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-2021-34742 in the wild and no public exploit code.\n\nAffected product: Cisco Vision Dynamic Signage Director. 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-2021-34742/ (Markdown: https://insights.sbomify.com/CVE-2021-34742/index.md)","id":"CVE-2021-34742","markdown":"https://insights.sbomify.com/CVE-2021-34742/index.md","name":"CVE-2021-34742","record":{"aliases":["GHSA-m49x-9cgf-q686"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["code_execution","data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Cisco Vision Signage Director","requires_auth":"none","summary":"Unauthenticated attackers can execute arbitrary scripts or access sensitive data by tricking users into clicking crafted links in the Cisco Vision Dynamic Signage Director interface.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"cisco","cpe":[{"product":"vision_dynamic_signage_director","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 web-based management interface of Cisco Vision Dynamic Signage Director could allow an unauthenticated, remote attacker to conduct a cross-site scripting (XSS) attack against a user of the interface on an affected device. This vulnerability is due to insufficient validation of user-supplied input by the web-based management interface. 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 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 Vision Dynamic Signage Director Reflected Cross-Site Scripting Vulnerability","id":"CVE-2021-34742","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"Cisco Webex Software Application Authorization Bypass Vulnerability","id":"CVE-2021-34743"},"packages":[],"prev":{"headline":"Cisco Email Security Appliance Denial of Service Vulnerability","id":"CVE-2021-34741"},"products":["Cisco Vision Dynamic Signage Director"],"published":"2021-10-06","related":[{"cvss_score":9.1,"headline":"Cisco Vision Dynamic Signage Director REST API Authentication Bypass Vulnerability","id":"CVE-2019-1917","kev_date_added":null,"published":"2019-07-17"},{"cvss_score":6.5,"headline":"Cisco Vision Dynamic Signage Director Missing Authentication Vulnerability","id":"CVE-2020-3598","kev_date_added":null,"published":"2020-10-08"},{"cvss_score":6.5,"headline":"Cisco Vision Dynamic Signage Director Authentication Bypass Vulnerability","id":"CVE-2019-16004","kev_date_added":null,"published":"2020-09-23"},{"cvss_score":6.3,"headline":"Cisco Vision Dynamic Signage Director Role-Based Access Control Vulnerability","id":"CVE-2020-3485","kev_date_added":null,"published":"2020-08-26"},{"cvss_score":5.5,"headline":"Cisco Vision Dynamic Signage Director Stored Cross-Site Scripting Vulnerability","id":"CVE-2020-3491","kev_date_added":null,"published":"2020-08-26"},{"cvss_score":5.3,"headline":"Cisco Vision Dynamic Signage Director Directory Traversal Information Disclosure Vulnerability","id":"CVE-2020-3484","kev_date_added":null,"published":"2020-08-26"}],"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":"2024-11-07","vendors":["Cisco"]},"summary":"Unauthenticated attackers can execute arbitrary scripts or access sensitive data by tricking users into clicking crafted links in the Cisco Vision Dynamic Signage Director interface.","url":"https://insights.sbomify.com/CVE-2021-34742/"}
