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-2021-38443 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-2021-38443/ (Markdown: https://insights.sbomify.com/CVE-2021-38443/index.md)","id":"CVE-2021-38443","markdown":"https://insights.sbomify.com/CVE-2021-38443/index.md","name":"CVE-2021-38443","record":{"aliases":["DEBIAN-CVE-2021-38443","GHSA-fq6w-j34v-phjr","UBUNTU-CVE-2021-38443"],"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":"Attackers can write arbitrary values in the XML parser due to improper handling of invalid structures, potentially leading to code execution.","user_interaction":"not_required","vuln_class":"other"},"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-228","name":"Improper Handling of Syntactically Invalid Structure"}],"description":"Eclipse CycloneDDS versions prior to 0.8.0 improperly handle invalid structures, 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 Improper Handling of Syntactically Invalid Structure","id":"CVE-2021-38443","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"other","year":"2021"},"n_packages":0,"n_references":2,"next":{"headline":"OCI OpenDDS Secure Improper Handling of Length Parameter Inconsistency","id":"CVE-2021-38445"},"packages":[],"prev":{"headline":"FATEK Automation WinProladder","id":"CVE-2021-38442"},"products":["CycloneDDS"],"published":"2022-05-05","related":[{"cvss_score":6.6,"headline":"Eclipse CycloneDDS Write-what-where Condition","id":"CVE-2021-38441","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":"Attackers can write arbitrary values in the XML parser due to improper handling of invalid structures, potentially leading to code execution.","url":"https://insights.sbomify.com/CVE-2021-38443/"}
