Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2020-26064 in the wild and no public exploit code.\n\nAffected product: Cisco Catalyst Sd-Wan 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-2020-26064/ (Markdown: https://insights.sbomify.com/CVE-2020-26064/index.md)","id":"CVE-2020-26064","markdown":"https://insights.sbomify.com/CVE-2020-26064/index.md","name":"CVE-2020-26064","record":{"aliases":["GHSA-rvrv-6xrw-v985"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["data_read","data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"Cisco SD-WAN vManage","requires_auth":"low_privilege","summary":"Authenticated attackers can read and write files via XXE in Cisco SD-WAN vManage by tricking users into importing malicious XML.","user_interaction":"not_required","vuln_class":"xxe"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"cisco","cpe":[{"product":"catalyst_sd-wan_manager","vendor":"cisco"}],"cvss":{"score":6.5,"severity":"medium","source":"cna","vector":"CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N","version":"3.0"},"cwes":[{"id":"CWE-611","name":"Improper Restriction of XML External Entity Reference"}],"description":"A vulnerability in the web UI of Cisco SD-WAN vManage Software could allow an authenticated, remote attacker to gain read and write access to information that is stored on an affected system.\r\n The vulnerability is due to improper handling of XML External Entity (XXE) entries when parsing certain XML files.
