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-2021-41638 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-2021-41638/ (Markdown: https://insights.sbomify.com/CVE-2021-41638/index.md)","id":"CVE-2021-41638","markdown":"https://insights.sbomify.com/CVE-2021-41638/index.md","name":"CVE-2021-41638","record":{"aliases":["GHSA-m56w-5xpw-w7wc"],"analysis":{"component_type":"server_software","fix_type":"no_fix_stated","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"MELAG FTP Server","requires_auth":"none","summary":"Remote attackers can access local files on MELAG FTP Server by using only a valid username, bypassing complete authentication checks.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"ftp_server","vendor":"melag"}],"cvss":{"score":7.5,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-287","name":"Improper Authentication"}],"description":"The authentication checks of the MELAG FTP Server in version 2.2.0.4 are incomplete, which allows a remote attacker to access local files only by using a valid username.","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":"Auth bypass in n/a","id":"CVE-2021-41638","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"auth_bypass","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"Information disclosure in n/a","id":"CVE-2021-41639"},"packages":[],"prev":{"headline":"Information disclosure in n/a","id":"CVE-2021-41637"},"products":["n/a"],"published":"2022-06-24","related":[{"cvss_score":8.8,"headline":"Privilege escalation in n/a","id":"CVE-2021-41635","kev_date_added":null,"published":"2022-06-24"},{"cvss_score":7.1,"headline":"Information disclosure in n/a","id":"CVE-2021-41637","kev_date_added":null,"published":"2022-06-24"},{"cvss_score":6.5,"headline":"Path traversal in n/a","id":"CVE-2021-41636","kev_date_added":null,"published":"2022-06-24"},{"cvss_score":5.5,"headline":"Information disclosure in n/a","id":"CVE-2021-41639","kev_date_added":null,"published":"2022-06-24"},{"cvss_score":5.3,"headline":"Information disclosure in n/a","id":"CVE-2021-41634","kev_date_added":null,"published":"2022-06-24"}],"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":"2024-08-04","vendors":["n/a"]},"summary":"Remote attackers can access local files on MELAG FTP Server by using only a valid username, bypassing complete authentication checks.","url":"https://insights.sbomify.com/CVE-2021-41638/"}
