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-2021-20617 exists.\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-2021-20617/ (Markdown: https://insights.sbomify.com/CVE-2021-20617/index.md)","id":"CVE-2021-20617","markdown":"https://insights.sbomify.com/CVE-2021-20617/index.md","name":"CVE-2021-20617","record":{"aliases":["GHSA-6456-hr4p-p4pq"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["code_execution","privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"acmailer mail server","requires_auth":"none","summary":"Remote attackers can execute arbitrary OS commands or gain administrative privileges in acmailer, leading to potential server compromise.","user_interaction":"not_required","vuln_class":"command_injection"},"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":[],"description":"Improper access control vulnerability in acmailer ver. 4.0.1 and earlier, and acmailer DB ver. 1.1.3 and earlier allows remote attackers to execute an arbitrary OS command, or 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":1,"refs":[{"date":null,"kind":"nuclei","ref":"http/cves/2021/CVE-2021-20617.yaml","stars":null,"title":"Acmailer - Improper Access Control to OS Command Injection"}],"tier":"weaponised"},"has_fix":null,"headline":"Command injection in acmailer and acmailer DB","id":"CVE-2021-20617","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"command_injection","year":"2021"},"n_packages":0,"n_references":2,"next":{"headline":"Privilege escalation in acmailer and acmailer DB","id":"CVE-2021-20618"},"packages":[],"prev":{"headline":"Privilege escalation in SKYSEA Client View","id":"CVE-2021-20616"},"products":["acmailer and acmailer DB"],"published":"2021-01-14","related":[{"cvss_score":9.8,"headline":"Privilege escalation in acmailer and acmailer DB","id":"CVE-2021-20618","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":"FIRST CVSS licence","name":"CVSS (FIRST)"},{"class":"attribution","licence":"MIT","name":"Nuclei templates"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-03","vendors":["Seeds Co.,Ltd."]},"summary":"Remote attackers can execute arbitrary OS commands or gain administrative privileges in acmailer, leading to potential server compromise.","url":"https://insights.sbomify.com/CVE-2021-20617/"}
