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-2022-20778 in the wild and no public exploit code.\n\nAffected product: Cisco Webex Meetings. 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-2022-20778/ (Markdown: https://insights.sbomify.com/CVE-2022-20778/index.md)","id":"CVE-2022-20778","markdown":"https://insights.sbomify.com/CVE-2022-20778/index.md","name":"CVE-2022-20778","record":{"aliases":["GHSA-g79w-q84v-cx7q"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["code_execution","data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Cisco Webex Meetings","requires_auth":"none","summary":"An unauthenticated remote attacker can execute arbitrary script code or access sensitive browser-based information by tricking a user into clicking a malicious link in Cisco Webex Meetings.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"cisco","cpe":[{"product":"webex_meetings","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 authentication component of Cisco Webex Meetings could allow an unauthenticated, remote attacker to conduct a cross-site scripting (XSS) attack against a user of the web-based interface. This vulnerability is due to insufficient validation of user-supplied input by the web-based interface of the authentication component of Cisco Webex Meetings. An attacker could exploit this vulnerability by persuading a user of the interface to click a maliciously 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 Webex Meetings Cross-Site Scripting Vulnerability","id":"CVE-2022-20778","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"cisco:webex_meetings","products":["cisco:webex_meetings"],"type":"xss","year":"2022"},"n_packages":0,"n_references":1,"next":{"headline":"Cisco Enterprise NFV Infrastructure Software Vulnerabilities","id":"CVE-2022-20779"},"packages":[],"prev":{"headline":"Cisco Enterprise NFV Infrastructure Software Vulnerabilities","id":"CVE-2022-20777"},"products":["Cisco Webex Meetings"],"published":"2022-04-21","related":[{"cvss_score":9.6,"headline":"Memory corruption in Cisco WebEx Recording Format and Advanced Recording Format Players","id":"CVE-2017-12368","kev_date_added":null,"published":"2017-11-30"},{"cvss_score":9.6,"headline":"Memory corruption in Cisco WebEx Recording Format and Advanced Recording Format Players","id":"CVE-2017-12369","kev_date_added":null,"published":"2017-11-30"},{"cvss_score":9.6,"headline":"Memory corruption in Cisco WebEx Recording Format and Advanced Recording Format Players","id":"CVE-2017-12370","kev_date_added":null,"published":"2017-11-30"},{"cvss_score":9.6,"headline":"Memory corruption in Cisco WebEx Recording Format and Advanced Recording Format Players","id":"CVE-2017-12371","kev_date_added":null,"published":"2017-11-30"},{"cvss_score":9.6,"headline":"Memory corruption in Cisco WebEx Recording Format and Advanced Recording Format Players","id":"CVE-2017-12372","kev_date_added":null,"published":"2017-11-30"},{"cvss_score":8.8,"headline":"Cisco Webex Meetings Desktop App for Mac Update Feature Code Execution Vulnerability","id":"CVE-2020-3342","kev_date_added":null,"published":"2020-06-18"},{"cvss_score":8.1,"headline":"Cisco Webex Meetings and Cisco Webex Meetings Server Token Handling Unauthorized Access Vulnerability","id":"CVE-2020-3361","kev_date_added":null,"published":"2020-06-18"}],"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":"2024-11-06","vendors":["Cisco"]},"summary":"An unauthenticated remote attacker can execute arbitrary script code or access sensitive browser-based information by tricking a user into clicking a malicious link in Cisco Webex Meetings.","url":"https://insights.sbomify.com/CVE-2022-20778/"}
