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-2021-38487 in the wild and no public exploit code.\n\nAffected product: RTI Connext Micro. 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-2021-38487/ (Markdown: https://insights.sbomify.com/CVE-2021-38487/index.md)","id":"CVE-2021-38487","markdown":"https://insights.sbomify.com/CVE-2021-38487/index.md","name":"CVE-2021-38487","record":{"aliases":["GHSA-vhvr-hgg7-6xqj"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service","data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"RTI Connext DDS","requires_auth":"none","summary":"Attackers can cause denial of service and information exposure in RTI Connext products by sending specially crafted packets.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"icscert","cpe":[{"product":"connext_dds_micro","vendor":"rti"},{"product":"connext_professional","vendor":"rti"},{"product":"connext_secure","vendor":"rti"}],"cvss":{"score":8.8,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-923","name":"Improper Restriction of Communication Channel to Intended Endpoints"},{"id":"CWE-406","name":"Insufficient Control of Network Message Volume (Network Amplification)"}],"description":"RTI Connext Professional versions 4.1 to 6.1.0, and Connext Micro versions 2.4 and later are vulnerable when an attacker sends a specially crafted packet to flood target devices with unwanted traffic.
