An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2021-43933 in the wild and no public exploit code.\n\nAffected product: FANUC ROBOGUIDE. 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-2021-43933/ (Markdown: https://insights.sbomify.com/CVE-2021-43933/index.md)","id":"CVE-2021-43933","markdown":"https://insights.sbomify.com/CVE-2021-43933/index.md","name":"CVE-2021-43933","record":{"aliases":["GHSA-q4g6-4qpc-738h"],"analysis":{"component_type":"ics_ot","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"FANUC ROBOGUIDE","requires_auth":"none","summary":"Attackers can cause a denial-of-service condition in FANUC ROBOGUIDE by sending unimpeded network requests that exhaust heap memory resources.","user_interaction":"required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"icscert","cpe":[{"product":"roboguide","vendor":"fanuc"}],"cvss":{"score":6.1,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:C/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-400","name":"Uncontrolled Resource Consumption"}],"description":"The affected product is vulnerable to a network-based attack by threat actors sending unimpeded requests to the receiving server, which could cause a denial-of-service condition due to lack of heap memory resources.","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":"ICSA-22-109-03 FANUC ROBOGUIDE Simulation Platform","id":"CVE-2021-43933","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"Elcomplus SmartPtt Unrestricted Upload of File with Dangerous Type","id":"CVE-2021-43934"},"packages":[],"prev":{"headline":"Elcomplus SmartPtt Cross-site Scripting","id":"CVE-2021-43932"},"products":["ROBOGUIDE"],"published":"2022-04-20","related":[{"cvss_score":6.1,"headline":"ICSA-22-109-03 FANUC ROBOGUIDE Simulation Platform","id":"CVE-2021-43988","kev_date_added":null,"published":"2022-04-20"},{"cvss_score":6.1,"headline":"ICSA-22-109-03 FANUC ROBOGUIDE Simulation Platform","id":"CVE-2021-43990","kev_date_added":null,"published":"2022-04-20"},{"cvss_score":6,"headline":"ICSA-22-109-03 FANUC ROBOGUIDE Simulation Platform","id":"CVE-2021-38483","kev_date_added":null,"published":"2022-04-20"},{"cvss_score":6,"headline":"ICSA-22-109-03 FANUC ROBOGUIDE Simulation Platform","id":"CVE-2021-43986","kev_date_added":null,"published":"2022-04-20"}],"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":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2025-04-16","vendors":["FANUC"]},"summary":"Attackers can cause a denial-of-service condition in FANUC ROBOGUIDE by sending unimpeded network requests that exhaust heap memory resources.","url":"https://insights.sbomify.com/CVE-2021-43933/"}
