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-2021-38445 in the wild and no public exploit code.\n\nAffected product: OCI OpenDDS. 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-2021-38445/ (Markdown: https://insights.sbomify.com/CVE-2021-38445/index.md)","id":"CVE-2021-38445","markdown":"https://insights.sbomify.com/CVE-2021-38445/index.md","name":"CVE-2021-38445","record":{"aliases":["GHSA-3xm3-79jv-66p7"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"OpenDDS library","requires_auth":"none","summary":"An attacker can remotely execute arbitrary code due to improper handling of length parameters in the OpenDDS library.","user_interaction":"not_required","vuln_class":"integer_overflow"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"icscert","cpe":[{"product":"opendds","vendor":"objectcomputing"}],"cvss":{"score":7,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:L/A:H","version":"3.1"},"cwes":[{"id":"CWE-130","name":"Improper Handling of Length Parameter Inconsistency"}],"description":"OCI OpenDDS versions prior to 3.18.1 do not handle a length parameter consistent with the actual length of the associated data, which may allow an attacker to remotely execute arbitrary code.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":false,"headline":"OCI OpenDDS Secure Improper Handling of Length Parameter Inconsistency","id":"CVE-2021-38445","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"integer_overflow","year":"2021"},"n_packages":0,"n_references":2,"next":{"headline":"OCI OpenDDS Secure Amplification","id":"CVE-2021-38447"},"packages":[],"prev":{"headline":"Eclipse CycloneDDS Improper Handling of Syntactically Invalid Structure","id":"CVE-2021-38443"},"products":["OpenDDS"],"published":"2022-05-05","related":[{"cvss_score":8.6,"headline":"OCI OpenDDS Secure Amplification","id":"CVE-2021-38447","kev_date_added":null,"published":"2022-05-05"},{"cvss_score":7.5,"headline":"Integer overflow in n/a","id":"CVE-2025-67111","kev_date_added":null,"published":"2025-12-23"},{"cvss_score":7.5,"headline":"Denial of service in n/a","id":"CVE-2023-52427","kev_date_added":null,"published":"2024-02-11"},{"cvss_score":7.5,"headline":"Malformed PID_PROPERTY_LIST parameter in DATA submessage remotely crashes OpenDDS","id":"CVE-2023-37915","kev_date_added":null,"published":"2023-07-21"},{"cvss_score":6.6,"headline":"OCI OpenDDS Secure Network Amplification","id":"CVE-2021-38429","kev_date_added":null,"published":"2022-05-05"},{"cvss_score":5.3,"headline":"Specially crafted RTPS message may cause an OpenDDS application to crash","id":"CVE-2023-23932","kev_date_added":null,"published":"2023-02-03"}],"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":["OCI"]},"summary":"An attacker can remotely execute arbitrary code due to improper handling of length parameters in the OpenDDS library.","url":"https://insights.sbomify.com/CVE-2021-38445/"}
