It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2020-3415 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-2020-3415/ (Markdown: https://insights.sbomify.com/CVE-2020-3415/index.md)","id":"CVE-2020-3415","markdown":"https://insights.sbomify.com/CVE-2020-3415/index.md","name":"CVE-2020-3415","record":{"aliases":["GHSA-f9q3-64mg-5r5q"],"analysis":{"component_type":"network_device","fix_type":"patch","impacts":["code_execution","denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":true,"product_category":"Cisco NX-OS","requires_auth":"none","summary":"An adjacent attacker can execute arbitrary code or cause a denial of service on Cisco NX-OS devices by sending crafted CDP packets when jumbo frames are enabled.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"cisco","cpe":[{"product":"nx-os","vendor":"cisco"}],"cvss":{"score":8.8,"severity":"high","source":"cna","vector":"CVSS:3.0/AV:A/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"}],"description":"A vulnerability in the Data Management Engine (DME) of Cisco NX-OS Software could allow an unauthenticated, adjacent attacker to execute arbitrary code with administrative privileges or cause a denial of service (DoS) condition on an affected device. The vulnerability is due to insufficient input validation. An attacker could exploit this vulnerability by sending a crafted Cisco Discovery Protocol packet to a Layer 2-adjacent affected device. A successful exploit could allow the attacker to execute arbitrary code with administrative privileges or cause the Cisco Discovery Protocol process to crash and restart multiple times, causing the affected device to reload and resulting in a DoS condition. Note: Cisco Discovery Protocol is a Layer 2 protocol. To exploit this vulnerability, an attacker must be in the same broadcast domain as the affected device (Layer 2 adjacent). Exploitation of this vulnerability also requires jumbo frames to be enabled on the interface that receives the crafted Cisco Discovery Protocol packets on the affected device.","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":"Cisco NX-OS Software Data Management Engine Remote Code Execution Vulnerability","id":"CVE-2020-3415","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"cisco:nx-os","products":["cisco:nx-os"],"type":"memory_corruption","year":"2020"},"n_packages":0,"n_references":1,"next":{"headline":"Cisco IOS XE Software for Cisco ASR 900 Series Route Switch Processor 3 Arbitrary Code Execution Vulnerabilities","id":"CVE-2020-3416"},"packages":[],"prev":{"headline":"Cisco IOS XE Software for Cisco 4461 Integrated Services Routers Denial of Service Vulnerability","id":"CVE-2020-3414"},"products":["Cisco NX-OS Software"],"published":"2020-08-27","related":[{"cvss_score":6,"headline":"Cisco NX-OS Command Injection","id":"CVE-2024-20399","kev_date_added":"2024-07-02","published":"2024-07-01"},{"cvss_score":9.8,"headline":"Cisco NX-OS Software Unauthenticated Arbitrary File Actions Vulnerability","id":"CVE-2021-1361","kev_date_added":null,"published":"2021-02-24"},{"cvss_score":9.8,"headline":"Memory corruption in Cisco NX-OS unknown","id":"CVE-2018-0301","kev_date_added":null,"published":"2018-06-20"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2016-1453","kev_date_added":null,"published":"2016-10-06"},{"cvss_score":9.8,"headline":"Hardcoded credentials in n/a","id":"CVE-2016-1341","kev_date_added":null,"published":"2016-02-24"},{"cvss_score":8.8,"headline":"Cisco NX-OS Software NX-API Command Injection Vulnerability","id":"CVE-2022-20650","kev_date_added":null,"published":"2022-02-23"}],"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":"no","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2024-11-13","vendors":["Cisco"]},"summary":"An adjacent attacker can execute arbitrary code or cause a denial of service on Cisco NX-OS devices by sending crafted CDP packets when jumbo frames are enabled.","url":"https://insights.sbomify.com/CVE-2020-3415/"}
