It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2024-20294 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-2024-20294/ (Markdown: https://insights.sbomify.com/CVE-2024-20294/index.md)","id":"CVE-2024-20294","markdown":"https://insights.sbomify.com/CVE-2024-20294/index.md","name":"CVE-2024-20294","record":{"aliases":["GHSA-jjfr-9fr6-hh6r"],"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 OS","requires_auth":"none","summary":"An adjacent attacker can cause a denial of service on Cisco FXOS and NX-OS devices by sending crafted LLDP packets, potentially crashing the service or reloading the device.","user_interaction":"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"},{"product":"unified_computing_system","vendor":"cisco"}],"cvss":{"score":6.6,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:A/AC:L/PR:N/UI:R/S:C/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-805","name":"Buffer Access with Incorrect Length Value"}],"description":"A vulnerability in the Link Layer Discovery Protocol (LLDP) feature of Cisco FXOS Software and Cisco NX-OS Software could allow an unauthenticated, adjacent attacker to cause a denial of service (DoS) condition on an affected device.\r\n\r This vulnerability is due to improper handling of specific fields in an LLDP frame. An attacker could exploit this vulnerability by sending a crafted LLDP packet to an interface of an affected device and having an authenticated user retrieve LLDP statistics from the affected device through CLI show commands or Simple Network Management Protocol (SNMP) requests. A successful exploit could allow the attacker to cause the LLDP service to crash and stop running on the affected device. In certain situations, the LLDP crash may result in a reload of the affected device.\r\n\r Note: LLDP is a Layer 2 link protocol. To exploit this vulnerability, an attacker would need to be directly connected to an interface of an affected device, either physically or logically (for example, through a Layer 2 Tunnel configured to transport the LLDP protocol).","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 Cisco Firepower Extensible Operating System (FXOS)","id":"CVE-2024-20294","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"cisco:firepower_extensible_operating_system","products":["cisco:firepower_extensible_operating_system","cisco:nx-os","cisco:unified_computing_system"],"type":"denial_of_service","year":"2024"},"n_packages":0,"n_references":1,"next":{"headline":"Command injection in Cisco Unified Computing System (Standalone)","id":"CVE-2024-20295"},"packages":[],"prev":{"headline":"Security feature bypass in Cisco Adaptive Security Appliance (ASA) Software","id":"CVE-2024-20293"},"products":["Cisco Firepower Extensible Operating System (FXOS)","Cisco NX-OS Software","Cisco NX-OS System Software in ACI Mode","Cisco Unified Computing System (Managed)"],"published":"2024-02-28","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":"Cisco FXOS and NX-OS Software Link Layer Discovery Protocol Denial of Service Vulnerability","id":"CVE-2018-0395","kev_date_added":null,"published":"2018-10-17"},{"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":"partial"},"state":"PUBLISHED","updated":"2024-08-01","vendors":["Cisco"]},"summary":"An adjacent attacker can cause a denial of service on Cisco FXOS and NX-OS devices by sending crafted LLDP packets, potentially crashing the service or reloading the device.","url":"https://insights.sbomify.com/CVE-2024-20294/"}
