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-2016-0733 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- org.apache.ranger:ranger (Maven): affected all versions; fixed in 0.5.1\n- org.apache.ranger:ranger (Maven): affected all versions; fixed in 0.5.1\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-2016-0733/ (Markdown: https://insights.sbomify.com/CVE-2016-0733/index.md)","id":"CVE-2016-0733","markdown":"https://insights.sbomify.com/CVE-2016-0733/index.md","name":"CVE-2016-0733","record":{"aliases":["GHSA-j84c-j8qm-g47r"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Apache Ranger Admin UI","requires_auth":"none","summary":"Remote attackers can bypass authentication in Apache Ranger Admin UI by providing a valid username without a password.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[{"product":"ranger","vendor":"apache"}],"cvss":{"score":9.8,"severity":"critical","source":"nvd","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.0"},"cwes":[{"id":"CWE-287","name":"Improper Authentication"}],"description":"The Admin UI in Apache Ranger before 0.5.1 does not properly handle authentication requests that lack a password, which allows remote attackers to bypass authentication by leveraging knowledge of a valid username.","ecosystems":["Maven"],"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":"The Admin UI in Apache Ranger before 0.5.1 does not properly handle authentication requests that lack a password","id":"CVE-2016-0733","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Maven","product":null,"products":[],"type":"auth_bypass","year":"2016"},"n_packages":2,"n_references":4,"next":{"headline":"Improper Neutralization of Input During Web Page Generation in Apache ActiveMQ","id":"CVE-2016-0734"},"packages":[{"ecosystem":"Maven","fixed":["0.5.1"],"introduced":["0"],"last_affected":[],"package":"org.apache.ranger:ranger","purl":null,"source":"GHSA-j84c-j8qm-g47r"},{"ecosystem":"Maven","fixed":["0.5.1"],"introduced":["0"],"last_affected":[],"package":"org.apache.ranger:ranger","purl":"pkg:maven/org.apache.ranger/ranger","source":"GHSA-j84c-j8qm-g47r"}],"prev":{"headline":"Privilege escalation in n/a","id":"CVE-2016-0732"},"products":["n/a"],"published":"2016-04-12","related":[{"cvss_score":9.8,"headline":"Apache Ranger: OS Command Injection via Username in UnixUserGroupBuilder","id":"CVE-2026-28672","kev_date_added":null,"published":"2026-08-10"},{"cvss_score":9.8,"headline":"Apache Ranger: SQL Injection vulnerability in lookup functionality","id":"CVE-2026-32227","kev_date_added":null,"published":"2026-08-10"},{"cvss_score":9.8,"headline":"Apache Ranger: Privilege Escalation via URL Parameter","id":"CVE-2026-40920","kev_date_added":null,"published":"2026-08-10"},{"cvss_score":9.8,"headline":"Apache Ranger: Remote Code Execution via JDBC URL Injection","id":"CVE-2026-42537","kev_date_added":null,"published":"2026-08-10"},{"cvss_score":9.8,"headline":"Apache Ranger: Remote Code Execution via Arbitrary Class Instantiation","id":"CVE-2026-44416","kev_date_added":null,"published":"2026-08-10"},{"cvss_score":9.8,"headline":"Apache Ranger: Remote Code Execution Vulnerability in GraalScriptEngineCreator","id":"CVE-2026-55799","kev_date_added":null,"published":"2026-08-10"},{"cvss_score":9.8,"headline":"Apache Ranger: Remote Code Execution Vulnerability in NashornScriptEngineCreator","id":"CVE-2025-59059","kev_date_added":null,"published":"2026-03-03"}],"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":"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":"2024-08-05","vendors":["n/a"]},"summary":"Remote attackers can bypass authentication in Apache Ranger Admin UI by providing a valid username without a password.","url":"https://insights.sbomify.com/CVE-2016-0733/"}
