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-2018-3767 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- memjs (npm): affected all versions up to 1.2.0; no fix listed\n- memjs (npm): affected all versions up to 1.2.0; no fix listed\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-2018-3767/ (Markdown: https://insights.sbomify.com/CVE-2018-3767/index.md)","id":"CVE-2018-3767","markdown":"https://insights.sbomify.com/CVE-2018-3767/index.md","name":"CVE-2018-3767","record":{"aliases":["GHSA-cx8m-8xmx-q8v3"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Node.js memcached client","requires_auth":"none","summary":"An attacker can cause a denial of service and uninitialized memory usage in the memjs library by sending typed input.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"hackerone","cpe":[{"product":"memjs","vendor":"memcachier"}],"cvss":{"score":9.1,"severity":"critical","source":"nvd","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:H","version":"3.0"},"cwes":[{"id":"CWE-400","name":"Uncontrolled Resource Consumption"}],"description":"`memjs` versions \u003c= 1.1.0 allocates and stores buffers on typed input, resulting in DoS and uninitialized memory usage.","ecosystems":["npm"],"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 memjs","id":"CVE-2018-3767","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"npm","product":null,"products":[],"type":"denial_of_service","year":"2018"},"n_packages":2,"n_references":1,"next":{"headline":"grape subject to Cross-site Scripting","id":"CVE-2018-3769"},"packages":[{"ecosystem":"npm","fixed":[],"introduced":["0"],"last_affected":["1.2.0"],"package":"memjs","purl":null,"source":"GHSA-cx8m-8xmx-q8v3"},{"ecosystem":"npm","fixed":[],"introduced":["0"],"last_affected":["1.2.0"],"package":"memjs","purl":"pkg:npm/memjs","source":"GHSA-cx8m-8xmx-q8v3"}],"prev":{"headline":"Path Traversal in buttle","id":"CVE-2018-3766"},"products":["memjs"],"published":"2018-07-05","related":[],"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":"2024-08-05","vendors":["https://github.com/memcachier"]},"summary":"An attacker can cause a denial of service and uninitialized memory usage in the memjs library by sending typed input.","url":"https://insights.sbomify.com/CVE-2018-3767/"}
