Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2020-27128 in the wild and no public exploit code.\n\nAffected product: Cisco SD-WAN vManage. 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-2020-27128/ (Markdown: https://insights.sbomify.com/CVE-2020-27128/index.md)","id":"CVE-2020-27128","markdown":"https://insights.sbomify.com/CVE-2020-27128/index.md","name":"CVE-2020-27128","record":{"aliases":["GHSA-vgpq-9fqj-mrjr"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["data_modify","code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"SD-WAN management software","requires_auth":"low_privilege","summary":"Authenticated attackers can exploit improper API validation to perform directory traversal and write arbitrary files to the system.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"cisco","cpe":[{"product":"sd-wan","vendor":"cisco"}],"cvss":{"score":6.5,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-22","name":"Improper Limitation of a Pathname to a Restricted Directory"}],"description":"A vulnerability in the application data endpoints of Cisco SD-WAN vManage Software could allow an authenticated, remote attacker to write arbitrary files to an affected system.
