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-2022-28357 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- github.com/nats-io/nats-server (Go): affected all versions; no fix listed\n- github.com/nats-io/nats-server (Go): affected from 2.2.0; fixed in 2.7.4\n- github.com/nats-io/nats-server (Go): affected from 2.2.0; fixed in 2.7.4\n- github.com/nats-io/nats-server/v2 (Go): affected from 2.2.0; fixed in 2.7.4\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-2022-28357/ (Markdown: https://insights.sbomify.com/CVE-2022-28357/index.md)","id":"CVE-2022-28357","markdown":"https://insights.sbomify.com/CVE-2022-28357/index.md","name":"CVE-2022-28357","record":{"aliases":["GHSA-vpjc-4jcv-jc29","GO-2023-2066","UBUNTU-CVE-2022-28357"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["data_read","data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"NATS server","requires_auth":"none","summary":"An attacker with a management account can perform directory traversal to read or modify files on the NATS server.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"nats-server","vendor":"linuxfoundation"}],"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-22","name":"Improper Limitation of a Pathname to a Restricted Directory"}],"description":"NATS nats-server 2.2.0 through 2.7.4 allows directory traversal because of an unintended path to a management action from a management account.","ecosystems":["Go"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"NATS nats-server allows directory traversal via unintended path to a management action","id":"CVE-2022-28357","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Go","product":null,"products":[],"type":"path_traversal","year":"2022"},"n_packages":4,"n_references":2,"next":{"headline":"Cross-site scripting in n/a","id":"CVE-2022-28363"},"packages":[{"ecosystem":"Go","fixed":[],"introduced":["0"],"last_affected":[],"package":"github.com/nats-io/nats-server","purl":"pkg:golang/github.com/nats-io/nats-server","source":"GO-2023-2066"},{"ecosystem":"Go","fixed":["2.7.4"],"introduced":["2.2.0"],"last_affected":[],"package":"github.com/nats-io/nats-server","purl":null,"source":"GHSA-vpjc-4jcv-jc29"},{"ecosystem":"Go","fixed":["2.7.4"],"introduced":["2.2.0"],"last_affected":[],"package":"github.com/nats-io/nats-server","purl":"pkg:golang/github.com/nats-io/nats-server","source":"GHSA-vpjc-4jcv-jc29"},{"ecosystem":"Go","fixed":["2.7.4"],"introduced":["2.2.0"],"last_affected":[],"package":"github.com/nats-io/nats-server/v2","purl":"pkg:golang/github.com/nats-io/nats-server/v2","source":"GO-2023-2066"}],"prev":{"headline":"Denial of service in n/a","id":"CVE-2022-28356"},"products":["n/a"],"published":"2023-09-19","related":[{"cvss_score":8.8,"headline":"NATS Server: Route API Auth Bypass","id":"CVE-2026-58253","kev_date_added":null,"published":"2026-07-08"},{"cvss_score":8.8,"headline":"Incorrect Authorization in NATS nats-server","id":"CVE-2022-24450","kev_date_added":null,"published":"2022-02-08"},{"cvss_score":8.6,"headline":"NATS has MQTT plaintext password disclosure","id":"CVE-2026-33216","kev_date_added":null,"published":"2026-03-25"},{"cvss_score":7.7,"headline":"NATS Server: Remote crash via integer overflow in Connz pagination","id":"CVE-2026-58207","kev_date_added":null,"published":"2026-07-08"},{"cvss_score":7.5,"headline":"NATS Server: MQTT partial CONNECT packets can exhaust pre-auth memory","id":"CVE-2026-58210","kev_date_added":null,"published":"2026-07-08"},{"cvss_score":7.5,"headline":"NATS Server: Pre-auth server crash via double INFO in leafnode handshake","id":"CVE-2026-58250","kev_date_added":null,"published":"2026-07-08"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"class":"attribution","licence":"CC BY 4.0","name":"Go Vulnerability Database","prefix":"GO"},{"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":"yes","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2024-09-25","vendors":["n/a"]},"summary":"An attacker with a management account can perform directory traversal to read or modify files on the NATS server.","url":"https://insights.sbomify.com/CVE-2022-28357/"}
