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-2021-32951 in the wild and no public exploit code.\n\nAffected product: Advantech 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-2021-32951/ (Markdown: https://insights.sbomify.com/CVE-2021-32951/index.md)","id":"CVE-2021-32951","markdown":"https://insights.sbomify.com/CVE-2021-32951/index.md","name":"CVE-2021-32951","record":{"aliases":["GHSA-9rgm-96q6-gc9m"],"analysis":{"component_type":"ics_ot","fix_type":"upgrade","impacts":["data_read","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Advantech WebAccess/NMS","requires_auth":"none","summary":"Unauthorized users can bypass authentication to view monitored resources and device details in Advantech WebAccess/NMS.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"icscert","cpe":[{"product":"webaccess\\/nms","vendor":"advantech"}],"cvss":{"score":5.3,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-287","name":"Improper Authentication"}],"description":"WebAccess/NMS (Versions prior to v3.0.3_Build6299) has an improper authentication vulnerability, which may allow unauthorized users to view resources monitored and controlled by the WebAccess/NMS, as well as IP addresses and names of all the devices managed via WebAccess/NMS.","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":"Advantech WebAccess/NMS Improper Authentication","id":"CVE-2021-32951","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"auth_bypass","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"Memory corruption in Drawings SDK","id":"CVE-2021-32952"},"packages":[],"prev":{"headline":"Information disclosure in Drawings SDK","id":"CVE-2021-32950"},"products":["WebAccess/NMS"],"published":"2021-10-27","related":[{"cvss_score":9.8,"headline":"File upload in WebAccess/NMS","id":"CVE-2020-10621","kev_date_added":null,"published":"2020-04-09"},{"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":"2024-09-16","vendors":["Advantech"]},"summary":"Unauthorized users can bypass authentication to view monitored resources and device details in Advantech WebAccess/NMS.","url":"https://insights.sbomify.com/CVE-2021-32951/"}
