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-2017-3206 in the wild and no public exploit code.\n\nAffected product: Exadel Flamingo amf-serializer. 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-2017-3206/ (Markdown: https://insights.sbomify.com/CVE-2017-3206/index.md)","id":"CVE-2017-3206","markdown":"https://insights.sbomify.com/CVE-2017-3206/index.md","name":"CVE-2017-3206","record":{"aliases":["GHSA-685x-q7j3-8c52"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["data_read","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Java AMF3 serializer","requires_auth":"none","summary":"An attacker can exploit XML external entity references in AMF3 messages to read sensitive data or cause denial of service.","user_interaction":"not_required","vuln_class":"xxe"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"certcc","cpe":[{"product":"flamingo","vendor":"exadel"}],"cvss":{"score":9.8,"severity":"critical","source":"nvd","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.0"},"cwes":[{"id":"CWE-611","name":"Improper Restriction of XML External Entity Reference"}],"description":"The Java implementation of AMF3 deserializers used by Flamingo amf-serializer by Exadel, version 2.2.0, allows external entity references (XXEs) from XML documents embedded within AMF3 messages.
