Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2020-3406 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-2020-3406/ (Markdown: https://insights.sbomify.com/CVE-2020-3406/index.md)","id":"CVE-2020-3406","markdown":"https://insights.sbomify.com/CVE-2020-3406/index.md","name":"CVE-2020-3406","record":{"aliases":["GHSA-43p9-75r2-vgfm"],"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 data by tricking a user into clicking a crafted link in the Cisco SD-WAN vManage interface.","user_interaction":"not_required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"cisco","cpe":[{"product":"sd-wan_firmware","vendor":"cisco"}],"cvss":{"score":6.4,"severity":"medium","source":"cna","vector":"CVSS:3.0/AV:N/AC:L/PR:L/UI:N/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":"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 of the interface. 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-2020-3406","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 IOS XE Software RESTCONF and NETCONF-YANG Access Control List Denial of Service Vulnerability","id":"CVE-2020-3407"},"packages":[],"prev":{"headline":"Cisco SD-WAN vManage Software XML External Entity Vulnerability","id":"CVE-2020-3405"},"products":["Cisco SD-WAN vManage"],"published":"2020-07-16","related":[{"cvss_score":8.8,"headline":"Cisco SD-WAN vManage Software Directory Traversal Vulnerability","id":"CVE-2020-3381","kev_date_added":null,"published":"2020-07-16"},{"cvss_score":8.8,"headline":"Cisco SD-WAN Solution Local Privilege Escalation Vulnerability","id":"CVE-2020-3115","kev_date_added":null,"published":"2020-01-26"},{"cvss_score":8.8,"headline":"Cisco SD-WAN Solution Privilege Escalation Vulnerability","id":"CVE-2019-1626","kev_date_added":null,"published":"2019-06-20"},{"cvss_score":8.6,"headline":"Cisco SD-WAN Solution Software Denial of Service Vulnerability","id":"CVE-2020-3351","kev_date_added":null,"published":"2020-07-16"},{"cvss_score":8.6,"headline":"Cisco SD-WAN vEdge Routers Denial of Service Vulnerability","id":"CVE-2020-3369","kev_date_added":null,"published":"2020-07-16"},{"cvss_score":7.8,"headline":"Cisco SD-WAN vManage Software Command Injection Vulnerability","id":"CVE-2020-3388","kev_date_added":null,"published":"2020-07-16"},{"cvss_score":7.8,"headline":"Cisco SD-WAN Solution Command Injection Vulnerability","id":"CVE-2020-3266","kev_date_added":null,"published":"2020-03-19"}],"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 data by tricking a user into clicking a crafted link in the Cisco SD-WAN vManage interface.","url":"https://insights.sbomify.com/CVE-2020-3406/"}
