Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2020-3518 in the wild and no public exploit code.\n\nAffected product: Cisco Data Center Network 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-2020-3518/ (Markdown: https://insights.sbomify.com/CVE-2020-3518/index.md)","id":"CVE-2020-3518","markdown":"https://insights.sbomify.com/CVE-2020-3518/index.md","name":"CVE-2020-3518","record":{"aliases":["GHSA-f87w-3h49-3cqr"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["code_execution","data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Data Center Network Manager","requires_auth":"low_privilege","summary":"Authenticated attackers can execute arbitrary scripts or steal browser data via XSS in Cisco DCNM web interface.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"cisco","cpe":[{"product":"data_center_network_manager","vendor":"cisco"}],"cvss":{"score":6.5,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:L","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 Cisco Data Center Network Manager (DCNM) Software could allow an authenticated, remote attacker to conduct a cross-site scripting (XSS) attack against a user of the interface of the affected software. 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 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 Data Center Network Manager Cross-Site Scripting Vulnerability","id":"CVE-2020-3518","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"cisco:data_center_network_manager","products":["cisco:data_center_network_manager"],"type":"xss","year":"2020"},"n_packages":0,"n_references":1,"next":{"headline":"Cisco Data Center Network Manager Path Traversal Vulnerability","id":"CVE-2020-3519"},"packages":[],"prev":{"headline":"Cisco FXOS and NX-OS Software Cisco Fabric Services Denial of Service Vulnerability","id":"CVE-2020-3517"},"products":["Cisco Data Center Network Manager"],"published":"2020-08-26","related":[{"cvss_score":9.8,"headline":"Cisco Data Center Network Manager Authentication Bypass Vulnerability","id":"CVE-2020-3382","kev_date_added":null,"published":"2020-07-31"},{"cvss_score":9.8,"headline":"Cisco Data Center Network Manager Authentication Bypass Vulnerabilities","id":"CVE-2019-15975","kev_date_added":null,"published":"2020-01-06"},{"cvss_score":9.8,"headline":"Cisco Data Center Network Manager Authentication Bypass Vulnerabilities","id":"CVE-2019-15976","kev_date_added":null,"published":"2020-01-06"},{"cvss_score":9.8,"headline":"Cisco Data Center Network Manager Authentication Bypass Vulnerabilities","id":"CVE-2019-15977","kev_date_added":null,"published":"2020-01-06"},{"cvss_score":9.8,"headline":"Cisco Data Center Network Manager Authentication Bypass Vulnerability","id":"CVE-2019-1619","kev_date_added":null,"published":"2019-06-27"},{"cvss_score":9.8,"headline":"Cisco Data Center Network Manager Arbitrary File Upload and Remote Code Execution Vulnerability","id":"CVE-2019-1620","kev_date_added":null,"published":"2019-06-27"},{"cvss_score":8.8,"headline":"Cisco Data Center Network Manager SQL Injection Vulnerabilities","id":"CVE-2021-1247","kev_date_added":null,"published":"2021-01-20"}],"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":"Authenticated attackers can execute arbitrary scripts or steal browser data via XSS in Cisco DCNM web interface.","url":"https://insights.sbomify.com/CVE-2020-3518/"}
