An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2020-4449 in the wild and no public exploit code.\n\nAffected product: Ibm Websphere Application 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-2020-4449/ (Markdown: https://insights.sbomify.com/CVE-2020-4449/index.md)","id":"CVE-2020-4449","markdown":"https://insights.sbomify.com/CVE-2020-4449/index.md","name":"CVE-2020-4449","record":{"aliases":["GHSA-r6mf-gg9c-722f"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"WebSphere Application Server","requires_auth":"none","summary":"Remote attackers can obtain sensitive information from IBM WebSphere Application Server by sending specially crafted serialized objects.","user_interaction":"not_required","vuln_class":"deserialization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"ibm","cpe":[{"product":"websphere_application_server","vendor":"ibm"}],"cvss":{"score":7.5,"severity":"high","source":"cna","vector":"CVSS:3.0/A:N/I:N/S:U/PR:N/C:H/AV:N/AC:L/UI:N/RC:C/E:U/RL:O","version":"3.0"},"cwes":[{"id":"CWE-502","name":"Deserialization of Untrusted Data"}],"description":"IBM WebSphere Application Server 7.0, 8.0, 8.5, and 9.0 traditional could allow a remote attacker to obtain sensitive information with a specially-crafted sequence of serialized objects.
