This vulnerability is due to insufficient validation of user-supplied input. An attacker could exploit this vulnerability by persuading a user of an affected interface to view a page containing malicious HTML or script content. 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. To exploit this vulnerability, the attacker must have valid credentials to access the web-based management interface of the affected device.","severity":{"version":"3.1","score":5.5,"vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:C/C:L/I:L/A:N","level":"medium","assessor":"cna","from":"cve"},"epss":{"day":"2026-11-10","score":0.00459,"percentile":0.40085,"model":"v2026.06.15"},"facts":{"in_kev":false,"known_exploited":false,"public_exploit":false,"fix_available":false},"cwes":["CWE-79"],"published":"2023-11-21T18:45:33Z","modified":"2026-06-17T05:30:11Z","products":[{"vendor":"cisco","product":"cisco ip phones with multiplatform firmware"},{"vendor":"cisco","product":"cisco session initiation protocol (sip) software"},{"vendor":"cisco","product":"ip_dect_110_firmware"},{"vendor":"cisco","product":"ip_dect_210_firmware"},{"vendor":"cisco","product":"unified_ip_phone_6901_firmware"},{"vendor":"cisco","product":"unified_sip_phone_3905_firmware"}],"references":[{"url":"https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-uipphone-xss-NcmUykqA","tags":["x_transferred","Vendor Advisory"]},{"url":"https://nvd.nist.gov/vuln/detail/CVE-2023-20265"},{"url":"https://github.com/advisories/GHSA-qhgp-x2hc-2hvc"}],"sources":{"cve":[{"id":"CVE-2023-20265","description":"A vulnerability in the web-based management interface of a small subset of Cisco IP Phones could allow an authenticated, remote attacker to conduct a stored cross-site scripting (XSS) attack against a user of the interface on an affected device.
