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-2017-2659 in the wild and no public exploit code.\n\nAffected product: [UNKNOWN] dropbear. 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-2017-2659/ (Markdown: https://insights.sbomify.com/CVE-2017-2659/index.md)","id":"CVE-2017-2659","markdown":"https://insights.sbomify.com/CVE-2017-2659/index.md","name":"CVE-2017-2659","record":{"aliases":["DEBIAN-CVE-2017-2659","GHSA-m7fh-9pv8-fwc2"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":true,"product_category":"SSH server","requires_auth":"none","summary":"An attacker can determine valid usernames on Dropbear SSH servers with GSSAPI enabled by observing authentication failure counts.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[{"product":"dropbear_ssh","vendor":"dropbear_ssh_project"}],"cvss":{"score":5.3,"severity":"medium","source":"cna","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N","version":"3.0"},"cwes":[{"id":"CWE-287","name":"Improper Authentication"},{"id":"CWE-209","name":"Generation of Error Message Containing Sensitive Information"}],"description":"It was found that dropbear before version 2013.59 with GSSAPI leaks whether given username is valid or invalid.
