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-2020-7221 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- mariadb (Bitnami): affected from 10.4.7; fixed in 10.4.12\n- mariadb-min (Bitnami): affected from 10.4.7 up to 10.4.11; no fix listed\n- mysql-client (Bitnami): affected from 10.4.7; fixed in 10.4.12\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-2020-7221/ (Markdown: https://insights.sbomify.com/CVE-2020-7221/index.md)","id":"CVE-2020-7221","markdown":"https://insights.sbomify.com/CVE-2020-7221/index.md","name":"CVE-2020-7221","record":{"aliases":["BIT-mariadb-2020-7221","BIT-mariadb-min-2020-7221","BIT-mysql-client-2020-7221","GHSA-3xr8-q83f-2wqp","UBUNTU-CVE-2020-7221"],"analysis":{"component_type":"database","fix_type":"patch","impacts":["privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"MariaDB database","requires_auth":"low_privilege","summary":"A local attacker with mysql user access can escalate privileges to root via unsafe file permissions in MariaDB's installation script.","user_interaction":"not_required","vuln_class":"privilege_escalation"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"mariadb","vendor":"mariadb"}],"cvss":{"score":7.8,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:L/AC:L/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":"mysql_install_db in MariaDB 10.4.7 through 10.4.11 allows privilege escalation from the mysql user account to root because chown and chmod are performed unsafely, as demonstrated by a symlink attack on a chmod 04755 of auth_pam_tool_dir/auth_pam_tool.
