An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2019-18217 exists.\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-2019-18217/ (Markdown: https://insights.sbomify.com/CVE-2019-18217/index.md)","id":"CVE-2019-18217","markdown":"https://insights.sbomify.com/CVE-2019-18217/index.md","name":"CVE-2019-18217","record":{"aliases":["DEBIAN-CVE-2019-18217","DLA-1974-1","DSA-4559-1","GHSA-5446-jrwr-x7c6","UBUNTU-CVE-2019-18217"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"FTP server","requires_auth":"none","summary":"Remote unauthenticated attackers can cause a denial of service in ProFTPD by sending overly long commands, triggering an infinite loop in the child process.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"proftpd","vendor":"proftpd"}],"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-835","name":"Loop with Unreachable Exit Condition"}],"description":"ProFTPD before 1.3.6b and 1.3.7rc before 1.3.7rc2 allows remote unauthenticated denial-of-service due to incorrect handling of overly long commands because main.c in a child process enters an infinite loop.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":1,"refs":[{"date":null,"kind":"nuclei","ref":"network/cves/2019/CVE-2019-18217.yaml","stars":null,"title":"ProFTPD \u003c 1.3.6b - Remote Unauthenticated DoS"}],"tier":"weaponised"},"has_fix":true,"headline":"Denial of service in n/a","id":"CVE-2019-18217","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2019"},"n_packages":0,"n_references":14,"next":{"headline":"Memory corruption in n/a","id":"CVE-2019-18218"},"packages":[],"prev":{"headline":"Security feature bypass in n/a","id":"CVE-2019-18216"},"products":["n/a"],"published":"2019-10-21","related":[{"cvss_score":10,"headline":"Memory corruption in n/a","id":"CVE-2010-4221","kev_date_added":null,"published":"2010-11-09"},{"cvss_score":9.3,"headline":"ProFTPD 1.3.3c Backdoor Command Execution","id":"CVE-2010-20103","kev_date_added":null,"published":"2025-08-20"},{"cvss_score":9,"headline":"Use after free in n/a","id":"CVE-2011-4130","kev_date_added":null,"published":"2011-12-06"},{"cvss_score":8.7,"headline":"ProFTPD mod_sftp Heap Buffer Overflow via SFTP Packet Reassembly","id":"CVE-2026-63090","kev_date_added":null,"published":"2026-07-20"},{"cvss_score":8.6,"headline":"ProFTPD ACL Bypass via /proc/self/root Path Prefix in RNFR","id":"CVE-2026-35025","kev_date_added":null,"published":"2026-06-24"},{"cvss_score":8.1,"headline":"SQL injection in ProFTPD","id":"CVE-2026-42167","kev_date_added":null,"published":"2026-04-28"},{"cvss_score":7.8,"headline":"Memory corruption in n/a","id":"CVE-2004-0346","kev_date_added":null,"published":"2004-03-18"}],"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)"},{"class":"attribution","licence":"MIT","name":"Nuclei templates"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-05","vendors":["n/a"]},"summary":"Remote unauthenticated attackers can cause a denial of service in ProFTPD by sending overly long commands, triggering an infinite loop in the child process.","url":"https://insights.sbomify.com/CVE-2019-18217/"}
