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-2018-19831 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-2018-19831/ (Markdown: https://insights.sbomify.com/CVE-2018-19831/index.md)","id":"CVE-2018-19831","markdown":"https://insights.sbomify.com/CVE-2018-19831/index.md","name":"CVE-2018-19831","record":{"aliases":["GHSA-g2j6-57h3-m248"],"analysis":{"component_type":"other","fix_type":"patch","impacts":["privilege_escalation","data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"Ethereum smart contract","requires_auth":"none","summary":"Attackers can change the owner of the Cryptbond Network smart contract due to missing identity checks in the ToOwner function.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"cryptbond_network","vendor":"cryptbond_network_project"}],"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:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-287","name":"Improper Authentication"}],"description":"The ToOwner() function of a smart contract implementation for Cryptbond Network (CBN), an tradable Ethereum ERC20 token, allows attackers to change the owner of the contract, because the function does not check the caller's identity.","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":"Missing authorization in n/a","id":"CVE-2018-19831","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"missing_authorization","year":"2018"},"n_packages":0,"n_references":1,"next":{"headline":"Missing authorization in n/a","id":"CVE-2018-19832"},"packages":[],"prev":{"headline":"Missing authorization in n/a","id":"CVE-2018-19830"},"products":["n/a"],"published":"2019-12-31","related":[],"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":"Attackers can change the owner of the Cryptbond Network smart contract due to missing identity checks in the ToOwner function.","url":"https://insights.sbomify.com/CVE-2018-19831/"}
