An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2020-3466 in the wild and no public exploit code.\n\nAffected product: Cisco Digital Network Architecture Center (DNA Center). 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-2020-3466/ (Markdown: https://insights.sbomify.com/CVE-2020-3466/index.md)","id":"CVE-2020-3466","markdown":"https://insights.sbomify.com/CVE-2020-3466/index.md","name":"CVE-2020-3466","record":{"aliases":["GHSA-72j8-j6qp-6pfv"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["code_execution","data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Cisco DNA Center","requires_auth":"none","summary":"Unauthenticated attackers can execute arbitrary scripts or access sensitive data via XSS in Cisco DNA Center's web interface.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"cisco","cpe":[{"product":"catalyst_center","vendor":"cisco"}],"cvss":{"score":4.7,"severity":"medium","source":"cna","vector":"CVSS:3.0/AV:N/AC:H/PR:N/UI:R/S:C/C:L/I:L/A:N","version":"3.0"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"Multiple vulnerabilities in the web-based management interface of Cisco DNA Center software could allow an unauthenticated, remote attacker to conduct a cross-site scripting (XSS) attack against a user of the interface of an affected device. The vulnerabilities exist because the web-based management interface on an affected device does not properly validate user-supplied input. An attacker could exploit these vulnerabilities by persuading a user of the interface to click a crafted link. A successful exploit could allow the attacker to execute arbitrary script code in the context of the affected interface or access sensitive, browser-based information.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Cisco DNA Center Cross-Site Scripting Vulnerabilities","id":"CVE-2020-3466","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2020"},"n_packages":0,"n_references":1,"next":{"headline":"Cisco Identity Services Engine Authorization Bypass Vulnerability","id":"CVE-2020-3467"},"packages":[],"prev":{"headline":"Cisco IOS XE Software Ethernet Frame Denial of Service Vulnerability","id":"CVE-2020-3465"},"products":["Cisco Digital Network Architecture Center (DNA Center)"],"published":"2020-08-26","related":[{"cvss_score":9.6,"headline":"Cisco DNA Center Command Runner Command Injection Vulnerability","id":"CVE-2021-1264","kev_date_added":null,"published":"2021-01-20"},{"cvss_score":8,"headline":"Cisco DNA Center Privilege Escalation Vulnerability","id":"CVE-2023-20055","kev_date_added":null,"published":"2023-03-23"},{"cvss_score":7.7,"headline":"Cisco DNA Center Information Disclosure Vulnerability","id":"CVE-2021-1265","kev_date_added":null,"published":"2021-01-20"},{"cvss_score":7.5,"headline":"Cisco Catalyst Center Arbitrary File Read Vulnerability","id":"CVE-2026-20191","kev_date_added":null,"published":"2026-07-01"},{"cvss_score":7.5,"headline":"Cisco Catalyst Center Static SSH Host Key Vulnerability","id":"CVE-2024-20350","kev_date_added":null,"published":"2024-09-25"},{"cvss_score":7.5,"headline":"Cisco DNA Center Information Disclosure Vulnerability","id":"CVE-2020-3411","kev_date_added":null,"published":"2020-08-17"},{"cvss_score":7.4,"headline":"Cisco DNA Center Certificate Validation Vulnerability","id":"CVE-2021-1134","kev_date_added":null,"published":"2021-06-29"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2024-11-13","vendors":["Cisco"]},"summary":"Unauthenticated attackers can execute arbitrary scripts or access sensitive data via XSS in Cisco DNA Center's web interface.","url":"https://insights.sbomify.com/CVE-2020-3466/"}
