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-2018-18861 in the wild and no public exploit code.\n\nAffected product: Pcman Ftp Server. 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-2018-18861/ (Markdown: https://insights.sbomify.com/CVE-2018-18861/index.md)","id":"CVE-2018-18861","markdown":"https://insights.sbomify.com/CVE-2018-18861/index.md","name":"CVE-2018-18861","record":{"aliases":["GHSA-9f7c-p7m5-r79c"],"analysis":{"component_type":"server_software","fix_type":"no_fix_stated","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"FTP server","requires_auth":"none","summary":"A buffer overflow in PCMan FTP Server allows remote attackers to execute arbitrary code via the APPE command.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"ftp_server","vendor":"pcman"}],"cvss":{"score":9.8,"severity":"critical","source":"nvd","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.0"},"cwes":[{"id":"CWE-119","name":"Improper Restriction of Operations within the Bounds of a Memory Buffer"}],"description":"Buffer overflow in PCMan FTP Server 2.0.7 allows for remote code execution via the APPE command.","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":"Memory corruption in n/a","id":"CVE-2018-18861","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"pcman:ftp_server","products":["pcman:ftp_server"],"type":"memory_corruption","year":"2018"},"n_packages":0,"n_references":1,"next":{"headline":"Missing authorization in n/a","id":"CVE-2018-18862"},"packages":[],"prev":{"headline":"Privilege escalation in n/a","id":"CVE-2018-18860"},"products":["n/a"],"published":"2018-11-20","related":[{"cvss_score":10,"headline":"Memory corruption in n/a","id":"CVE-2013-4730","kev_date_added":null,"published":"2014-05-15"},{"cvss_score":7.8,"headline":"Path traversal in n/a","id":"CVE-2015-7601","kev_date_added":null,"published":"2015-09-29"},{"cvss_score":6.9,"headline":"PCMan FTP Server NOOP Command buffer overflow","id":"CVE-2025-5634","kev_date_added":null,"published":"2025-06-05"},{"cvss_score":6.9,"headline":"PCMan FTP Server PLS Command buffer overflow","id":"CVE-2025-5635","kev_date_added":null,"published":"2025-06-05"},{"cvss_score":6.9,"headline":"PCMan FTP Server SET Command buffer overflow","id":"CVE-2025-5636","kev_date_added":null,"published":"2025-06-05"},{"cvss_score":6.9,"headline":"PCMan FTP Server SYSTEM Command buffer overflow","id":"CVE-2025-5637","kev_date_added":null,"published":"2025-06-05"}],"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":"A buffer overflow in PCMan FTP Server allows remote attackers to execute arbitrary code via the APPE command.","url":"https://insights.sbomify.com/CVE-2018-18861/"}
