Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2020-3539 in the wild and no public exploit code.\n\nAffected product: Cisco Data Center Network Manager. 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-2020-3539/ (Markdown: https://insights.sbomify.com/CVE-2020-3539/index.md)","id":"CVE-2020-3539","markdown":"https://insights.sbomify.com/CVE-2020-3539/index.md","name":"CVE-2020-3539","record":{"aliases":["GHSA-x9cp-m9m5-f8xr"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["data_read","data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"Data Center Network Manager","requires_auth":"low_privilege","summary":"Low-privileged attackers can view, modify, and delete administrative templates in Cisco DCNM due to missing authorization checks.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"cisco","cpe":[{"product":"prime_data_center_network_manager","vendor":"cisco"}],"cvss":{"score":6.3,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:L/RL:X/RC:X/E:X","version":"3.1"},"cwes":[{"id":"CWE-285","name":"Improper Authorization"}],"description":"A vulnerability in the web-based management interface of Cisco Data Center Network Manager (DCNM) could allow an authenticated, remote attacker to view, modify, and delete data without proper authorization.\r\nThe vulnerability is due to a failure to limit access to resources that are intended for users with Administrator privileges.
