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.","publishedAt":"2023-11-21T18:45:33.998Z","updatedAt":"2024-08-29T20:02:00.535Z","severity":{"score":5.5,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:C/C:L/I:L/A:N","source":"cisco"},"assigner":"cisco","products":["Cisco Cisco IP Phones with Multiplatform Firmware","Cisco Cisco Session Initiation Protocol (SIP) Software"],"affected":[{"vendor":"Cisco","product":"Cisco IP Phones with Multiplatform Firmware","versions":[{"version":"4.5","status":"affected"},{"version":"4.6 MSR1","status":"affected"},{"version":"4.7.1","status":"affected"},{"version":"4.8.1","status":"affected"},{"version":"4.8.1 SR1","status":"affected"},{"version":"5.0.1","status":"affected"},{"version":"5.1.1","status":"affected"},{"version":"5.1.2","status":"affected"}]},{"vendor":"Cisco","product":"Cisco Session Initiation Protocol (SIP) Software","versions":[{"version":"9.3(1)","status":"affected"},{"version":"9.1(1)","status":"affected"},{"version":"9.3(1)SR2","status":"affected"},{"version":"9.4(1)","status":"affected"},{"version":"9.2(2)","status":"affected"},{"version":"9.2(1)","status":"affected"},{"version":"9.3(1)SR1","status":"affected"},{"version":"9.4(1)SR2","status":"affected"},{"version":"9.4(1)SR1","status":"affected"}]}],"references":["https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-uipphone-xss-NcmUykqA"],"weaknesses":["CWE-79"],"ingestedAt":"2026-10-29T20:05:36.141Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2023/20xxx/CVE-2023-20265.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.1","cveMetadata":{"cveId":"CVE-2023-20265","state":"PUBLISHED","datePublished":"2023-11-21T18:45:33.998Z","dateUpdated":"2024-08-29T20:02:00.535Z","assignerShortName":"cisco","assignerOrgId":"d1c1063e-7a18-46af-9102-31f8928bc633","dateReserved":"2022-10-27T18:47:50.373Z"},"containers":{"cna":{"descriptions":[{"lang":"en","value":"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.
