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-2020-6638 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- grin (crates.io): affected all versions; fixed in 3.0.0\n- grin (crates.io): affected all versions; fixed in 3.0.0\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-2020-6638/ (Markdown: https://insights.sbomify.com/CVE-2020-6638/index.md)","id":"CVE-2020-6638","markdown":"https://insights.sbomify.com/CVE-2020-6638/index.md","name":"CVE-2020-6638","record":{"aliases":["GHSA-7w6p-rwhg-7h3g"],"analysis":{"component_type":"other","fix_type":"upgrade","impacts":["other"],"network_reachable":"yes","non_default_config":false,"product_category":"Grin cryptocurrency node","requires_auth":"none","summary":"Insufficient validation in Grin allows attackers to potentially disrupt node operations or cause unexpected behavior.","user_interaction":"not_required","vuln_class":"other"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"grin","vendor":"grin"}],"cvss":{"score":7.5,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-20","name":"Improper Input Validation"}],"description":"Grin through 2.1.1 has Insufficient Validation.","ecosystems":["crates.io"],"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":"Grin Insufficient Validation","id":"CVE-2020-6638","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"crates.io","product":null,"products":[],"type":"other","year":"2020"},"n_packages":2,"n_references":2,"next":{"headline":"Cross-site scripting in Fortinet FortiAnalyzer","id":"CVE-2020-6640"},"packages":[{"ecosystem":"crates.io","fixed":["3.0.0"],"introduced":["0"],"last_affected":[],"package":"grin","purl":null,"source":"GHSA-7w6p-rwhg-7h3g"},{"ecosystem":"crates.io","fixed":["3.0.0"],"introduced":["0"],"last_affected":[],"package":"grin","purl":"pkg:cargo/grin","source":"GHSA-7w6p-rwhg-7h3g"}],"prev":{"headline":"SQL injection in n/a","id":"CVE-2020-6637"},"products":["n/a"],"published":"2020-01-21","related":[{"cvss_score":9.8,"headline":"Path traversal in n/a","id":"CVE-2019-9195","kev_date_added":null,"published":"2019-02-26"},{"cvss_score":7.5,"headline":"Grin insufficient data validation","id":"CVE-2020-15899","kev_date_added":null,"published":"2020-07-28"},{"cvss_score":5.3,"headline":"Grin allows attackers to adversely affect availability of data on a Mimblewimble blockchain","id":"CVE-2020-12439","kev_date_added":null,"published":"2020-05-05"}],"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":"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":"Insufficient validation in Grin allows attackers to potentially disrupt node operations or cause unexpected behavior.","url":"https://insights.sbomify.com/CVE-2020-6638/"}
