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-2018-0378 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-2018-0378/ (Markdown: https://insights.sbomify.com/CVE-2018-0378/index.md)","id":"CVE-2018-0378","markdown":"https://insights.sbomify.com/CVE-2018-0378/index.md","name":"CVE-2018-0378","record":{"aliases":["GHSA-cqfr-gw47-8rvr"],"analysis":{"component_type":"network_device","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":true,"product_category":"Cisco Nexus Switch","requires_auth":"none","summary":"Remote attackers can cause denial of service on Cisco Nexus switches by flooding Precision Time Protocol traffic, requiring PTP to be enabled.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"cisco","cpe":[{"product":"nx-os","vendor":"cisco"}],"cvss":{"score":8.6,"severity":"high","source":"cna","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:C/C:N/I:N/A:H","version":"3.0"},"cwes":[{"id":"CWE-20","name":"Improper Input Validation"}],"description":"A vulnerability in the Precision Time Protocol (PTP) feature of Cisco Nexus 5500, 5600, and 6000 Series Switches running Cisco NX-OS Software could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. The vulnerability is due to a lack of protection against PTP frame flood attacks. An attacker could exploit this vulnerability by sending large streams of malicious IPv4 or IPv6 PTP traffic to the affected device. A successful exploit could allow the attacker to cause a DoS condition, impacting the traffic passing through the 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":"Denial of service in Cisco NX-OS Software for Nexus 6000 Series","id":"CVE-2018-0378","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"cisco:nx-os","products":["cisco:nx-os"],"type":"denial_of_service","year":"2018"},"n_packages":0,"n_references":3,"next":{"headline":"Memory corruption in Cisco Webex Network Recording Players unknown","id":"CVE-2018-0379"},"packages":[],"prev":{"headline":"Missing authorization in Cisco Policy Suite unknown","id":"CVE-2018-0377"},"products":["Cisco NX-OS Software for Nexus 6000 Series"],"published":"2018-10-17","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":"yes","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2024-11-26","vendors":["Cisco"]},"summary":"Remote attackers can cause denial of service on Cisco Nexus switches by flooding Precision Time Protocol traffic, requiring PTP to be enabled.","url":"https://insights.sbomify.com/CVE-2018-0378/"}
