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-2021-1424 in the wild and no public exploit code.\n\nAffected product: Cisco ASR 5000 Series Software. 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-2021-1424/ (Markdown: https://insights.sbomify.com/CVE-2021-1424/index.md)","id":"CVE-2021-1424","markdown":"https://insights.sbomify.com/CVE-2021-1424/index.md","name":"CVE-2021-1424","record":{"aliases":["GHSA-7q9w-6xw2-qfxq"],"analysis":{"component_type":"network_device","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Cisco ASR 5000","requires_auth":"none","summary":"Remote attackers can cause a denial of service by sending malformed IKEv2 packets to Cisco ASR 5000 devices, requiring software updates.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"cisco","cpe":[],"cvss":{"score":5.3,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L/RL:X/RC:X/E:X","version":"3.1"},"cwes":[{"id":"CWE-119","name":"Improper Restriction of Operations within the Bounds of a Memory Buffer"}],"description":"A vulnerability in the ipsecmgr process of Cisco\u0026nbsp;ASR 5000 Series Software (StarOS) could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition.\r\nThis vulnerability is due to insufficient validation of incoming Internet Key Exchange Version 2 (IKEv2) packets.
