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-2018-16733 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- github.com/ethereum/go-ethereum (Go): affected all versions; fixed in 1.8.14\n- github.com/ethereum/go-ethereum (Go): affected all versions; fixed in 1.8.14\n- github.com/ethereum/go-ethereum (Go): affected all versions; fixed in 1.8.14\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-2018-16733/ (Markdown: https://insights.sbomify.com/CVE-2018-16733/index.md)","id":"CVE-2018-16733","markdown":"https://insights.sbomify.com/CVE-2018-16733/index.md","name":"CVE-2018-16733","record":{"aliases":["GHSA-qr2j-wrhx-4829","GO-2022-0871"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Ethereum client","requires_auth":"none","summary":"An attacker can cause a denial of service in Go Ethereum by providing invalid block ranges to the trace API due to missing validation.","user_interaction":"not_required","vuln_class":"business_logic"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"go_ethereum","vendor":"ethereum"}],"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:H/A:N","version":"3.0"},"cwes":[{"id":"CWE-20","name":"Improper Input Validation"}],"description":"In Go Ethereum (aka geth) before 1.8.14, TraceChain in eth/api_tracer.go does not verify that the end block is after the start block.","ecosystems":["Go"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Go Ethereum Improper Input Validation","id":"CVE-2018-16733","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Go","product":null,"products":[],"type":"business_logic","year":"2018"},"n_packages":3,"n_references":1,"next":{"headline":"Cross-site scripting in n/a","id":"CVE-2018-16736"},"packages":[{"ecosystem":"Go","fixed":["1.8.14"],"introduced":["0"],"last_affected":[],"package":"github.com/ethereum/go-ethereum","purl":null,"source":"GHSA-qr2j-wrhx-4829"},{"ecosystem":"Go","fixed":["1.8.14"],"introduced":["0"],"last_affected":[],"package":"github.com/ethereum/go-ethereum","purl":"pkg:golang/github.com/ethereum/go-ethereum","source":"GHSA-qr2j-wrhx-4829"},{"ecosystem":"Go","fixed":["1.8.14"],"introduced":["0"],"last_affected":[],"package":"github.com/ethereum/go-ethereum","purl":"pkg:golang/github.com/ethereum/go-ethereum","source":"GO-2022-0871"}],"prev":{"headline":"Cross-site request forgery in n/a","id":"CVE-2018-16732"},"products":["n/a"],"published":"2018-09-08","related":[{"cvss_score":8.7,"headline":"Go Ethereum affected by DoS via malicious p2p message","id":"CVE-2026-26314","kev_date_added":null,"published":"2026-02-19"},{"cvss_score":7.5,"headline":"go-ethereum vulnerable to denial of service via crafted GraphQL query","id":"CVE-2023-42319","kev_date_added":null,"published":"2023-10-18"},{"cvss_score":7.5,"headline":"Denial of service via malicious p2p message in go-ethereum","id":"CVE-2023-40591","kev_date_added":null,"published":"2023-09-06"},{"cvss_score":7.5,"headline":"Denial of service in go-ethereum","id":"CVE-2021-42219","kev_date_added":null,"published":"2022-03-16"},{"cvss_score":7.5,"headline":"Denial of Service in Go-Ethereum","id":"CVE-2022-23327","kev_date_added":null,"published":"2022-03-04"},{"cvss_score":7.5,"headline":"Denial of Service in Go-Ethereum","id":"CVE-2022-23328","kev_date_added":null,"published":"2022-03-04"},{"cvss_score":7.5,"headline":"Denial of service in n/a","id":"CVE-2018-20421","kev_date_added":null,"published":"2018-12-24"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"class":"attribution","licence":"CC BY 4.0","name":"Go Vulnerability Database","prefix":"GO"},{"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":"An attacker can cause a denial of service in Go Ethereum by providing invalid block ranges to the trace API due to missing validation.","url":"https://insights.sbomify.com/CVE-2018-16733/"}
