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-2021-21901 in the wild and no public exploit code.\n\nAffected product: Garrett Metal Detectors. 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-2021-21901/ (Markdown: https://insights.sbomify.com/CVE-2021-21901/index.md)","id":"CVE-2021-21901","markdown":"https://insights.sbomify.com/CVE-2021-21901/index.md","name":"CVE-2021-21901","record":{"aliases":["GHSA-6m5j-hmv8-95g6"],"analysis":{"component_type":"iot_embedded","fix_type":"no_fix_stated","impacts":["code_execution","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Metal detector module","requires_auth":"none","summary":"A stack-based buffer overflow in Garrett Metal Detectors' iC Module allows remote attackers to execute arbitrary code or cause denial of service via malicious packets.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"talos","cpe":[{"product":"ic_module_cma","vendor":"garrett"}],"cvss":{"score":9.8,"severity":"critical","source":"cna","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.0"},"cwes":[{"id":"CWE-787","name":"Out-of-bounds Write"},{"id":"CWE-120","name":"Buffer Copy without Checking Size of Input"}],"description":"A stack-based buffer overflow vulnerability exists in the CMA check_udp_crc function of Garrett Metal Detectors’ iC Module CMA Version 5.0.
