An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2023-21893 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- Oracle.ManagedDataAccess (NuGet): affected from 19.0.0; fixed in 19.18.0\n- Oracle.ManagedDataAccess (NuGet): affected from 19.0.0; fixed in 19.18.0\n- Oracle.ManagedDataAccess (NuGet): affected from 21.0.0; fixed in 21.9.0\n- Oracle.ManagedDataAccess (NuGet): affected from 21.0.0; fixed in 21.9.0\n- Oracle.ManagedDataAccess.Core (NuGet): affected from 2.19.0; fixed in 2.19.180\n- Oracle.ManagedDataAccess.Core (NuGet): affected from 2.19.0; fixed in 2.19.180\n- Oracle.ManagedDataAccess.Core (NuGet): affected from 3.21.0; fixed in 3.21.90\n- Oracle.ManagedDataAccess.Core (NuGet): affected from 3.21.0; fixed in 3.21.90\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-2023-21893/ (Markdown: https://insights.sbomify.com/CVE-2023-21893/index.md)","id":"CVE-2023-21893","markdown":"https://insights.sbomify.com/CVE-2023-21893/index.md","name":"CVE-2023-21893","record":{"aliases":["GHSA-5pm2-9mr2-3frq"],"analysis":{"component_type":"database","fix_type":"patch","impacts":["code_execution","privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"Oracle Data Provider .NET","requires_auth":"none","summary":"An unauthenticated attacker can compromise the Oracle Data Provider for .NET via network access, leading to full system takeover.","user_interaction":"required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"oracle","cpe":[{"product":"database_server","vendor":"oracle"}],"cvss":{"score":7.5,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-284","name":"Improper Access Control"}],"description":"Vulnerability in the Oracle Data Provider for .NET component of Oracle Database Server.
