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-2014-3343 in the wild and no public exploit code.\n\nAffected product: Cisco Ios Xr. 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-2014-3343/ (Markdown: https://insights.sbomify.com/CVE-2014-3343/index.md)","id":"CVE-2014-3343","markdown":"https://insights.sbomify.com/CVE-2014-3343/index.md","name":"CVE-2014-3343","record":{"aliases":["GHSA-r38f-6v34-qc3q"],"analysis":{"component_type":"network_device","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Cisco IOS XR","requires_auth":"none","summary":"Remote attackers can crash the DHCPv6 daemon in Cisco IOS XR by sending malformed packets, causing a denial of service.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"cisco","cpe":[{"product":"ios_xr","vendor":"cisco"}],"cvss":{"score":4.3,"severity":"medium","source":"nvd","vector":"AV:N/AC:M/Au:N/C:N/I:N/A:P","version":"2.0"},"cwes":[{"id":"CWE-20","name":"Improper Input Validation"}],"description":"Cisco IOS XR 5.1 allows remote attackers to cause a denial of service (DHCPv6 daemon crash) via a malformed DHCPv6 packet, aka Bug ID CSCuo59052.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Denial of service in n/a","id":"CVE-2014-3343","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"cisco:ios_xr","products":["cisco:ios_xr"],"type":"denial_of_service","year":"2014"},"n_packages":0,"n_references":6,"next":{"headline":"Cross-site scripting in n/a","id":"CVE-2014-3344"},"packages":[],"prev":{"headline":"Information disclosure in n/a","id":"CVE-2014-3342"},"products":["n/a"],"published":"2014-09-10","related":[{"cvss_score":8.8,"headline":"Cisco IOS XR Software Discovery Protocol Format String","id":"CVE-2020-3118","kev_date_added":"2021-11-03","published":"2020-02-05"},{"cvss_score":8.6,"headline":"Cisco IOS XR Software DVMRP Memory Exhaustion","id":"CVE-2020-3569","kev_date_added":"2021-11-03","published":"2020-09-23"},{"cvss_score":8.6,"headline":"Cisco IOS XR Software DVMRP Memory Exhaustion","id":"CVE-2020-3566","kev_date_added":"2021-11-03","published":"2020-08-29"},{"cvss_score":7.5,"headline":"Cisco IOS XR Border Gateway Protocol (BGP) Denial-of-Service","id":"CVE-2010-3035","kev_date_added":"2022-03-25","published":"2010-08-30"},{"cvss_score":6.5,"headline":"Cisco IOS XR Open Port","id":"CVE-2022-20821","kev_date_added":"2022-05-23","published":"2022-05-26"},{"cvss_score":5.9,"headline":"Cisco IOS XR Border Gateway Protocol (BGP) Denial-of-Service","id":"CVE-2009-2055","kev_date_added":"2022-03-25","published":"2009-08-19"},{"cvss_score":9.8,"headline":"Cisco IOS XR Software Security Hardening Release: September 2026","id":"CVE-2026-20274","kev_date_added":null,"published":"2026-09-02"}],"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":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-06","vendors":["n/a"]},"summary":"Remote attackers can crash the DHCPv6 daemon in Cisco IOS XR by sending malformed packets, causing a denial of service.","url":"https://insights.sbomify.com/CVE-2014-3343/"}
