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-1999-1231 in the wild and no public exploit code.\n\nAffected product: n/a. 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-1999-1231/ (Markdown: https://insights.sbomify.com/CVE-1999-1231/index.md)","id":"CVE-1999-1231","markdown":"https://insights.sbomify.com/CVE-1999-1231/index.md","name":"CVE-1999-1231","record":{"aliases":["GHSA-7g97-5hq7-x7mm"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"SSH server","requires_auth":"none","summary":"Remote attackers can enumerate valid user accounts on SSH servers by observing differences in password prompt behavior for valid versus invalid usernames.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"ssh2","vendor":"ssh"}],"cvss":{"score":5,"severity":"medium","source":"nvd","vector":"AV:N/AC:L/Au:N/C:P/I:N/A:N","version":"2.0"},"cwes":[],"description":"ssh 2.0.12, and possibly other versions, allows valid user names to attempt to enter the correct password multiple times, but only prompts an invalid user name for a password once, which allows remote attackers to determine user account names on the server.","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":"Information disclosure in n/a","id":"CVE-1999-1231","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"information_disclosure","year":"1999"},"n_packages":0,"n_references":2,"next":{"headline":"Path traversal in n/a","id":"CVE-1999-1232"},"packages":[],"prev":{"headline":"Denial of service in n/a","id":"CVE-1999-1230"},"products":["n/a"],"published":"2001-09-12","related":[{"cvss_score":10,"headline":"Memory corruption in n/a","id":"CVE-2002-1645","kev_date_added":null,"published":"2005-03-28"},{"cvss_score":7.5,"headline":"Information disclosure in n/a","id":"CVE-1999-1029","kev_date_added":null,"published":"2001-09-12"},{"cvss_score":7.2,"headline":"Privilege escalation in n/a","id":"CVE-2002-1644","kev_date_added":null,"published":"2005-03-28"},{"cvss_score":5,"headline":"Denial of service in n/a","id":"CVE-2001-0364","kev_date_added":null,"published":"2002-03-09"},{"cvss_score":4.6,"headline":"Privilege escalation in n/a","id":"CVE-1999-1159","kev_date_added":null,"published":"2002-03-09"}],"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)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-01","vendors":["n/a"]},"summary":"Remote attackers can enumerate valid user accounts on SSH servers by observing differences in password prompt behavior for valid versus invalid usernames.","url":"https://insights.sbomify.com/CVE-1999-1231/"}
