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-2015-4323 in the wild and no public exploit code.\n\nAffected product: Cisco Nx-Os. 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-2015-4323/ (Markdown: https://insights.sbomify.com/CVE-2015-4323/index.md)","id":"CVE-2015-4323","markdown":"https://insights.sbomify.com/CVE-2015-4323/index.md","name":"CVE-2015-4323","record":{"aliases":["GHSA-f846-7hhm-3qxh"],"analysis":{"component_type":"network_device","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Cisco Nexus Switch","requires_auth":"none","summary":"Remote attackers can cause a denial of service on Cisco Nexus devices via crafted ARP packets due to a buffer overflow in MTU validation.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"cisco","cpe":[{"product":"mds_9000_nx-os","vendor":"cisco"},{"product":"nx-os","vendor":"cisco"}],"cvss":{"score":6.1,"severity":"medium","source":"nvd","vector":"AV:A/AC:L/Au:N/C:N/I:N/A:C","version":"2.0"},"cwes":[{"id":"CWE-119","name":"Improper Restriction of Operations within the Bounds of a Memory Buffer"}],"description":"Buffer overflow in Cisco NX-OS on Nexus 1000V devices for VMware vSphere 7.3(0)ZN(0.9); Nexus 3000 devices 6.0(2)U5(1.41), 7.0(3)I2(0.373), and 7.3(0)ZN(0.83); Nexus 4000 devices 4.1(2)E1(1b); Nexus 7000 devices 6.2(14)S1; Nexus 9000 devices 7.3(0)ZN(0.9); and MDS 9000 devices 6.2 (13) and 7.1(0)ZN(91.99) and MDS SAN-OS 7.1(0)ZN(91.99) allows remote attackers to cause a denial of service (device outage) via a crafted ARP packet, related to incorrect MTU validation, aka Bug IDs CSCuv71933, CSCuv61341, CSCuv61321, CSCuu78074, CSCut37060, CSCuv61266, CSCuv61351, CSCuv61358, and CSCuv61366.","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":"Memory corruption in n/a","id":"CVE-2015-4323","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"cisco:nx-os","products":["cisco:nx-os"],"type":"memory_corruption","year":"2015"},"n_packages":0,"n_references":3,"next":{"headline":"Memory corruption in n/a","id":"CVE-2015-4324"},"packages":[],"prev":{"headline":"Missing authorization in n/a","id":"CVE-2015-4322"},"products":["n/a"],"published":"2015-08-19","related":[{"cvss_score":6.5,"headline":"Denial of service in Cisco NX-OS Software Fibre Channel over Ethernet","id":"CVE-2017-6655","kev_date_added":null,"published":"2017-06-13"},{"cvss_score":5,"headline":"Denial of service in n/a","id":"CVE-2015-0775","kev_date_added":null,"published":"2015-06-12"},{"cvss_score":5,"headline":"Denial of service in n/a","id":"CVE-2012-1340","kev_date_added":null,"published":"2012-08-06"}],"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 cause a denial of service on Cisco Nexus devices via crafted ARP packets due to a buffer overflow in MTU validation.","url":"https://insights.sbomify.com/CVE-2015-4323/"}
