Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2016-2167 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-2016-2167/ (Markdown: https://insights.sbomify.com/CVE-2016-2167/index.md)","id":"CVE-2016-2167","markdown":"https://insights.sbomify.com/CVE-2016-2167/index.md","name":"CVE-2016-2167","record":{"aliases":["DEBIAN-CVE-2016-2167","GHSA-4j43-22vc-mh3h","UBUNTU-CVE-2016-2167"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["security_bypass","data_read"],"network_reachable":"yes","non_default_config":true,"product_category":"Subversion server","requires_auth":"low_privilege","summary":"Remote attackers can bypass authentication and access restricted repositories by exploiting a prefix matching flaw in Cyrus SASL realm validation.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[{"product":"subversion","vendor":"apache"}],"cvss":{"score":6.8,"severity":"medium","source":"nvd","vector":"CVSS:3.0/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:N","version":"3.0"},"cwes":[{"id":"CWE-284","name":"Improper Access Control"}],"description":"The canonicalize_username function in svnserve/cyrus_auth.c in Apache Subversion before 1.8.16 and 1.9.x before 1.9.4, when Cyrus SASL authentication is used, allows remote attackers to authenticate and bypass intended access restrictions via a realm string that is a prefix of an expected repository realm string.","ecosystems":[],"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":"Auth bypass in n/a","id":"CVE-2016-2167","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"auth_bypass","year":"2016"},"n_packages":0,"n_references":12,"next":{"headline":"Null dereference in n/a","id":"CVE-2016-2168"},"packages":[],"prev":{"headline":"Moderate severity vulnerability that affects org.apache.qpid:proton-j","id":"CVE-2016-2166"},"products":["n/a"],"published":"2016-05-05","related":[{"cvss_score":9.8,"headline":"A maliciously constructed svn+ssh:// URL would cause Subversion clients before 1.8.19, 1.9.x before 1.9.7, and 1.10.0.x through 1.10.0-alpha","id":"CVE-2017-9800","kev_date_added":null,"published":"2017-08-11"},{"cvss_score":8.8,"headline":"Denial of service in n/a","id":"CVE-2013-4246","kev_date_added":null,"published":"2017-10-30"},{"cvss_score":8.6,"headline":"Integer overflow in n/a","id":"CVE-2015-5259","kev_date_added":null,"published":"2016-01-08"},{"cvss_score":8.2,"headline":"Apache Subversion: Command line argument injection on Windows platforms","id":"CVE-2024-45720","kev_date_added":null,"published":"2024-10-09"},{"cvss_score":7.8,"headline":"Denial of service in n/a","id":"CVE-2015-0202","kev_date_added":null,"published":"2015-04-08"},{"cvss_score":7.8,"headline":"Denial of service in n/a","id":"CVE-2013-2112","kev_date_added":null,"published":"2013-07-31"},{"cvss_score":7.6,"headline":"Integer overflow in n/a","id":"CVE-2015-5343","kev_date_added":null,"published":"2016-04-14"}],"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":"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 and access restricted repositories by exploiting a prefix matching flaw in Cyrus SASL realm validation.","url":"https://insights.sbomify.com/CVE-2016-2167/"}
