traversal","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"Command injection in NEC Aterm devices","id":"CVE-2021-20708"},"packages":[],"prev":{"headline":"File upload in CLUSTERPRO X","id":"CVE-2021-20706"},"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-2021-20702","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":"An attacker can read files uploaded via the network due to improper input validation in NEC CLUSTERPRO X and EXPRESSCLUSTER X Transaction Server.","url":"https://insights.sbomify.com/CVE-2021-20707/"}
