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-2024-39223 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- github.com/ginuerzh/gost (Go): affected all versions; no fix listed\n- github.com/ginuerzh/gost (Go): affected all versions up to 2.11.5; no fix listed\n- github.com/ginuerzh/gost (Go): affected all versions up to 2.11.5; no fix listed\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-2024-39223/ (Markdown: https://insights.sbomify.com/CVE-2024-39223/index.md)","id":"CVE-2024-39223","markdown":"https://insights.sbomify.com/CVE-2024-39223/index.md","name":"CVE-2024-39223","record":{"aliases":["GHSA-8wxx-35qc-vp6r","GO-2024-3224","UBUNTU-CVE-2024-39223"],"analysis":{"component_type":"library","fix_type":"patch","impacts":["security_bypass","data_read"],"network_reachable":"yes","non_default_config":true,"product_category":"Go SSH library","requires_auth":"none","summary":"Attackers can bypass SSH authentication and intercept communications if the HostKeyCallback is configured to ignore host keys.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[],"cvss":{"score":9.8,"severity":"critical","source":"cisa-adp","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-639","name":"Authorization Bypass Through User-Controlled Key"}],"description":"An authentication bypass in the SSH service of gost v2.11.5 allows attackers to intercept communications via setting the HostKeyCallback function to ssh.InsecureIgnoreHostKey","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":"Missing key verification in gost","id":"CVE-2024-39223","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Go","product":null,"products":[],"type":"auth_bypass","year":"2024"},"n_packages":3,"n_references":3,"next":{"headline":"Other in n/a","id":"CVE-2024-39225"},"packages":[{"ecosystem":"Go","fixed":[],"introduced":["0"],"last_affected":[],"package":"github.com/ginuerzh/gost","purl":"pkg:golang/github.com/ginuerzh/gost","source":"GO-2024-3224"},{"ecosystem":"Go","fixed":[],"introduced":["0"],"last_affected":["2.11.5"],"package":"github.com/ginuerzh/gost","purl":null,"source":"GHSA-8wxx-35qc-vp6r"},{"ecosystem":"Go","fixed":[],"introduced":["0"],"last_affected":["2.11.5"],"package":"github.com/ginuerzh/gost","purl":"pkg:golang/github.com/ginuerzh/gost","source":"GHSA-8wxx-35qc-vp6r"}],"prev":{"headline":"Information disclosure in n/a","id":"CVE-2024-39220"},"products":["n/a"],"published":"2024-07-03","related":[],"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":"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":"2024-10-25","vendors":["n/a"]},"summary":"Attackers can bypass SSH authentication and intercept communications if the HostKeyCallback is configured to ignore host keys.","url":"https://insights.sbomify.com/CVE-2024-39223/"}
