FileZen, published on 17 Feb 2021. An attacker needs administrator access to exploit it, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2021-20655 in the wild and no public exploit code.\n\nAffected product: Soliton Systems K.K. FileZen. 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-2021-20655/ (Markdown: https://insights.sbomify.com/CVE-2021-20655/index.md)","id":"CVE-2021-20655","markdown":"https://insights.sbomify.com/CVE-2021-20655/index.md","name":"CVE-2021-20655","record":{"aliases":["GHSA-2w44-vr82-84c4"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"File transfer software","requires_auth":"high_privilege","summary":"Remote administrators can execute arbitrary OS commands on FileZen servers, requiring an upgrade to mitigate the risk.","user_interaction":"not_required","vuln_class":"command_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"jpcert","cpe":[{"product":"filezen","vendor":"soliton"}],"cvss":{"score":7.2,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-78","name":"Improper Neutralization of Special Elements used in an OS Command"}],"description":"FileZen (V3.0.0 to V4.2.7 and V5.0.0 to V5.0.2) allows a remote attacker with administrator rights to execute arbitrary OS commands 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":"Command injection in FileZen","id":"CVE-2021-20655","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":"Information disclosure in SolarView Compact","id":"CVE-2021-20656"},"packages":[],"prev":{"headline":"Cross-site scripting in Wekan","id":"CVE-2021-20654"},"products":["FileZen"],"published":"2021-02-17","related":[{"cvss_score":8.7,"headline":"Soliton Systems K.K FileZen OS Command Injection","id":"CVE-2026-25108","kev_date_added":"2026-02-24","published":"2026-02-13"},{"cvss_score":9.8,"headline":"Path traversal in FileZen","id":"CVE-2020-5639","kev_date_added":null,"published":"2020-12-14"},{"cvss_score":9.8,"headline":"Command injection in FileZen","id":"CVE-2018-0694","kev_date_added":null,"published":"2018-11-15"},{"cvss_score":7.5,"headline":"Path traversal in FileZen","id":"CVE-2018-0693","kev_date_added":null,"published":"2018-11-15"}],"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":["Soliton Systems K.K."]},"summary":"Remote administrators can execute arbitrary OS commands on FileZen servers, requiring an upgrade to mitigate the risk.","url":"https://insights.sbomify.com/CVE-2021-20655/"}
