Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2020-4945 in the wild and no public exploit code.\n\nAffected product: Ibm Db2. 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-2020-4945/ (Markdown: https://insights.sbomify.com/CVE-2020-4945/index.md)","id":"CVE-2020-4945","markdown":"https://insights.sbomify.com/CVE-2020-4945/index.md","name":"CVE-2020-4945","record":{"aliases":["GHSA-fhg4-xhw8-92hr"],"analysis":{"component_type":"database","fix_type":"patch","impacts":["data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"IBM Db2 database","requires_auth":"low_privilege","summary":"An authenticated user can overwrite arbitrary files in IBM Db2 due to improper group permissions, allowing unauthorized data modification.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"ibm","cpe":[{"product":"db2","vendor":"ibm"}],"cvss":{"score":6.5,"severity":"medium","source":"cna","vector":"CVSS:3.0/A:N/UI:N/I:H/AC:L/PR:L/AV:N/C:N/S:U/RL:O/E:U/RC:C","version":"3.0"},"cwes":[{"id":"CWE-732","name":"Incorrect Permission Assignment for Critical Resource"}],"description":"IBM Db2 for Linux, UNIX and Windows (includes Db2 Connect Server) 11.5 could allow an authenticated user to overwrite arbirary files due to improper group permissions.
