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-2018-3737 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- sshpk (npm): affected all versions; fixed in 1.13.2\n- sshpk (npm): affected all versions; fixed in 1.13.2\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-2018-3737/ (Markdown: https://insights.sbomify.com/CVE-2018-3737/index.md)","id":"CVE-2018-3737","markdown":"https://insights.sbomify.com/CVE-2018-3737/index.md","name":"CVE-2018-3737","record":{"aliases":["DEBIAN-CVE-2018-3737","GHSA-2m39-62fm-q8r3","UBUNTU-CVE-2018-3737"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Node.js SSH key library","requires_auth":"none","summary":"Attackers can cause denial of service in applications using sshpk by providing crafted invalid public keys that trigger excessive CPU usage.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"hackerone","cpe":[{"product":"sshpk","vendor":"joyent"}],"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-185","name":"Incorrect Regular Expression"},{"id":"CWE-770","name":"Allocation of Resources Without Limits or Throttling"}],"description":"sshpk is vulnerable to ReDoS when parsing crafted invalid public keys.","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":true,"headline":"Regular Expression Denial of Service in sshpk","id":"CVE-2018-3737","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":"Denial of Service in protobufjs","id":"CVE-2018-3738"},"packages":[{"ecosystem":"npm","fixed":["1.13.2"],"introduced":["0"],"last_affected":[],"package":"sshpk","purl":null,"source":"GHSA-2m39-62fm-q8r3"},{"ecosystem":"npm","fixed":["1.13.2"],"introduced":["0"],"last_affected":[],"package":"sshpk","purl":"pkg:npm/sshpk","source":"GHSA-2m39-62fm-q8r3"}],"prev":{"headline":"bracket-template vulnerable to reflected XSS","id":"CVE-2018-3735"},"products":["sshpk node module"],"published":"2018-06-07","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":"2024-09-17","vendors":["HackerOne"]},"summary":"Attackers can cause denial of service in applications using sshpk by providing crafted invalid public keys that trigger excessive CPU usage.","url":"https://insights.sbomify.com/CVE-2018-3737/"}
