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-2020-26800 in the wild and no public exploit code.\n\nAffected product: n/a. 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-2020-26800/ (Markdown: https://insights.sbomify.com/CVE-2020-26800/index.md)","id":"CVE-2020-26800","markdown":"https://insights.sbomify.com/CVE-2020-26800/index.md","name":"CVE-2020-26800","record":{"aliases":["GHSA-8pw5-pwp5-8mcx"],"analysis":{"component_type":"desktop_application","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":true,"product_category":"Ethereum client","requires_auth":"none","summary":"A stack overflow in the Aleth Ethereum client allows attackers to cause a denial of service via a crafted configuration file.","user_interaction":"required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"aleth","vendor":"ethereum"}],"cvss":{"score":5.5,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-787","name":"Out-of-bounds Write"}],"description":"A stack overflow vulnerability in Aleth Ethereum C++ client version \u003c= 1.8.0 using a specially crafted a config.json file may result in a denial of service.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":false,"headline":"Denial of service in n/a","id":"CVE-2020-26800","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2020"},"n_packages":0,"n_references":3,"next":{"headline":"Cross-site scripting in n/a","id":"CVE-2020-26801"},"packages":[],"prev":{"headline":"Cross-site scripting in n/a","id":"CVE-2020-26799"},"products":["n/a"],"published":"2021-01-11","related":[{"cvss_score":6.8,"headline":"Missing authorization in CPP-Ethereum","id":"CVE-2017-12116","kev_date_added":null,"published":"2018-01-19"}],"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":"2024-08-04","vendors":["n/a"]},"summary":"A stack overflow in the Aleth Ethereum client allows attackers to cause a denial of service via a crafted configuration file.","url":"https://insights.sbomify.com/CVE-2020-26800/"}
