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-2020-3119 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-2020-3119/ (Markdown: https://insights.sbomify.com/CVE-2020-3119/index.md)","id":"CVE-2020-3119","markdown":"https://insights.sbomify.com/CVE-2020-3119/index.md","name":"CVE-2020-3119","record":{"aliases":["GHSA-wq2m-fgj4-27jc"],"analysis":{"component_type":"network_device","fix_type":"patch","impacts":["code_execution","privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Cisco NX-OS","requires_auth":"none","summary":"An adjacent attacker can execute arbitrary code with administrative privileges on Cisco NX-OS devices by sending a malicious CDP packet.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"cisco","cpe":[{"product":"nx-os","vendor":"cisco"},{"product":"ucs_manager","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 Cisco Discovery Protocol implementation for Cisco NX-OS Software could allow an unauthenticated, adjacent attacker to execute arbitrary code or cause a reload on an affected device. The vulnerability exists because the Cisco Discovery Protocol parser does not properly validate input for certain fields in a Cisco Discovery Protocol message. An attacker could exploit this vulnerability by sending a malicious Cisco Discovery Protocol packet to an affected device. An successful exploit could allow the attacker to cause a stack overflow, which could allow the attacker to execute arbitrary code with administrative privileges on an affected device. 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).","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 Cisco Discovery Protocol Remote Code Execution Vulnerability","id":"CVE-2020-3119","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":2,"next":{"headline":"Cisco FXOS, IOS XR, and NX-OS Software Cisco Discovery Protocol Denial of Service Vulnerability","id":"CVE-2020-3120"},"packages":[],"prev":{"headline":"Cisco IOS XR Software Discovery Protocol Format String","id":"CVE-2020-3118"},"products":["Cisco Unified Computing System (Managed)"],"published":"2020-02-05","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"},{"cvss_score":8.8,"headline":"Cisco NX-OS Software Data Management Engine Remote Code Execution Vulnerability","id":"CVE-2020-3415","kev_date_added":null,"published":"2020-08-27"}],"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":"2024-11-15","vendors":["Cisco"]},"summary":"An adjacent attacker can execute arbitrary code with administrative privileges on Cisco NX-OS devices by sending a malicious CDP packet.","url":"https://insights.sbomify.com/CVE-2020-3119/"}
