{"id":"CVE-2020-3136","aliases":["EUVD-2020-24407","GHSA-7qqq-6cxm-7rmg"],"status":"published","title":"Cisco Jabber Guest Cross-Site Scripting Vulnerability","description":"A vulnerability in the web-based management interface of Cisco Jabber Guest could allow an unauthenticated, remote attacker to conduct a cross-site scripting (XSS) attack against a user of the web-based management interface of an affected device. The vulnerability exists because the web-based management interface of the affected device does not properly validate user-supplied input. An attacker could exploit this vulnerability by persuading a user to click a malicious link. A successful exploit could allow the attacker to execute arbitrary script code in the context of the affected interface or to access sensitive, browser-based information. This vulnerability affects Cisco Jabber Guest releases 11.1(2) and earlier.","severity":{"version":"3.0","score":6.1,"vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N","level":"medium","assessor":"cna","from":"cve"},"epss":{"day":"2026-11-08","score":0.0084,"percentile":0.58116,"model":"v2026.06.15"},"facts":{"in_kev":false,"known_exploited":false,"public_exploit":false,"fix_available":false},"cwes":["CWE-79"],"published":"2020-01-26T04:30:17Z","modified":"2026-06-17T03:17:26Z","products":[{"vendor":"cisco","product":"cisco jabber guest"},{"vendor":"cisco","product":"jabber_guest"}],"references":[{"url":"https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-jabber-guest-xss-6urXhkqv","tags":["vendor-advisory","x_refsource_CISCO","x_transferred","Vendor Advisory"]},{"url":"https://nvd.nist.gov/vuln/detail/CVE-2020-3136"},{"url":"https://github.com/advisories/GHSA-7qqq-6cxm-7rmg"}],"sources":{"cve":[{"id":"CVE-2020-3136","title":"Cisco Jabber Guest Cross-Site Scripting Vulnerability","description":"A vulnerability in the web-based management interface of Cisco Jabber Guest could allow an unauthenticated, remote attacker to conduct a cross-site scripting (XSS) attack against a user of the web-based management interface of an affected device.
