Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2020-3590 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-2020-3590/ (Markdown: https://insights.sbomify.com/CVE-2020-3590/index.md)","id":"CVE-2020-3590","markdown":"https://insights.sbomify.com/CVE-2020-3590/index.md","name":"CVE-2020-3590","record":{"aliases":["GHSA-9xmx-xq79-cppv"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["code_execution","data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"SD-WAN management software","requires_auth":"low_privilege","summary":"An authenticated attacker can execute arbitrary scripts or access sensitive browser data via XSS in the Cisco SD-WAN vManage web interface.","user_interaction":"not_required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"cisco","cpe":[{"product":"catalyst_sd-wan_manager","vendor":"cisco"},{"product":"sd-wan_vmanage","vendor":"cisco"}],"cvss":{"score":6.4,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"A vulnerability in the web-based management interface of the Cisco SD-WAN vManage Software could allow an authenticated, remote attacker to conduct a cross-site scripting (XSS) attack against a user. The vulnerability exists because the web-based management interface does not properly validate user-supplied input. An attacker could exploit this vulnerability by persuading a user to click a crafted link. A successful exploit could allow the attacker to execute arbitrary script code in the context of the 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 SD-WAN vManage Software Cross-Site Scripting Vulnerability","id":"CVE-2020-3590","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"cisco:catalyst_sd-wan_manager","products":["cisco:catalyst_sd-wan_manager"],"type":"xss","year":"2020"},"n_packages":0,"n_references":1,"next":{"headline":"Cisco SD-WAN vManage Cross-Site Scripting Vulnerability","id":"CVE-2020-3591"},"packages":[],"prev":{"headline":"Cisco Identity Services Engine Cross-Site Scripting Vulnerability","id":"CVE-2020-3589"},"products":["Cisco SD-WAN vManage"],"published":"2020-11-06","related":[{"cvss_score":10,"headline":"Cisco Catalyst SD-WAN Controller Authentication Bypass","id":"CVE-2026-20182","kev_date_added":"2026-05-14","published":"2026-05-14"},{"cvss_score":10,"headline":"Cisco Catalyst SD-WAN Controller and Manager Authentication Bypass","id":"CVE-2026-20127","kev_date_added":"2026-02-25","published":"2026-02-25"},{"cvss_score":9.8,"headline":"Cisco Catalyst SD-WAN Manager Hex Encoding","id":"CVE-2026-76504","kev_date_added":"2026-09-30","published":"2026-09-30"},{"cvss_score":7.8,"headline":"Cisco Catalyst SD-WAN Manager Improper Encoding or Escaping of Output","id":"CVE-2026-20245","kev_date_added":"2026-06-09","published":"2026-06-04"},{"cvss_score":7.8,"headline":"Cisco SD-WAN Path Traversal","id":"CVE-2022-20775","kev_date_added":"2026-02-25","published":"2022-09-30"},{"cvss_score":7.5,"headline":"Cisco Catalyst SD-WAN Manager Storing Passwords in a Recoverable Format","id":"CVE-2026-20128","kev_date_added":"2026-04-20","published":"2026-02-25"},{"cvss_score":6.5,"headline":"Cisco Catalyst SD-WAN Manager Directory or Path Traversal","id":"CVE-2026-20262","kev_date_added":"2026-06-15","published":"2026-06-15"}],"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":"An authenticated attacker can execute arbitrary scripts or access sensitive browser data via XSS in the Cisco SD-WAN vManage web interface.","url":"https://insights.sbomify.com/CVE-2020-3590/"}
