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-2020-10621 in the wild and no public exploit code.\n\nAffected product: WebAccess/NMS. 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-2020-10621/ (Markdown: https://insights.sbomify.com/CVE-2020-10621/index.md)","id":"CVE-2020-10621","markdown":"https://insights.sbomify.com/CVE-2020-10621/index.md","name":"CVE-2020-10621","record":{"aliases":["GHSA-29v5-v73g-x3cp"],"analysis":{"component_type":"ics_ot","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"WebAccess/NMS","requires_auth":"none","summary":"Attackers can upload and execute arbitrary files on WebAccess/NMS, leading to remote code execution.","user_interaction":"not_required","vuln_class":"file_upload"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"icscert","cpe":[{"product":"webaccess\\/nms","vendor":"advantech"}],"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-434","name":"Unrestricted Upload of File with Dangerous Type"}],"description":"Multiple issues exist that allow files to be uploaded and executed on the WebAccess/NMS (versions prior to 3.0.2).","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":"File upload in WebAccess/NMS","id":"CVE-2020-10621","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"file_upload","year":"2020"},"n_packages":0,"n_references":1,"next":{"headline":"File upload in LCDS LAquis SCADA Versions 4.3.1 and prior","id":"CVE-2020-10622"},"packages":[],"prev":{"headline":"Missing authorization in Opto 22 SoftPAC Project","id":"CVE-2020-10620"},"products":["WebAccess/NMS"],"published":"2020-04-09","related":[{"cvss_score":9.8,"headline":"Auth bypass in WebAccess/NMS","id":"CVE-2020-10625","kev_date_added":null,"published":"2020-04-09"},{"cvss_score":9.8,"headline":"Path traversal in WebAccess/NMS","id":"CVE-2020-10631","kev_date_added":null,"published":"2020-04-09"},{"cvss_score":9.1,"headline":"Path traversal in WebAccess/NMS","id":"CVE-2020-10619","kev_date_added":null,"published":"2020-04-09"},{"cvss_score":8.8,"headline":"Command injection in WebAccess/NMS","id":"CVE-2020-10603","kev_date_added":null,"published":"2020-04-09"},{"cvss_score":7.5,"headline":"SQL injection in WebAccess/NMS","id":"CVE-2020-10617","kev_date_added":null,"published":"2020-04-09"},{"cvss_score":7.5,"headline":"XML external entity in WebAccess/NMS","id":"CVE-2020-10629","kev_date_added":null,"published":"2020-04-09"}],"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":["n/a"]},"summary":"Attackers can upload and execute arbitrary files on WebAccess/NMS, leading to remote code execution.","url":"https://insights.sbomify.com/CVE-2020-10621/"}
