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-2017-8338 in the wild and no public exploit code.\n\nAffected product: Mikrotik Routeros. 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-2017-8338/ (Markdown: https://insights.sbomify.com/CVE-2017-8338/index.md)","id":"CVE-2017-8338","markdown":"https://insights.sbomify.com/CVE-2017-8338/index.md","name":"CVE-2017-8338","record":{"aliases":["GHSA-h5g4-hpfp-3289"],"analysis":{"component_type":"network_device","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"MikroTik RouterOS","requires_auth":"none","summary":"Unauthenticated remote attackers can cause denial of service on MikroTik routers by flooding UDP port 500, disconnecting devices and clearing logs.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"routeros","vendor":"mikrotik"}],"cvss":{"score":7.5,"severity":"high","source":"nvd","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.0"},"cwes":[{"id":"CWE-400","name":"Uncontrolled Resource Consumption"}],"description":"A vulnerability in MikroTik Version 6.38.5 could allow an unauthenticated remote attacker to exhaust all available CPU via a flood of UDP packets on port 500 (used for L2TP over IPsec), preventing the affected router from accepting new connections; all devices will be disconnected from the router and all logs removed automatically.","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 n/a","id":"CVE-2017-8338","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"mikrotik:routeros","products":["mikrotik:routeros"],"type":"denial_of_service","year":"2017"},"n_packages":0,"n_references":4,"next":{"headline":"Denial of service in n/a","id":"CVE-2017-8339"},"packages":[],"prev":{"headline":"Cross-site request forgery in n/a","id":"CVE-2017-8337"},"products":["n/a"],"published":"2017-05-18","related":[{"cvss_score":9.8,"headline":"MikroTik RouterOS Stack-Based Buffer Overflow","id":"CVE-2018-7445","kev_date_added":"2022-09-08","published":"2018-03-19"},{"cvss_score":9.2,"headline":"MikroTik RouterOS Improper Neutralization of Argument Delimiters in a Command","id":"CVE-2026-86060","kev_date_added":"2026-09-10","published":"2026-09-05"},{"cvss_score":9.1,"headline":"MikroTik Router OS Directory Traversal","id":"CVE-2018-14847","kev_date_added":"2021-12-01","published":"2018-08-02"},{"cvss_score":8.8,"headline":"MikroTik RouterOS Missing Authentication for Critical Function","id":"CVE-2026-67277","kev_date_added":"2026-09-10","published":"2026-09-05"},{"cvss_score":6.9,"headline":"Mikrotik RouterOS Improper Enforcement of Behavioral Workflow","id":"CVE-2026-67279","kev_date_added":"2026-09-25","published":"2026-09-05"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2017-20149","kev_date_added":null,"published":"2022-10-15"},{"cvss_score":9.8,"headline":"Path traversal in n/a","id":"CVE-2022-34960","kev_date_added":null,"published":"2022-08-25"}],"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":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-05","vendors":["n/a"]},"summary":"Unauthenticated remote attackers can cause denial of service on MikroTik routers by flooding UDP port 500, disconnecting devices and clearing logs.","url":"https://insights.sbomify.com/CVE-2017-8338/"}
