It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2016-6664 in the wild and no public exploit code.\n\nAffected product: Mariadb Mariadb. 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-2016-6664/ (Markdown: https://insights.sbomify.com/CVE-2016-6664/index.md)","id":"CVE-2016-6664","markdown":"https://insights.sbomify.com/CVE-2016-6664/index.md","name":"CVE-2016-6664","record":{"aliases":["ALPINE-CVE-2016-6664","CVE-2016-5617","GHSA-f9x4-3x96-w2vf","UBUNTU-CVE-2016-6664"],"analysis":{"component_type":"database","fix_type":"patch","impacts":["privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":true,"product_category":"MySQL/MariaDB server","requires_auth":"low_privilege","summary":"Local attackers with mysql account access can gain root privileges via symlink attacks on error logs when file-based logging is enabled.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"mariadb","vendor":"mariadb"},{"product":"mysql","vendor":"oracle"},{"product":"percona_server","vendor":"percona"},{"product":"xtradb_cluster","vendor":"percona"}],"cvss":{"score":7,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-59","name":"Improper Link Resolution Before File Access"}],"description":"mysqld_safe in Oracle MySQL through 5.5.51, 5.6.x through 5.6.32, and 5.7.x through 5.7.14; MariaDB; Percona Server before 5.5.51-38.2, 5.6.x before 5.6.32-78-1, and 5.7.x before 5.7.14-8; and Percona XtraDB Cluster before 5.5.41-37.0, 5.6.x before 5.6.32-25.17, and 5.7.x before 5.7.14-26.17, when using file-based logging, allows local users with access to the mysql account to gain root privileges via a symlink attack on error logs and possibly other files.","ecosystems":[],"exploits":{"exploitdb":1,"first_seen":"2016-11-01","github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[{"date":"2016-11-01","kind":"exploitdb","ref":"40679","stars":null,"title":"MySQL / MariaDB / PerconaDB 5.5.x/5.6.x/5.7.x - 'root' System User Privilege Escalation"}],"tier":"poc_unverified"},"has_fix":true,"headline":"Path traversal in n/a","id":"CVE-2016-6664","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"mariadb:mariadb","products":["mariadb:mariadb","oracle:mysql"],"type":"path_traversal","year":"2016"},"n_packages":0,"n_references":15,"next":{"headline":"Hardcoded credentials in n/a","id":"CVE-2016-6667"},"packages":[],"prev":{"headline":"Race condition in n/a","id":"CVE-2016-6663"},"products":["n/a"],"published":"2016-12-13","related":[{"cvss_score":10,"headline":"MariaDB server has unsafe parameter handling in `wsrep_notify_cmd`","id":"CVE-2026-49261","kev_date_added":null,"published":"2026-06-11"},{"cvss_score":9.9,"headline":"MariaDB: Out-of-bound buffer write on in `ST_AsText` of nested GeometryCollections","id":"CVE-2026-85746","kev_date_added":null,"published":"2026-10-16"},{"cvss_score":9.9,"headline":"MariaDB: Use-after-free with a large number of SYS_REFCURSOR's","id":"CVE-2026-85748","kev_date_added":null,"published":"2026-10-16"},{"cvss_score":9.9,"headline":"MariaDB: Numerous issues caused by historical #mysql50# tablename encoding bypass.","id":"CVE-2026-92262","kev_date_added":null,"published":"2026-10-16"},{"cvss_score":9.8,"headline":"Code injection in n/a","id":"CVE-2023-26785","kev_date_added":null,"published":"2024-10-17"},{"cvss_score":8.8,"headline":"MariaDB: GRANT PROXY with empty password incorrectly checks grantor's privileges","id":"CVE-2026-97380","kev_date_added":null,"published":"2026-10-16"},{"cvss_score":8.6,"headline":"Heap-based Buffer Overflow in MariaDB","id":"CVE-2026-32710","kev_date_added":null,"published":"2026-03-20"}],"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)"},{"class":"attribution","licence":"GPL-2.0-or-later","name":"Exploit-DB"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-06","vendors":["n/a"]},"summary":"Local attackers with mysql account access can gain root privileges via symlink attacks on error logs when file-based logging is enabled.","url":"https://insights.sbomify.com/CVE-2016-6664/"}
