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-2021-20618 in the wild and no public exploit code.\n\nAffected product: Seeds Co.,Ltd. acmailer and acmailer DB. 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-2021-20618/ (Markdown: https://insights.sbomify.com/CVE-2021-20618/index.md)","id":"CVE-2021-20618","markdown":"https://insights.sbomify.com/CVE-2021-20618/index.md","name":"CVE-2021-20618","record":{"aliases":["GHSA-vp5j-p4fm-qpqr"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["privilege_escalation","data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"acmailer mail server","requires_auth":"none","summary":"Remote attackers can bypass authentication and gain administrative privileges to access sensitive server information in acmailer.","user_interaction":"not_required","vuln_class":"privilege_escalation"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"jpcert","cpe":[{"product":"acmailer","vendor":"acmailer"},{"product":"acmailer_db","vendor":"acmailer"}],"cvss":{"score":9.8,"severity":"critical","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-269","name":"Improper Privilege Management"}],"description":"Privilege chaining vulnerability in acmailer ver. 4.0.2 and earlier, and acmailer DB ver. 1.1.4 and earlier allows remote attackers to bypass authentication and to gain an administrative privilege which may result in obtaining the sensitive information on the server via unspecified vectors.","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":"Privilege escalation in acmailer and acmailer DB","id":"CVE-2021-20618","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"privilege_escalation","year":"2021"},"n_packages":0,"n_references":2,"next":{"headline":"Cross-site scripting in GROWI v4.2 Series","id":"CVE-2021-20619"},"packages":[],"prev":{"headline":"Command injection in acmailer and acmailer DB","id":"CVE-2021-20617"},"products":["acmailer and acmailer DB"],"published":"2021-01-14","related":[{"cvss_score":9.8,"headline":"Command injection in acmailer and acmailer DB","id":"CVE-2021-20617","kev_date_added":null,"published":"2021-01-14"}],"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":"2024-08-03","vendors":["Seeds Co.,Ltd."]},"summary":"Remote attackers can bypass authentication and gain administrative privileges to access sensitive server information in acmailer.","url":"https://insights.sbomify.com/CVE-2021-20618/"}
