It can only be exploited from the same machine or local network, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2018-0395 and fix it if it is affected.\n\nWhat it is: CVE-2018-0395 is a high-severity denial of service vulnerability in Cisco Firepower Extensible Operating System, published on 17 Oct 2018. 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-2018-0395 in the wild and no public exploit code.\n\nAffected product: Cisco Firepower Extensible Operating System. 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-2018-0395/ (Markdown: https://insights.sbomify.com/CVE-2018-0395/index.md)","id":"CVE-2018-0395","markdown":"https://insights.sbomify.com/CVE-2018-0395/index.md","name":"CVE-2018-0395","record":{"aliases":["GHSA-3wmx-fc2q-p8g5"],"analysis":{"component_type":"network_device","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Cisco network switch","requires_auth":"none","summary":"An unauthenticated adjacent attacker can cause a denial of service by sending a crafted LLDP packet to Cisco network devices, triggering an unexpected reload.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"cisco","cpe":[{"product":"firepower_extensible_operating_system","vendor":"cisco"},{"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-20","name":"Improper Input Validation"}],"description":"A vulnerability in the Link Layer Discovery Protocol (LLDP) implementation for Cisco FXOS Software and Cisco NX-OS Software could allow an unauthenticated, adjacent attacker to cause a denial of service (DoS) condition when the device unexpectedly reloads. The vulnerability is due to improper input validation of certain type, length, value (TLV) fields of the LLDP frame header. An attacker could exploit this vulnerability by sending a crafted LLDP packet to an interface on the targeted device. A successful exploit could allow the attacker to cause the switch to reload unexpectedly.","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 FXOS and NX-OS Software Link Layer Discovery Protocol Denial of Service Vulnerability","id":"CVE-2018-0395","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"cisco:firepower_extensible_operating_system","products":["cisco:firepower_extensible_operating_system","cisco:nx-os"],"type":"denial_of_service","year":"2018"},"n_packages":0,"n_references":3,"next":{"headline":"Cross-site scripting in Cisco Unified Communications Manager IM And Presence Service unknown","id":"CVE-2018-0396"},"packages":[],"prev":{"headline":"Code injection in Cisco Cloud Services Platform 2100 unknown","id":"CVE-2018-0394"},"products":["Cisco NX-OS Software","Firepower 4100 Series Next-Generation Firewalls"],"published":"2018-10-17","related":[{"cvss_score":9.8,"headline":"Information disclosure in Cisco FXOS and NX-OS unknown","id":"CVE-2018-0310","kev_date_added":null,"published":"2018-06-21"},{"cvss_score":9.8,"headline":"Command injection in n/a","id":"CVE-2015-6435","kev_date_added":null,"published":"2016-01-22"},{"cvss_score":8.8,"headline":"Memory corruption in Cisco NX-OS Software","id":"CVE-2021-1368","kev_date_added":null,"published":"2021-02-24"},{"cvss_score":8.8,"headline":"Cisco FXOS Software Firepower Chassis Manager Cross-Site Request Forgery Vulnerability","id":"CVE-2020-3456","kev_date_added":null,"published":"2020-10-21"},{"cvss_score":8.8,"headline":"Cisco FXOS and NX-OS Software Cisco Discovery Protocol Arbitrary Code Execution and Denial of Service Vulnerability","id":"CVE-2020-3172","kev_date_added":null,"published":"2020-02-26"},{"cvss_score":8.8,"headline":"Memory corruption in Cisco FXOS and NX-OS unknown","id":"CVE-2018-0303","kev_date_added":null,"published":"2018-06-21"}],"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":"2024-11-26","vendors":["Cisco"]},"summary":"An unauthenticated adjacent attacker can cause a denial of service by sending a crafted LLDP packet to Cisco network devices, triggering an unexpected reload.","url":"https://insights.sbomify.com/CVE-2018-0395/"}
