An attacker needs administrator access to exploit it, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2020-3355 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-2020-3355/ (Markdown: https://insights.sbomify.com/CVE-2020-3355/index.md)","id":"CVE-2020-3355","markdown":"https://insights.sbomify.com/CVE-2020-3355/index.md","name":"CVE-2020-3355","record":{"aliases":["GHSA-4q6v-8h4w-56xh"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["code_execution","data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Cisco DCNM","requires_auth":"high_privilege","summary":"An authenticated admin can inject malicious scripts into the Cisco DCNM interface, allowing execution of arbitrary code or access to sensitive browser data.","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":4.8,"severity":"medium","source":"cna","vector":"CVSS:3.0/AV:N/AC:L/PR:H/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":"A vulnerability in the web-based management interface of Cisco Data Center Network Manager (DCNM) could allow an authenticated, remote attacker with administrative credentials to conduct a cross-site scripting (XSS) attack against a user of the interface. The vulnerability is due to insufficient input validation by the web-based management interface. An attacker could exploit this vulnerability by inserting malicious data into a specific data field in the interface. 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. To exploit this vulnerability, the attacker would need administrative credentials on the affected device.","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 Stored Cross-Site Scripting Vulnerability","id":"CVE-2020-3355","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 Stored Cross-Site Scripting Vulnerability","id":"CVE-2020-3356"},"packages":[],"prev":{"headline":"Cisco Data Center Network Manager Stored Cross-Site Scripting Vulnerability","id":"CVE-2020-3354"},"products":["Cisco Data Center Network Manager"],"published":"2020-06-18","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":"2024-11-15","vendors":["Cisco"]},"summary":"An authenticated admin can inject malicious scripts into the Cisco DCNM interface, allowing execution of arbitrary code or access to sensitive browser data.","url":"https://insights.sbomify.com/CVE-2020-3355/"}
