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-2023-20104 in the wild and no public exploit code.\n\nAffected product: Cisco Webex Teams. 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-2023-20104/ (Markdown: https://insights.sbomify.com/CVE-2023-20104/index.md)","id":"CVE-2023-20104","markdown":"https://insights.sbomify.com/CVE-2023-20104/index.md","name":"CVE-2023-20104","record":{"aliases":["GHSA-8cc5-x8g7-4w8h"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["code_execution","data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Cisco Webex App","requires_auth":"none","summary":"An unauthenticated attacker can execute arbitrary script code or access sensitive browser information via a crafted file and URL in Cisco Webex App for Web.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"cisco","cpe":[{"product":"webex_teams","vendor":"cisco"}],"cvss":{"score":6.1,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/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 file upload functionality of Cisco Webex App for Web could allow an unauthenticated, remote attacker to conduct a cross-site scripting (XSS) attack against a user of the interface. This vulnerability is due to insufficient validation of user-supplied input. An attacker could exploit this vulnerability by sending an arbitrary file to a user and persuading that user to browse to a specific URL. 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 Webex App for Web Cross-Site Scripting Vulnerability","id":"CVE-2023-20104","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2023"},"n_packages":0,"n_references":1,"next":{"headline":"Privilege escalation in Cisco TelePresence Video Communication Server (VCS) Expressway","id":"CVE-2023-20105"},"packages":[],"prev":{"headline":"Cisco Secure Network Analytics Remote Code Execution Vulnerability","id":"CVE-2023-20103"},"products":["Cisco Webex Teams"],"published":"2023-03-03","related":[{"cvss_score":8.8,"headline":"Cisco Webex App Client-Side Remote Code Execution Vulnerability","id":"CVE-2025-20236","kev_date_added":null,"published":"2025-04-16"},{"cvss_score":8.8,"headline":"Code injection in Cisco Webex Teams unknown","id":"CVE-2018-0387","kev_date_added":null,"published":"2018-07-18"},{"cvss_score":8.7,"headline":"Cisco Webex Teams Information Disclosure and Modification Vulnerability","id":"CVE-2018-0436","kev_date_added":null,"published":"2018-10-05"},{"cvss_score":7.8,"headline":"Cisco Webex Teams Client for Windows DLL Hijacking Vulnerability","id":"CVE-2020-3535","kev_date_added":null,"published":"2020-10-08"},{"cvss_score":7.8,"headline":"Cisco Webex Teams URI Handler Insecure Library Loading Vulnerability","id":"CVE-2019-1636","kev_date_added":null,"published":"2019-01-23"},{"cvss_score":7.5,"headline":"Cisco Webex Teams Logging Feature Command Execution Vulnerability","id":"CVE-2019-1939","kev_date_added":null,"published":"2019-09-05"},{"cvss_score":7.3,"headline":"Cisco Webex Teams for iOS Arbitrary File Upload Vulnerability","id":"CVE-2019-1689","kev_date_added":null,"published":"2019-02-25"}],"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":"2024-10-25","vendors":["Cisco"]},"summary":"An unauthenticated attacker can execute arbitrary script code or access sensitive browser information via a crafted file and URL in Cisco Webex App for Web.","url":"https://insights.sbomify.com/CVE-2023-20104/"}
