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.","state":"PUBLIC","assigner":"psirt@cisco.com","published_at":"2022-04-21 19:15:00","updated_at":"2023-11-07 03:42:00"},"problem_types":["CWE-79"],"metrics":[],"references":[{"url":"https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-webex-xss-w47AMqAk","name":"20220420 Cisco Webex Meetings Cross-Site Scripting Vulnerability","refsource":"CISCO","tags":[],"title":"","mime":"text/html","httpstatus":"200","archivestatus":"404"},{"url":"https://www.cve.org/CVERecord?id=CVE-2022-20778","name":"CVE Program record","refsource":"CVE.ORG","tags":["canonical"]},{"url":"https://nvd.nist.gov/vuln/detail/CVE-2022-20778","name":"NVD vulnerability detail","refsource":"NVD","tags":["canonical","analysis"]}],"affected":[],"timeline":[],"solutions":[],"workarounds":[],"exploits":[],"credits":[],"nvd_cpes":[{"cve_year":"2022","cve_id":"20778","vulnerable":"1","versionEndIncluding":"","cpe1":"cpe","cpe2":"2.3","cpe3":"a","cpe4":"cisco","cpe5":"webex_meetings","cpe6":"-","cpe7":"*","cpe8":"*","cpe9":"*","cpe10":"*","cpe11":"*","cpe12":"*","cpe13":"*"}],"vendor_comments":[],"enrichments":{"kev":null,"epss":null,"legacy_qids":[]},"source_records":{"cve_program":{"CVE_data_meta":{"ASSIGNER":"psirt@cisco.com","DATE_PUBLIC":"2022-04-20T16:00:00","ID":"CVE-2022-20778","STATE":"PUBLIC","TITLE":"Cisco Webex Meetings Cross-Site Scripting Vulnerability"},"affects":{"vendor":{"vendor_data":[{"product":{"product_data":[{"product_name":"Cisco Webex Meetings ","version":{"version_data":[{"version_value":"n/a"}]}}]},"vendor_name":"Cisco"}]}},"data_format":"MITRE","data_type":"CVE","data_version":"4.0","description":{"description_data":[{"lang":"eng","value":"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.
