An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: Yes. Attackers have exploited CVE-2020-2883 in the wild since at least 7 Jan 2025.\n\nAffected product: Oracle Weblogic Server. 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-2020-2883/ (Markdown: https://insights.sbomify.com/CVE-2020-2883/index.md)","id":"CVE-2020-2883","markdown":"https://insights.sbomify.com/CVE-2020-2883/index.md","name":"CVE-2020-2883","record":{"aliases":["GHSA-9x8q-p3qp-r24w"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["code_execution","privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"WebLogic Server","requires_auth":"none","summary":"Unauthenticated attackers can take over Oracle WebLogic Server via network access using IIOP or T3 protocols.","user_interaction":"not_required","vuln_class":"other"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"oracle","cpe":[{"product":"weblogic_server","vendor":"oracle"}],"cvss":{"score":9.8,"severity":"critical","source":"cna","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.0"},"cwes":[],"description":"Vulnerability in the Oracle WebLogic Server product of Oracle Fusion Middleware (component: Core).
