It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2021-38441 in the wild and no public exploit code.\n\nAffected product: Eclipse CycloneDDS. 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-2021-38441/ (Markdown: https://insights.sbomify.com/CVE-2021-38441/index.md)","id":"CVE-2021-38441","markdown":"https://insights.sbomify.com/CVE-2021-38441/index.md","name":"CVE-2021-38441","record":{"aliases":["DEBIAN-CVE-2021-38441","GHSA-9v3v-pqhw-3fhr","UBUNTU-CVE-2021-38441"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"DDS middleware library","requires_auth":"low_privilege","summary":"An attacker can exploit a write-what-where condition in the XML parser to write arbitrary values, potentially leading to code execution.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"icscert","cpe":[{"product":"cyclonedds","vendor":"eclipse"}],"cvss":{"score":6.6,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:H","version":"3.1"},"cwes":[{"id":"CWE-123","name":"Write-what-where Condition"}],"description":"Eclipse CycloneDDS versions prior to 0.8.0 are vulnerable to a write-what-where condition, which may allow an attacker to write arbitrary values in the XML parser.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Eclipse CycloneDDS Write-what-where Condition","id":"CVE-2021-38441","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2021"},"n_packages":0,"n_references":2,"next":{"headline":"FATEK Automation WinProladder","id":"CVE-2021-38442"},"packages":[],"prev":{"headline":"FATEK Automation WinProladder","id":"CVE-2021-38440"},"products":["CycloneDDS"],"published":"2022-05-05","related":[{"cvss_score":6.6,"headline":"Eclipse CycloneDDS Improper Handling of Syntactically Invalid Structure","id":"CVE-2021-38443","kev_date_added":null,"published":"2022-05-05"}],"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":["Eclipse"]},"summary":"An attacker can exploit a write-what-where condition in the XML parser to write arbitrary values, potentially leading to code execution.","url":"https://insights.sbomify.com/CVE-2021-38441/"}
